SECTION G: POOL HEATING

CAUTION:

Power to the heater should be interlocked with the main system pump to make sure the heater does not fire without the main system pump in operation. Improper flow control can damage the heater. Uncontrolled flow (too high) or restricted flow (too low) can seriously damage the heater. Follow these instructions to make sure your heater is properly installed.

The Hi Delta pool heater is equipped with an external pump and bypass arrangement that blends outlet water with the inlet to increase the inlet water temperature, thereby reducing the likelihood of condensation forming on the heat exchanger. The pump also serves to circulate water through the heater from the main system piping.

To complete the installation of the pool heater, the pool thermostat needs to be installed in the main return water line. This will insure that the heater will be energized at the right time. If the main water line is too far away from the heater and the capillary bulb will not reach it, locate the pool thermostat adjacent to the main line and run wires back to the heater. See Figure #9225.

Adjustment of the bypass valve is critical to proper operation of the heater. The bypass valve should be adjusted to achieve a minimum inlet water temperature of 105°F and an outlet water temperature between 120°F and 140°F. When starting with a cold pool, make initial adjustments. Make final adjustments when pool water approaches desired temperature.

AUTOMATIC CHLORINATORS AND CHEMICALFEEDERS

All chemicals must be introduced and completely diluted into the pool or spa water before being circulated through the heater. Do not place chlorine tablets or bromine sticks in the skimmer. High chemical concentrations will result when the pump is not running (i.e. overnight).

Chlorinators must feed downstream of the heater and have an anti-siphoning device to prevent chemical backup into the heater when the pump is shut off.

NOTE: High chemical concentrates from feeders and chlorinators that are out of adjustment will cause very rapid corrosion to the heat exchanger in the heater. Such damage is not covered under the warranty.

WINTERIZINGYOU HEATER

When heaters installed outdoors in freezing climate areas are to be shut down for the winter, please observe the following procedure:

1.Heaters installed outdoors in freezing climate areas should be shut down for the winter. To shut down heater, turn off manual main gas valve and main gas shut-off. Close isolation valves and remove water piping from the in/out header of the heater. Drain the heater and any piping of all water that may experience below freezing temperatures.

POOLAND SPA WATER CHEMISTRY

NOTE: Chemical imbalance can cause severe damage to your heater and associated equipment. Maintain your water pH between 7.4 and 7.8 and total alkalinity between 100 and 150 p.p.m. If the mineral content and dissolved solids in the water become too high, scale forms inside the heat exchanger tubes, reducing heater efficiency and also damaging the heater. If the pH drops below 7.2, the heater will be severely damaged.

NOTE: Heat exchanger damage resulting from chemical imbalance and/or scaling is not covered under the warranty.
