Seasonal Use & Shut Down
During the Swim Season:
• During the swim season, even if the pool or spa is not in use, allow water to flow through the
heater. Doing so eliminates the need to reposition valves when you do wish to heat the pool or
spa.
• During periods when heating or cooling is not desired, leave heater controls in the OFF position.

Winterizing for Hard Freeze Conditions:
Failure to properly winterize heat pump may result in serious equipment damage. Freeze

Information Critical to the
Survival of Your Heater
Follows...
In areas where freezing conditions are a rare occurrence, allow the filtration
system to run continuously throughout the freeze period. Typically, during light
freeze conditions, circulating (moving) water will not freeze.
In areas where freezing conditions are prevalent and sustained, the heat pump MUST be winter-
ized; please refer to winterizing instructions, below, and on the following pages.
While the plumbing connections are in the winterized condition (not fully tightened), it is
imperative pool/spa water not be 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.
Failure to heed the following can result in damage to
equipment and/or property.
