Connect The Cable To The Outdoor Unit; Pipe Insulation - Panasonic CS-CE9LKE Service Manual

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 TAKE 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
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.
• If gauge needle does not move from 0 cmHg (0 MPa) to -76 cmHg (-0.1 MPa), in step
- 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.

11.3.4. Connect the Cable to the Outdoor 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).
• Connect approved type polychloroprene sheathed
power supply cord 3 x 1.5 mm
designation 245 IEC 57 or heavier cord to the terminal
board, and connect the others end of the cord to
Isolating Devices (Disconnecting means).
3. Connecting cable between indoor unit and outdoor unit
shall be approved polychloroprene sheathed 4 x 1.5 mm
flexible cord, type designation 245 IEC 57 or heavier
cord.
4. Connect the power supply cord and connecting cable
between indoor unit and outdoor unit according to the
diagram below.
5. Secure the power supply cord and connecting 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
This equipment must be properly earthed.
• Note: Isolating Devices (Disconnecting means) should have minimum 3.0 mm contact gap.
• Earth wire shall be Yellow/Green (Y/G) in colour and longer than other AC wires for safety reason.

11.3.5. 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 6mm or above.
