SEASONAL CLEANING
Ⅲ ACCESSING THE INDOOR AND OUTDOOR
COILS — The minimum cleaning recommendation for
indoor and outdoor coils is once per season. To access
the coils for a thorough cleaning, it is necessary to
remove the Air System. To accomplish this task, per-
form the following steps:
1. DISCONNECT ALL POWER TO UNIT!
2. Remove the unit chassis from the sleeve as described
in the General Disassembly section of this manual.
See Figure 6.
3. Remove each side angle from unit with a
5
⁄
16
-in. nut
driver. See Figure 25.
4. Locate and disconnect wires from the compressor.
Label each wire for easy reassembly.
For compressors that are known to be dam-
aged: Remove refreigerant prior to disconnecting
compressor wires. Damaged hermetic compressor ter-
minals may become loose and eject from the com-
pressor. Wear safety glasses and keep your face away
from the area above the terminals when removing
compressor wires.
5. For Heat Pump Units — Disconnect the wire plug
on the reversing valve and carefully remove the out-
door thermostat capillary from the outdoor coil.
6. With a
5
⁄
16
-in. nut driver, locate and remove the
8 screws mounting the fan section to the chassis. See
Figures 26 and 27.
7. Using a flat head screw driver, gently pry the plastic
condenser orifice tabs away from both outdoor coil
tube sheets and pull the condenser orifice away as
shown in Figure 19. See GENERAL DISASSEMBLY
section.
8. Carefully remove the fan section from the chassis
by lifting fan section straight up and out. The fan
deck is awkward; 2 people may be needed for its
removal.
9. Remove the stator from the outdoor coil. See
GENERAL DISASSEMBLY section. After cleaning,
reassemble by reversing steps1-8.
IMPORTANT: During reassembly of the fan section,
carefully align the rubber seal around the tubing where
it passes through the partition.
