Installation and Operation Manual
Section 6. General Maintenance
6.1
Water Chemistry
Proper chemical balances are necessary for sanitary
bathing conditions as well as ensuring your heat pump’s
long life. Be sure to keep your chemical and mineral
concentration levels within the values indicated in
Table 3.
NOTE
For spas, it is also necessary to perform water
changes in addition to chemical treatment. It is
recommended to change the spa water every
60 days for light usage and every 30 days if
usage is heavy.
6.2 Winterizing
CAUTION
Failure to winterize could cause damage to the
heat pump and may void the warranty.
In areas where freezing temperatures occur, you should
protect your pump, filter, and heat pump from the ele
-
ments. Perform the following steps to completely drain
the heat pump (see Figure 14).
1. Turn off the electrical power to the heat pump at
the main breaker panel.
2. Shut off the water supply to the heat pump.
3. Disconnect the water inlet and outlet unions
4. Cover only the top of the heat pump to prevent
debris from falling into the unit. Do not wrap the
sides of the heat pump with any plastic or other
material that will retain heat or moisture inside
the unit.
6.3
Spring Start-Up
If your heat pump has been winterized, perform the
following steps when starting the system in the Spring:
1. Uncover the heat pump and inspect the top and
sides for any debris or structural problems.
2. Connect the water inlet and outlet unions located
on the lower front panel of the heat pump.
3. Turn on the filter pump to supply water to the
heat pump. Circulate water through the system
long enough to cycle all of the pool water through
the filter. Check for leaks in and around the heat
pump.
4. Check the pool chemistry and balance as
necessary.
5. Turn on the electrical power to the heat pump at
the main breaker panel.
6.4
Inspection and Service
Jandy heat pumps are designed and constructed to
provide long performance life when installed and
operated properly under normal conditions. Periodic
inspections are important to keep your heat pump
running safely and efficiently through the years.
Owner Inspection
CAUTION
Do not use this heat pump if any part has been
under water. Immediately call a qualified service
technician to inspect the heater and replace any
part of the control system which has been under
water.
Jandy recommends that you inspect your heat pump on
a regular basis and especially after abnormal weather
conditions. The following basic guidelines are suggested
for your inspection:
1. Keep the top and surrounding areas of the heat
pump clear of all debris.
2. Keep all plants and shrubs trimmed and away from
the heat pump.
