Aquacal 155, 120 owner manual Winterizing Procedure

MAINTENANCE & OPERATION (continued)

Winterizing Procedure:

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.

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.
