Rinnai 7 Portable Room AC OIM
6) No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that
contains or has contained ammable refrigerant shall use any sources of ignition in such a manner that it may lead
to the risk of re or explosion. All possible ignition sources, including cigarette smoking, should be kept suciently
far away from the site of installation, repairing, removing and disposal, during which ammable refrigerant can
possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be
surveyed to make sure that there are no ammable hazards or ignition risks. No Smoking signs shall be displayed.
7) 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.
8) Checks to the refrigeration equipment
Where electrical components are being changed, they shall be t for the purpose and to the correct specication.
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
ammable 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.
9) Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and component inspection
procedures. If a fault exists that could compromise 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:
That capacitors are discharged: this shall be done in a safe manner to avoid 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.
7. Repairstosealedcomponents
1) During repairs to sealed components, all electrical supplies shall be disconnected from the equipment
being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an
electrical supply to equipment during servicing, then a permanently operating form of leak detection shall
be located at the most critical point to warn of a potentially hazardous situation.
2) Particular attention shall be paid to the following to ensure that by working on electrical components, the
casing is not altered in such a way that the level of protection is aected. This shall include damage to
cables, excessive number of connections, terminals not made to original specication, damage to seals,
incorrect tting of glands, etc. Ensure that apparatus is mounted securely. Ensure that seals or sealing
materials have not degraded such that they no longer serve the purpose of preventing the ingress of
ammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specications.
NOTE: The use of silicon sealant may inhibit the eectiveness of some types of leak detection equipment.
Intrinsically safe components do not have to be isolated prior to working on them.
