Energy Tech Laboratories 8357, 8358, 6356, 6358 Summer Shutdown, Freeze Protection, Maintenance

NOTE: If the pool pump and heat pump pool heater shut OFF before the water temperature is raised to the desired level, you must lengthen the running time of both. To do this, reset the time clock dial for the longer running time, or manually operate the pump with the timer override switch. Since the heat pump pool heater capacity and efficiency are both greater at higher ambient air temperatures, run time should be set to take advantage of all daylight hours, when the air is generally warmer.

4.Set the valves to ensure proper water flow through the unit.

Summer Shutdown

If you do not plan to use the heat pump pool heater during the summer months, secure and protect it as follows:

1.Turn the unit circuit breaker or disconnect switch to OFF.

2.Leave the valves set the way they are unless addi- tional circulation is required. DO NOT stop all flow through the heat pump pool heater.

3.IMPORTANT: Remember to reset the valves before the next heating season, or the unit will not operate properly.

Freeze Protection

If the unit is installed in a location subject to freezing conditions, it is important to protect the water circuit from freezing, just as should be done for the pump and filter.

System Drain-Down

1.Turn the unit circuit breaker or disconnect switch to OFF.

2.With the pool pump OFF, close the external shut- off valves and loosen the inlet and outlet water unions to allow water to drain. Use a Wet/Dry Vac or air pressure to remove excess water.

3.Loosely re-attach the unions.

4.Cover the unit with a waterproof cover.

Continuous Pump Operation

It is also possible in some areas to prevent unit freeze damage by operating the pump continuously during freezing weather. However, this results in significantly higher pump operating costs. Further, if a sustained power failure occurs, the unit MUST be drained any- way, or freeze damage could result.

Maintenance

NOTE: The heat pump pool heater MANUFACTUR- ER IS NOT RESPONSIBLE for maintenance adjustments.

The following maintenance procedures are designed to keep your unit operating at a high level of reliability.

Maintenance must be performed on a periodic basis to maintain warranty coverage and prevent system failures and performance degradation.

Air Coil Cleaning

Efficient operation depends on free circulation of air through the thin and tightly-spaced fins of the evapo- rator coil(s). The evaporator must be cleaned whenever it has a buildup of dirt or debris.

CAUTION: To clean the fins, spray gently with a garden hose. DO NOT pressure wash. Doing so will bend the fins and can void the warranty.

Cabinet Care (optional)

The cabinet is designed for outdoor use and requires little care. However, you can clean it if you wish. Wash the cabinet with soap and water.

WARNING: Shut OFF electricity to the unit before cleaning.

Unplug Condensation Drain Holes

The unit extracts humidity from the air as it passes through the coil, similar to the way a cold drink outside “sweats” on a hot day. This condensation drains from the bottom of the unit.

1.Routinely check to be sure the condensation drain holes in the base of the unit are not plugged with dirt or debris.

2.If condensation becomes a problem, optional drain pans are available from your heat pump pool heater distributor or pool dealer.
