INSTALLATION INSTRUCTIONS

Selecting installation place

Read completely, then follow step by step.

Indoor unit:

Do not expose the indoor unit to heat or steam.

Select a place where there are no obstacles

in front or around the unit.

Make sure that condensation drainage can

be conveniently routed away.

Do not install near a doorway.

Ensure that the space on the left and right

of the unit is more than 12cm/4.72in.

Use a stud finder to locate studs to prevent unnecessary damage to the wall.

The indoor unit should be installed on the wall at a height of 2.3m/7.55ft or more from the floor.

The indoor unit should be installed allowing a minimum clearance of 15cm/5.9in from the ceiling.

Any variations in pipe length will/may require adjustment to refrigerant charge.

There should not be any direct sunlight. Otherwise, the sun will fade the plastic cabinet and

affect its appearance. If unavoidable, sunlight prevention should be taken into consideration.

Outdoor unit:

If an awning is built over the outdoor unit to

prevent direct sunlight or rain exposure,

make sure that heat radiation from the

condenser is not restricted.

Ensure that the clearance around the back

of the unit is more than 30cm/11.81in and left

side is more than 30cm/11.81in. The front of the

unit should have more than 200cm/78.74in of

clearance and the connection side (right side)

should have more than 60cm/23.62in of clearance.

Do not place animals and plants in the path of the air inlet or outlet.

Take the air conditioner weight into account and select a place where noise and vibration

will not be an issue.

Select a place so that the warm air and noise from the air conditioner do not disturb neighbors.

If the outdoor unit is installed on a roof structure, make sure unit is level.

Ensure the roof structure and anchoring method are adequate for the unit location.

Consult local codes regarding rooftop mounting.

If the outdoor unit is installed on roof structures or external walls, this may result in excessive

noise and vibration, and may also be classed as a non serviceable installation.

Rooftop installation:

After completing steps 1- 4, check that all the

connections are sealed correctly using leak

detection spray or soap suds. If any bubbles form,

the system has a leak and the screw connectors

must be retightened using an open-ended wrench.

5. Now remove the cover on the top valve using a

19 mm open-ended wrench. Open the valve by

turning it counter-clockwise as far as it will go

using a 5 mm Allen key. The valve is now open. If

the valve is not opened fully, the system may

malfunction and suffer damage. Screw the cover

back on to the top valve and tighten it well to

ensure that it is properly sealed. See Fig.24.

6. Now remove the cover on the bottom valve using

a 19 mm open-ended wrench. Open the valve by

turning it counter-clockwise as far as it will go

using a 5 mm Allen key. The valve is now open.

If the valve is not opened fully, the system may

malfunction and suffer damage. Screw the cover

back on to the bottom valve and tighten it well to

ensure that it is properly sealed. See Fig.25.

7. After completing steps 1-6, check that all the

connections are sealed correctly using leak

detection spray or soap suds. If any bubbles form,

the system has a leak and the screw connectors

must be retightened using an open- ended spanner.

8. Start the equipment so that the operating

pressures build up inside it. Check all the

connectors again for signs of leaks

a) during cooling mode

b) in heating mode.

If any bubbles form, the system has a leak and the

screw connectors must be retightened using an

open-ended wrench. I

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 63 °F), the unit cannot be controlled by

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

operation is used when the remote controller is disabled or maintenance is 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 30 minutes.
