6 Securing the lead wires
Place the base heater covers
,
as shown in
the right photo.
Fix them with the screws 4×10
.
• Make sure to install the base heater covers
,
in the outdoor unit mounted with a two-row
heat exchanger. The base heater covers
,
cannot be installed in the outdoor unit mounted
with a three-row heat exchanger.
Fix the lead wires of the base heater to the
motor support with a cable tie
at the
position shown in the picture.
Bundle the lead wires of the base heater and
the fan motor together with clamps.
Fix the lead wires with a cable tie
.
Pass the lead wires through the circular hole
on the separator toward the electrical box.
• Secure the lead wires so they will not interfere
with the propeller fan.
