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. Adjust the flow so that the
arrow of this pressure gauge in the green zone. See IMAGE 1 (page 181).
If it is not possible to install the doser/chlorinator 25cm below water discharge of the heat
pump, a siphon should be installed. For additional security, a check valve should also be
installed to prevent the chemical product from returning to the pump when water circulation is
interrupted.
The unit is provided with two D-50 PVC unions.
There must be water flowing through the hydraulic connections when the unit is running.
Never place concentrated chemicals in the swimming pool skimmers.
A full-flow shut-off valve should be installed on each of the hydraulic elements in the
equipment, so that each of these may be isolated if needed (for filter cleaning, repairs,
substitutions, etc.) without the need to drain the circuit.
Anti-vibration dampers should be installed in the inlet and outlet of the machine, in order to
avoid vibrations which may cause cracks or breakage in the hydraulic connections.
In order to avoid possible breakage, do not force the PVC tubes connected to the water supply.

The power supply for the heat pump must be, preferably, from a sole circuit provided with
standard-issue protection components: protection by a 30 mA differential and a magnetic
circuit breaker. See IMAGE 2 (page 182)

applicable laws and regulations of the region country. applicable laws and regulations of the region 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 1-Phase 230 VAC 50Hz general-purpose power
supply.
All wiring should comply with local and national electric codes and should not be prone to
overheating and subsequent voltage failures.
The acceptable tolerance to voltage fluctuation is +/- 10% during operation.
Table 2 shows some indicative sections, which must be verified and adapted according to the
installation needs and conditions. See TABLE 2 (page 180).
PROCEDURE:
Connect the equipment following the wiring diagram included in this manual.
•
Place a U-curve thermal-magnetic circuit breaker in the general power connection to
•
protect the line in case of a short circuit.
Place a differential circuit breaker in the general power connection to protect the
•
equipment from possible grounding problems. The differential breaker should be
minimum 30 mA.
Before installing the connections, be sure to disconnect electricity.
•
Connect the power supply wires to the unit's input terminal.
•
Connect the grounding wire to its corresponding terminal.
•
Connect 9 and 10 terminals in parallel with the purification pump clock.
