Important Safety Information
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
The following checks shall be applied to installations
using fl 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 become
illegible must 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 suitable
protected against being 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 no live electrical components and wiring
are exposed while charging, recovering or
purging the system.
• That there is continuity of earth bonding.
Repairs to sealed components
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. To ensure that by working on electrical
components the casing is not altered in such
a way that the level of protection is affected,
particular attention shall be paid to the
following:
• Damage to cables, excessive number of
connections, terminals not made to original
specifi cation, damage to seals, incorrect fi tting
of glands, etc.
• Ensure the 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
fl ammable atmospheres. Replacement parts
shall be in accordance with the manufacturer's
specifi cations.
Note: The use of silicon sealant may inhibit the
effectiveness of some types of leak detection
equipment. Intrinsically safe components do not
have to be isolated prior to working on them.
Repair to intrinsically safe components
Do not apply any permanent inductive or
capacitance loads to the circuit without ensuring
that this will not exceed the permissible voltage
and current permitted for the equipment in use.
Intrinsically safe components are the only types that
can be worked on while live in the presence of a
fl ammable atmosphere. The test apparatus shall
be at the correct rating. Replace components only
with parts specifi ed by the manufacturer. Other
parts may result in the ignition of refrigerant in the
atmosphere from a leak.
