safety and warranty
• The appliance is to be installed in accordance with the Safety Standard for Refrigeration Systems, ANS\/
ASHRAE 15.
• 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.
•
Before carrying out Decommissioning procedure, it is essential that the technician is completely familiar
with the equipment and all its detail. It is recommended good practice that all refrigerants are recovered
safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is
required prior to re-use of recovered refrigerant. It is essential that electrical power is available before the
task is commenced.
• When removing refrigerant from a system, either for servicing or decommissioning, it is recommended
good practice that all refrigerants are removed safely.
• The recovery equipment shall be in good working order with a set of instructions concerning the equipment
that is at hand and shall be suitable for the recovery of all appropriate refrigerants including, when
applicable, FLAMMABLE REFRIGERANTS.
•
The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and
the relevant waste transfer note arranged. Do not mix refrigerants in recovery units and especially not in
cylinders.
•
The maximum loading of each type of shelf is 8kg.
• 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.
• If any hot work is to be conducted on the refrigerating equipment or any associated parts, appropriate fire
extinguishing equipment shall be available on hand. A dry chemical or CO2 fire extinguisher should be
adjacent to the charging area.
• No person carrying out work in relation to a REFRIGERATING SYSTEM which involves exposing any pipe
work 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 cigarette smoking, should be kept sufficiently far away from the site
of installation, repairing, removing and disposal, during which refrigerant can possibly be released to the
surrounding space. Prior to work taking place, the area around the equipment shall be surveyed to make
sure that there are no flammable hazards or ignition risks.“No Smoking” signs shall be displayed.
• 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 toxic or flammable atmospheres.
Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e.,
no spark, adequately sealed, or intrinsically safe.
• 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.
• 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.
• Detection of flammable refrigerants: 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.
