Connective pipe installation

1. For the left-hand and right-hand piping,

remove the pipe cover from the side panel.

2. For the right back and left back piping,

install the piping as shown.

NOTE:

Both sides drainage structure is

standard. For both sides drainage structure,

it can be choosen for right, left or both sides

drainage connection. If choosing both sides

drainage connection, another proper drain

hose is needed as there is only one drain

hose offered by factory. If choosing one side

drainage connection, make sure the drain

hole on the other side is well plugged.

For 9k/12k models, if choosing left-hand

or left-back piping,please choosing left side

drainage connection. The connection of the

drain hose is supposed to be done by

qualified installer in case of water leakage.

3. Bundle the tubing, connecting cable, and

drain hose with tape securely, evenly as

shown in Figure on the right.

Because the condensed water from rear

of the indoor unit is gathered in ponding

box and is piped out of room. Do not put

anything else in the box.

CAUTION

Connect the indoor unit first, then the

outdoor unit.

Do not allow the piping to let out from the

back of the indoor unit.

Be careful not to let the drain hose slack.

Heat insulation should be done to the

extension drain hose of indoor unit.

Be sure that the drain hose is located at

the lowest side of the bundle. Locating at

the upper side can cause drain pan to

overflow inside the unit.

Never intercross nor intertwist the power

wire with any other wiring.

Indoor unit installation

1. Pass the piping through the hole in the wall.

2. Hook the indoor unit onto the upper portion

of installation plate(Engage the indoor unit with

the upper edge of the installation plate). Ensure

the hooks are properly seated on the installation

plate by moving it in left and right.

3. Piping can easily be made by lifting the indoor

unit with a cushioning material between the

indoor unit and the wall. Get it out after finish

piping.

4. Press the lower left and right side of the unit

against the installation plate until hooks

engages with the their slots.

OUTDOOR INSALLATION PRECAUTION

Install the outdoor unit on a rigid base to prevent increasing noise level and vibration.

Determine the air outlet direction where the discharged air is not blocked.

In the case that the installation place is exposed to strong wind such as a seaside, make

sure the fan operating properly by putting the unit lengthwise along the wall or using a dust

or shield plates.

Specially in windy area, install the unit to prevent the admission of wind. If need suspending

installation, the installation bracket should accord with technique requirement in the

installation bracket diagram. The installation wall should be solid brick, concrete or the same

intensity construction, or actions to reinforce, damping supporting should be taken.

The connection between bracket and wall, bracket and the air conditioner should be firm,

stable and reliable.

Be sure there is no obstacle which block radiating air.

DRAIN JOINT INSTALLATION

NOTE:

The drain joint is slightly different according to the

different outdoor unit.

For the drain joint with the seal(Fig.A), first fit the seal onto

the drain joint, then insert the drain joint into the base pan

。

hole of outdoor unit, rotate 90 to securely assemble them.

To install drain joint as shown in Fig.B, insert the drain

joint into the base pan hole of outdoor unit until it remains

fixed with a clicking sound. Connecting the drain joint with

an extension drain hose (Locally purchased), in case of the

water draining off the outdoor unit during the heating mode.

REFRIGERANT PIPE CONNECTION

Flaring

1. Cut a pipe with a pipe cutter.

2. Put flare nuts on pipe/tube having

completed burr removal and flare the pipe.

3. Firmly hold copper pipe in a die in the

dimension shown in the table below.

CONNECT THE CABLE TO THE OUTDOOR UNIT

1. Remove the electrical control board cover from the outdoor unit by loosening the screw.

2. Connect the connective cables to the terminals as identified with their respective matched numbers

on the terminal block of indoor and outdoor units.

3. Secure the cable onto the control board with the cord clamp.

4. To prevent the ingress of water, form a loop of the connective cable as illustrated in the installation

diagram of indoor and outdoor units.

5. Insulate unused cords (conductors) with PVC-tape. Process them so they do not touch any electrical

or metal parts.

AIR PURGING AND TEST OPERATION

Connective pipe length will affect the capacity and energy efficiency of the unit. The

NOTE:

nominal efficiency is tested basing on the pipe length of 5 meters.

1. Air purging

The indoor unit and tubing between the indoor and outdoor unit must be leak tested and evacuated

to remove any noncondensables and moisture from the system.

Check that each tube(both liquid and gas side tubes) between the indoor and outdoor units have

been properly connected and all wiring for the test run has been completed.

Pipe length and refrigerant amount:

Connective pipe length

Air purging method

Less than 5m

Use vacuum pump

More than 5m

R410A: (Pipe length-5)x20g/m

For the R410A refrigerant model, make sure the refrigerant added into air conditioner is liquid

form in any cases.

When relocating the unit to another place, using vacuum pump to perform evacuation.

CAUTION

Open the valve stem until it hits against

the stopper. Do not try to open it further.

Securely tighten the valve stem cap with

a spanner or the like.

Valve stem cap tightening torque. See

Tightening torque table.

2. When using the Vacuum Pump

1. Completely tighten the flare nuts, A, B, C, D, connect

the manifold valve charge hose to a charge port of the

packed valve on the gas pipe side.

2. Connect the charge hose connection to the vacuum

pump.

3. Fully open the handle Lo of the manifold valve.

4. Operate the vacuum pump to evacuate. After starting

evacuation, slightly loose the flare nut of the packed

valve on the gas pipe side and check that the air is

entering. (Operation noise of the vacuum pump changes

and a compound meter indicates 0 instead of minus)

5. After the evacuation is complete, fully close the handle

Lo of the manifold valve and stop the operation of the

vacuum pump.

Make evacuation for 15 minutes and more and check

that the compound meter indicates -76cmHg(-1.0x10 Pa).

6. Turn the stem of the packed valve B about 45 counter-

clockwise for 6~7 seconds 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.

7. Remove the charge hose from the Low pressure charge hose.

8. Fully open the packed valve stems B and A.

9. Securely tighten the cap of the packed valve.

3. Safety and leakage check

1. Soap water method:

Apply a soap water or a liquid neutral detergent on the indoor

unit connections and outdoor unit connections by a soft brush

to check for leakage of the connecting points of the piping. If

bubbles come out, it indicates that the pipes have leakage.

2. Leak detector

Use the leak detector to check for leakage.

CAUTION

A: Lo packed valve B: Hi packed valve

C and D are ends of indoor unit connection.

4. Test running

Perform test operation after completing gas leak check at the flare nut connections and electrical

safety check.

Check that all tubing and wiring have been properly connected.

Check that the gas and liquid side service valves are fully open.

1. Connect the power, press the ON/OFF button on the remote controller to turn the unit on.

2. Use the MODE button to select COOL, HEAT, AUTO and FAN to check if all the functions works

well.

3. When the ambient temperature is too low(lower than 17 C), the unit cannot be controlled by the

remote controller to run at cooling mode, manual operation can be taken. Manual operation is

used only when the remote controller is disable or maintenance necessary.

Hold the panel sides and lift the panel up to an angle until it remains fixed with a clicking sound.

Press the Manual control button to select the AUTO or COOL, the unit will operate under Forced

AUTO or COOL mode(see User Manual for details).

4. The test operation should last about 30 minutes.
