Air Coil Cleaning
Efficient operation depends on free circulation of air
through the thin and tightly-spaced fins of the evaporator
coil(s). The evaporator must be cleaned whenever it has a
buildup of dirt or debris.
Cabinet Care (optional)
A
WARNING: Shut OFF electricity to the unit before
cleaning.
The powder-coated cabinet is designed for outdoor use
and requires little care. However, you can clean it if you
wish. Wash the cabinet with soap and water.
Unplug Condensation Drain Holes
The unit extracts humidity from the air as it passes through
the coil, similar to the way a cold drink outside "sweats"
on a hot day. This condensation drains from the bottom
of the unit.
1. Routinely check to be sure the condensation drain
holes in the base of the unit are not plugged with dirt
or debris. See Figure 60 for condensate drain hole
locations.
2. If condensation becomes a problem, optional drain
pans may be available from your heat pump pool
heater distributor or pool dealer.

21. TROUBLESHOOTING
Before troubleshooting the system, ensure that:
•
All mechanical and electrical connections are secure
and tight
•
All system wiring is correct
•
Fuse is not blown (3A Automotive "ATO" type fuse
for 24VAC)
•
That a system ground is properly connected to the
heater. Nuisance shutdowns are often caused by a
poor or erratic ground.
The service display can be accessed by pressing
SERVICE key
.
The service display does not affect operation of the unit
which continues to operate in the background. When in
this menu, the UP or DOWN buttons will toggle through
the various information reported. For more details about
Service menu, refer to section 11 "Service Menu", on
page 14.
If your unit does not operate, or simply does not heat
your pool water, fault messages on the front control
panel can provide valuable clues as to what is wrong,
and may even indicate precisely what the problem is.
Always observe these messages before calling a service
representative. By reporting on the telephone the fault
messages that are showing, the service representative
may be able to solve the problem without the expense
of a service call.
A. Unit Is Running, But Not Heating
•
Is water flow through the unit adequate? Check
the unit for obstructions, such as a clogged filter
pump strainer, a dirty filter, or valves not positioned
correctly.
•
Is the ejected air from the unit 8°–10°F (4.4°C–5.5°C)
cooler than incoming air? If so, the unit is extracting
heat from the air and transferring it to the pool.
•
Is water condensing on the evaporator and internal
copper pipes? This is also evidence of heat removal
from the air. When the air is cool with low humidity,
condensation may not be evident.
•
How long has the unit been operating? During initial
pool heating in cold weather, it may require a week to
elevate the water temperature to a comfortable level.
Normally, it takes about 4-days.
•
How many hours per day is the unit operating?
Remember that the heater only operates while
the pool pump is running. Set the time clock to
permit 24-hour per day operation. After the desired
temperature is reached, return the unit to normal
operation of 8–10 hours per day.
