Indoor unit

When connecting the cable after installing the indoor unit

1. Insert from outside the room cable into left side of the wall hole, in which

the pipe has already existed.

2. Pull out the cable on the front side, and connect the cable making a loop.

When connecting the cable before installing the indoor unit

Insert the cable from the back side of the unit, then pull it out on the front side.

Loosen the screws and insert the cable ends fully into terminal block, then tighten the screws.

Pull the cable slightly to make sure the cables have been properly inserted and tightened.

After the cable connection, never fail to fasten the connected cable with the wiring cover.

Note: When connecting the cable, confirm the terminal number of indoor and outdoor units carefully. If wiring

is not correct, proper operation can not be carried out and will cause defect.

1. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar

qualified person. The type of connecting wire is

2. If the fuse on PC board is broken please change it with the type of T. 3.15A/250V.

3. The wiring method should be in line with the local wiring standard.

4. After installation, the power plug should be easily reached.

5. A breaker should be incorporated into fixed wiring. The breaker should be all-pole switch and the

distance between its two contacts should be not less than 3mm.

2.Connection of pipes

Install according to

To bend a pipe, give the roundness as large as possible not to crush the pipe ,and the bending radius

should be 30 to 40 mm or longer.

Connecting the pipe of gas side first makes working easier.

The connection pipe is specialized for R410A.

Be careful that matters, such as wastes of sands, etc. shall not enter the pipe.

The standard pipe length is 10m. If it is over 20m, the function of the unit will be affected. If the pipe has

to be lengthened, the refrigerant should be charged, according to 20 g/m. But the charge of refrigerant

must be conducted by professional air conditioner engineer. Before adding additional refrigerant,

perform air purging from the refrigerant pipes and indoor unit using a vacuum pump,then charge

additional refrigerant.

Use the same method on indoor unit. Loosen the screws on terminal block and insert the plugs fully into

terminal block, then tighten the screws.

If wiring is not correct, proper operation can not be carried out and controller may be damaged.

If the drain-elbow is used, please attach it as

figure. (Note: Only for heat pump unit.)

Drawing for the installation of indoor and outdoor units

Insert the cable according to terminal number in the same manner as the indoor unit.

Fix the cable with a clamp.

5.Purging Method:To use vacuum pump

Detach the service port's cap of 3-way valve, the

valve rod's cap for 2-way valve and 3-way's, connect

the service port into the projection of charge hose

(Iow) for gaugemanifold.Then connect the projection

of charge hose (center) for gaugemanifold into

vacuum pump.

Open the handle at Iow in gaugemanifold, operate

vacuum pump. If the scale-moves of gause (Iow)

reach vacuum condition in a moment, check again.

Vacuumize for over 15min.And check the level gauge

which should read -0.1 MPa (-76 cm Hg) at Iow

pressure side.After the completion of vacuumizing,

close the handle 'Lo' in gaugemanifold and stop the

operation of the vacuum pump.

Check the condition of the scale and hold it for 1-2min.

If the scale-moves back in spite of tightening, make

flaring work again, the return to the beginning of .

Open the valve rod for the 2-way valve to an angle of

anticlockwise 90 degrees.

After 6 seconds, close the 2-way valve and make

the inspection of gas leakage.

No gas leakage?

In case of gas leakage, tighten

parts of pipe connection.If

leakage stops, then proceed

steps.

Detach the charge hose from the service port, open

2-way valve and 3-way.Turn the valve rod anticlockwise

until hitting lightly.

To prevent the gas leakage, turn the service port's

cap, the valve rod's cap for 2-way valve and 3-way's

a little more than the point where the torque increases

suddenly.

After attaching the each caps, check the gas leakage

around the caps.

CAUTION:

1.If the refrigerant of the air conditioner leaks, it is necessary to

discharge all the refrigerant.Vacuumize first, then charge the liquid

refrigerant into air conditioner according to the amount marked on

the name plate.

2.Please do not let other cooling medium, except specified one (R410A),

or air enter into the cooling circulation system. Otherwise, there will be

abnormal high pressure in the system to make it crack and lead to

personal injuries.

If it does not stop gas leakage, discharge

whole refrigerants from the service port.

After flaring work again and vacuumize,

fill up prescribed refrigerant from the gas

cylinder.

The power source must be exclusively used for air conditioner. (Over I0A)

In the case of installing an air conditioner in a moist place, please install an

earth leakage breaker.

For installation in other places, use a circuit breaker as far as possible.

Pipe cutting is carried out with a pipe cutter and burs must be removed.

After inserting the flare nut, flaring work is carried out.

Please install the drain hose so as to be downward slope without fail.

Please don't do the drainage as shown below.

Please pour water in the drain pan of the indoor unit, and confirm that drainage is

carried out surely to outdoor.

In case that the attached drain hose is in a room, please apply heat insulation

to it without fail.

Please kindly explain to our customers how to operate through the instruction manual.
