III. INSTALLING ON 7000, 8000 AND 48000
SERIES AIR CONDITIONERS
WARNING – SHOCK HAZARD
To prevent the possibility of severe personal injury or
equipment damage due to electrical shock, always be sure
the electrical power to the appliance is disconnected.
To install the solar panel and through-way wiring of this kit to
the 7000, 8000 and 48000 series air conditioners, perform the
following steps (refer to Figure 2).
1. If the air conditioner is a new installation, follow
instructions found with the air conditioner to
complete the unit installation.
2. Remove the upper unit shroud by removing the four
stainless steel screws and black nylon washers.
3. Remove the sheet metal screws securing the
evaporator cover and set aside the cover. Take care
in handling sheet metal edges as they can be quite
sharp.
4. Remove the left side panel and wire box cover (as
shown in Figure 2) and set aside.
5. Using the neoprene lined steel clamp provided in this
kit, secure the upper unit wire harness (Solar Harness
Assembly Long) to the condenser panel as shown in
Figure 1. Allow 24” between the clamp and the end
of the trailer plug.
NOTE
The trailer plug is provided with a blocking
diode molded in and will pass current in one
direction only. Keep this in mind if checking
the upper unit wire harness for continuity.
6. Attach the protective edge liner to the condenser
flange by forcing the liner onto the metal edge as
shown in Figure 2. Insure that the edge liner is
securely installed. Cut off any excess edge liner
length which may extend beyond the condenser
header plate. Use a diagonal cutter for this purpose
as the edge liner contains spring steel sections.
Wear eye protection when cutting edge liner.
7. Route the solar harness along the liquid line and
capillary tube(s) and through the foam blocks as
shown in Figure 2. Secure the solar harness to the
large refrigeration line (suction line) using a wire tie
found in this kit. It may be necessary to remove and
reinstall the foam blocks in order to route the solar
harness through the blocks.
8. Route the solar harness under the evaporator drain
pan along with the system wiring harness. Wire tie
the solar harness to the system wiring bundle. It will
be necessary to gently pry up the drain pan to fish
through the white connector plug. Take up all solar
wire harness slack wire and drop the harness end into
the return air opening of the basepan. Insure that the
drain pan is not out of position over the pan outlet
after completion of wiring.
9. Reinstall all panels, taking care to avoid piercing
tubing or wiring with assembly screws or pinching
wiring between panels.
10. Before reinstalling the shroud, position the trailer
plug and solar harness outboard of the condenser coil
so that it may be routed through the condenser air
inlet of the shroud as the shroud is being reinstalled
(See Figure 2). The harness will be trapped between
the shroud foam blocks and the edge liner after
installation.
11. Position the nylon spacers and the solar panel
assembly as shown in Figure 2 and assemble to the
roof top air conditioner unit with the stainless steel
screws and nylon washers previously removed in
Step 2.
12. Insert the plug on the solar panel assembly into the
solar harness plug until they are fully engaged.
Optional: Spray the connection with a good quality
spray to protect against corrosion. This type of
product is readily available at most auto supply or
hardware outlets for protection of rubber and
thermoplastic insulated wiring.
Clean the solar panel glass surface with any good
quality glass cleaner (non-abrasive) to remove any
smudges or fingerprints encountered during handling.
Installation of the upper unit through-way wiring is
now complete.
