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
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,
(Electrotechnic Regulations for Low Voltage, Supplementary Technical Instructions, Low Voltage,
· The electrical and hydraulic connections must be made according to the applicable regulations
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

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.
·
