INSTRUCTIONS FOR REPAIRING APPLIANCES
CONTAINING R290
GENERAL INSTRUCTIONS
Checks to the area
♦ Prior to beginning work on systems containing flammable refrigerants, safety checks
are necessary to ensure that the risk of ignition is minimised. For repair to the refrige-
rating system, the following precautions shall be complied with prior to conducting work
on the system.
Work procedure
♦ Work shall be undertaken under a controlled procedure so as to minimise the risk of a
flammable gas or vapour being present while the work is being performed.
General work area
♦ All maintenance staff and others working in the local area shall be instructed on the
nature of work being carried out. Work in confined spaces shall be avoided. The area
around the workspace shall be sectioned off. Ensure that the conditions within the area
have been made safe by control of flammable material.
Checking for presence of refrigerant
♦ The area shall be checked with an appropriate refrigerant detector prior to and during
work, to ensure the technician is aware of potentially flammable atmospheres. Ensure
that the leak tection equipment being used is suitable for use with flammable refrige-
rants, i.e. nonsparking, adequately sealed or intrinsically safe.
Presence of fire extinguisher
♦ If any hot work is to be conducted on the refrigeration equipment or any associated
parts, propriate fire extinguishing equipment shall be available to hand. Have a dry
powder or CO 2 fire extinguisher adjacent to the charging area.
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 flammable refrigerant shall use
any sources of ignition in such a manner that it may lead to the risk of fire or explosion.
All possible ignition sources, including igarette smoking, should be kept sufficiently
far away from the site of installation, repairing, removing and disposal, during which
flammable 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 flammable hazards or ignition risks. "No Smoking" signs shall be displayed.
(Original instructions)
Ventilated area
♦ Ensure that the area is in the open or that it is ade- quately 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 mainte- nance 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 out-
lets 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.
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.
REPAIRS TO SEALED COMPONENTS
♦ 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.
♦ 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
affected.
♦ This shall include damage to cables, excessive number of connections, terminals not
made to original specification, damage to seals, incorrect fitting 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 flam-
mable atmospheres. Replacement parts shall be in accordance with the manufacturer's
specifications.
♦ 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 COMPO- NENTS
♦ 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 flammable atmosphere. The test apparatus shall be
at the correct rating. Replace com- ponents only with parts specified by the manufactu-
rer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.
CABLING
♦ Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration,
sharp edges or any other adverse environmental effects. The check shall also take into
account the effects of aging or continual vibration from sources such as compressors
or fans.
DETECTION OF FLAMMABLE REFRIGE- RANTS
♦ Under no circumstances shall potential sources of ignition be used in the searching for
or detection of refrigerant leaks. A halide torch (or any other detector using a naked
flame) shall not be used.
