3. Installation and Connection

3.1 Heat Pump Location

The unit will perform well in any outdoor location provided that the following three factors are presented:

1. Fresh Air - 2. Electricity - 3. Pool lter piping

The unit may be installed virtually anywhere outdoors. For indoor pools please consult the supplier. Unlike a gas heater, it has no draft or pilot light problem in a windy area.

DO NOT place the unit in an enclosed area with a limited air volume, where the units discharge air will be re-circulated.

DO NOT place the unit to shrubs which can block air inlet. These locations deny the unit of a

continuous source of fresh air which reduces its efciency and may prevent adequate heat

delivery.

3.2 How Close To Your Pool?

Normally, the pool heat pump is installed within 7.5 meters of the pool. The longer the distance from the pool, the greater the heat loss from the piping. For the most part ,the piping is buried. Therefore, the heat loss is minimal for runs of up to15 meters(15 meters to and from the pump = 30 meters total), unless the ground is wet or the water table is high. A very rough estimate of heat loss per 30 meters is 0.6 kW-hour,(2000BTU) for every 5°C difference in temperature between the pool water and the ground surrounding the pipe, which translates to about 3% to 5% increase in run time.

3.3 Installation illustration

Remarks:

The factory only provides the heat pump. Other parts, including a contingent by-pass are to be provided by the user or installer.

Attention:

Please take the following steps when installing the heat pump:

1. Each addition of chemicals has to be performed through the conduits located AFTER the heat pump.

2. Install a by-pass for easy maintenance

3. Always place the heat pump on a solid base and use the supplied silent blocks in order to avoid vibrations and noise.

4. Always keep the heat pump in upright position. If the unit has been tilted, you should wait for at least 24 hours before turning it on.

3.4 Installation of a check valve

When using automatic chlorine and pH dosage systems, it is of uttermost importance to protect the heat pump from high concentrations of these chemicals that could corrode the heat exchanger Therefore, such systems should add the chemicals in the conduits located DOWNSTREAM of the

heat pump and it is recommended to install a check-valve in order to prevent backow when there

is no water circulation. Damage to the heat pump caused by disregarding any of these recommendations will invalidate the warranty.

10

3.5 Electrical Wiring

Important - Although the heat pump is electrically isolated from the rest of the unit, this only prevents the passage of electricity to or from the pool water. Grounding the unit is still required to protect yourself from short circuits inside the unit. Make for adequate ground

connection.

Check if the electrical mains voltage corresponds with the operating voltage of the heat pump prior to hooking up the unit. It is recommended to use a separate fuse (C-curve) as well as adequate wiring (see table below). Connect the electrical wires with the terminal block labelled ‘TO POWER SUPPLY’.

Next to this connection, there is a second terminal block labelled ‘TO PUMP’, to which the lter pump (max. 5A/240V) or an electrical relay for a ltration pump can be connected. This connection makes it possible to control lter pump operation with the heat pump.

3.6 Initial startup of the Unit

NOTE- In order for the unit to heat the pool or spa, the lter pump must be running to

circulate water through the heat exchanger.

Start up Procedure - After installation is completed, you should follow these steps:

1. Turn on your lter pump. Check for water leaks and verify ow to and from the pool.

2. Turn on the electrical power supply to the heatpump, then press the key ON/OFF of wire con-

troller, It should start in several seconds.

3. After running a few minutes make sure the air leaving the fan opening of the unit is cooler (between 5-10°C)

4. With the unit operating turn the lter pump off. The unit should also turn off automatically,

5. Allow the unit and pool pump to run 24 hours per day until desired pool water temperature is reached. When the desired pool water temperature reaches the setting, the unit just shuts off. The unit will now automatically restart (as long as your lter pump is running) when the pool temperature drops more than 2°C below set temperature.

Time Delay- The unit is equipped with a 3 minute built-in solid state restart delay included to protect control circuit components and to eliminate restart cycling and contactor chatter. This time delay will automatically restart the unit approximately 3 minutes after each control circuit interruption. Even a brief power interruption will activate the solid state 3 minute restart delay and prevent the unit from starting until the 5 minute countdown is completed. Power interruptions during the delay period will have no effect on the 3 minute countdown.

3.7 Condensation

Since the Heat pump cools down the air about 5°C, water may condense on the ns of the evaporator. If the relative humidity is very high, this could be as much as several liters an hour. The

water will run down the ns into the base pan and drain out through the barbed plastic condensation drain tting on the side of the base pan. This tting is designed to accept 20mm clear vinyl tubing which can be pushed on by hand

and run to a suitable drain. It is easy to mistake the condensation for a water leak inside the unit.

TIP: A quick way to verify that the water is condensation is to shut off the unit and keep the pool pump running. If the water stops running out of the base pan, it is condensation. AN EVEN QUICKER WAY IS TO TEST THE DRAIN WATER FOR CHLORINE - if there is no chlorine present, then it’s condensation.

6. Maintenance and Inspection

• Check the water inlet and drainage often. The water and air inow into the system should be sufcient so that its performance and reliability does not get compromised. You should clean the pool lter regularly to avoid damage to the unit caused by clogging of the lter.

• The area around the unit should be spacious and well ventilated. Clean the sides of the heat pump regularly to maintain good heat exchange and to save energy.

• Check if all processes in the unit are operational and pay special attention to the operation pressure of the refrigerant system.

• Check the power supply and cable connections regularly. Should the unit begin to function abnormally or should you notice a smell from an electrical component, arrange for timely repair or replacement.

• Winterizing : make sure to purge all the water from the heat pump and other systems in order to

prevent frost damage.

• You should also purge the water if the unit will not work for an extended period of time. You should check all parts of the unit thoroughly and completely ll the system with water before turning it on again afterwards.
