5. START-UP PROCEDURE FOR THE UNIT
Operating requirements for the heat pump
1. The outdoor temperature must be higher than +5 ºC.
2. The heat pump is provided with a defrost thermostat that guarantees the compressor shutdown and the
operation of the defrost system.
3. When washing the filter of the filtering pump, it is OBLIGATORY that the heat pump is turned off.
Performing the heat pump adjustments in its initial operation
1. The correct clamping of the hydraulic connections (exchanger inlet / outlet).
2. The correct fastening of the electrical cables to the connection terminals. Poorly secured terminals can cause
the terminal block to heat up.
3. When setting-up, the electrical connections, as well as the general power supply and voltage should be verified.
4. Once the machine is connected check the intensity absorbed and check that the fan is operating in the correct
direction, and if not, invert the phases.
5. Give power to the equipment by connecting the general power switch on the outside of the machine. Once the
machine is connected, verify the intensity absorbed by the phases.
6. In case of III machine, compressor rotation sense must be checked. If the controller indicates that the
compressor is running and it is not, phases must be exchanged.
7. With the machine running, verify the intensities absorbed by the resistors and electric motors, making sure they
do not exceed the limits mentioned in the technical specification sheet.
8. Check that there is not phase shift between non II (two phases) lines.
9. High and low pressure switches should be installed in the cooling circuit and verify the refrigerant charge
(Refrigerant Charge section).
Performing the heat pump adjustments in its initial operation
1. Start filtering in order to circulate the swimming pool water inside the heat pump exchanger. It is essential that
the filtering equipment starts before the heat pump.
2. Switch the heat pump on. Turn on the magnetic circuit breaker.
3. Set the temperature you prefer (5.E. Description and operation of the controller).
4. The installing technician must adjust the valves of the by-pass according to the pressures of the machine and
must refrain from intervening anymore during the warming-up period.
IMPORTANT
The heat pump should always operate together with the purification pump. We must have the precaution never
to interconnect timers or programmers which may stop the purification pump and leave the unit working alone.
The heat pump will take several days to reach the requested temperature: this is completely normal.
