the pump from cycling off and allows for continuous
operation. To achieve optimum heating efficiency, a pool

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.
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
