General Maintenance

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 1.

Failure to maintain proper water chemistry may void the warranty.

Test

Recommended Level

 

 

Free Chlorine or

1.0 to 3.0 ppm (3.0 to 5.0 spa)

 

 

Bromine

2.0 to 4.0 ppm (3.0 to 5.0 spa)

 

 

pH

7.4 to 7.6

 

 

Total Alkalinity (TA)

80 to 120 ppm

 

 

Calcium Hardness (CH)

200 to 400 ppm

 

 

Cyanuric Acid

30 to 50 ppm

 

 

Total Dissolved Solids (TDS)

Less than 2000 ppm

 

 

Copper

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.

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 16.

1.Turn off the electrical power to the heat pump at the mainbreakerpanel.

2.Shut off the water supply to the heat pump.

3.Disconnectthewaterinletandoutletunionslocatedon the lower front panel of the heat pump.

4.Coveronlythetopoftheheatpumptopreventdebris fromfallingintotheunit.Donotwrapthesidesofthe heatpumpwithanyplasticorothermaterialthatwill retainheatormoistureinsidetheunit.
