Suggested installation positions: (AC=air conditioner)
Not recommended installation positions: (AC=air conditioner)
Effective Detection range of intelligent eye:
-- cover a level angle of 140 degrees, a fan-shaped area with a radius of 4 meters;
-- the detection radius is determined by the air conditioner installation position. It is recommended to
install the unit at 220mm~250mm from the floor.
-- The lower the unit installs, the smaller distance the Intelligent Eye detects.
The following situations may affect the detection result of the Intelligent Eye:
-- size of the room, thickness of the mosquito net, position of bed, double layer bed.
-- the children is less than one meter high.
-- obstacles between Intelligent Eye and bed.
-- a heating appliance in the conditioned space.

7.2 Connecting the cables
The power cord of connect should be selected according to the following specifications sheet.
Rated current of appliance Nominal cross-sectional area (mm²)
>3 and ≤6 0.75
>6 and ≤10 1
>10 and ≤16 1.5
>16 and ≤25 2.5
The cable size and the current of the fuse or switch are determined by the maximum current indicated
on the nameplate which located on the side panel of the unit. Please refer to the nameplate before
selecting the cable, fuse and switch.

7.4 Installation for the first time
Air and moisture in the refrigerant system have undesirable effects as below:
● Pressure in the system rises.
● Operating current rises.
● Cooling or heating efficiency drops.
● Moisture in the refrigerant circuit may freeze and block capillary tubing.
● Water may lead to corrosion of parts in the refrigerant system.
Therefore, the indoor units and the pipes between indoor and outdoor units must be leak tested
and evacuated to remove gas and moisture from the system.
Gas leak check (Soap water method):
Apply soap water or a liquid neutral detergent on the indoor unit connections or outdoor unit
connections by a soft brush to check for leakage of the connecting points of the piping. If bubbles
come out, the pipes have leakage.
1. Air purging with vacuum pump
1) Completely tighten the flare nuts of the indoor and outdoor units, confirm that both the 2-way and
3-way valves are set to the closed position.
2) Connect the charge hose with the push pin of handle lo to the 3-way valves gas service port.
3) Connect the charge hose of handle hi connection to the vacuum pump.
4) Fully open the handle Lo of the manifold valve.
5) Operate the vacuum pump to evacuate.
6) Make evacuation for 30 minutes and check whether the compound meter indicates -0.1Mpa. If the
meter does not indicate -0.1Mpa after pumping 30 minutes, it should be pumped 20 minutes more.
If the pressure can’t achieve -0.1Mpa after pumping 50 minutes, please check if there are some
leakage points.
Fully close the handle Lo valve of the manifold valve and stop the operation of the vacuum pump.
Confirm that the gauge needle does not move (approximately 5 minutes after turning off the vacuum
pump).
7) Turn the flare nut of the 3-way valves about 45° counterclockwise for 6 or 7seconds after the gas
coming out, then tighten the flare nut again. Make sure the pressure display in the pressure
indicator is a little higher than the atmosphere pressure. Then remove the charge hose from the 3
way valve.
