Please read these safety precautions carefully before undertaking installation
Please be sure to follow the precautions as listed below, they are important for ensuring your safety.
This symbol indicates the possibilityof death or serious injury.
This symbol indicates the possibilityof injury or damage to property.
1) This equipment must be properly earthed and installed with a circuit breaker. Electrical shock may
result if earthing is inadequate.
2) Do not install the unit in areas where leakage of flammable gases may occur. If gas leaks are allowed
to accumulate around the unit, it may cause fire.
3) Install condensate drain piping as described in the installation instructions. If drainage is insufficient
water may leak into the room and damage furniture and fixtures.
1) Install strictly inaccordance with these installation instructions. If installation is defective or incomplete,
it maycause refrigerant or water leaks, electrical shockor fire.
2) Use the supplied accessories and specified partsfor installation, otherwise it maycause the unit to fall,
leak water, electrical shock or fire.
3) Install in a strong firm location,sufficient to withstand the unitsoperating weight. If the mounting is
insufficient or incomplete, the unit may fall and cause damage and/or injury.
4) Electrical installation must follow all local state and national wiring standards and regulations. A
separate and independent electrical circuit and single outlet must be used. If electrical circuit capacity
is insufficient or electrical connections are defective, it may cause electrical shock or fire.
5) Use the specified cable and ensure connectionsare tight. Clamp the cable so that no external forces
can be placed on the terminals. If connection is inadequate, it may cause overheating and failure.
6) Wiring routing must be properlyarranged so that the control board cover is fixed properly.If thecover
is not fixed properly, it may cause overheating at the connection point and fire or electrical shock.
7) When carrying out refrigerant pipe connections, ensure that no air or other contaminants can enter
the refrigeration circuit. Otherwise, it may cause performance issues, abnormally high pressures
in the refrigeration cycle, possible explosion and/or personal injury.
8) Do notmodify the length of the power supply cord or use an extension cord. Do not share the
electrical outlet with other electrical appliances. Otherwise, it may cause fire or electrical shock.

Electrical safety considerations prior to initial Installation
1. If there is a serious safety issue regarding the power supply, the installer should stop the installation of
the unit, fully explain the situation to the client and delay installation until the issue is resolved.
2. Power supply voltage should be in the range of 90% - 110% of the rated voltage.
3. Acircuit breaker and mains power switch 1.5 times capacity of the maximum current of the unit shall be
installed in the power circuit.
4. Ensure the air conditioner is earthed correctly.
5. Wire the unit in accordance with the attached Electrical Connection Diagramlocated on the inside of the
panel of the outdoor unit.
6. All wiring must comply with all relevant local and national electrical codes and shall be installed only by
suitably qualified and skilled electricians.
7. An all-pole disconnection device which has at least 3mm separation distance in all poles and circuit
breaker shall be incorporated in the fixed wiring according to the local and national wiring standards.
8. A separate dedicated circuit and single power outlet mustbe used for this system.

Install the outdoor unit on a firm rigid base to prevent excess noise and vibration.
Set the direction of the unit to ensure optimal condenser air circulation.
If there is risk of exposure to strong prevailing winds such as in coastal applications, ensure
that the unit is placed at 90 degrees to the wind direction, or provide protection from the wind
by the use of shields.
In particularly windy applications, install the unit to prevent adverse interaction with the unit.
If mounting on a wall or structure, the installation bracket should be adequately sized to support
the unit fully. The installation wall should be solid brick, concrete or similar construction, or
action must be taken to reinforce and/or support the unit.
The connection between bracket, wall and unit should be firm, stable and reliable.
Make sure that no obstacles restrict the condenser air flow or block any heat radiation.

The condensate drain joints differ slightly according to the
different size outdoor units in the range.
For the condensate drain joint with a 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 joint 90 degrees to secure.
To install drain joint as shown in Fig.B, insert the condensate
drain joint into the base pan hole of outdoor unit until it clicks
in place. Connect the condensate drain joint with a drain hose
(provided by installer) to facilitate drainage of water produced
by the outdoor unit during heating mode.

1. Completely tighten the flare nuts, A, B, C and D, and
attach the manifold valve charge hose to a charge port
of the valve on the gas pipe side.
2. Then connect the charge hose to the vacuum pump.
3. Fully open the Low tap of the manifold valve.
4. Switch on the vacuum pump to evacuate the system.
After starting the pump, slightly loosen the flare nut of
the gas side valve, and check that air is entering.
(Operation noise of the vacuum pump changes and
the compound gauge indicates 0 instead of minus).
Re-tighten the flare nut and evacuate the system.
5. After the evacuation is complete, fully close the Low
tap of the manifold valve and switch off the vacuum
pump.
Evacuate for 15 minutes or more and check that
the compound gauge indicates -76cmHg (-1.0x10 Pa).

tighten the stem of the liquid line. Make sure that the
pressure displayed on the pressure gauge is slightly
higher than atmospheric pressure.

remote control to run in cooling mode, but manual operation can be employed. Manual operation
should only be used when the remote control is disabled or maintenance is necessary.
Hold the indoor unit front panel sides and lift up at an angle until the panels clicks and remains open.
Press the Manual control button to select theAUTO or COOL, the unit will now operate under Forced
AUTO or COOL mode (see User Manual for details).

Connect the indoor unit first, then the
outdoor unit.
Do not allow the piping to be dislodged from the
back of the indoor unit.
Ensure that the condensate drain has a constant
fall to the outlet.
Insulate any condensate drain extensions.
Be sure that the drain hose is located at
the lowest part of the piping bundle. Locating it
on the upper side can cause drain tray to
overflow inside the unit.
Ensure that power wiring is routed separately
to any other wiring.
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 left and right to check.
3. Positioning adjustment can be easily made by
propping the indoor unit with a cushioning material
between the indoor unit and the wall. Make sure
this is removed at completion.
4. Press the lower left and right hand sides of the
unit firmly against the installation plate until the
hooks engage with the relevant mounting slots.
CAUTION

1. For left-hand or right-hand piping,
remove the pipe cover from the side panel.
2. For right rear and left rear pipe exits,
install the piping as shown.
NOTE: When choosing the condensate
drain connection side, please enure that the
condensate drain connection on the other
side (if applicable) is plugged. The condensate
drain shall be installed by a qualified installer. Right rear pipe exit
3. Bundle the pipes, connecting cables, and
condensate drain securely with tape, as
shown in Figure on the right.
