Preface

Gree DC Inverter Multi VRF System, with the most advanced technologies in the world, uses ecofriendly refrigerant R410A as its cooling medium. For correct installation and operation, please read this manual carefully. Before reading the manual, please note that:

(1) For safety operation, please strictly follow the instructions in this manual.

(2) During operation, the gross rated capacity of working IDU should be within the gross rated

capacity of ODU. Otherwise, IDU’s cooling/heating performance will be reduced. (3) This manual must be in the hands of direct operators or maintenance men. (4) In case of malfunction and operation failure, please examine the following items and contact

our authorized service centers as soon as possible.

1) Nameplate (model, cooling capacity, product code, ex-factory date).

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

(6) All units have been strictly tested and proved to be qualied before ex-factory. To avoid unit

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

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

serve centers for help. (7) 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.

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 user maintenance shall not be made by children without supervision.

DISPOSAL:Donot dispose this product as unsorted municipal waste. Collection of such waste

separately for special treatment is necessary.

the installation work. Please

carefully read this manual before

unit startup and service.

by dealer or qualied personnel.

Please do not attempt to install the

unit by yourself. Improper handling

may result in water leakage,

electric shock or re disaster etc.

Exclusive accessory

exclusive

Before installation, please check if

the power supply is in accordance

with the requirements specied on

the nameplate. And also take care

of the power safety.

Be sure to use the exclusive

accessory and part to prevent the

water leakage, electric shock and

re accidents.

Wire size of power cord should

be large enough.The damaged

power cord and connection wire

should be replaced by exclusive

cable.

Make sure the unit can be earthed

properly and soundly after

plugging into the socket so as to

avoid electric shock. Please do

not connect the ground wire to gas

pipe, water pipe, lightning rod or

telephone line.

If refrigerant leakage happens

during installation, please ventilate

immediately. Poisonous gas will

emerge if the refrigerant gas meets

re.

After connecting the power cord,

please x the electric box cover

properly in order to avoid accident.

Never fail to comply with the

nitrigen charge requirements.

Charge nitrogen when welding

pipes.

Please rstly connect the wired

controller before energization,

otherwise wired controller can

not be used.

Never short-circiut or cancel the

pressure switch to prevent unit

damage.

Before using the unit, please check

if the piping and wiring are correct

to avoid water leakage, refrigerant

leakage, electric shock, or re etc.

Do not insert fingers or objects

into air outlet/inlet grille.

D.C. Inverter Multi-variable Modular

Open the door and window and

keep good ventilation in the room

to avoid oxygen decit when

the gas/oil supplied heating

equipment is used.

least ve minutes; otherwise it

will inuence oil return of the

compressor.

Do not operate this unit

with wet hands.

Never spray or ush water

towards unit, otherwise

malfunction or electric shock

may happen.

Electrify the unit 8 hours before

operation. Please switch on for

8 hours before operation. Do not

cut off the power when 24 hours

short-time halting (to protect the

compressor).

Volatile liquid, such as diluent

or gas will damage the unit

appearance.Only use soft cloth

with a little neutral detergent to

clean the outer casing of unit.

If anything abnormal happens

(such as burning smell), please

power off the unit and cut off

the main power supply, and

then immerdiately contact Gree

appointed service center.If

abnormality keeps going, the unit

might be damaged and lead to

electric shock or re.

Under cooling mode, please

don't set the room temperature

too low and keep the

temperature difference between

indoor and outdoor unit within

User is not allowed to repair the

unit. Fault service may cause

electric shock or re accidents.

Please contact Gree appointed

Fig.2 is the combination view of the ODU of Modular DC Inverter Multi VRF System and the IDU

of Multi VRF System. IDU can be cassette type, one-way cassette type, wall-mounted type, duct type,

etc. When any one IDU receives operation signal, ODU will start to work according to the capacity;

when all IDUs stop, ODU will also stop.

2.4 The Range of Production Working Temperature

Cooling Ambient temperature: -5 ~52

Heating Ambient temperature: -20 ~24

When the indoor units are all VRF fresh air processor, the unit operating range is as follows:

Cooling Ambient temperature: 16°C~45°C

Heating Ambient temperature: -7°C~16°C

If the temperature is beyond the range, the safety protection measure of the unit may take effect,

and the air conditioning unit will stop.

is against dust, typhoon and

earthquake.

Try to keep the unit away

from combustible,inammable

and corrosive gas or exhaust

gas.

Keep the indoor and outdoor

units close to each other as

much as possible so as to

decrease the pipe length and

bends.

Leave some space for heat

exchanging and servicing so

as to guarantee unit normal

operation.
