1.3 Water treatment
Poolex heat pumps for swimming pools can be used with all types of water treatment systems.
Nevertheless, it is essential that the treatment system (chlorine, pH, bromine and/or salt chlorina-
tor metering pumps) is installed after the heat pump in the hydraulic circuit.
To avoid any deterioration to the heat pump, the water’s pH must be maintained between
6.9 and 8.0.
1. General
During use
To avoid serious injuries, never touch the fan when it is operating.
Keep the heat pump out of the reach of children to avoid serious injuries caused by the heat
exchanger’s blades.
Never start the equipment if there is no water in the pool or if the circulating pump is stopped.
Check the water ow rate every month and clean the lter if necessary.
During cleaning
Switch o󰀨 the equipment’s electricity supply.
Close the water inlet and outlet valves.
Do not insert anything into the air or water intakes or outlets.
Do not rinse the equipment with water.
During repairs
Carry out work on the refrigerant system in accordance with current safety regulations.
Brazing should be performed by a qualied welder.
When replacing a defective refrigerant component, use only parts certied by our technical
department.
When replacing pipework, only copper pipes conforming to Standard NF EN12735-1 may be used
for repairs.
When pressure-testing to detect leaks:
To avoid the risks of re or explosion, never use oxygen or dry air.
Use dehydrated nitrogen or a mixture of nitrogen and refrigerant.
The low and high side test pressure must not exceed 42 bar.
