<PAC-PH01EHY-E>
Step 1. Panel heater wiring
• Wiring on the left side and installing the wiring cover
[Fig. 8.1.0.1]
<A> Pull up the panel heater wirings so that the wirings run
along the left rear pillar.
<B> Thread the panel heater wirings through the long hole
on the left rear pillar.
<C> Attach the rubber sheet to the left frame so that the heat
exchanger fin will be covered. (Using the wiring access
hole and the tab on the frame as a reference position)
<D> Pull the wiring through the hole on the left frame and
bring it into the inner side of the heat exchanger.

• Wiring on the right side and installing the wiring cover
[Fig. 8.1.0.3]
<A> Pull up the panel heater wirings so that the wirings run
along the right rear pillar.
<B> Thread the wiring through the hole on the right rear
pillar and bring it into the inner side of the heat
exchanger.

Step 2. Fastening the panel heater wirings
[Fig. 8.2.0.1]
<A> Run the panel heater wirings outside the unit. Wrap the
supplied pipe cover around the pipe so that the heat
exchanger, refrigerant piping, and sheet metal edges
are out of contact with panel heater wirings located
between the heat exchanger and where indicated as
<A> in the figure. Then fix the pipe cover and the
wirings in place with a cable tie.
<B> Re-place the main control box and the wirings.
