1 Sound pressure
Is what the listener (our ears hear). It is the pressure disturbance in the atmosphere, measured using
predened conditions, such as the location of the equipment, environmental conditions, and the distance from
which the sound is measured. Sound pressure level focuses on how loud the noise is at a specic location,
which can vary based on distance and surroundings.
1 Sound power
Measure of acoustic energy at the source. It quanties the overall noise produced. Sound power level is a
measure of how much noise the heat pump generates in total, irrespective of the distance from the source to
the listener.

Install the unit on a wall that can support the unit’s weight. If the chosen location cannot support
the unit’s weight, or the installation is not done properly, the unit may drop and cause serious injury
and damage.
Do not install the unit in a location that may be exposed to combustible gas leaks. If combustible
gas accumulates around the unit, it may cause a re.
For R32 refrigerant models, appliance shall be installed and operated in a room with a oor area
larger than 4 m2.
When choosing a location be aware that there needs to be ample room for a hole for the signal
cable and refrigerant piping that connects the indoor and outdoor units. The default position for all
piping is to the right side of the indoor unit. However the unit can accommodate piping to the left
and right.
Select installation location
Refer notes and clearances diagram on previous page.
Attach mounting plate to wall, refer dimensions on p.42
• Remove the screw that attaches the mounting plate to the back of the indoor unit.
• Secure the mounting plate to the wall with the screws provided. Make sure the mounting
plate is at against the wall.
If the wall is made of brick, concrete, or similar, drill 5 mm diameter holes in the wall and insert
sleeve anchors. Secure the mounting plate to the wall by tightening the screws directly to the
clip anchors.
Drill hole in wall for connective piping
Determine the location of the hole in the wall based on the position of the mounting plate.
Using a 65 mm or 75 mm core drill, drill a hole in the wall. When drilling
make sure to avoid wires, plumbing, and other sensitive components.
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 approximately
5-7 mm. This will ensure the water drains properly.
Place the protective wall cu󰀨 in the hole. This protects the edges of the
hole and will help seal it when the installation is nished.
Prepare refrigerant piping
The refrigerant piping is inside an insulating sleeve which is attached to the back of the unit.
You must prepare the piping before passing it through the hole in the wall.
Based on the position of the hole in the wall relative to the mounting
plate, choose the side from which the piping will exit the unit. If the hole is
behind the unit, keep the knockout panel in place. If the hole is to the side
of the indoor unit, remove the plastic knockout panel from that side of the
unit. This will create a slot through which your piping can exit. Use needle
nose pliers if the plastic panel is too di󰀩cult to remove by hand.
Connect the indoor unit’s refrigerant piping to the connective piping that will join the indoor
and outdoor unit. Be careful not to dent or damage the piping while bending away from the
unit. Any dents in the piping will a󰀨ect the unit’s performance.

Refrigerant piping can exit the indoor unit from four di󰀨erent angles; left-hand side, right-hand side,
left rear, and right rear.
Connect drain hose
The drain hose is attached to the left-hand side of the unit. However, it can also be attached
to the right-hand side. To ensure proper drainage attach the drain hose on the same side that
your refrigerant piping exits the unit. Attach the drain hose extension (purchased separately) to
the end of the drain hose.
Wrap the connection point rmly with Teon tape to ensure a good seal to prevent leaks. For
the portion of drain hose that will remain indoors, wrap it with foam pipe insulation to prevent
condensation.
Remove the air lter and pour a small amount of water into the drain pan
to make sure that water ows from the unit correctly. To prevent unwanted
leaks plug the unused drain hole with the rubber plug provided.
CORRECT
Make sure there are
no kinks or dents in the
drain hose to ensure
proper drainage
INCORRECT
Kinks in the drain hose
will create water traps.
INCORRECT
Kinks in the drain hose
will create water traps.
INCORRECT
Do not place the
end in water or
other containers that
collect water. This
will prevent proper
drainage.
5.
Connect signal and power cables
Before performing any electrical or wiring work, turn o󰀨 the mains power to the system.
All wiring must be performed in accordance with the wiring diagram located on the back
of the indoor unit’s front panel.
The signal cable enables communication between the indoor and outdoor units. You must
choose the right cable size before preparing it for connection. The size of the power supply
cable, signal cable, fuse, and switch is determined by the maximum current of the unit. The
maximum current is indicated on the data plate located on the side panel of the unit.
1. Open the front panel of the indoor unit.
2. Using a screwdriver, open the wire box cover on the right side of the unit, this will reveal
the terminal block.
3. Unscrew the cable clamp below the terminal block and place it to the side.
4. Facing the back of the unit, remove the plastic panel on the bottom left-hand side.

Connect signal and power cables continued
5. Feed the signal wire through the slot, from the back of the unit to the front.
6. Facing the front of the unit, connect the wires according to the wiring diagram, connect the
u-lug and rmly screw each wire to its corresponding
terminal.
7. Make sure every connection is secure, use the cable
clamp to fasten the signal cable to the unit. Screw the
cable clamp down tightly.
8. Replace the wire box cover on the front of the unit, and
the plastic panel on the back.
6.
Wrap piping and cables
Before passing the piping, drain hose, and the signal cable through the wall, bundle them
together to save space, protect and insulate them.
Bundle the drain hose, refrigerant pipes, and signal cable as shown above. Make sure the
drain hose is at the bottom of the bundle. Putting the drain hose at the top can cause the drain
pan to overow, which can lead to re or water damage.
While bundling, DO NOT intertwine or cross the signal cable with any other wiring.
Using adhesive vinyl tape, attach the drain hose to the underside of the refrigerant pipes.
Using insulation tape, wrap the signal wire, refrigerant pipes, and drain hose tightly together.
When wrapping the bundle keep the ends of the piping unwrapped so they can be tested for

1. Check the ends of the refrigerant pipes are sealed to prevent dirt or foreign materials from
entering the pipes.
2. Slowly pass the wrapped bundle of refrigerant pipes, drain hose, and signal wire through
the hole in the wall.
3. Hook the top of the indoor unit on the upper hook of the mounting plate. Check that the
unit is hooked rmly by applying slight pressure to the left and right-hand sides of the unit.
The unit should not move.
4. Using even pressure, push down on the bottom half of the unit. Keep pushing down until
the unit snaps onto the hooks along the bottom of the mounting plate. Check that the unit
is rmly mounted.
If the refrigerant piping is already embedded in the wall do the following:
1. Hook the top of the indoor unit on the upper hook of the mounting plate.
2. Use a bracket or wedge to prop up the unit, giving you enough room to connect the
refrigerant piping, signal cable, and drain hose.
3. Connect drain hose and refrigerant piping, refer previous pages.
4. Keep the pipe connection points exposed to perform the leak test. After the leak test wrap
the connection points with insulation tape.
5. Remove the bracket or wedge that is propping up the unit, and using even pressure, push
down on the bottom half of the unit. Keep pushing down until the unit snaps onto the
hooks along the bottom of the mounting plate.

Mount indoor unit
Before starting ensure the unit is completely aligned with the mounting holes.
1. Install and t pipes (and wires). When choosing where to start, determine the direction of the
pipes to be drawn out. Align the refrigerant pipes, drain pipes, and indoor and outdoor lines
with their connection points before mounting the unit.
2. Install hanging screw bolts. Drill four holes 10 cm deep at the ceiling hook positions in the
internal ceiling. Be sure to hold the drill at a 90° angle to the ceiling. Secure the bolts using the
washers and nuts provided. Install the four suspension bolts.
3. Mount the indoor unit with at least two people to lift and secure it. Insert suspension bolts into
the unit’s hanging holes. Fasten them using the washers and nuts provided.
4. Mount the unit onto the hanging screw bolts with a block. Ensure the unit is level. If not level
leaks could occur.
5. Install the lter(s), and install the canvas tie-in (non-ammable to prevent vibrating) between
the body and the duct. The air inlet and air outlet duct should be far enough apart to avoid an
air passage short-circuit. Connect the duct according to diagram below.
- Do not place the connecting duct weight on the indoor unit.
- Insulation foam must be wrapped outside the duct to avoid condensate.
6. Change the fan motor static pressure according to external duct static pressure, see page 20.

Drainpipe installation
The drainpipe is used to drain water away from the unit. Improper installation may cause unit and
property damage.
• Insulate all piping to prevent condensation which could lead to water damage.
• If the pipe is bent or installed correctly water may leak and cause a water level switch error.
• Ensure the drain hose in placed in an appropriate area to avoid water damage and injury if the
drain water has frozen.
This installation requires polyethylene tube (outside diameter 3.7-3.9 cm, inside diameter 3.2 cm).
1. Install the drainpipe as shown below.
1-1.5 m
Downward slope
1/100
Cover the drainpipe with insulation. Attach the
mouth of the drain hose to the unit’s outlet pipe.
Sheath the mouth of the hose and clip it rmly
with a pipe clasp.

2. Extended drainpipe
When using an extended drainpipe, tighten the
indoor connection with an additional protection
tube to prevent it from pulling loose.
The drainpipe should slope downward at a
gradient of at least 1/100 to prevent water from
owing back into the unit. To prevent sagging
space hanging wires every 1-1.5 m.
If the outlet of the drainpipe is higher than the
body’s pump joint, provide a lift pipe for the
exhaust outlet of the indoor unit. The lift pipe
must be installed no higher than 75 cm from
the ceiling board, and the distance between the
unit and the lift pipe must be less than 30 cm.
Incorrect installation could cause water to ow
back into the unit and ood.

4. Installation continued
Using a 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 approx.
12 mm. This will ensure
proper drainage.
Place the protective wall cu󰀨 in the hole. This
protects the edges of the hole and will help seal
it.
Wall
InsideOutside
Approx. 12 mm

Pass the drain hose through the hole in the wall. Make sure the water drains to a safe location
where it not will cause water damage or create a slipping hazard.
The drainpipe outlet should be at least 5 cm above the ground. If it touches the ground, the unit
may become blocked and malfunction.
If you discharge the water directly into a sewer, make sure that the drain has a U or S pipe to catch
odours that may come back into the house.
5. Drainage test
Check that the drainpipe is unhindered. In new builds this test should be done before lining the
ceiling.
1. Remove the test cap and pour two litres of water into the condensate pan.
2. Operate the unit in COOLING mode. Conrm the condensate pump turns on and begins to
remove the two litres of water. This should take approximately one minute. Check for leaks
during this time.
3. Power o󰀨 the unit and replace the cap.
