matching it up with the connecting portion.
2 Secure the slit on the auxiliary pipe side with
the butt joint on the connection pipe using the
tape, making sure there are no gaps.
3 Wrap the slit and the butt joint with the
included insulation sheet, making sure there
are no gaps.

12.1.5 Connecting the Indoor/Outdoor
Connection Cable
Guide connection cable pass through refrigerant
piping port and lead the connection cable into the
control box.
Check the color of the wires on the terminal board
and secure them with screws.
Secure the connection cable with cord holder.
Guide and push the connection cable inside so
that it does not apply undue force on the front
grille.
Fix the connection cable into cable holder.
WARNING
This equipment must be properly earthed.
CAUTION
When the wall is hollow, please be sure to use the sleeve for
tube ass’y to prevent dangers caused by mice biting the
connection cable.
Connection cable between indoor unit and
outdoor unit should be approved polychloroprene
sheathed 4 x 1.5 mm
2
flexible cord, designation
type 60245 IEC 57 (H05RN-F) or heavier cord.
Allowable connection cable length of each indoor
unit shall be 30 m or less.
o
Ensure that the terminal numbers on the
indoor unit are connected to the same
terminal numbers on the outdoor unit by the
right coloured wires as shown in the diagram.
o
Earth lead wire should be longer than the
other lead wires as shown in the diagram for
electrical safety purpose in case the cord slips
out from the anchorage.
Secure the cable onto the control board with the
holder (clamper).
Ensure the colour of wires of outdoor unit and the
terminal Nos. are the same to the indoor’s
respectively.
Earth wire shall be Yellow/Green (Y/G) in colour
and longer than other AC wires for safety reason.
Check for leakage here.
• Apply soapy water and
check carefully for leaking
gas.
• Wipe soapy water off after
the check is complete.
