The device must be returned in its original packaging and accompanied by the receipt, subject to proper handling.
Therefore, observe the operating instructions and safety instructions given above. In addition, we cannot
guarantee your device if you or a third party has made any modifications or repairs.
SERVICE OPERATIONS
This document describes the precautions for use by personnel responsible for service operations.
Any person required to work on a refrigerant circuit should hold a valid and up-to-date certificate from an assessment
authority accredited by the industry and recognising his competence to handle refrigerants safely, in accordance with the
assessment specification recognised in the industry sector concerned.
Service operations must only be carried out in accordance with the recommendations of the equipment manufacturer.
Maintenance and repair operations requiring the assistance of other qualified persons must be carried out under the
supervision of the person competent for the use of flammable refrigerants.
-
Checking the area :
Before starting work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of
ignition is reduced. For repairs to the refrigeration system, the following precautions must be observed before working on
the system.
-
Intervention procedure
Interventions must be undertaken as part of a controlled procedure in order to minimize the risk of flammable gas or
vapour during the work.
-
General work area
All maintenance personnel and other persons working in the local area must be informed of the nature of the work
performed. Any work in confined spaces must be avoided. The area surrounding the workspace must be divided into
sections. Ensure that conditions within the area have been made safe by controlling flammable materials.
Checking the presence of refrigerant
-
The area must be checked with an appropriate refrigerant detector before and during the work to ensure that the
technician is aware of the existence of potentially explosive atmospheres. Ensure that the leak detection equipment used
is suitable for use with flammable refrigerants, i. e. it does not produce sparks, is properly sealed and has intrinsic safety.
-
Presence of fire extinguishers
If work causing heat is to be carried out on refrigeration equipment or its associated parts, appropriate fire protection
equipment must be available within easy reach. A dry powder or CO2 extinguisher must be located near the loading area.
-
Absence of ignition sources
No person performing work related to a refrigeration system involving the exposure of pipes that contain or have
contained flammable refrigerants shall use ignition sources in a manner that may lead to a risk of fire or explosion. All
possible sources of ignition, including a person smoking a cigarette, should be located far enough from the installation,
repair, removal and disposal site during the period when the flammable refrigerant can flow into the surrounding space.
