1. Mount the installation plate on the wall with 5 screws or more (at least 5 screws).
(If mounting the unit on the concrete wall, consider using anchor bolts.)
• Always mount the installation plate horizontally by aligning the marking-off line with the thread and using a level gauge.

The meeting point of the extended line is the center of the hole.
Another method is by putting measuring tape at position as shown in the diagram above.
The hole center is obtained by measuring the distance namely 128 mm for left and right hole respectively.
• Drill the piping hole at either the right or the left and the hole should be slightly slanting to the outdoor side.

CONNECT THE CABLE TO THE INDOOR UNIT
The power supply cord, indoor and outdoor unit connection cable can be connected without removing the front grille.
1 Install the indoor unit on the installing holder that mounted on the wall.
2 Open the front panel and grille door by loosening the screw.
3 Cable connection to the power supply through Isolating Devices (Disconnecting means).
• Connect the approved polychloroprene sheathed power supply cord 3 x 1.5 mm 2 (3/4 ~ 1.75HP) or 3 x 2.5 mm
60245 IEC 57 or heavier cord to the terminal board, and connect the other end of the cable to Isolating Devices (Disconnecting means).
•
Do not use joint power supply cord. Replace the wire if the existing wire (from concealed wiring, or otherwise) is too short.
• In unavoidable case, joining of power supply cord between isolating devices and terminal board of air conditioner shall be done by using
approved socket and plug rated 15/16A (3/4 ~ 1.75HP) or 16A (2.0HP). Wiring work to both socket and plug must follow to national wiring
standard.
4 Bind all the power supply cord lead wire with tape and route the power supply cord via the left escapement.
5 Connection cable between indoor unit and outdoor unit shall be approved polychloroprene sheathed 4 x 1.5 mm
2.5 mm 2 (2.0HP) fl exible cord, type designation 60245 IEC 57 or heavier cord.
6 Bind all the indoor and outdoor connection cable with tape and route the connection cable via the right escapement.
7 Remove the tapes and connect the power supply cord and connection cable between indoor unit and outdoor unit according to the diagram below.

1. Please carry out insulation at pipe connection portion as mentioned in Indoor/Outdoor Unit Installation Diagram. Please wrap the
insulated piping end to prevent water from going inside the piping.
2. If drain hose or connecting piping is in the room (where dew may form), please increase the insulation by using POLY-E FOAM with
thickness 6 mm or above.

6. Tighten the service port caps of the 3-way valve at a torque of 18 N•m with a torque wrench.
7. Remove the valve caps of both of the 2-way valve and 3-way valve. Position both of the valves to "OPEN" using a hexagonal
wrench (4 mm).
Mount valve caps onto the 2-way valve and the 3-way valve.

•
Be sure to check whole system for gas leakage.
If gauge needle does not move from 0 cmHg (0 MPa) to –76 cmHg (–0.1 MPa), in step 3 above take the following measure:
•
- If the leak stops when the piping connections are tightened further, continue working from step 3.
- If the leak does not stop when the connections are retightened, repair location of leak.
- Do not release refrigerant during piping work for installation and reinstallation.
- Take care of the liquid refrigerant, it may cause frostbite.

• Open front panel and remove air fi lters.
(Drainage checking can be carried out without removing the front grille.)
• Pour a glass of water into the drain tray-styrofoam.
• Ensure that water fl ows out from drain hose of the indoor unit.
EVALUATION OF THE PERFORMANCE
• Operate the unit at cooling/heating operation mode for fi fteen minutes or more.
• Measure the temperature of the intake and discharge air.
• Ensure the difference between the intake temperature and the discharge is more
than 8°C during Cooling operation or more than 14°C during Heating operation.
