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 will void the warranty.
In areas where freezing temperatures occur, you
should protect your pump, filter, and heat pump from
the elements. Perform the following steps to completely
drain the heat pump (see Figure 19).
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
located on the lower front panel of the heat pump.
4. Open the drain located on the lower front panel of
the heat pump to drain the remaining water from
the heat exchanger. Leave the drain open until the
unit is ready for seasonal start-up. Make sure all
water has drained from the heat pump.

5. 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. Close the petcock located on the lower front panel
of the heat pump.
3. Connect the water inlet and outlet unions located
on the lower front panel of the heat pump.
4. Turn on the fi lter pump to supply water to the
heat pump. Circulate water through the system
long enough to cycle all of the pool water through
the fi lter. Check for leaks in and around the heat
pump.
5. Check the pool chemistry and balance as necessary.
6. Turn on the electrical power to the heat pump at
the main breaker panel.
