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 efciency and may prevent adequate heat delivery. 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.

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: Each addition of chemicals has to be performed through the conduits located AFTER the heat pump. Install a by-pass for easy maintenance Always place the heat pump on a solid base and use the supplied silent blocks in order to avoid vibrations and noise. 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. 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 labeled 'TO POWER SUPPLY'. Next to this connection, there is a second terminal block labeled '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. However, we do not recommend that you wire the pool circulation pump to the heat pump.Run separate power supplies to the heat pump and the pool circulation pump. This allows the pool circulation pump to be put on a time clock and operated for the required time to give adequate ltration for the pool and also the pool circulation pump can be manually operated when required to backwash the lter etc.

*Minimal fuse 3.6 Initial start-up 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: Turn on your lter pump. Check for water leaks and verify ow to and from the pool. Turn on the electrical power supply to the heat pump, then press the key ON/OFF of wire controller, It should start in several seconds. After running a few minutes make sure the air leaving the fan opening of the unit is cooler (between 5-10°C) With the unit operating turn the lter pump off. The unit should also turn off automatically, 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.
