HEATE r O n/OFF:
To start the heater press this button and it’ s green light will come on. T o disable the heater press
this button and its green light will go of f.
THEr MOSTA T BUTT On S:
Pressing the + button will raise the set temperature. Pressing the - button will lower the set tem -
per atu re. W hen ei the r b utto n is pr ess ed the LE D d isp lay w ill beg in to flas h. The fla shi ng num ber s
indicate the thermostat setting.
MODE SELECT BUTT On S-POOL or SPA:
The heater has two thermostat modes for two dif ferent desired temperature settings, one for pool
mode and one for spa mode. If you do not have a spa use the pool mode only . If you do have a
spa, you can connect two Jandy™ motorized plumbing valves. Therefore, when you select either
mode the motorized valves will turn to isolate the heater to either the pool or spa. NOTE: There
is a 30 second delay when switching pool/spa modes.
“OPT IO nA L” WA TE r P UM P T IM E C LO CK O VE rr ID E OPE rA TIOn
When the T.C.O. button is set to the ON mode, the T ime Clock Override feature is designed to
start the water pump whenever the pool requires heat. Once the pool is up to the set temperature
the heater will stop and then 5 minutes later the water pump will stop. When this button is set
to the OFF mode, the heater will operate only when the water pump is running during the timed
period set on the water pumps time clock.
nOTE: The time clock override works best if used during cooler weather conditions where the
pool is losing more than 8 to 10 degrees over night or when the pool is being heated from “dead
cold”.
nOTE: If the time clock override starts the water pump and the thermostat does not continue to
call for heat for at least 5 minutes, the control will shut the water pump and heater of f. Thereafter ,
it will not re-attempt to start the water pump for 4 hours. This 4 hour delay can be bypassed by
pressing the T.C.O. button of f then back on.
nOTE: When the T.C.O. button is activated while in “spa mode” the water pump will run the
entire time you are in spa mode. When you switch back to pool mode there will be a 5 minute
delay before the water pump shuts of f. The T .C.O. option is built into the heater at the factory
and can not be added later .

(Air temperature does not remain below 32ºf for more than 4-hours)
In the event your heater will not be used for an extended period, it is recommended pool water
be allowed to circulate through the heater during normally scheduled filtration cycles. If light
freeze conditions are expected, adjust water pump controls for continuous operation throughout
the light freeze episode. Moving water will not freeze under light-free ze conditions. Remain
aware of abnormal climatic conditions; use “hard-freeze” instructions (Below) if freezing
conditions will exceed 4-hours.

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
counterclockwise).
3. Locate the drain plug at outside, lower front of heater . (see figure 1)
If the unit does not have an external drain plug, remove the exterior front panel of the unit.The
internal drain plug is located at the base of the heat exchanger (see figure 2). Follow the same
procedure as with an external drain plug.
4. Using a 5/8”, box-end wrench, remove the drain plug (removal is Counterclockwise).
5. Permit all water to drain from the condenser and then replace the plug: thread the plug in
clockwise until just snug, then apply an additional 1/8 turn.
6. 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.
7. Next season: to ready the heat pump for use, simply retighten plumbing connection unions.
Hand-tight is generally sufficient.
