1. Disconnect all electrical power to the heater; turn OFF circulating pump.
2. At the two (2) connection unions, disconnect the plumbing to the heater (removal is counter-
clockwise).
3. Locate the hand drain plug at lower, front corner of heater. See Figure-3 (position may vary
between models). Remove plug.
4. Permit all of the water to drain out of the condenser and then replace the plug; thread the plug in
clockwise until just snug, then apply an additional 1/8 turn.
5. To prevent insects and vermin from entering the plumbing during the winterized period, partially
reconnect the two (2) plumbing connection unions: couple each union one or two threads; this
will permit condensation to drain, but will prevent most insects and animals from entering the
plumbing circuit.
6.
Next Season: To ready the heat pump for use, simply retighten plumbing connection unions.
Hand-tight is generally sufficient.
Winterizing Procedure:
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.
