TECHNICAL MANUAL. START-UP AND OPERATION
5. START-UP OF THE HEAT PUMP
A. Installation rules
It is necessary to determine the unit location according to certain criteria:
· The unit must be secured on a hard base (concrete or hard steel frame type) and must be protected from flood risks.
· The unit must be installed outside, far away from the sun's direct rays and any other heat source.
· A clear space around the unit of around 1 m at the front and a minimum of 0.5 m at the back and sides of the unit must
be left.
· The air caused by the helix must be directed away from the limits of the work environment (windows, doors...).
· The minimum distance between the heat pump and the rim of the swimming pool must be, at least, 3.5 m.
(Electrotechnic Regulations for Low Voltage, Supplementary Technical Instructions, Low Voltage, 31, ITC-BT-31).
· The electrical and hydraulic connections must be made according to the applicable regulations (NF C 15 100, EC 1364).
The ducting for the connections must be fixed.
B. Hydraulic connections
Connect the PVC 50/38 piping water inlets and outlets of the swimming pool to the heat pump inlet and outlet. The connection will
be performed through a by-pass over the filtering circuit of the swimming pool after the filter and before the water treatment.
The unit is provided with two D-50 PVC unions, two 50-40x1 1/2" PVC adaptor nipples and two NPT 1 1/2"-38 hose couplings. For
those setups fitted with D-50 pipes, it should be enough installing the unions (photo 1). For those setups fitted with D-38 pipes, the
adaptor nipples and D-38 hose couplings must be installed (photos 2 and 3)

Once the necessary fittings are installed, inlets and outlets are connected......................................
C. Electrical connection
· The power supply for the heat pump must come, preferably, from a sole circuit provided with standard-issue protection
components (see above: protection by a 30 mA differential) and a magnetic circuit breaker.
· The electrical installation must be carried out by a qualified professional (an electrician, for example) according to the
applicable laws and regulations of the target country.
· The heat pump circuit must be linked to a safety earth circuit levelled to the terminal block .
· The cables must be correctly installed so that they do not cause interferences (items in the lead boards).
· The heat pump may be connected to an earthed general-purpose power supply.
· Cable section: This section is indicative and must be verified and adapted according to the installation needs and
