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.
o
Be sure to check for gas leakage.
If gauge needle does not move from 0 cmHg (0 MPa) to -76 cmHg (-0.1 MPa), in step
above take the following measure:
If the leak stops when the piping connections are tightened further, continue working from step
.
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.
11.2.5 CONNECT THE CABLE TO THE OUTDOOR UNIT
(FOR DETAIL REFER TO WIRING DIAGRAM AT UNIT)
1 Remove the control board cover from the unit by loosening the screw.
2 Cable connection to the power supply through Isolating Devices (Disconnecting means).
o
Connect approved type polychloroprene sheathed
power supply cord
3 x 1.5 mm
2
type designation
60245 IEC 57 or heavier cord to the terminal board, and connect the others end of the cord to Isolating
Devices (Disconnecting means).
3
Connection cable
between indoor unit and outdoor unit shall be approved polychloroprene sheathed 4 x
1.5 mm
2
flexible cord, type designation 60245 IEC 57 or heavier cord. Allowable connection cable length of
each indoor unit shall be 30 m or less.
4 Connect the power supply cord and connection cable between indoor unit and outdoor unit according to the
diagram below.
5 Secure the power supply cord and connection cable onto the control board with the holder.
6 Attach the control board cover back to the original position with screw.
7 For wire stripping and connection requirement, refer to instruction 11.1.6 of indoor unit.
o
Note: Isolating Devices (Disconnecting means) should have minimum 3.0 mm contact gap.
o
Earth wire shall be Yellow/Green (Y/G) in colour and longer than other AC wires for safety reason.
11.2.6 PIPE
INSULATION
