IV. INSTALLING ON 47000 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 47000 series air conditioners, perform the following steps
(refer to Figures 3 and 4).
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 washers.
3. Remove the four keps nuts securing the
evaporator cover and set aside the cover.
4. Referencing Figure 3, scribe two arcs on shroud
and drill a 1 ¼” inch diameter hole at the arc
intersection. This hole is for the solar panel
assembly wiring.
5. Remove the neoprene lined clamp shown in
Figure 4. Place the solar harness assembly (long)
with the unit wiring bundle, allowing 24” between
the clamp and the end of the trailer plug.
Reinstall the neoprene lined clamp securing the
solar harness assembly with the unit wiring
bundle.
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. Route the solar harness along the system wiring
harness. Wire tie the harness to system wiring
bundle. Take up all solar harness slack wire and
drop the harness end into the return air opening
of the basepan.
7. Reinstall the evaporator cover using the keps nuts,
taking care to avoid pinching wiring between
evaporator cover and basepan wall.
8. Reassemble the upper unit shroud, inserting the
trailer plug from the solar harness through the
drilled hole.
9. Insert the plug on the solar panel into the unit cable
plug until they are fully engaged.
10. Insert the plug connection into the hole in the
shroud. It may be necessary to lift the shroud up to
provide clearance for the plugs between the shroud
and the evaporator housing.
11. Secure shroud in place by reinstalling the back two
stainless steel screws and washers.
12. Using the two washers as spacers on the plug end of
the solar panel, reassemble the two screws through
the holes in the solar panel plate and into the threaded
inserts of the roof top unit.
13. 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.
