INSTALLATION AND CONNECTION
3.1 Installation illustration
Installation items:
The factory only provides the main unit and the water unit; the other items in
the illustration are necessary to spare parts for the water system, which are
provided by users or the installer.
Attention:
Please follow these steps when using it for the first time
- Open the valve and charge the water.
- Make sure that the pump and the water-in pipe have been filled with water.
- Close the valve and start the unit.
ATTN: It is necessary that the water-in pipe is higher than the pool surface.
The schematic diagram is for reference only. Please check the water inlet/outlet label on the heat pump while plumbing installation.
The schematic diagram is for reference only. Please check the water inlet/outlet label on the heat pump while plumbing installation.
The controller is mounted on the wall
3.2 Swimming Pool Heat Pumps Location
The unit will perform well in any outdoor location provided that the following
three factors are presented:
- Fresh Air –
- Electricity –
- 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 unit’s discharge air will be re-circulated.
DO NOT place the unit on shrubs that can block the air inlet. These locations deny the unit a continuous source of fresh air which reduces its efficiency and may prevent adequate heat delivery.
3.3 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 differences in
temperature between the pool water and the ground surrounding the pipe, which
translates to about a 3% to 5% increase in run time.
3.4 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 Temperatures, 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 models have slip glue fittings that 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 the 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 liters 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.
3.5 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
phases). To complete electrical hookup, connect the 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 disconnecting means (the 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 the 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:
- Turn on your filter pump. Check for water leaks and verify flow to and from the pool.
- Turn on the electrical power supply to the unit, then press the key ON/OFF of the wired controller, It should start in several seconds.
- After running a few minutes make sure the air leaving the top(side) of the unit is cooler(Between 5-10 )
- With the unit operating turn the filter pump off. The unit should also turn off automatically,
- Allow the unit and pool pump to run 24 hours per day until the desired pool water temperature is reached. When the water-in temperature reaches this setting, the unit will slow down for a period of time, if the temperature is maintained for 45 minutes the unit will turn off. The unit will now automatically restart (as long as your pool pump is running)when the pool temperature drops more than 0.2 below the 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.

If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging -
No ignition sources
No person carrying out work in relation to a refrigeration system that involves exposing any pipe work that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repair, removal, and disposal, during which flammable refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. No Smoking signs shall be displayed. -
Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue uring the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere. prolonged period of no usage. -
Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system. the prolonged period of no usage. -
Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt consult the manufacturer’s technical department for assistance.
The following checks shall be applied to installations using flammable refrigerants:
The charge size is in accordance with the room size within which the refrigerant-containing parts are installed;
The ventilation machinery and outlets are operating adequately and are not obstructed;
If an indirect refrigerating circuit is being used, the secondary circuit shall be checked forthe presence of refrigerant;
Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;
Refrigeration pipes or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant- containing components unless the components are constructed of materials that are inherently resistant to being corroded or are suitably protected against being so corroded. -
Checks to electrical devices
Repair and maintenance of electrical components shall include initial safety checks and
component inspection procedures. If a fault exists that could compromise the safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the equipment so all parties are advised.
Initial safety checks shall include:
. That capacitors are discharged: this shall be done in a safe manner to avoid the possibility of sparking;
. That there no live electrical components and wiring are exposed while charging, recovering, or purging the system;
. That there is continuity of earth bonding. -
Repairs to sealed components
- During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection hall be located at the most critical point to warn of a potentially hazardous situation.
- Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected. This shall include damage to cables, an excessive number of connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.
-
Ensure that apparatus is mounted securely.
Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specifications.
NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components do not have to be isolated prior to
Repair to intrinsically safe components
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and currently permitted for the equipment in use.
Intrinsically safe components are the only types that can be worked on while living in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating. Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak. -
Cabling
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges, or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.
Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be used in the search for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used.
Leak detection methods
The following leak detection methods are deemed acceptable for systems containing flammable refrigerants.
Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity -
may not be adequate, or may need re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25 % maximum) is confirmed. Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work. If a leak is suspected, all naked flames shall be removed/ extinguished. If leakage of refrigerant is found which requires brazing, all of the refrigerants shall be recovered from the system, or isolated (by means of shut-off valves) in a part of the system remote from the leak. Oxygen-free nitrogen (OFN) shall then be purged through the system both before and during the brazing process.
-
Removal and evacuation
When breaking into the refrigerant circuit to make repairs or for any other purpose conventional procedures shall be used. However, it is important that best practice is followed since flammability is a consideration. The following procedure shall be adhered to:
. Remove refrigerant;
. Purge the circuit with inert gas;
. Evacuate;
. Purge again with inert gas; . Open the circuit by cutting or brazing. -
The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be “flushed” with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used for this task. Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to the atmosphere, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system. When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipe work are to take place. Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available. working on them. Labelling Equipment shall be labeled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.
-
Recovery
When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely.
When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge is available. All cylinders to be used are designated for the recovered refrigerant and labeled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure relief valves and associated shutoff valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs. The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of flammable refrigerants. In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check that t is in satisfactory working order, has been properly maintained, and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult the manufacturer if in doubt. The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and especially not in cylinders. If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the compressor to the suppliers. Only electric eating to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely. -

Charging procedures
In addition to conventional charging procedures, the following requirements shall be followed.
Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimize the amount of
refrigerant contained in them.
Cylinders shall be kept upright.
Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
Label the system when charging is complete (if not already).
