1. Always keep the unit upright. If the unit has been tilted or put on its side, wait 24h before starting the heat pump.
2.  Put the unit on a fl at, solid base. Tilting the heat pump for max 3° is accepted.
3. Do not drop the heat pump.
4.  The heat pump must always be installed outdoors.
5. Check if the voltage indicated on the heat pump corresponds to the local mains voltage before you connect the unit. Please fi nd more information about the electrical connection in section 4.4
6.  Do not pull any electrical cable, sensor or tubing with unnecessary force.
7. Do not wrap any cable around the heat pump.
8. Do not use the heat pump in combination with a transformer.
9.  If the heat pump is damaged during transportation, it must be replaced, please contact your service centre or similarly qualified persons in order to avoid a hazard.
10.  Always make sure the water connections of the heat pump are properly locked before you start using the machine.
11.  Never insert objects directly into the fan, as this will cause it to become blocked and damaged.
12. The evaporator fi ns must not be damaged.
13.  This heat pump is not intended for use by persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the heat pump by a person responsible for their safety.
14. Children should always be supervised to ensure that they do not play with the heat pump.
15.  Disconnect electricity when the heat pump is not in use and before cleaning.
16.  The heat pump should be serviced only by a qualified service person. Contact your nearest authorized service facility for examination, repair or adjustment.
17. If the supply cord is damaged, it must be replaced by the manufacturer or your service agent or similarly qualified person in order to avoid a hazard.
18. Please contact your dealer if your swimming pool heat pump is not working properly. There might be a leakage when the heat pump does not heat the swimming pool water. The R32 refrigerant gas is safe when there is a leakage although fi re can occure when a flame, heating device or stove gets in contact with the gas. Stop using your swimming pool heat pump until a qualified service technician has confirmed that the leak has been repaired.
19.  Make sure that there is a circuit breaker for the unit, lack of a circuit breaker can lead to electrical shock or fi re.
20. The heat pump is equipped with an over-load protection system. It does not allow for the unit to start for at least 3 minutes from a previous stoppage.
21. The condense water is not suitable for a potable water connection.

Preparing the heat pump for use

Typical set-up4.1 Typical set-up

The factory provides the heat pump and connection kit. Other parts, including a contingent by-pass must be provided by the user or installer. The heat pump should be located 2m (recommended) away from the swimming pool. The longer the distance from the pool, the greater the heat loss from the piping

• Put the heat pump on a flat, solid base. Tilting the heat pump for max 3° is allowed. Install silent blocks in order to avoid vibrations and noise.
• All feeding of water treatment to the pool water has to be done downstream of the heat pump(2).
• It is normal for condense water to come out of the heat pump. This is not a leak or fault with the unit. If the humidity is very high, the condense water could be a number of liters a day. Please fi nd more information about condensation in section 5.2.
• Always keep the heat pump in upright position. If the unit has been tilted, then wait 24h before starting the heat pump.
• It is recommended to install a by-pass for easy maintenance.

Water connection kit

The factory provides the water connecting kit. This kit consists of 6 parts, with part 1 and 2 as main parts. The parts 3 to 6 can be swapped so that the connection can be made according to the specific requirements of the pool. So in total there are 4 possible options for connecting the water pipes, as shown below.

 Installation of the tubing

The heat pump should be located 2m (recommended) away from the swimming pool. The longer the distance from the pool, the greater the heat loss from the piping. The piping to and from the heat pump need to fi t the chosen connections. The pipes can be glued, clamed or screwed onto these water connections and can be made out off hard or flexible PVC. Always install piping intended for swimming pool use and use the correct glue to put them together.
OUT – Water connection from heat pump:
Typical water pipe from heat pump to water treatment system.
IN – Water connection to heat pump:
Typical water pipe from filter system to heat pump.

Electrical wiring

Always check if the voltage from the network corresponds with the operating voltage of the unit. Your typical swimming pool configuration can be controlled using a timer. Please contact your service centre or similarly qualified persons to change the RCD into a standard electrical plug. A timer can be put in between the heat pump AND pool circulation pump once a standard electrical plug is installed. Using a timer; The heat pump and pool circulation pump will start up automatically as soon as power is broken and restored. The heat pump remembers its last status and starts up with last remembered settings.

• Although the heat pump is electrically isolated from the rest of the pool equipment, 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. Provide an adequate ground connection.
• Test the RCD before usage as follows:

1.  Plug the RCD into a fixed socket
2.  Press the “RESET” button. The indicator should be “ON”.
3. Press the “TEST” button. The indicator should be “OFF”.
4. Press the “RESET” button again to start using the heat pump

You should always switch off the heat pump immediately when the RCD indicator is turned “OFF”. Be extremely careful when pressing “RESET” after a failure because there might still be a problem.
The controller of the Sun Spring heat pump has a memory so that the settings are retained even if the power is switched off and on. This makes it possible to operate the heat pump with a timer. The timer must be installed between the heat pump and the RCD plug, see picture. The installation must be carried out by a certifi ed electrical installer in order to guarantee quality and safe operation.

 Be aware of

 Heat loss

The longer the distance from the pool, the greater the heat loss from the tubing. It is therefore recommended to place the pump as close to the pool as possible.

• Several days will be needed to bring the temperature of the swimming pool water to its desired water temperature, depending on the initial water temperature, ambient and pool volume.
• A good pool cover and insulation of the tubing to and from the swimming pool and heat pump can reduce the warming up time considerably.

Condensation

As the heat pump cools down the air about 10°C, water may condense on the fi 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 fi ns into the base pan and drain out through the hole at the bottom of the heat pump. Sometimes this condensation water is wrongly considered as swimming pool water. If desired the heat pump can be fitted with a clear vinyl tube, to divert the condensation water away from the heat pump.
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.

• Check regularly that the drainage is not clogged and that no condensation water remains in the heat pump.

 Unobstructed space

A free area around the heat pump has to be kept clear from any object to get fresh air across the evaporator. Do not obstruct the fan.

Time delay of compressor

The heat pump is equipped with a 3 minute built-in solid state restart delay once the compressor is turned off and a 1 minute buit-in solid state compressor running time. Both to protect control circuit components, to eliminate restart cycling and contactor chatter. This time delay will automatically restart the unit approximately 3 minutes after each control circuit interruption or after a compressor running period of 1 minute. Even a brief power interruption will activate the solid state 3 minute restart delay and prevent the unit from starting until the 3 minute countdown is completed. Alarms or errors during time delay have no infl uence. Power interruptions during the delay period will cause a restart of time delay.

 Operation and Use

Maintenance and Inspection

• Check the water inlet and drainage often. The water and air infl ow into the system should be suffi cient so that its performance and reliability does not get compromised. You should clean the pool fi lter regularly to avoid damage to the unit caused by clogging of the fi lter.
• The area around the unit should be spacious and well ventilated as shown in section 5.3. 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.
•  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.
•  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 fi ll the system with water before turning it on again afterwards.

If your heat pump has been stored for a long time, perform the following steps when re-starting the system:

1.  Inspect the system for any debris or damage to the case.
2.  Clean the evaporator fi ns with a soft cloth if necessary. Make sure the evaporator fi ns are clean. Blocking the air intake will cause insuffi cient operation and will result in lower production of heat.
3. Check the fan for blockages.
4. Connect the water inlet and outlet.
5. Turn on the pool water circulation pump to start the water fl ow to the heat pump.
6. Restore electrical power to the heat pump and press the reset button on the RCD.
   

Water chemistry

Special care should be taken to keep the chemical balance of your swimming pool within following limits:

| Min.| Max.
---|---|---
pH| 7,0| 7,8
Free chlorine (mg/l)| 0,5| 1,5
Salt (g/l)| | 8

• Failure to keep the swimming pool water between the above mentioned limits will void the warranty.
• When the concentration of one or more products mentioned above becomes too high, irrevocable damage to your heat pump may occur. Make sure that you always install water treatment equipment after the heat pump. When an automatic chemical feeder is installed in the plumbing, it must be installed downstream of the heat pump.

Winterizing

Winterizing option 1 – Indoor storage
We recommend storing Sun Spring heat pumps in a garage or shed for winter. Perform the following actions to completely drain the heat pump:

• Turn off the electrical power to the heat pump at the main breaker panel.
•  Shut off the water supply to the heat pump.
