To Winterize a Titanium Heat Pump Equipped with an Internal Drain

1. Disconnect all electrical power to the heat pump; turn OFF circulating pump.
2. At the two (2) connection unions, disconnect the plumbing to the heat pump (removal is counter-clockwise).
3. Remove the front plastic panel by removing the screws shown in Figure-1.
4. Locate the drain plug at base of the titanium condenser and remove (removal is counter-clockwise). See Figure-2.
5. Permit all of the water to drain out of the condenser and then, threading clockwise, replace the plug finger-tight.
6. Reinstall the heat pump front cover and secure with attaching screws previously removed.
7. 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.
8. Next Season: to ready the heat pump for use, simply re-tighten plumbing connection unions. Hand-tight is generally sufficient.

To Winterize a Titanium Heat Pump Equipped with an External Drain

1. Disconnect all electrical power to the heat pump; turn OFF circulation pump.
2. At the two (2) connection unions, disconnect the plumbing to the heat pump
   (removal is counter-clockwise).
3. At the two (2) connection unions, disconnect the plumbing to the heat pump
   (removal is counter-clockwise).
4. Locate the drain plug at lower, right-hand, front corner of heat pump. See Figure-3.
5. Using a 5/8”, box-end wrench, remove the drain plug (removal is counter-clockwise).
6. 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.
7. Next Season: to ready the heat pump for use, simply re-tighten plumbing
   connection unions. Hand-tight is generally sufficient.
