Flammable – risk of fire.

High voltage – risk of electric shock.

Toxic – risk of intoxication.

APPENDIX 1
SAFETY RECOMMENDATIONS FOR COMPRESSOR 
INSTALLATION

Failure to shut down the mains compressor during maintenance procedures and to apply 
a system without a ground fault circuit interrupter (GFCI) or residual current device (RCD), 
according to the country technical requirements, may cause serious physical hazards by 
electric shock and/or fire to the technician.

GENERAL RECOMMENDATIONS

Only trained personnel can perform diagnostic and maintenance procedures on 
refrigeration systems.

Installation and repair requires special training, technical information, special tools and 
special equipment.

Make sure in advance if the environment for maintenance is adequate and airy. 
Tools and process equipment should be available. The required Personal Protective 
Equipment (PPE) must be used by the technician.

Before starting maintenance or diagnostics, first make sure that the cooling system is 
disconnected from the mains.

After disconnecting the system from the mains, wait for the compressor to cool 
down. Only perform maintenance or diagnostic procedures with the cold compressor 
(25 ° C ± 5 ° C).

The compressors shall be powered only in electrical installations with a ground fault 
circuit interrupter (GFCI) circuit breakers or residual current device (RCD), according to 
the country technical requirement.

Correct grounding is required for the use of compressors.
