10.3.4 Connect the cable to the Outdoor Unit
1 Remove the control board cover from the unit by loosening the screw.
2
Connection cable
between indoor unit and outdoor unit shall be approved polychloroprene sheathed 4 x
1.5 mm
2
(1.0 ~ 1.5HP) or 4 x 2.5 mm
2
(2.0 ~ 2.5HP) flexible cord, type designation 245 IEC 57 or heavier
cord. Do not use joint connection cable. Replace the wire if the existing wire (from concealed wiring, or
otherwise) is too short.
3 Secure the cable onto the control board with the holder (clamper).
4 Attach the control board cover back to the original position with the screw.
5 For wire stripping and connection requirement, refer to instruction 10.2.4 of the indoor unit.
Earth wire shall be Yellow/Green (Y/G) in colour and longer than the other AC wires for safety reason.
10.3.5 Piping
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.
10.3.5.1
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 are 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.
