    ELECTRICAL CONNECTIONS Field connections must comply with national and local codes. The work must be done by a qualified electrician. Heater must be permanently grounded and bonded.

  • Page 8: Chemical Use

    CHEMICAL USE Water quality must be checked regularly and maintained within recommended limits at all times. Failure to maintain the proper water quality will greatly reduce the life of your heater. • Never add chemicals directly into skimmer. • Automatic chlorinators must be piped downstream from the heater. A check valve must be installed between the chlorinator and heater to prevent raw chlorine from draining back into the heater.

  • Page 9: Start-Up

    START-UP Before proceeding with this section make certain all plumbing connections are airtight and leak free. Flow rates should not exceed 70 GPM maximum. Use of an external bypass is necessary at 70 GPM and above. Minimum flow rate is 20 GPM. •...

  • Page 10: Maintenance

    Because evaporation accounts for about 70 percent of pool heat loss, the beneficial effect of using a pool cover / solar blanket can be dramatic. Wind Speed Reduction Reducing wind velocity at the water surface reduces convective and evaporative losses. Fences, trees, hills, or tall hedges close to the pool perimeter are effective windbreaks.

  • Page 11: Troubleshooting Checklist

    TROUBLESHOOTING CHECKLIST 1. Check to be sure that the electrical power is on. Reset the breakers or replace fuses if necessary. 2. Check to be sure the electronic control panel is set properly. The unit must be in either the Pool or Spa mode and the desired temperature must be set above the actual pool or spa temperature for the heater to run.
