INSTALLATION & OPERATION MANUAL
BEFORE YOU BEGIN
1Ensure that the heat pump arrives in good condition upon delivery.
2 Adequate airflow around the heat pump is vital, ensure that the surroundings are kept clear of
debris, tree branches and anything that might impact the ventilation of the unit. Refer to Section 3.2
of this manual for more information.
3Register your unit’s warranty details and upload your invoice online at:
www.guardianpoolheating.com.au/
4 Your unit should be installed in an outdoor area for maximum performance, for indoor installations
contact Guardian for guidance.
5Check the condensate drain of the heat pump regularly to avoid blockages or debris build up.
Keeping it in good order ensures condensation easily drains from the unit.
6 When using Wi-Fi control, ensure that you have full Wi-Fi strength available where the heat pump is
installed. You will require a 2.4gHZ connection to use the Wi-Fi Controller App.

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.
