3. INSTALL & CONNECTION
3.1 INSTALLATION DIAGRAM
Note: Diagram is for reference only.
The Heat Pump can be installation can be configured with a bypass system to enable operation of the filtration and
sanitation systems to continue while the heat pump is not in use.
Upon receiving your unit you will also receive 1x Instruction Manual, 2x Connectors, 2x Rubber Rings & 4x Rubber Feet.
When using the unit for the first time:
•Open the water valves.
•Make sure that the pump and the water-in pipe have been filled with water.
•Close the valve and start the unit.
Note: It is necessary that the water-in pipe is higher than the pool’s surface.
3.2 LOCATION OF INSTALLATION
Note: as per the diagram, you need to have clearances of: 700mm at the front,
300mm at the rear, 1500mm at the top of the unit, and 700mm on both sides.
DO NOT place the unit in an enclosed area or room to prevent the discharge air
being recirculated.
DO NOT place the unit near shrubs that may grow and block the air inlet.
Placing the unit in a location where the unit is denied a continuous source of
fresh air will reduce efficiency and may prevent adequate heat delivery.
The heat pump should be installed as close as possible to filtration equipment. The longer the distance from the pool, the
greater the heat loss from the piping.
Majority of the piping is usually buried, therefore the heat loss is minimal for runs of up to 15 metres (each way, 30 in
total) unless the ground is wet or the water table is high. A very rough estimate of heat loss per 30 metres is 0.6kW an
hour for every 5˚C difference in temperature between the pool water and the ground surrounding the pipe, translating to
roughly 3% to 5% increase in run time.
3.3 PLUMBING OF THE UNIT
The titanium heat exchanger of the unit requires no special plumbing
arrangements. The water pressure drop is less than 10kPa at maximum
flow rate. Since there is no residual heat or flame temperatures, the unit
doesn’t require copper heat sink piping. PVC pipe can be ran 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.

Page 7
LUX-V SERIES
INSTALLATION & OPERATION MANUAL
Standard models have slip glue fittings which accept 40mm or 50mm PCV pipe for connection to the pool or spa filtration
plumbing. By using a 50mm to 40mm reducer you can plumb 40mm.
CONDENSATION: Since the heat pump cools down the air from 4-5˚C, water may condense on the fins of the
evaporator. If the relative humidity is very high, this could be multiple litres per hour. The water will run down the fins
into the basepan and drain our 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 ran to a suitable drain. It is very
easy to mistake the condensation for a leak inside the unit.
NB: A quick way to determine if the water is condensation is to shut off the unit while keeping the pool pump running. If
water stops running out of the basepan then it is condensation. Another way is to test the drain water for chlorine, if
there is no chlorine present then it is condensation.
3.4 ELECTRICAL WIRING
Note: Although the unit’s 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 the electrical hookup,
connect the heat pump by electrical conduit, UF cable or another 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 or residential air conditioners and heat pumps. It
prevents remotely-energising unattended equipment and permits turning off power at the unit while it is being serviced.
3.5 FIRST TIME STARTUP
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.
STARTUP PROCEDURE
(After installation has been completed follow these steps)
1. Turn on the 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 ON/OFF key on the controller. The unit should
start within a few seconds.
3. After running for a few minutes ensure the air leaving the unit is cooler (between 5-10˚C)
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 24hrs per day until the desired water temperature is reached at which point
the compressor will slow down to maintain temperature.
TIME DELAY
The heat pump is equipped with a time delay, this prevents the unit from short cycling. The fan will always start first,
followed by the compressor.

Troubleshooting:
Ensure that you are connecting to a 2.4GHZ network, not a 5GHZ network. If you are unsure, contact your network
provider.
Ensure you are not connecting to a Wi-Fi booster or extender, connection must be made to the modem directly.
Check signal strength and distance between the heater and the modem is not more than 10m. If possible, try moving your
modem closer to test the connection.
(If issues occur) Try using a different mobile device with a different software version to ensure you have no compatibility
issues.
5.2 INSTALLATION
There is a magnet on the back on the wi-fi module which holds it in place on the heat pump. Where possible, the module
should be placed on the unit in a location where it receives the least direct sunlight and away from other weather
elements.

6. MAINTENANCE & INSPECTION
Check that the heat pump has good water flow. Avoid the condition of no water or air entering the system, 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 or 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.
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 a qualified technician.
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 minimised. For repair to the refrigerating system, the following precautions shall be complied with prior
to conducting work on the system.
WORK PROCEDURE
Work shall be undertaken under a controlled procedure to minimise the risk of a flammable gas or vapour being present
while the work is being performed.
GENERAL WORK AREA
All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out.
Work in confined spaces should be avoided. The area around the workspace should be sectioned off. Ensure that the
conditions within the area have been made safe by control of flammable material.
CHECKING FOR PRESENCE OF REFRIGERANT
The area should be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is
aware of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use
with flammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
PRESENCE OF FIRE EXTINGUISHER
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 area.
NO IGNITION SOURCES
No person carrying out work in relation to a refrigeration system which 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, repairing, removing 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 during the period that the work is carried out. The ventilation should
safely disperse any released refrigerant and preferably expel it externally into the atmosphere.
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.
