GENERAL INTERVENTIONS

Check of any refrigerant leaks (this must be done respecting the deadlines recommend-

ed by the current European regulations)

Check of the unit power supply voltage 

Check of the compressors' power supply voltage

Check of the fan power supply voltage if present

Check of the solenoid valves

Functioning and calibration check of the pressure switches, if and where present

Check and reading of the pressure/temperature probes

Check and possible replacement of the dehydrating fi lters

Check of compressors contactors

Check of fans contactors, where present

Exchanger coils cleaning (preferably from the inside to the outside)

Check and cleaning of shell and tube heat exchangers if necessary where present

(1)

Check of electric resistances of the heat exchangers

Check for rust and corrosion in components, paying particular attention to under pres-

sure containers. In this case replace them of intervene with specifi c products

General cleaning of the unit

Bleed the hydraulic circuit and the heat exchangers, the simultaneous presence of air 

and water reduces yield and can benefi t the arising of rust

INTERVENTIONS TO COOLING CIRCUIT Functioning at full load

Overheating temperature measurement

Subcooling temperature measurement

Exhaust gas temperature measurement

Fans absorption measurement

Compressors absorption measurement

COMPRESSOR CHECKS

Check oil level

Check oil acidity

Check the proper functioning of the casing resistance

Check oil level sensor, if any

CHECKS ON HYDRAULIC CIRCUIT

Pumps absorption measurement

Check the pump rotor gasket

Check the fl exible joints

Check the seal of the shell and tube heat exchanger heads, where present

Check the proper functioning and calibration of the fl ow switch, where present

Check the proper functioning of the diff erential pressure switch, where present

Check the concentration of glycol solution, if provided 

3 months*

Cleaning the water fi lter

The frequency of the operations described herein is a guideline one and they may vary depending on how the unit is used and the type of system 

where it is installed. However, if the unit is installed in harsh environments, we recommend reducing the time of intervention 

* To replace the glycol, refer to the documentation provided by the supplier.
