4. Mix Totaline Environmentally Sound Coil Cleaner in
a 2.5 gal (9.5L) garden spryer according to the in-
structions included with the cleaner. The optimum
solution temperature is 100
F (38
C).
NOTE
: Do NOT USE water in excess of 130
F (54
C),
as the enzymatic activity will be destroyed.
5. Thoroughly apply Totaline Environmentally Sound
Coil Cleaner solution to all coil surfaces including
finned area, tube sheets and coil headers.
6. Hold garden sprayer nozzle close to finned areas and
apply cleaner with a vertical, up--and--down motion.
Avoid spraying in horizontal pattern to minimize poten-
tial for fin damage.
7. Ensure cleaner thoroughly penetrates deep into finned
areas.
8. Interior and exterior finned areas must be thoroughly
cleaned.
9. Finned surfaces should remain wet with cleaning
solution for 10 minutes.
10. Ensure surfaces are not allowed to dry before rinsing.
Reapply cleaner as needed to ensure 10--minute satur-
ation is achieved.
11. Thoroughly rinse all surfaces with low velocity clean
water using downward rinsing motion of water spray
nozzle. Protect fins from damage from the spray
nozzle.
Indoor Coil
Cleaning the Indoor Coil:
1. Turn unit power off. Use proper lockout/tagout pro-
cedures.
2. Remove indoor coil access panel.
3. If economizer or two--position damper is installed, re-
move economizer by disconnecting the Molex
plug
and removing mounting screws.
4. Slide filters out of unit.
5. Clean coil using a commercial coil cleaner or dish-
washer detergent in a pressurized spray canister. Wash
both sides of coil and flush with clean water. For best
results, back--flush toward return--air section to re-
move foreign material. Flush condensate pan after
completion.
6. Reinstall economizer and filters.
7. Reconnect wiring.
8. Replace access panels.
Refrigeration System Components:
Each heat pump refrigeration system includes a
compressor, accumulator, reversing valve, dual--function
outdoor coil with vapor header check valve, cooling liquid
line with a filter drier and a check valve, dual--function
indoor coil with a vapor header check valve, and heating
liquid line with check a valve and a strainer. Unit sizes
A04--07 have a single compressor--circuit; unit sizes D08
through D12 have two compressor--circuits. See Fig. 15
for typical unit piping schematic (unit size D09 (4--row
indoor coil) with two compressor--circuits is shown).
Dual--function outdoor and indoor coils are designed to
provide parallel coil circuits during evaporator--function
operation and converging coil circuits during the
condenser--function operation.
