63.INSTALLATION AND CONNECTION

3.2 Swimming Pool Heat Pumps 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 filter 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 it efficiency and may prevent adequate heat delivery.

3.3 How Close To Your Pool?

Normally, the pool heat pump is installed within 7.5 metres 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 ℃ difference in temperature between the pool water and the ground surrounding the pipe, which translates to about 3% to 5% increase in run time.Unit:mm/inch

Air inlet Air outlet 300/ 11.8300/ 11.8700/ 27.6700/27.6 500/ 19.73.4 Swimming Pool Heat Pumps Plumbing The Swimming Pool Heat Pumps exclusive rated flow titanium heat exchanger requires no special plumbing arrangements except bypass(please set the flow rate according to the nameplate). The water pressure drop is less than 10kPa at max. Flow rate. Since there is no residual heat or flame Tempera- tures, The unit does not need copper heat sink piping. PVC pipe can be run straight into the unit. Location: Connect the unit in the pool pump discharge (return) line downstream of all filter and pool pumps, and upstream of any chlorinators, ozonators or chemical pumps. Standard model have slip glue fittings which accept 32mm or 50 mm PVC pipe for connection to the pool or spa filtration piping. By using a 50 NB to 40NB you can plumb 40NB Give serious consideration to adding a quick coupler fitting at the unit inlet and outlet to allow easy draining of unit for winterizing and to provide easier access should servicing be required. Condensation: Since the Heat pump cools down the air about 4 -5℃, water may condense on the fins of the horseshoe shaped evaporator. If the relative humidity is very high, this could be as much as several litres an hour. The water will run down the fins into the basepan and drain out through the barbed plastic condensation drain fitting on the side of the basepan. This fitting 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. NB: 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 basepan, it is condensation. AN EVEN QUICKER WAY IS to TEST THE DRAIN WATER FOR CHLORINE - if the is no chlorine present, then it's condensation.

To pool PVC COUPLER RECOMMENDED(Provided) From pump CONDENSATION DRAIN BARB FTG3.5 Swimming Pool Heat Pumps Electrical Wiring NOTE: Although the unit heat exchanger is electrically isolated from the rest of the unit, it simply prevents the flow of electricity to or from the pool water. Grounding the unit is still required to protect you against short circuits inside the unit. Bonding is also required. The unit has a separate molded-in junction box with a standard electrical conduit nipple already in place. Just remove the screws and the front panel, feed your supply lines in through the conduit nipple and wire-nut the electric supply wires to the three connections already in the junction box (four connections if three phase). To complete electrical hookup, connect Heat Pump by electrical conduit, UF cable or other suitable means as specified (as permitted by local electrical authorities) to a dedicated AC power supply branch circuit equipped with the proper circuit breaker, disconnect or time delay fuse protection. Disconnect - A disconnect means (circuit breaker , fused or un-fused switch) should be located within sight of and readily accessible from the unit, This is common practice on commercial and residential air conditioners and heat pumps. It prevents remotely-energizing unattended equipment and permits turning off power at the unit while the unit is being serviced.

3.6 Initial startup of the Unit

NOTE- In order for the unit to heat the pool or spa, the filter 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 filter pump. Check for water leaks and verify flow to and from the pool.

2. Turn on the electrical power supply to the unit, then press the key ON/OFF of wire controller, It

should start in several seconds.

3. After running a few minutes make sure the air leaving the top(side) of the unit is cooler(Between 5-10

4. With the unit operating turn the filter 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 emperature is reached.

When the water-in temperature reach setting, The unit just shuts off. The unit will now automatically restart (as long as your pool pump is running)when the pool temperature drops more than 2℃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.

Press the“ ” or“ ” key,current set ptflashes When unit is operating, press either “ ” or “ ” and the current temperature set point flashes. Then press either “ ” or “ ” to increase or decrease the temperature set point. Pressing will cancel the change and return operation to the original temperature display mode. To save the new temperature set point, do not press a key for 5s and the displayed value will be saved and operation will return to temperature display mode. To view the outlet temperature while in the temperature display mode press and hold “ ” for 2s. The outlet temperature is temporarily displayed, and then the display is returned to temperature display mode.

4. USAGECheck the water supply device and the release often. You should avoid the condition of no water or

air entering into system, as this will influence unit's performance and reliability. You should clear the pool/spa filter regularly to avoid damage to the unit as a result of the dirty of clogged filter. The area around the unit should be dry, clean and well ventilated. Clean the side heating exchanger regularly to maintain good heat exchange as conserve energy . The operation pressure of the refrigerant system should only be serviced by a certified technician. Check the power supply and cable connection often.Should the unit begin to operate abnormally, switch it off and contact the qualified technician. Discharge all water in the water pump and water system ,so that freezing of the water in the pump or water system does not occur. You should discharge the water at the bottom of water pump if the unit will not be used for an extended period of time. You should check the unit thoroughly and fill the system with water fully before using it for the first time after a prolonged period of no usage.

The following winterization steps are important to prevent freeze damage. A HEAT PUMP DAMAGED BY FREEZING IS NOT COVERED UNDER THE MANUFACTURER’S WARRANTY. Set the heat pump in “OFF” mode. Remove power power to the heat pump. Drain the appliance of all its water:

int towards the ground and allow water to drain completely. leaner. Connect the exhaust side of the vacuum cleaner to the upper port (outlet) of the heat pump to push any remaining water that may be left inside. Do not reconnect the plumbing to the heat pump. Plug the water inlet and outlet to prevent intrusion of small animals or debris during winter. Do not wrap the heat pump with canvas or tarpaulin as some ca nvas can cause discoloration of the equipment. This can also trap moisture which can promote rusting of metal components.
