Continuous Operation for Heating:

• To achieve the desired pool water temperature, allow both the heat pump pool heater and the pool filter pump to operate continuously. Remove the pool pump timer stops (cogs) to prevent cycling off and ensure continuous operation.
• Using a pool cover is recommended for optimal heating efficiency. The cover helps retain heat and reduces energy consumption.

Heating Time Considerations:

• Heat pumps are not fast pool heaters. It may take several days of continuous operation to heat the pool to the desired temperature.
• For occasional pool use, allow at least 48 hours (depending on pool size, ambient temperature, and wind conditions) before swimming for the pool to be noticeably heated.
• If the pool is only used on weekends, it’s more economical to turn the heat pump down a few degrees and cover the pool. When ready to swim again, it will require less energy and time to regain the preferred temperature.

Summertime Shutdown:

• During the summer months when the heat pump is not needed, shut the unit off.
• It is recommended to drain the heat pump of pool water and bypass it. Leaving the cover off takes advantage of solar warming effects

• Many pool service companies offer assistance, which involves:
  • Performing cleaning procedures recommended for the pool and the heat pump.
  • Disconnecting the power supply, usually at the circuit breaker in the house.
  • If closing the pool for winter, disconnect the heat pump from the unions and drain all water lines. Alternatively, fill the water lines with suitable antifreeze solution. Water lines are best drained when compressed air is forced through them.
  • Cover the heat pump to protect it from snow and water, which could freeze and damage the unit.
• Some heat pump owners may desire pool heating during winter months when daytime temperatures are above 50°F (10°C). If nighttime temperatures fall below freezing, keep the pool filter pump operating continuously to prevent freeze damage.
