B. Wiring
1) Connect the power cable to a suitable power source, voltage should correspond to the nominal voltage of the pump.
2) The heat pump must be properly earthed.
3) The heat pump should only be wired in by a qualified professional referring to the wiring diagram provided. .
4) Regulate the leakage current of the differential circuit breaker with respect to the regulations in effect in the country of installation.
(Leakage current ≤ 30mA in France).
5) Cables should be run in an orderly fashion, they should not touch off each other.
C. Once wiring is complete and checked, switch the heat pump on.
1. Hydraulic connections
Circulation of water through the heat pump is generally driven by the pool's filtration pump. To plumb it in, create a bypass loop on
the filtration circuit and fit it with 3 valves :
 An adjustable valve, located between the outlet and return branch of the bypass loop: this valve allows adjustment of the flow
through the heat pump in order to obtain the recommended flow rate (see the selection guide) ;
 A valve on the heat pump inlet pipe.
 A valve on the heat pump outlet pipe.
The last two valves are usually open, they should only be closed for interventions on the hydraulic circuit or to dismantle the heat
pump.
The by-pass loop should be located downstream from the filter to minimise the build up of dirt in the heat exchanger, but upstream
from the injection of disinfection or pH adjusting chemicals (allow a distance of at least 1.5 m of pipe) to minimise the risk of
corrosion of the heat exchanger. The injection of treatment chemicals should be slaved to filtration. Ensure that the installation
configuration will not allow accidental siphoning from the treatment chemical tanks while filtration is not running.
Be careful not to allow impurities (stones, earth, etc.) to enter the pipes. These could clog the heat exchanger upon start up.
Two screw type adapter unions can be found on one side of the heat pump, these allow entry and exit of the pool water (marked).
The water inlet and outlet pipes should be glued to these unions. allow the glued unions to cure thoroughly before allowing water
into the circuit.
