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 below. (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.
