The R-407C may cause freezing if it comes into contact with the skin, due to its immediate
evaporation.
As with all hydrocarbons, whether they are halogenated or not, the R-407C gas may, although it
has a very low level of toxicity, cause anaesthetic or preanaesthetic conditions if inhaled deeply
and within a closed area.

The reasons why your heat pump may not function properly are mentioned below:
• The unit does not start: The unit does not start:
The unit does not start: The unit does not start:
Operating switch tripped: Check there is no short circuit in the control panel, repair the
o
possible short circuit.
Coil contactor does not activate: Verify that it is not burned, and replace it if it is. Verify the
o
terminals which activate the coil.
Thermal switch tripped: Verify the voltage of the line. Verify that the operating conditions
o
are correct. Excessive compressor consumption. Short circuit in the compressor.
Low pressure switch tripped: Verify that the pressure switch operates correctly and
o
substitute 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. Check for any obstruction of the cooling
o
circuit and eliminate the obstruction if necessary. Verify that the thermostatic valve is
operating properly, checking the bulb has no gas leaks and that the pressure inlet is free of
obstruction. Replace if needed.
High pressure switch tripped: Verify that the pressure switch operates correctly and
o
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. Verify there is a good water flow through
the condenser, checking there are no obstructions in the hydraulic circuit, the shut-off valves
are open and the purification pump operates properly (replace if needed).
Flow alarm: Verify the purification pump is operating properly (pump flow may be less than
o
needed). The filter of the purification pump is dirty. Clean it if needed. By-pass are closed or
not sufficiently open. Revise it if needed. The pump is not working. Revise clock condition
and purification mode. The flow switch is faulty (call for service).
Defrost cycle: The ambient conditions are not correct (temperatures are too low). The unit
o
does not work under these conditions. It is recommended to disconnect the unit.
• Low oil level: Low oil level: Low oil level: Low oil level:
Low initial oil charge: Refill up to needed level.
o
Oil stains on the equipment: Check for leaks in the cooling circuit and repair them if
o
necessary, check the torque on the high and low pressure valves, and replace them if
necessary.
• The equipment operates on cycles which are too short The equipment operates on cycles which are too short: : : :
The equipment operates on cycles which are too short The equipment operates on cycles which are too short
The low pressure switch opens then closes again: Verify the points mentioned in the "low
o
pressure switch tripped" section above.
Intermittent contact on machine control unit: Repair or replace the faulty electrical part.
o
Check the temperature indicator.
Make sure the equipment is not too large for the facilities.
o
• The equipment does not shut down: The equipment does not shut down:
The equipment does not shut down: The equipment does not shut down:
Verify that the thermostat functions properly, repairing or replacing it if necessary.
