SEASONAL USE & SHUT DOWN
DURING THE SWIM SEASON
o During the swim season, even if the pool or spa is not in use, allow water to flow
through the heater.
o This eliminates the need to reposition valves when you do wish to heat your pool
or spa.
FREEZE PROTECTION / EXTENDED SHUT DOWNS
o In areas where freezing conditions are a rare occurrence, allow the filtration
system to run continually through the freeze period. Typically, during light
freeze conditions, circulating water will not freeze.
o In areas where freezing conditions are prevalent, please refer to winterizing
instructions following this section.
