Operation; Troubleshooting - Pahlen Aqua compact User Manual

Electric heater Aqua compact
Start
1. Fill water in the pool to the correct level.
2. Start the pump for the pool water circulation.
3. Check that the water circulates normally in the system and that all air is drained from the system.
The heater must be completely water-filled before switching on the power. The heater can only be switched on when all air is
drained out of the system.
4. Test the function of the heater by turning the thermostat dial back and forth and check that the thermostat's contactor
switches on and off.
The flow monitor is controlled by switching off the flow through the heater with a shut-off valve and checking that the
contactors switch off. Switch on the water again. The contactors should then turn on again.
5. Set the desired pool temperature with the thermostat knob.
6. The water is now heated to the desired temperature.

Operation

When backwashing and cleaning the filter, switch off the power of the heater. If there is a risk of freezing, the power must be
switched off and the heater must be emptied of all water.

Troubleshooting

1. Check the fuses.
2. Check that the system has the required flow through the heater.
3. For safety reasons, the heater's overheating protection is triggered in the absence of water or poor circulation. This is the
most common reason why the heater has "stopped working". Check if the overheating protection has tripped and investigate
the cause. After the cause has been clarified and rectified, the overheating protection is restored by:
- Unscrewing the protective cap (A).
- Pressing the reset button (B) on the junction box.
- Put the cover back on.
4. Checking the heater function, see item 4 under "Start".
5. Adjusting the thermostat to a higher temperature.
6. If the problem persists: contact the installer.
