1.3 Water treatment
Poolex heat pumps for swimming pools can be used with all types of water treatment systems.
Nevertheless, it is essenal that the treatment system (chlorine, pH, bromine and/or salt chlorinator metering
pumps) is installed aer the heat pump in the hydraulic circuit.
To avoid any deterioraon to the heat pump, the water’s pH must be maintained between 6.9 and 8.0.
1. GENERAL INFORMATION
When in use
Do not touch the vent during operaon due to the risk of serious injury.
Do not leave the heat pump within reach of children due to the risk of injury caused by the heat exchanger ns.
Never start the equipment if there is no water in the pool or if the circulang pump is stopped.
Check the water ow rate every month and clean the lter if necessary.
When cleaning
1. Switch o the power supply to the device.
2. Close the water inlet and outlet valves.
3. Do not place anything in the openings of the water or air inlets/outlets.
4. Do not spray the appliance with excessive amounts of water.
During repairs
Carry out work on the refrigerant system in accordance with current safety regulaons.
Brazing should be performed by a qualied welder.
When replacing a defecve refrigerant component, use only parts cered by our technical department.
When replacing pipework, only copper pipes conforming to Standard NF EN12735-1 may be used for repairs.
When pressure-tesng to detect leaks:
• Use dehydrated nitrogen or a mixture of nitrogen and refrigerant.
• To avoid the risks of re or explosion, never use oxygen or dry air.
The low and high side test pressure must not exceed 42 bar.
1.4 Operating limits
Your heat pump’s performance is at its opmal when outside temperature is between -10 °C and 43 °C.
When outside temperature is below -10 °C, the heat pump is useful to maintain the temperature within the
hot tub. However, it is not suitable to heat up your hot tub alone when outside temperature is below -10 °C. As
such, it is recommended to use it with the SPA heater control relay (see § 3.6) during the cold season.
Your hot tub must be correctly insulated to enable the heat pump to funcon in an opmal way.
• The tub must be insulated.
• The piping must be insulated.
• The hot tub must be equipped with an insulang cover.
