• Allow the heat pump pool heater and the pool filter pump to operate continuously until the desired pool water temperature is reached. This is best accomplished by removing the pool pump timer cogs (stops). This prevents the pump from cycling off and allows for continuous operation. To achieve optimum heating efficiency, a pool cover should be used. Occasional Pool Use Heat pumps are NOT fast pool heaters. You must allow at least 48 hours before swimming for the pool to be noticeably heated. If you are only using your pool on the weekends, it is more economical to turn the heat pump down a few degrees and cover the pool. When you are ready to swim again, it will require less energy and time to regain a preferred temperature. It will take several days of continuous operation for your pool to heat up to temperature. The exact length of time will vary depending on pool size, ambient temperature, wind speed, and use of a cover. If you are not planning on swimming for a month or longer, you may choose to turn the heat pump off. In this instance, it is recommended that the heat pump be drained of pool water and bypassed. Summertime Shutdown During the summer months, when the heat pump is not needed, you can shut the unit off. In this instance, it is recommended that the heat pump be drained of pool water and bypassed. It is also recommended leaving the cover off as well to take advantage of solar warming effects. End of season (Winterizing) Many pool service companies offer "winterizing" assistance. We recommend using them for this procedure. • Perform the cleaning procedures recommended above. • Disconnect the power supply (usually at the circuit breaker in your house). • If you are closing the pool for the winter, BE ABSOLUTELY CERTAIN TO DISCONNECT THE HEAT PUMP FROM THE UNIONS AND DRAIN ALL WATER LINES. As an alternative, you may prefer to fill the water lines with a suitable antifreeze solution. Note: the 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 desire their pool heated during the winter months. This is possible when daytime temperatures are above 50° F (10° C). If nighttime temperatures fall below freezing be certain to keep the pool filter pump operating continuously during this time to prevent freeze damage. 14
