When the unit is configured to heat Pool and Spa water, we can use both terminals, EXT #1 and
EXT #2, to gain some extra capabilities (first SPA Control screen on technical menu has to be set
to External control, see 5.7. 17).
EXT #1 EXT #2 RESULT:
The unit will work on Pool mode.
The unit will work on Spa mode
The unit will work on Pool + Spa mode
External Stop (same case as in general mode)

START START UP PROCEDURE FOR THE UNIT UP PROCEDURE FOR THE UNIT
Operating requirements for the heat pump:
The outdoor temperature must be higher than +5 ºC.
•
The heat pump is provided with a defrost thermostat that guarantees compressor
•
shutdown and the operation of the defrost system.
When washing the filter of the filtering pump, it is MANDATORY to turn off the heat
•
pump.
Before any start-up, you should check:
The correct clamping of the hydraulic connections (exchanger inlet / outlet).
•
The correct fastening of the electrical cables to the connection terminals. Poorly
•
secured terminals can cause the terminal block to heat up.
When setting-up, the electrical connections, as well as the general power supply and
•
voltage should be verified.
Once the unit is connected, verify the intensity absorbed by the phases and check that
•
the fan is operating in the correct direction.
Give power to the equipment by connecting the general power switch on the outside of
•
the unit. Once the unit is connected, verify the intensity absorbed by the phases.
Three-phase units have a phase control relay that guarantees the compressor is
•
operating in the correct direction. If the controller shows the compressor it is running
and it does not, phases must be interchanged. Card gives an alarm signal.
With the machine running, verify the intensities absorbed by the electric motors,
•
making sure they do not exceed the limits mentioned in the technical specification
sheet.
Verify that the currents of the different lines are not out of phase except in the case of
•
single-phase circuits.
High and low pressure switches should be installed in the cooling circuit and verify the
•
refrigerant charge (Refrigerant Charge section).
