requirements, such as kitchen. Otherwise, it will affect the normal operation or shorten the service life of the unit, or

even cause fire hazard or serious injury. As for above special places, please adopt special air conditioner with

anti-corrosive or anti-explosion function.

(2) Follow this instruction to complete the installation work. Please carefully read this manual before unit startup and

service.

(3) Wire size of power cord should be large enough. The damaged power cord and connection wire should be replaced

by exclusive cable.

(4) After connecting the power cord, please fix the electric box cover properly in order to avoid accident.

(5) Never fail to comply with the nitrigen charge requirements. Charge nitrogen when welding pipes.

(6) Never short-circiut or cancel the pressure switch to prevent unit damage.

(7) Please firstly connect the wired controller before energization, otherwise wired controller cannot be used.

(8) Before using the unit, please check if the piping and wiring are correct to avoid water leakage, refrigerant leakage,

electric shock, or fire etc..

(9) Do not insert fingers or objects into air outlet/inlet grille.

(10) Open the door and window and keep good ventilation in the room to avoid oxygen deficit when the gas/oil supplied

heating equipment is used.

(11) Never start up or shut off the air conditioner by means of directly plug or unplug the power cord.

(12) Turn off the unit after it runs at least five minutes; otherwise it will influence oil return of the compressor.

(22) Be sure to use the exclusive accessory and part to prevent the water leakage, electric shock and fire accidents.

(23) 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.

(24) 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).

(25) If refrigerant leakage happens during installation, please ventilate immediately. Poisonous gas will emerge if the

refrigerant gas meets fire.

(26) 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.

(27

) If anything abnormal happens (such as burning smell), please power off the unit and cut off the main power supply,

and then immediately contact Gree appointed service center. If abnormality keeps going, the unit might be damaged

and lead to electric shock or fire.

Fig.2 is the combination view of the ODU of Ultra Heat GMV Multi VRF Modular 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 operation Ambient temperature: -10ºC(14ºF)~52ºC(125.6ºF)

Heating operation Ambient temperature: -30ºC(-22ºF)~24ºC(75.2ºF)

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

Cooling operation Ambient temperature: 16ºC(60.8ºF)~45ºC(113ºF)

Heating operation Ambient temperature: -7ºC(19.4ºF)~16ºC(60.8ºF)

3.2 Installation Site

WARNING

Install the unit at a place where is adequate to withstand the weight of the unit and make sure the unit would not shake

or fall off.

Never expose the unit under direct sunshine and rainfall. Install the unit at a place where is against dust, typhoon and

earthquake.

Try to keep the unit away from combustible, inflammable and corrosive gas or exhaust gas.

Leave some space for heat exchanging and servicing so as to guarantee unit normal operation.

Keep the indoor and outdoor units close to each other as much as possible so as to decrease the pipe length and

bends.

Never allow children to approach to the unit and take measures to prevent children touching the unit.

3.2.1 Space requirement for the surround of outdoor unit

1) Space dimension for single-module unit

Fig.3

2) Space dimension for dual-module unit

Fig.4

3.2.2 Space requirement for the top of outdoor unit

When there is wall (or similar obstruction) above the unit, keep the distance between the unit top and

the wall at least 3000mm (118-1/8in.) or above. When the unit is located in a totally open space with no

obstructions in four directions, keep the distance between the unit top and wall at least 1500mm (59in.)

or above. When space is limited within 1500mm (59in.) or the unit is not set in an open space, air outlet

pipe is required to be installed in order to keep good ventilation.
