After selecting the best location, start installation according to Installation Diagram.
1. Fix the unit on concrete or rigid frame firmly and horizontally by bolt nut (ø10 mm).
2. When installing at roof, please consider strong wind and earthquake. Please fasten the installation stand firmly

11.4.2.2 Disposal of Outdoor Unit Drain Water
When a Drain elbow is used, please ensure to follow below:
-
the unit should be placed on a stand which is taller than 50 mm.
-
cover the ø20 mm holes with Rubber cap 2 (refer to illustration below).
-
use a tray (field supply) when necessary to dispose the outdoor unit drain water.
If the unit is used in an area where temperature falls below 0°C for 2 or 3 consecutive days, it is recommended
not to use the Drain elbow and Rubber cap, for the drain water freezes and the fan will not rotate.

11.4.3 Connecting The Piping
11.4.3.1 Connecting the Piping to
Outdoor Unit
Decide piping length and then cut by using pipe cutter.
Remove burrs from cut edge. Make flare after
inserting the flare nut (locate at valve) onto the copper
pipe. Align center of piping to valves and then tighten
with torque wrench to the specified torque as stated in
the table.

CUTTING AND FLARING THE PIPING
1. Please cut using pipe cutter and then remove the burrs.
2. Remove the burrs by using reamer. If burrs is not removed, gas leakage may be caused.

Turn the piping end down to avoid the metal powder entering the pipe.
3. Please make flare after inserting the flare nut onto the copper pipes.
When properly flared, the internal
surface of the flare will evenly shine

1 Connect a charging hose with a push pin to the Low side of a charging set and the service port of the 3-way
valve.
Be sure to connect the end of the charging hose with the push pin to the service port.
2 Connect the center hose of the charging set to a vacuum pump with check valve, or vacuum pump and
vacuum pump adaptor.
3 Turn on the power switch of the vacuum pump and make sure that the needle in the gauge moves from
0 cmHg (0 MPa) to –76 cmHg (–0.1 MPa). Then evacuate the air approximately ten minutes.
4 Close the Low side valve of the charging set and turn off the vacuum pump. Make sure that the needle in the
gauge does not move after approximately five minutes.
Note: BE SURE TO FOLLOW THIS PROCEDURE IN ORDER TO AVOID REFRIGERANT GAS LEAKAGE.
Note: BE SURE TO FOLLOW THIS PROCEDURE IN ORDER TO AVOID REFRIGERANT GAS LEAKAGE.
5 Disconnect the charging hose from the vacuum pump and from the service port of the 3-way valve.
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”
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).
8 Mount valve caps onto the 2-way valve and the 3-way valve.
Be sure to check for gas leakage.
CAUTION
If gauge needle does not move from 0 cmHg (0 MPa) to –76 cmHg (–0.1 MPa), in step 11.2.3 above take the following measure:
If the leak stops when the piping connections are tightened further, continue working from step 11.2.3.
If the leak does not stop when the connections are retightened, repair the location of leak.
Do not release refrigerant during piping work for installation and reinstallation. Take care of the liquid refrigerant, it may cause
frostbite.

11.4.6 Pipe
Insulation
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.
