Storage package protection should be constructed such that mechanical

damage to the equipment inside the package will not cause a leak of

the refrigerant charge. The maximum number of pieces of equipment

permitted to be stored together will be determined by local regulations.

6. Information on servicing:

1) Checks to the area:

Prior to beginning work on systems containing ﬂammable refrigerants,

safety checks are necessary to ensure that the risk of ignition is minimized.

For repair to the refrigerating system, the following precautions shall be

complied with prior to conducting work on the system.

2) Work procedure:

Work shall be undertaken under a controlled procedure so as to minimize

the risk of a ﬂammable gas or vapour being present while the work is

being performed.

3) General work area:

All maintenance staff and others working in the local area shall be

instructed on the nature of work being carried out. Work in conﬁned spaces

shall be avoided. The area around the workspace shall be sectioned off.

Ensure that the conditions within the area have been made safe by control

of ﬂammable material.

4) Checking for presence of refrigerant:

The area shall be checked with an appropriate refrigerant detector prior to

and during work, to ensure the technician is aware of potentially ﬂammable

atmospheres. Ensure that the leak detection equipment being used is

suitable for use with ﬂammable refrigerants, i.e. non-sparking, adequately

sealed or intrinsically safe.

5) Presence of ﬁre extinguisher:

If any hot work is to be conducted on the refrigeration equipment or

any associated parts, appropriate ﬁre extinguishing equipment shall be

available to hand. Have a dry powder or CO2 ﬁre extinguisher adjacent to

the charging area.

6) No ignition sources:

No person carrying out work in relation to a refrigeration system which

involves exposing any pipe work that contains or has contained ﬂammable

refrigerant shall use any sources of ignition in such a manner that it may

lead to the risk of ﬁre or explosion. All possible

ignition sources, including cigarette smoking, should be kept sufﬁciently far

away from the site of installation, repairing, removing and disposal, during

which ﬂammable refrigerant can possibly be released to the surrounding

space. Prior to work taking place,

the area around the equipment is to be surveyed to make sure that there

are no ﬂammable hazards or ignition risks. No Smoking signs shall be

displayed.

7) Ventilated area:

Ensure that the area is in the open or that it is adequately ventilated

before breaking into the system or conducting any hot work. A degree

of ventilation shall continue during the period that the work is carried

out. The ventilation should safely disperse any released refrigerant and

preferably expel it externally into the atmosphere.

8) Checks to the refrigeration equipment:

Where electrical components are being changed, they shall be ﬁt for the

purpose and to the correct speciﬁcation. At all times the manufacturer’s

maintenance and service guidelines shall be followed. If in doubt consult

the manufacturer’s technical department for assistance. The following

checks shall be applied to installations using ﬂammable refrigerants:

a. The charge size is in accordance with the room size within which the

refrigerant containing

parts are installed;

b. The ventilation machinery and outlets are operating adequately and are

not obstructed;

c. If an indirect refrigerating circuit is being used, the secondary circuit

shall be checked for the presence of refrigerant; Marking to the equipment

continues to be visible and legible. Markings and signs that are illegible

shall be corrected;

d. Refrigeration pipe or components are installed in a position where they

are unlikely to be exposed to any substance which may corrode refrigerant

containing components, unless the components are constructed of

materials which are inherently resistant to being corroded or are suitably

protected against being so corroded.

9) Checks to electrical devices:

Repair and maintenance to electrical components shall include initial

safety checks and component inspection procedures. If a fault exists that

could compromise safety, then no electrical supply shall be connected to

the circuit until it is satisfactorily dealt with. If the fault cannot be corrected

immediately but it is necessary to continue operation, an adequate

temporary solution shall be used. This shall be reported to the owner of

the equipment so all parties are advised. Initial safety checks shall include:

a. That capacitors are discharged: this shall be done in a safe manner to

avoid possibility of sparking;

b. That there no live electrical components and wiring are exposed while

charging, recovering or purging the system;

c. That there is continuity of earth bonding.

7. Repair to intrinsically safe components:

Do not apply any permanent inductive or capacitance loads to the circuit

without ensuring that this will not exceed the permissible voltage and

current permitted for the equipment in use. Intrinsically safe components

are the only types that can be worked on while live in the presence of a

ﬂammable atmosphere. The test apparatus shall be at the correct rating.

Replace components only with parts speciﬁed by the manufacturer. Other

parts may result in the ignition of refrigerant in the atmosphere from a

leak.

8. Cabling:

Check that cabling will not be subject to wear, corrosion, excessive

pressure, vibration, sharp edges or any other adverse environmental

effects. The check shall also take into account the effects of aging or

continual vibration from sources such as compressors or fans.

9. Detection of ﬂammable refrigerants

Under no circumstances shall potential sources of ignition be used in the

searching for or detection of refrigerant leaks. A halide torch (or any other

detector using a naked ﬂame) shall not be used.

10. Leak detection methods:

The following leak detection methods are deemed acceptable for systems

containing ﬂammable refrigerants. Electronic leak detectors shall be used

to detect ﬂammable refrigerants, but the sensitivity may not be adequate,

or may need re-calibration. (Detection equipment shall be calibrated in a

refrigerant-free area.) Ensure that the detector is not a potential source of

ignition and is suitable for the refrigerant used. Leak detection equipment

shall be set at a percentage of the LFL of the refrigerant and shall be

calibrated to the refrigerant employed and the appropriate percentage of

gas (25 % maximum) is conﬁrmed. Leak detection ﬂuids are suitable for

use with most refrigerants but the use of detergents containing chlorine

shall be avoided as the chlorine may react with the refrigerant and corrode

the copper pipe-work. If a leak is suspected, all naked ﬂames shall be

removed/extinguished. If a leakage of refrigerant is found which requires

brazing, all of the refrigerant shall be recovered from the system, or

isolated (by means of shut off valves) in a part of the system remote from

the leak. Oxygen free nitrogen (OFN) shall then be purged through the

system both before and during the brazing process.

11. Removal and evacuation

When breaking into the refrigerant circuit to make repairs or for any other

purpose conventional procedures shall be used. However, it is important

that best practice is followed since ﬂammability is a consideration. The

following procedure shall be adhered to: Remove refrigerant; Purge the

circuit with inert gas; Evacuate; Purge again with inert gas; Open the

circuit by cutting or brazing. The refrigerant charge shall be recovered into

the correct recovery cylinders. The system shall be ﬂushed with OFN to

render the unit safe. This process may need to be repeated several times.

Compressed air or oxygen shall not be used for this task. Flushing shall be

achieved by breaking the vacuum in the system with OFN and continuing

to ﬁll until the working pressure is achieved, then venting to atmosphere,

and ﬁnally pulling down to a vacuum. This process shall be repeated until

no refrigerant is within the system. When the ﬁnal OFN charge is used, the

system shall be vented down to atmospheric pressure to enable work to

take place. This operation is absolutely vital if brazing operations on the

pipe-work are to take place. Ensure that the outlet for the vacuum pump is

not close to any ignition sources and there is ventilation available.

12. Charging procedures:

In addition to conventional charging procedures, the following

requirements shall be followed. Ensure that contamination of different

refrigerants does not occur when using charging equipment. Hoses or

lines shall be as short as possible to minimise the amount of refrigerant

contained in them. Cylinders shall be kept upright. Ensure that the

refrigeration system is earthed prior to charging the system with

refrigerant. Label the system when charging is complete (if not already).

Extreme care shall be taken not to overﬁll the refrigeration system. Prior

to recharging the system it shall be pressure tested with OFN. The system

shall be leak tested on completion of charging but prior to commissioning.

A follow up leak test shall be carried out prior to leaving the site.

13. Decommissioning:

Before carrying out this procedure, it is essential that the technician is

completely familiarwith the equipment and all its detail. It is recommended

good practice that all refrigerants are recovered safely. Prior to the task

being carried out, an oil and refrigerant sample shall be taken in case

analysis is required prior to re-use of reclaimed refrigerant. It is essential

that electrical power is available before the task is commenced.

a. Become familiar with the equipment and its operation.

b. Isolate system electrically.

c. Before attempting the procedure ensure that: Mechanical handling

equipment is available, if required, for handling refrigerant cylinders;

All personal protective equipment is available and being used correctly;

The recovery process is supervised at all times by a competent person;

Recovery equipment and cylinders conform to the appropriate standards.

d. Pump down refrigerant system, if possible.

e. If a vacuum is not possible, make a manifold so that refrigerant can be

removed from various parts of the system.

f. Make sure that cylinder is situated on the scales before recovery takes

place.

g. Start the recovery machine and operate in accordance with

manufacturer’s instructions.

h. Do not overﬁll cylinders. (No more than 80 % volume liquid charge).

i. Do not exceed the maximum working pressure of the cylinder, even

temporarily.

j. When the cylinders have been ﬁlled correctly and the process completed,

make sure that the cylinders and the equipment are removed from site

promptly and all isolation valves on the equipment are closed off.

k. Recovered refrigerant shall not be charged into another refrigeration

system unless it has been cleaned and checked.

14. Labeling:

Equipment shall be labelled stating that it has been de-commissioned

and emptied of refrigerant. The label shall be dated and signed. Ensure

that there are labels on the equipment stating the equipment contains

ﬂammable refrigerant.

15. Recovery:

When removing refrigerant from a system, either for servicing or

decommissioning, it is recommended good practice that all refrigerants

are removed safely. When transferring refrigerant into cylinders, ensure

that only appropriate refrigerant recovery cylinders are employed. Ensure

that the correct number of cylinders for holding the total system charge

is available. All cylinders to be used are designated for the recovered

refrigerant and labeled for that refrigerant (i.e. special cylinders for the

recovery of refrigerant).

Cylinders shall be complete with pressure relief valve and associated shut-

off valves in good working order. Empty recovery cylinders are evacuated

and, if possible, cooled before recovery occurs. The recovery equipment

shall be in good working order with a set of instructions concerning

the equipment that is at hand and shall be suitable for the recovery of

ﬂammable refrigerants. In addition, a set of calibrated weighing scales

shall be available and in good working order. Hoses shall be complete

with leak-free disconnect couplings and in good condition. Before using

the recovery machine, check that it is in satisfactory working order, has

been properly maintained and that any associated electrical components

are sealed to prevent ignition in the event of a refrigerant release. Consult

manufacturer if in doubt. The recovered refrigerant shall be returned to

the refrigerant supplier in the correct recovery cylinder, and the relevant

Waste Transfer Note arranged. Do not mix refrigerants in recovery units

and especially not in cylinders. If compressors or compressor oils are to be

removed, ensure that they have been evacuated to an acceptable level to

make certain that ﬂammable refrigerant does not

remain within the lubricant. The evacuation process shall be carried out

prior to returning the compressor to the suppliers. Only electric heating to

the compressor body shall be employed to accelerate this process. When

oil is drained from a system, it shall be carried out safely.

NOTE: Check the appliance regularly and refer to TROUBLESHOOTING or

contact our customer support if it shows any of the following signs:

- Power cord or plug is damaged.

- Loud noise, unusual smell or excessive heat.

A.6 Unit Features

This Premium unit has many exciting features which are different than those found on standard PTAC models. The owner must be

familiar with these features in order to fully understand the operation and capability of the unit.

Intelligence–Your Premium unit has an on board computer that utilizes real time diagnostics to prolong the life of your unit. There is

an LED indicator on the control board, behind the front panel, that will ﬂash an error code if the unit has detected some kind of fault condition.

In many cases, the unit will automatically clear the fault condition and continue operating with no interruption. In some cases, the condition

cannot be cleared and the unit will require service. In those cases, an“Fx” failure mode will be displayed on the digital display. For a detailed

list of all error codes and “Fx” conditions, see section M.2, 6-Status LED Indicator Deﬁnitions for further details.

Memory–Your Premium unit also has memory. If power is lost, all of the control settings (setpoint, mode, fanspeed, on/off and

conﬁguration) are remembered. So when power is restored, the unit will start back up in the mode (and conﬁguration) it was in, when power

was lost.

Premium Sound-The unit has 2 fan motors. The outdoor fan motor will run at minimum speed for 10 seconds before the compressor

start to reduce any compressor starting noise.

Random Compressor Restart-To help prevent power surges after a power outage (from many of your PTACS starting at the same

time), the compressor is equipped with a 2:45 to 3:15 random restart delay feature. Whenever the unit is plugged in, or power has been

restarted, a random compressor restart will occur.

Compressor Protection-To prevent short cycling of the compressor and maximize it’s life, there is a random start-up delay of 3

minutes on the compressor and a minimum compressor run time of 3 minutes.

A. IMPORTANT SAFETY AND GENERAL INFORMATION

Automatic Room Freeze Protection–automatically keeps the temperature in the room from getting too cold, where water pipes might

freeze. If the unit is conﬁgured for the freeze protection feature to be active (which is the default condition), then whenever power is supplied to

the unit, and the unit senses the temperature is below 40°F, the fan motor and electric heater are turned on, and will warm the room to 50°F.If

Freeze protection is not required, change the conﬁguration switch to turn the feature off (see section J.3 Dip switches on unit conﬁguration).

Automatic defrost protection –When the outdoor temperature gets too cold (approx. 28°F) and the unit can no longer effectively

heat with the compressor, the unit will automatically switch to electric heating. The unit will then heat with electric heat until the outside

temperature rises enough (approx.40°F), so the compressor can be used again.

Automatic Quick Warmup (for heat pump models only)-If the room temperature falls to 5°F below the set point temperature, the

reverse cycle heat is shut off and the electric strip heat is turned on for one cycle, until heating is satisﬁed.

LED Indicator’s and Buttons The touch pad has buttons for POWER, UP, DOWN, COOL, HEAT, CONSTANT FAN, HIGH, LOW and AUTO.

It also has LEDs that correspond to the mode, fan speed and setpoint operation, to indicate the unit’s status. The LEDs above the CONSTANT

FAN, COOL, and HEAT mode buttons indicate what operating mode is active. The LEDs above the LOW, AUTO, and HIGH buttons indicate the fan

speed that is selected. The LED above the power button is the unit On/Off status LED. If the unit is in ON mode, the LED will be blue. If the unit is

OFF, the LED will go out.

Conﬁgure Fan to Optimize Selected Application Unit can be optimized to selected application by conﬁguring the fan to run in

continuous mode or cycle on and off with the compressor and electric heater. In cycle mode, fan will continue to run for a while after

compressor or electric heater stops in order blow off any residual heat or cool left on coil.

Unit Conﬁguration There are many different conﬁguration possibilities, through both dip switches and the digital keypad, that allow

you to conﬁgure the unit for your exact application. See section J.3 on unit conﬁguration for more details. Following are the conﬁguration

selections that have not previously been mentioned:

Temperature Display The unit can display in either °For °C

Indoor Temperature Sensor Biasing Optimize the room temperature sensor reading to your exact application (one for cooling and an

other for heating).

Emergency Heat (for Heat Pump Only) Disable the compressor during heating mode operation (heat only with Electric Heat).

Display Setpoint or Room Temperature The unit can be conﬁgured to display the room temperature or setpoint only, during heating

and cooling modes. See section J.3 on unit conﬁguration for more details.

Limit the Setpoint Range The unit can be conﬁgured to limit the controlling setpoint range. The display will always show the complete

setpoint range, but the controlling setpoint will be limited to the conﬁgured minimum and maximum setpoint selected. See section J.3 on unit

conﬁguration for more details.

Energy Management (Sometimes known as Front Desk Control) an input is provided so that the unit can be manually disabled from a

different location. If the unit detects 24vac on this input, it will automatically turn itself off. If no voltage is detected on the input, the unit will run

normally.

Wall Thermostat Control A wired wall thermostat can be connected to the unit. If it is, the unit must be conﬁgured to disable the

keypad. See section J.3 on wired inputs and unit conﬁguration for more details.

C. INSTALLATION OF THE UNIT

C.1 Pre-Installation Checkpoints

C.1.1 Before attempting any installation, carefully consider the following points:

Before attempting any installation, carefully consider the following points:

• Inspect all components and accessories for damage before and after installation.

• Remove the cardboard wall sleeve support and grill weatherboard.

• Check for proper wall sleeve installation in accordance with the wall sleeve installation instructions.

• Check for a subbase kit or other means of structural support which is required for ALL installations projecting more than 8” into room.

• Install the recommended Condensate Drain Kits for complete condensate removal.

• Ensure that the chassis is installed in a 16” high x 42” wide wall sleeve that is no deeper than 13 ¾”. A bafﬂe kit is required if the sleeve

exceeds that depth.

• Ensure that chassis and chassis front cover are installed and secured properly.

• Ensure that drapes, bed, bedspread, furniture, etc. DO NOT block either return or discharge air grilles.

• Inspect the condenser air inlet and outlet for any obstructions (shrubbery, etc.)

• Ensure that ‘reset’ button is pressed on LCD device (only on 230V models)

C.1.2 Important Considerations

C.1.3 Introduction to R32 Refrigerants

C.1.4 Additional Notes:

• The installation site should be in a well-ventilated condition.

• The sites for installing and maintaining an air conditioner using Refrigerant R32 should be free from open ﬁre or welding, smoking, drying

oven or any other heat source higher than 1000˚F which easily produces open ﬁre.

• When installing an air conditioner, it is necessary to take appropriate anti-static measures such as wear anti-static clothing and/or gloves.

• It is necessary to choose the site convenient for installation or maintenance wherein the air inlets and outlets of the indoor and outdoor

units should be not surrounded by obstacles or close to any heat source or combustible and/or explosive environment.

• If the indoor unit suffers refrigerant leak during the installation, all the personnel should go out till the refrigerant leaks completely for 15

minutes. If the product is damaged, it is a must to carry such damaged product back to the maintenance station and it is prohibited to weld

the refrigerant pipe or conduct other operations on the user’s site.

• It is necessary to choose the place where the inlet and outlet air of the indoor unit is even.
