OPERATION OF YOUR POOL HEAT PUMP

Initial Heating

To achieve initial heating, your pool heat pump and the pool pump may require extended operation
until desired temperature is achieved. The initial heating time may vary depending upon the five
factors listed below. After initial heating, operating time may be reduced to match daily heat loss.
1. Size of the pool.
2. How many degrees the water is to be heated.
3. Ambient air temperature - the warmer the air, the less time required to heat.
4. Use of a solar blanket .
5. The size of the pool heat pump.
Atmospheric conditions as well as the pool water temperature should not be below the minimum
operating temperatures as stated below in order to obtain efficiency and avoid codes from
appearing on the electronic control temperature display ; these codes are not generally a problem
with the pool heat pump at these conditions and is not covered by the warranty.
If a combination of the atmospheric and water temperatures are below the minimum listed
concurrently the pool heat pump should not be operated and be switched off.
Generally, atmospheric conditions (air temperature) will be warmer during day time hours. To
accelerate the initial heating period owners may opt to increase the ambient air temperature
artificially around the evaporator area of the pool heat pump until the pool water temperature has
reached the minimum required as stated below.
For Electroheat Ultra, Inverter and Reversible (XLR) units, they will automatically stop without
human intervention.

Adjustment Of The Bypass Valves

The adjustment may vary according to pool pump size and ambient temperatures.
ATTENTION: IT IS VERY IMPORTANT THAT THE BYPASS VALVES ARE SET AS DESCRIBED BELOW

Pool Heat Pump Running Time

Most units should be sized to operate during the pool filtering cycle time of 8-12
daytime hours daily during warmer months and up to 8 hours daily during the
daytime in winter months. On warmer days the pool heat pump will run less
because the heat loss will be less.
IMPORTANT
Condensation
Your pool heat pump will accumulate condensed water (approx. 1 to 1.5 gallons or 4
to 6 litres per hour), therefore causing water to drain out of the unit base. In order to
avoid water accumulation, you may use decorative rocks around the concrete slab or
a basin under the unit. (Please note this is a normal characteristic of a pool heat pump
and not a service or warranty issue.)

Pool Solar Blanket

A pool solar blanket should be used whenever possible. Blankets minimize heat loss
through evaporation and conserve heat in your pool. Un-blanketed pool can lose
2-3 times more heat than a blanketed pool.

Defrost Cycle

When any of the following conditions occur the electronic control of your unit will
activate a defrost mode until all frost from the evaporator has melted. Condensation
of water on the evaporator coil tends to frost up quicker when the following occur.
1. When atomospheric conditions are as stated above;
2. When the evaporator is dirty;
3. When installation clearances are not respected.
Defrost is activated for between 3 to 20 minutes.
