Operating Instructions

*Always keep these operating instructions near or on the unit! *

Assembly Instructions

Follow these instructions to ensure that the units are

assembled safely and effectively:

◊ The heat-exchanger must be connected in such a

way that vibrations from the unit may not be trans-

ferred to the piping systems or vice-versa.

◊ Before connecting the unit to an existing warm water

heating system, the boiler and pump must be

checked for adequate capacity.

◊ For maintenance and repairs, we recommend at-

taching a repair switch close to the unit.

◊ After all attachment screws have been tightened

evenly, the fan is to be checked to ensure that it is

running smoothly.

◊ The permissible assembly heights must be ob-

served.

The minimum permissible distances from the floor to

the lower edge of the unit can be found in the table

in the section on unit assembly.

Unit Assembly

The units are intended for assembly under the ceiling.

Adjustable assembly profiles make it possible to adjust

the units easily to suspended ceilings as well.

Safety Instructions

Extensive tests have been conducted on the material,

functionality and quality of the units.

Hazards may nevertheless arise if the unit is used by

persons not familiar with its operation or if the unit is not

used for its intended purpose.

Please make sure to always comply with these safety

instructions:

◊ The relevant local building codes must always be

observed!

◊ The operator is responsible for proper unit assembly,

correct electrical installation and safe operation of the

units.

◊ The units must be set up, mounted and operated in

such a way that employees are not bothered by or

put at risk of radiant heat.

◊ The units may only be attached to sturdy construc-

tions or ceilings made of materials with adequate

bearing capacity.

◊ The units must be attached with sturdy wall mounts

that are fastened to the unit.

◊ Assembly, connection of the heating medium, con-

nection of the electrical system and maintenance

may only be performed by trained and authorised

personnel.

◊ The units may not be set up, assembled or operated

in surroundings susceptible to fire or explosions.

◊ The units must be set up outside of high-traffic

zones, e.g. also cranes.

A safety zone of 1 m must be maintained.

◊ The units may only be operated when mounted.

◊ Safety components such as, for example, protective

grilles, may not be disassembled or taken out of op-

eration.

◊ The units may only be used for their intended pur-

pose within the specified operating ranges and with

approved transport media.

See type plate.

◊ The air intake grille must always be kept free of dirt

and loose objects; the unit outlets may not be

blocked.

◊ Never insert foreign objects into the unit.

◊ The units may not be exposed to a direct stream of

water.

◊ Never let water get inside the units.

◊ All of the unit‘s electrical lines must be protected

from damage, e.g. by animals.

The units are only ensured to function properly if

the initial temperature in the unit supply lines and

the pump capacity are adequate for the selected

class of unit.

Connection to the heating system

Before connecting to the customer heating system, the

heating and pump capacity must be checked to ensure

that they meet the technical requirements of the respec-

tive unit.

The REMKO PWW unit should be connected via shut-

off valve, automatic dehumidifier and screw attach-

ments in the supply and return lines.

Draining in case of frost

It is not possible to statically drain the heat-exchanger

completely. The heat-exchanger can only be completely

drained when compressed air is used.

Connecting the units

REMKO PWW 5000 models are equipped with axial

fans that have external rotary current motors for a volt-

age of 400 V / 3~ / 50 Hz. Switching the two speeds of

the rotary current motor is done with a Y / ∆switch.

Integrated thermal contacts protect the motor.

They switch off the fan motor at a winding temperature

of 130 °C in connection with a suitable switching device

(accessory).

The rotary current motors are connected to the corre-

sponding switching units in accordance with the respec-

tive electrical wiring diagrams.

The corresponding power fuse in the line to the switch-

ing unit must be installed by the customer in line with

the relevant regulations.

The connections in the terminal box of the unit must be

connected to the corresponding switching unit

(accessory).

Connecting the fan motor

Motor with 2 speeds, Y/∆ switch and thermal contacts.

High-speed ∆switch

When the fan is idle, the heating medium supply

must be interrupted.

◊ The units operate on the principle of counter-current:

The water (supply line) usually comes in at the bottom,

the water (return line) usually goes out at the top

◊ Once assembled, the heat-exchanger must be care-

fully ventilated because air pockets in the register

can reduce unit performance.

Important information about frost protection!

To prevent frost damage, a frost protection mechanism

must be attached for temperatures below 0 °C.

There may not be any water in the heat-exchanger for

systems taken out of operation in rooms susceptible to

frost. The remaining water must be blown out with com-

pressed air.

If this is not possible, the heating medium (water) must

be mixed with a suitable anti-freeze.

Restriction of guarantee!

Non-compliance with the relative legal requirements,

operating instructions and unit-specific wiring diagrams

can lead to malfunctions that cause damage.

In cases of non-compliance, the guarantee becomes null

and void!

Low speed Y switch

Connecting several units

If necessary, several units (even of different sizes) can

be operated at the same time via a switching unit

(accessory).

The overall capacity of the connected units may not,

however, exceed the maximum electrical capacity of the

corresponding switching unit.

For thermal motor protection, the thermal contacts of all

motors are to be connected in a row. Follow the sepa-

rate wiring diagrams.

There can never be more than one external regulating

mechanism per switching unit connected at a single time!

Electrical Connection

The requirements of the local energy supply company

as well as installation requirements specific for each

unit must be observed.

The electrical connection may only be made by

trained and authorised personnel.

No guarantee claims can be made for frost damage

on the heat-exchanger!

When connecting the screw attachments of the

heating medium connection, a suitable tool should

be used to apply counter-pressure to prevent dam-

age caused by turning the connection lines.

Service and Care

REMKO PWW units require virtually no maintenance

when operated normally. They should, however, be

checked regularly and, if necessary, cleaned, to ensure

proper operation.

1. Separate all poles of the unit from the power supply

and secure it from being switched on by unauthor-

ised persons.

It is not adequate to switch the unit off via the control

switch on the switching unit!

Initial Operation

Prior to initial operation

Prior to initial operation, the following must be com-

pleted:

1. Check that assembly is mechanically sound.

2. Check that the connection to the customer-installed

heating system is correct.

3. Make sure that hot surfaces, e.g. the supply lines,

are protected against unintentional contact.

4. Make sure that all air outlet openings are opened.

5. Activate the power supply to the switching unit and

switch the unit on via the control switch.

6. Initial operation is prohibited until it is ensured that

the proper assembly and electrical installation corre-

sponds to the provisions of the EU guidelines

89/392/EWG and 73/23/EWG.

During initial operation

1. Measure the power consumption of the fan.

The rated current may not exceed the value speci-

fied on the type plate in each switch phase.

2. Check the control/regulating function of the fan.

3. Check the function of the room thermostat.

If mounted.

4. Check that the fan is running quietly.

5. Check the entire system for any vibrations.

6. Check that the heating medium supply lines have

been properly connected and are impermeable.

2. Wait until the fan stops.

3. Turn off the flow of water and secure it from being

opened on by unauthorised persons.

4. Wait until the heat-exchanger has cooled down.

Cleaning materials

◊ Only clean the unit when dry or with a slightly moist

towel and a soap solution.

◊ Never use high-pressure or steam cleaners.

◊ Do not use abrasive cleaners or cleaners that con-

tain solvent.

◊ Even when the unit is extremely dirty, only use suit-

able cleaning materials.

General care

◊ Keep the inside and outside of the unit free of dust

and other deposits.

◊ Keep the air intake and outlet openings from being

blocked.
