Some heat pump owners desire their pool to be heated during the winter months. This is possible when daytime
temperatures are above 50
°
F [10
°
C] for most of Hayward’s heat pumps. If temperatures fall below freezing, be
certain to keep the pool filter pump operating continuously to prevent freeze damage.
WARNING
- While the plumbing connections are in the winterized condition (disconnected from heat
pump), it is imperative that the pool / spa water is NOT circulated through the heat pump. Loss of water through
loose plumbing connections may result in damage to circulating pump, pool / spa structure and / or other
equipment.
