AT START UP: CONTINUOUS CIRCULATION

PUMP OPERATION REQUIRED

When starting a heat pump for the first time, it must be permitted to operate, continu-

ously, until the desired water temperature is attained. This may take several hours,

to several days, depending upon the size of the pool or spa and weather conditions.

If a time clock or similar device controls the operating times of the water circula-

tion pump, temporarily override the water pump controller, allowing for 24-hour,

continuous water pump operation.

Once the body of water has reached the desired temperature, the water pump

controller can be reset.

Seasonal Use & Shut Down

During Swim Season

•

During the swim season, even if the pool or spa is not in use, allow water to

flow through the heater. Doing so eliminates the need to reposition valves

when you do wish to heat the pool or spa.

•

During periods when heating or cooling is not desired, leave heater controls

in the OFF position.

Freeze Protection & Extended Shut Down

In areas where freezing conditions are a rare occurrence, allow the filtration system

to run continuously throughout the freeze period. Typically, during light freeze

conditions, circulating (moving) water will not freeze.

In areas where freezing conditions are prevalent and sustained, the heat pump

MUST be winterized; please refer to winterizing instructions, below, and on the

following pages. Failure to properly winterize your heat pump could result in

permanent damage to the unit.

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. If your unit has an external drain plug, remove plug. This plug would be

located at lower, front corner of heater. (position may vary between models).

Allow water to drain out of the condensor. DO NOT replace plug until final

winterizing step.

4. If no external drain plug is found, it will be necessary to open access panel

and see if heat exchanger has an internal drain plug. If so, remove plug, and

allow water to drain out of the condensor.

temperature and maintained per the setting determined previously in:

"Set the Heater Controls."

In operation, whenever the actual (displayed) water temperature falls

below the desired set point, after an initial time delay of 4-minutes,

the unit will begin heating.

THE HEATER CONTROLLER HAS AN ANTI-SHORT CYCLE

TIME DELAY. IF OPERATION IS INTERRUPTED,

COMPRESSOR RESTART WILL BE DELAYED

BY APPROXIMATELY 4 MINUTES.

4. Program Filter Pump Run Time:

Most pool/spa systems utilize a timer or multifunction controller to manage

filter pump run times. If your system incorporates such a device, follow the

instructions below:

A. It will be necessary to allow the filter pump to run continuously until the

water has reached the desired temperature. If a timer controls the pool filter

pump, it will be necessary to override the timer to allow 24-hr. operation.

B. Once the desired temperature has been obtained (1-4 days), reset the pump

control device. Colder months require longer running times - generally

eight to twelve hours/day.

C. A heat pump can only operate when the filter pump is running. Therefore,

it may be necessary –during cooler weather–to extend the water pump's

hours of daily operation. The increased run time is necessary in order

to keep up with increased, weather-related heat losses.

5. Continuous Usage and Water Around Heater:

CONDENSATION

After the heat pump has been operating for some time, water may be observed

surrounding the heater. The moisture seen is condensation produced as a normal

by-product of transferring heat from the air into the pool or spa water. Quantities

of 6-8 gallons of water produced per hour are common if the air humidity

is high. Conversely, a low humidity condition may result in no condensation

being produced. (If water around unit seems excessive, to troubleshoot, see

page 26, "Water Coming from the Heat Pump.")

6. To Stop the Heat Pump:

A. Select: OFF via the MODE selector. This method of shut down

preserves the controller settings.

B. An interruption of water flow–such as when a pump timer is in

control–will also halt heat pump operation.
