17. TROUBLESHOOTING GUIDE

The reasons why your Air-Water EF cooler may not function properly are mentioned below:
THE UNIT DOES NOT START:
Maneuver switch opened: Ensure that no short circuit in the maneuver box is present, repairing if
there was.
Coil contactor does not activate: Verify that it is not burned, and replace it if it is. Verify the
terminals which activate the coil.
Internal thermal switch tripped: Verify the voltage of the line. Verify that the operating
conditions are correct. Excessive compressor consumption. Short circuit in the compressor.
Low pressure switch tripped: Verify the switch operates correctly, replacing it if necessary.
Verify that the fan is operating correctly. Verify the refrigerant charge of the equipment
(refrigerant leak, loss of refrigerant fluids) in order to solve this problem; please refer to the
refrigerant charge section.
Verify that there is sufficient ventilation around coils. Verify that there are no obstructions in the
cooling circuit and eliminate them if there are. Verify that the thermostatic valve works properly
and replace them if necessary.
High pressure switch tripped: Verify that the pressure switch operates correctly and substitute if
necessary. Check the refrigerant charge (excess refrigerant) in order to solve this please refer to the
refrigerant charge section. Check for any obstruction of the cooling circuit and eliminate the
obstruction if necessary. Check that the water flows through and that cleaning pump works.
Verify that there is sufficient water around the condensers.
Low flow alarm: Check the proper work of the treatment plant pump (which could not provide the
required flow). The filter of the treatment plant pump is dirty; in such case proceed to cleaning.
The By-Pass valves are closed or not open enough, then proceed checking. The pump is not
cleaning, check the status of timing clock and cleaning mode. The flow control needs repair (notify
the service).
Defrost cycle: The ambient conditions are not correct (temperatures are too low). The machine
will not operate under these conditions so turn off the machine.
LOW OIL LEVEL:
Oil stains on the equipment: Check for leaks in the cooling circuit and repair them if necessary,
check the torque on the high and low mini pressure switches, and replace them if necessary.
THE EQUIPMENT OPERATES ON CYCLES WHICH ARE TOO SHORT:
