Heat Recovery DC Inverter Multi

VRF Unit

…

Preface

Gree DC Inverter Multi VRF System, with the most advanced technologies in the world,

uses eco-friendly refrigerant R410A as its cooling medium. For correct installation and

operation, please read this manual carefully. Before reading the manual, please note that:

(1) To ensure safety when operating the units, please strictly follow the instructions in this

manual.

(2) The total capacity of running indoor units must not exceed that of the outdoor units.

Otherwise, the cooling (heating) effect of each IDU would be poor.

(3) Make sure that this manual is kept by direct operators and maintainers.

(4) In case of malfunction, please examine the following items and contact our authorized

service centers as soon as possible.

1)Air conditioner’s nameplate (model, cooling capacity, product code, ex-factory date);

2) Malfunction status (detail description of conditions before and after malfunction occurs)

(5) All units have been strictly tested and proved to be qualified before ex-factory. To

avoid damage or operation failure which may be caused by improper disassembly, please do

not disassemble units by yourself. If disassembly is needed, please contact our authorized

service centers.

(6) All graphics and information in this manual are only for reference. Manufacturer

reserves the right for changes in terms of sales or production at any time and without prior

notice.

(7) Under the standby status, the unit will consume a little power for ensuring reliability of

the complete unit, maintaining normal communication and preheating refrigerant. When the

unit won’t be used for a long time, please cut off the power of the complete unit. However,

please preheat it when operating the unit next time.

This appliance can be used by children aged from 8 years and above and persons with

reduced physical, sensory or mental capabilities or lack of experience and knowledge if they

have been given supervision or instruction concerning use of the appliance in a safe way and

understand the hazards involved. Children shall not play with the appliance. Cleaning and

1 Safety Precautions

means items that must be forbidden! Otherwise, it may lead to personal injury or death or

serious damage.

means items that must be followed! Otherwise, it may lead to personal injury or property loss.

Please install the unit

according to instructions

in this manual. Read this

manual carefully before

starting up or checking the

machine.

Installation should be

performed by distributor or

qualified personnel. Do

not install the product by

yourself. Improper

water leakage, electric

shock or fire hazard.

Before installation, please

check the power cord if it

complies with the power

supply requirement on the

nameplate. Make sure the

power supply is safe.

This air conditioner must

be properly grounded

through the receptacle to

avoid electric shock. The

ground wire shouldn’t be

connected with gas pipe,

water pipe, lightning

arrester or telephone line.

When installing,

specialized parts and

accessories must be

used. Otherwise, it may

result in water leakage,

electric shock or fire

hazard.

R410A refrigerant can

produce poisonous gas

once it meets fire, so

please ventilate the room

immediately if refrigerant

leaks out during

installation.

Diameter of power cord

must be large enough.

Damaged power cord or

connecting wire must be

replaced by specialized

electric cable.

After the power cord is

connected, please install

the cover of electric box to

avoid danger.

Nitrogen must be charged

according to technical

requirements.

Short circuit is forbidden.

Do not cancel the

pressure switch,

otherwise unit may be

damaged.

For units with wired

controllers, do not connect

power supply until the

wired controller is well

installed. Otherwise, the

wired controller cannot be

used.

When installation is

finished, please check

and make sure the drain

pipe, pipeline and electric

wire are all well connected

to avoid water leakage,

refrigerant leakage,

electric shock and fire

hazard.

Do not extend fingers or

objects into air outlet or

the return air grille.

If gas heater or petroleum

heater is used in the same

room, please open the

door or window to

maintain good air

circulation, otherwise an

oxygen shortage may

occur,

Heat Recovery DC Inverter Multi VRF Unit

for protecting the

compressor.)

Volatile liquid like thinner

or gasoline will damage

the appearance of air

conditioner. (Please use

soft dry cloth and wet

cloth with mild detergent

to clean unit’s outer case.)

Under cool mode, do not

set the indoor temperature

too low. Keep the

difference between indoor

temp and outdoor temp

within 5℃.

If abnormal condition

occurs (e.g. unpleasant

smell), please turn off the

unit at once and

disconnect power supply.

Then contact Gree

authorized service center.

If the air conditioner

Heat Recovery DC Inverter Multi VRF Unit

2 Product Introduction

Gree Modular Heat Recovery Multi VRF System adopts inverter compressor technology. By

changing the displacement of compressor, stepless capacity regulation can be realized. Various

product lineups are provided with capacity range from 22.4kW to 180kW, and indoor units within a

same system can operate in cooling or heating mode in the meantime. This system can be widely

used in commercial and working area and is especially applicable to places with big load change.

Gree commercial multi VRF system is absolutely your best choice.

(2) The total capacity of indoor units should be within 50%~135% of that of the outdoor unit.

Figure 2

(3) Outdoor units of Modular DC Inverter Heat Recovery System can be connected to multi VRF

indoor units, including cassette type unit, one-way cassette type unit, wall-mounted unit and

duct type unit, as shown in figure 2. When any one of the indoor units receives operating

command, outdoor unit will start operation as per required capacity. When all indoor units stop,

outdoor unit will be shut off. Please note that outdoor unit can’t be connected to indoor unit

directly. Heat pump mode exchanger must be installed between outdoor unit and indoor unit.

3.2 Installation Site

Never do this! This symbol indicates the possibility of death or serious injury.

Always do this! This symbol indicates the possibility of personal injury or property damage.

Select a location which is

strong enough to hold

unit’s weight so that unit

can stand still and erect.

Make sure the unit is not

exposed to sun and rain.

And the location can resist

dust, typhoon and

earthquake.

Please keep the unit away

from inflammable,

explosive and corrosive

gas or waste gas.

Make sure the location

has space for heat

exchange and

maintenance so that unit

can operate reliably with

good ventilation.

ODU and IDU should stay

together as close as

possible to shorten the

length of refrigerant pipe

and reduce bend angles.

Select a location which is

out of children’s reach.

Keep the unit away from

children.
