Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before breaking
into the system or conducting any hot work. A 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.
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 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 that are
inherently resistant to being corroded or are suitably protected against being so
corroded.
Checks to electrical devices
Repair and maintenance of electrical components shall include initial safety checks and
component inspection procedures. If a fault exists that could compromise the safety,
then no electrical supply shall be connected to the circuit until it is satisfactorily dealt
with. If the fault cannot be corrected immediately but it is necessary to continue
operation, an adequate temporary solution shall be used. This shall be reported to the
owner of the equipment so all parties are advised.
Initial safety checks shall include:
those capacitors are discharged: this shall be done in a safe manner to avoid the
possibility of sparking;
that there no live electrical components and wiring are exposed while charging,
recovering or purging the system;
that there is continuity of earth bonding.
WARNING! Install the unit in rooms that exceed 10 m².
WARNING! Do not install the unit in a place where inflammable gas may leak.
