Safety instructions
degree of ventilation shall continue during the period that the work
is carried out. The ventilation should safely disperse any released
refrigerant and preferably expel it externally into the atmosphere.
8) Checks to the refrigeration equipment
Where electrical components are being changed, they shall be
fit for the purpose and to the correct specification. At all times
the manufacturer's maintenance and service guidelines shall
be followed. If in doubt consult the manufacturer's technical
department for assistance.
The following checks shall be applied to installations using
flammable refrigerants:
- The charge size is in accordance with the room size within which
the refrigerant containing parts are installed;
- The ventilation machinery and outlets are operating adequately
and are not obstructed;
- If an indirect refrigerating circuit is being used, the secondary
circuit shall be checked for the presence of refrigerant;
- Marking to the equipment continues to be visible and legible.
Markings and signs that are illegible shall be corrected;
- Refrigeration pipe or components are installed in a position
where they are unlikely to be exposed to any substance which
may corrode refrigerant containing components, unless the
components are constructed of materials which are inherently
resistant to being corroded or are suitably protected against being
so corroded.
