II. INSTALLING ON 6700 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 6700 series Mach 1, II or III air conditioners, perform the
following steps (refer to Figure 1). Reminder: This kit is not
for use on Super Mach or Delta T air conditioners.
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
acorn nuts and steel 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. 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.
5. Attach the protective edge liner to the condenser
flange by forcing the liner onto the metal edge as
shown in Figure 1. 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.
6. Remove and discard (cut with diagonal cutters or
metal snips) the edge protector bushing entering
the wire box. Take care to prevent nicking any
wire insulation. Route the white connector plug
end of the solar wire harness through the wire box
entry hole. Using the split bushing found in this
kit, surround all wires entering the wire box and
snap the new bushing into the wire box.
7. Using a wire tie provided in this kit, wire tie the
upper unit wire harness to the compressor motor
wires entering the unit wire box. Take up all slack
in the wire harness and insure that no wires can come
into contact with the refrigerant copper lines or any
sharp edges.
8. Remove and discard the strain relief bushing found in
the side panel (refer to Figure 1). Route the solar
harness through the hole in the side panel. Allow
approximately 8” of slack harness wire inside the
wire box and secure all wires to the side panel using
the strain relief found in this kit. It may be necessary
to wrap the wire bundle with electrical tape to
provide a snug fit.
9. Route the white connector plug through the opening
in the basepan along with the existing unit wiring
bundle. Push through all remaining harness wiring
so as to leave a minimum of slack harness in the
upper unit.
10. Before reinstalling the evaporator cover, insure that
all system wires are routed and secured to provide
protection against contact with sharp edges,
refrigerant tubing or moving parts. Insure that no
wires are pinched between metal parts or surfaces, or
can be pierced by assembly fasteners during unit
reassembly. If necessary, use wire ties to provide
wiring security.
11. Before installing 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 1). The harness will be trapped between the
shroud foam blocks and the edge liner after
installation.
12. Position the nylon spacers and the solar panel
assembly as shown in Figure 1 and assemble to the
roof top air conditioner unit with the acorn nuts and
washers previously removed in Step 2.
13. 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.
