can cause electrical components to short circuit.
1. The product must be properly earthed at the time of installation, or electrical shock may occur.
2. Install drainage piping according to the instructions in this manual. Improper drainage may cause water damage to
your home and property.
SAFETY INSTRUCTIONS
1. Prevailing WH&S regulations must be observed and will take precedence to the safety instructions contained on
this manual. Safe work practices and environment must be the paramount importance in the performance of all the
service procedures.
2. Ensure that unit installation complies with relevant council regulations and building code standards.
3. All electrical wiring must be in accordance with current electrical authority regulations and all wiring connections to
be as per electrical diagram provided.
4. Always wear appropriate PPE, remove any dangling jewellery and protect long hair by wearing a cap.
5. Make sure that safety guards and panel covers are always firmly secured and not damaged.
6. This appliance is not intended for use by young children or infirm persons unless they have been adequately

8. Secure the power cords and control cables that goes in/out the unit. Use the cable ties provided in the control box.
WARNING
1. Carefully read all the Safety Precautions before installation.
2. In certain functional environments, such as kitchens, server rooms, etc., the use of specially designed
air-conditioning units is highly recommended.
3. Only qualified HVAC technicians* should install, repair and service this air conditioning unit. Improper service or
alteration by unqualified technician could result in significant and major damage to the product or property which
may render your warranty null and void. Such unqualified service could also lead to severe physical injury or death.
Follow all safety instructions in this literature and all warning labels that are attached to the equipment.
4. During installation, ensure there are no refrigerant leaks. Refrigerant is toxic and poses a serious health and safety risk.

Installation Instructions – Indoor Unit
PRIOR TO INSTALLATION
Before installing the indoor unit, refer to the label on the
product box to make sure that the model number of the
indoor unit matches the model number of the outdoor
unit.
Step 1: Select installation location
Before installing the indoor unit, you must choose an
appropriate location. The following are standards that will
help you choose an appropriate location for the unit.
Proper installation locations meet the following
standards:
þGood air circulation
þConvenient drainage
þNoise from the unit will not disturb other people
þFirm and solid—the location will not vibrate
þStrong enough to support the weight of the unit
þA location at least one metre from all other electrical
devices (e.g., TV, radio, computer)
DO NOT install unit in the following locations:
Near any source of heat, steam, or combustible gas
Near flammable items such as curtains or clothing
Near any obstacle that might block air circulation
Near the doorway
In a location subject to direct sunlight
NOTE ABOUT WALL HOLE:
If there is no fixed refrigerant piping:
While choosing a location, be aware that you should
leave ample room for a wall hole (see Drill wall hole
for connective piping step) for the signal cable and
refrigerant piping that connect the indoor and outdoor
units. The default position for all piping is the right side of
the indoor unit (while facing the unit). However, the unit
can accommodate piping to both the left and right.
Refer to the following diagram to ensure proper
distance from walls and ceiling:

Step 2: Attach mounting plate to wall
The mounting plate is the device on which you will mount
the indoor unit.
1. Remove the screw that attaches the mounting plate to
the back of the indoor unit.
2. Place the mounting plate against the wall in a location
that meets the standards in the Select Installation
Location step. (See Mounting Plate Dimensions for
detailed information on mounting plate sizes.)
3. Drill holes for mounting screws in places that:
•have studs and can support the weight of the unit
•correspond to screw holes in the mounting plate
4. Secure the mounting plate to the wall with the screws
provided.
5. Make sure that mounting plate is at against the wall.
NOTE FOR CONCRETE OR BRICK WALLS:
If the wall is made of brick, concrete, or similar material,
drill 5mm-diameter holes in the wall and insert the sleeve
anchors provided. Then secure the mounting plate to
the wall by tightening the screws directly into the clip
anchors.
Correct orientation of Mounting Plate
Step 3: Drill wall hole for connective piping
You must drill a hole in the wall for refrigerant piping, the
drainage pipe, and the signal cable that will connect the indoor
and outdoor units.
1. Determine the location of the wall hole based on the position
of the mounting plate. Refer to Mounting Plate
Dimensions on the next page to help you determine the
optimal position. The wall hole should have a 65mm
diameter at least, and at a slightly lower angle to facilitate
drainage.
2. Using a 65-mm core drill, drill a hole in the wall. Make
sure that the hole is drilled at a slight downward angle, so
that the outdoor end of the hole is lower than the indoor end
by about 5mm to 7mm. This will ensure proper
water drainage. (See Fig. 5.3)
3. Place the protective wall cuff in the hole. This protects the
edges of the hole and will help seal it when you finish the
installation process.
CAUTION
When drilling the wall hole, make sure to avoid wires,
plumbing, and other sensitive components.
