Cord heater installation work
Drill a hole on the outdoor unit base plate, and fix the cord heater to the outdoor unit base plate using
P-shape clamp.
Connect the cord heater cables.
Using a motor drill, etc., drill Ø3.2 holes on the outdoor unit base plate.
See APPENDIX-1 and 2 for the additional hole positions.
These holes are used to fix the cord heater to the outdoor unit base plate with P-shape clamp.
Insert the PVC tube into the cord heater.
This tube is designed to protect the cord heater
from the fixing screws used to secure the
anchoring feet.
As shown in the left figure, install the cord
heater (1.5m) to the outdoor unit base plate by
using P-shape clamp and screws (Self-tapping
screw type-B Ø4 × 6mm, stainless).
Pay attention to the direction of P-shape clamp
so that it is set to the same direction in the left
figure.
* If the drain port is frozen due to installation
status, etc., draw around the cord heater so
that the end part of the heater is inserted into
the drain port. In this case, add some fixing
positions to fix the cord heater surely.
* The end part from the marked part of the cord
heater heats up. When there is the heating
part near the electric parts box, a fire may
generate. Be sure to set the heating part on
the outdoor unit base plate at the fan room
side or near it. (within 20cm from the outdoor
unit base plate)
* Be careful that the cord heater does not hit
the fan.
Fix the cord heater without any loosening or
sag.
Drill a hole on the side cabinet (R) for fixing the
thermostat fixing plate.
Ø5 hole at two positions
When drilling a hole on the side cabinet (R), be
sure not to damage the cabinet.
