It is advisable to avoid more than 2 blockage
directions. For better ventilation & multiple-outdoor
installation, please consult authorized dealer/specialist.

11.1 Indoor Unit
11.1.1 Selecting the Installation Location
Take into consideration the following contents when creating the blueprint.
Ŷ
Indoor unit installation location
x Do not install the unit in excessive oil fume area such as kitchen, workshop and etc.
x The location should be strong enough to support the main unit without vibration.
x There should not be any heat or steam source nearby.
x Drainage should be easy. Avoid locating the drain port close to ditches (domestic wastewater).
x Avoid locations above entrances and exits.
x Do not block the air intake and discharge passages.
x Select the location that enables the cool and warm air to spread out to the entire room.
x Locate the indoor unit at least 3.28 ft (1 m) or more away from a TV, radio, wireless appliance, antenna cable and
fluorescent light, and 6.56 ft (2 m) or more away from a telephone.
x Recommended installation height for indoor unit shall be at least 8.27 ft (2.5 m) from floor.
11.1.2 To Drill a Hole in the Wall and Install a Sleeve of Piping
1 Insert the piping sleeve to the hole.
2 Fix the bushing to the sleeve.
3 Cut the sleeve until it extrudes about 19/32"
(15 mm) from the wall.
When the wall is hollow, be sure to use the sleeve for tube
assembly to prevent pests from damaging the cables, e.g.
mice biting the connection cable.
4 Finish by sealing the sleeve with putty or
caulking compound at the final stage.

11.1.3 Installing the Indoor Unit (Installation Embedded in the Ceiling)
11.1.3.1 Preparation Before Installation
x Always provide sufficient entry and exit space to allow installation work, inspection and unit replacement.
x Waterproof the rear surface of the ceiling below the unit in consideration of water droplets forming and dropping.
When cooling operation is performed for an extended period under the following conditions, water droplets may form and drop. Attach locally
purchased insulation (foamed polyethylene with a thickness of 7/32" (5 mm) or more) to the outside of the indoor unit before installing into the
ceiling to improve heat insulation.
x Locations with a dew point inside the ceiling of 73.4°F (23°C) or more
x Kitchens and other locations that produce large amounts of heat and steam
x Locations where the inside of the ceiling serves as an outside air intake passage
x When installing into a ceiling, select the unit position and airflow direction that enable the cool and warm
air to spread out to the whole room.
x Do not place objects that might obstruct the airflow within 3.28 ft (1 m) below the intake grill.

11.1.4 Connecting the Drain Piping
x Lay the drain piping so as to ensure drainage.
x Use a locally purchased VP20 general rigid PVC pipe (outer diameter ø1 1/32" (ø26)) for the drain piping and
firmly connect the indoor unit and the drain piping using supplied hose band to ensure that no leakage
occurs.
x Drain piping located indoor should always be insulated by wrapping with locally purchased insulation (foamed
polyethylene with a thickness of 13/32" (10 mm) or more).
x The drain piping should have a downward gradient (1/100 or more) and should be secured by using pipe hanging
equipment to avoid creating hills or traps partway.
x Should there be any obstacle preventing the drain piping from being extended smoothly, the drain piping can be
raised outside of the main unit as shown in the illustration below.
Rise
Hill
Unit drain port
Hose band
#
Hard PVC pipe (VP20)
Do not use adhesive.
x Strictly do not install and extend the drain piping from the main unit drain water outlet horizontally or upward or raised it 19 11/16" (500 mm)
or more.
Doing so may result in poor drainage or drain motor failure.
x Do not use drain hose bent at 90° angle. (The maximum permissible bend is 45°.)

11.1.6 Connect the Cable to the Indoor Unit
x Remove control box cover.
x Remove the plugs.
x Fix the conduit connections to the knockout holes
together with lock nuts, then secure them against
the control box side panel.
x Receiver cable wires 8 must pass through the
upper conduit hole.
Make sure the receiver cable is inserted from
inside of the control box.
Connect receiver cable connector to control box
wire connector and fix it to the power supply cord
holder as shown in the diagram.
Insert firmly the connector of receiver cable 8 to
connector at control box of indoor unit.
x Connection cable between indoor unit and
outdoor unit should be UL listed or CSA approved
4 conductor wires minimum AWG16 in
accordance with local electric codes.
o Ensure that the terminal numbers on the
indoor unit are connected to the same
terminal numbers on the outdoor unit by the
right coloured wires as shown in the diagram.
o Earth lead wire should be longer than the
other lead wires as shown in the diagram for
electrical safety purpose in case the cord slips
out from the anchorage.
o Secure the cable onto the control board with
the holder (clamper).

Switching the High State Switch (SW2)
x To increase the air volume, open the control box and on the control board, switch the FAN switch (SW2) to “HI”.
x See the diagram for “Connecting the Indoor/Outdoor Connection Cable”.
Note: Enabling Long-range Remote Control
x To maintain EMC emission limits, cabling interconnecting the HA terminal and subsequent opto-coupler, must be
no more than 6.2 ft (1.9 m) length.
x Loop four turns of this cable through a suitable small EMC ferrite toroid, and protect with a short length of large
diameter heat-shrink tube.
x There is no similar length limit for cable following on from the opto-coupler isolation.
CHECK THE DRAINAGE
Check after connecting the power supply.
x Pour approximately 600 cc of water into the drain
pan of the main unit using a squeeze bottle, etc.
x Press the drain test run switch on the control
board in the control box to start the drain motor
and check whether the water drains normally.
(The drain motor operates for approximately
5 minutes and then stops automatically.)
(See the diagram for “Connecting the
Indoor/Outdoor Connection Cable”.)
