SAFETY PRECAUTIONS

Pool He t Pump _6
OPERATING THE POOL HEAT PUMP
The DPL Swimming Pool Heat Pump is designed for easy operation. The side panel contains a digital
temperature control readout. The Heat Pump is set to reach and then maintain the selected pool water temperature, as
long as the pool pump is running.
To start the unit:
> Press the button . In normal operating mode, the display indicates the water temperature in centigrade degrees.
To stop the heat pump, press the button.
To adjust the temperature to the desired value:
> Press the button until the red pilot light turns on.
> To adjust the water temperature, press the or buttons until the targeted temperature is displayed.
The available temperature range is between 18 °C and 35 °C.
> To return to normal operating mode, press the SET button again, for at least 5 seconds.
The pilot light turns on whenever the heat pump is in operation, which means that the ventilator(s) and the compressor
are functioning in order to heat the pool.
All models use a 5-minute time delay to prevent repeated tripping of the compressor's overload protection mechanism, which is
caused by attempting startup before system pressures are equalized. Any interruption will result in a 5-minute time delay.
The pilot light will blink during this 5-minute time delay.
To display the temperature in farenheit (°F) or celcius (°C), press the and buttons simultaneously
for 3 seconds to select the desired temperature scale.
Warning:
Prior to starting the heat pump, you must ensure that:
> There is electricity supplied to the heat pump.
> The filter pump is operating with a minimum water circulation of 22,5 gallon/min.
If these two conditions are not met, it will be the heat pump will not start. In such a case, the digital display thermometer
will be unusable.
TIP:
Setting the thermostat to its highest setting will not heat the water faster than setting it at the desired temperature.

Beginning of season:
> Make sure that the electrical breaker for the pool heat pump is in the FF position.
> Be Ensure the water lines and the heat pump are reconnected and/or drain valves are closed.
> Clean the pool filter and make sure the water is flowing adequately through the pool return line (22.5 – 70 PM).
> Complete your normal preparation and/or cleaning of the pool for the start of the season.
> Switch N the breaker for the electrical supply to the heat pump.
> Then you need only start the unit and adjust the temperature to the desired value.
End of season (Winterizing)
> Switch FF the breaker for the electrical supply to the heat pump.
> You must empty the unit of all water. You simply disconnect the WATER INLET and WATER UTLET lines by unscrewing
the two union fittings on the front of the unit. To completely remove the water from the heat exchanger, you must remove
the drain cap (WINTERIZING DRAIN) that is located on the side of the unit. You must then let the water flow out until the unit
is completely emptied. (See the illustration below.)
It is recommended to cover the heat pump with a protective cover that is available from your dealer.

POOL HEAT PUMP INSTALLATION
Determining ptimum Location
Choose a location where the noise of the heat pump, when running, and the discharged air will not disturb the neighbours.
Install the Pool Heat Pump Heater unit on a flat, stable surface that can support its weight and does not generate any un-
necessary noise and vibration.
Clearance
Choosing the location of your heat pump is very important. You should install it as close as possible to the filter system.
You should obey the clearance distances around the heat pump that are given in the drawing below.
Level Placement
We recommend that you install your heat pump on a solid base, for example two concrete tiles. Four (4) rubber pads (ab-
sorbent pads) are provided to lessen the transfer of vibrations. (See drawing below.)

Condensation and Drainage
The evaporator coil will produce condensation while the unit is running and drain at a steady rate, usually three to five
gallons per hour, depending on the ambient air temperature and humidity.
It is normal for condensation to drip out the C NDENSATI N WATER DRAIN PIPE that is located on the side of the unit.

POOL HEAT PUMP INSTALLATION
Water flow
To minimize heating time, make sure all water valves are open completely, that the water level of the pool is at the
correct height. The DPL Pool Heat Pump is designed to operate at full flow through the heat exchanger (condenser).
A flow rate of 22.5-70 gallons per minute ( PM) should be maintained.
Caution:
Either no flow or a low flow rate will cause the unit to shut down. The Pool Heat Pump will not operate without a flow of water.
Electrical connections
This includes the heat pump, swimming pool metal panels, light, heat pump, filter, chlorine generator, as well as any other
metal component or electrical equipment.
Some older swimming pools might not have an electrical connector cable. In such cases, you must drive a 3 to 4 ft (0.91 to
1.2 meters) copper rod into the ground next to the equipment.
The ground connector of the DPL heat pump is located on the side of the unit.
(See drawing below.)
Warning:
Your warranty may be voided if the equipment is improperly connected.

PLUMBING SPECIFICATIONS
Factory connections are for a 1 1/2" union nut.
Join the Pool Heat Pump inlet and outlet with rigid PVC (schedule 40). All joints must be glued with PVC glue. If rigid pipe
is not available, you can use soft or flexible piping with stainless steel clamps.
When the piping installation is completed, start the pool pump and check the system for leaks.
Check valve & Chemical trap loop
Ensure that the check valve and chemical trap loop are installed as shown above. The loop should be at least 8 inches
above the top of the chlorinator/feeder to prevent chlorine backup into the heater when the water pump is off. Install a
check-valve on the heater side of the loop to to prevent chlorine damage.
Flow rate
The DPL Pool Heat Pump is designed to handle the full flow from the pool pump. No bypass is required if the flow is in the
30 to 70 gallon per minute range.
Warning:
Flow rates exceeding 70 PM may damage the unit and compromise its efficiency.
External Bypass
ood practice also suggests considering the use of an external bypass on the inlet and outlet to enable the pool owner
to bypass the pool heater if service or maintenance is required.
