HEATING QUICK START AND STOP
1. Verify Electrical Power is Present at Heater:
A. Ensure that the unit has electrical power connected; the heater controller
display should be illuminated.
B. If the display is blank, be certain the electrical breaker, and heater disconnect,
are switched to “ON.”
C. For now, leave the water circulation pump OFF.
2. Set the Heater Controls (Refer to Control Panel Layout, page 4)
If heater is connected to a Call-Flex controller, please reference installation
manual for details.
A. The user/owner settings can be made without water flowing. Once the
heater has electrical power connected, with water not flowing, the display
should read FLO.
B. Press the MODE button until the HEAT (HEA) indication displays. This
will enable the remaining programming keys.
C. Using the POOL / SPA selector key, select the POOL mode. An illuminated
POOL indicator light, located on the left side of the display, will confirm the
POOL control has been selected. If heating only a spa, using the DOWN
arrow key, lower the POOL temperature until OFF is displayed; then proceed
to Step-“E.”
D. Use the UP / DOWN arrow keys to set the desired water temperature for
the POOL water.
E. If the heat pump will be used to heat a spa, use the POOL/SPA selector key
to select SPA, then use the UP / DOWN arrow keys to set the desired water
temperature for the SPA. An illuminated SPA indicator light, located on
the left side of the display, will confirm the SPA control has been selected.
If heating only a POOL, using the DOWN arrow key, lower the SPA
temperature until OFF is displayed.
F. The heat pump controls are now set to maintain the desired water temperature
for the POOL and/or SPA.
3. To Begin Heating:
A. Verify MODE is set to: HEAT (HEA); then, depending on which body of
water is to be heated, use the POOL / SPA selector key to select POOL or
SPA.
B. Position water valves to flow water from the pool or spa, through the
heater, and back to the pool or spa.
C. Start the water pump; the fan will start, and after 4-minute time delay the
unit will begin heating. The selected body of water will be brought to

5. Replace the winterizing plug; thread the plug in clockwise until just snug,
then apply an additional 1/8 turn. To prevent insects and critters 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.
