MAINTENANCE INSTRUCTIONS
This operation must be obligatorily carried out by a professionally qualified person. It should be
carried out at least once a year and includes several elements:
o Cleaning of the rear evaporator with the aid of a thin brush and a nondirty and
nonchlorinated water spray.
o Revision of instructions and operating issues of the unit.
o Revision of the safety mechanisms.
o Dusting the circuit board.
o Checking the earth connections.
o Checking the gas pressure.
PREVENTIVE MAINTENANCE.
A record should be kept of each element repaired or substituted as well as of all maintenance
and repairs.
The surface of the exterior panels may be cleaned with a soft cloth and non-abrasive cleaner.
DISCONNECT THE EQUIPMENT FROM THE POWER SUPPLY before performing any
maintenance procedures.
TO KEEP IN MIND:
EVAPORATOR COIL:
The evaporator coil should be kept clean and free of obstacles which may hinder the
circulation of air through them. In order to clean it, use water (little pressure) and non-
abrasive detergents or cleaning liquids made specifically for it.
COMPRESSOR:
Compressor oil must be checked in those unit models provided with an oil viewer.
Verify that the compressor refrigerates adequately with the circulating gas (verify the
refrigerant charge).
Verify that the power consumption has not increased.
Verify that the compressor discharge pressure is not too high and that the intake pressure is
not too low.
Verify that the compressor fasteners are not deteriorated.
Verify that no frost develops on the compressor.
CONDENSER COIL:
The condenser coil should be kept clean and free of obstacles which may hinder the
circulation of air through them. In order to clean it, use water (little pressure) and non-
abrasive detergents or cleaning liquids made specifically for it.
FAN:
Verify the flows of the fan each year.
Clean the louvers of the fan as well as the protection grill regularly.
ELECTRICAL PANEL:
Verify all electrical connections.
Verify that there is no over-heating of the electrical terminals.
Verify that the protection systems operate correctly.
Verify that the regulator operates correctly and verify the temperature with a mercury
thermometer (calibration probe).
