Pre-service Safety Check
It is strongly recommended that all service
techniciansreceivetrainingonthespecic
equipment,procedures,andhandlingofammable
refrigerants before conducting product service.
• Use a combustible gas leak detector
to perform a background check and
monitoring around the appliance.
To avoid a risk of injury, do NOT use leak
detectors with an arc or spark module to
check for leaks in and around appliances that
use A2L or A3 refrigerants. The leak detector
mustbecertiedforusewiththespecicrefrigerant
classbeingserviced.Ifammablerefrigerantis
detected, immediately ventilate the room, evacuate
the area, and notify the owner or customer. Recheck
with a combustible gas leak detector before
proceeding.
• Review the Safety Data Sheet (SDS) for the
refrigerant listed on the appliance’s ID Plate.
Because, some refrigerants and compressor
oils may cause frostbite and others may
cause chemical burns, use Personal Protective
Equipment (PPE) such as, protective gloves,
eyewear, etc.
• Ensure a dry-powder re extinguisher rated
forClassBresisaccessibleonsite.Technicians
shouldbetrainedintheuseofthesere
extinguishers.
• Utilize a tubing cutter, not a torch or
otherheatedsurfacetoolduetoammable
refrigerants.
• Conduct all servicing in a well-ventilated
area. Whenever possible, open a window, door
or other means to ventilate the area. Take extra
careiftherepairworkisdoneinaconned
space, including providing enhanced ventilation
topreventformationofammableatmospheres.
Before repair work is performed, take these
steps to ensure that no ignition sources are
present:
• Check the area for obvious sources of sparking or
openames.
• Ensuretheareaisfreeofopenameorburning
materials, including cigarettes, candles, or similar
materials.
• Do not operate appliances that utilize open
ames,igniters,orhavehotsurfaces(for
example: electric or gas ranges, electric or gas
dryers, toasters, and other small appliances)
while servicing the appliance.
• Inform the owner/consumer that no open ignition
sources should be present in or near the area,
including cigarette smoking materials.
• Check the area and the appliance for abnormal
signs of ignition or melting of components that
might have occurred prior to the service call.
If there are signs of these situations, stop and
contact the manufacturer before conducting
service.
• Maintain a safe zone around the appliance during
service work to prevent introduction of ignition
sources or entry by the customers.
• If the appliance is being moved to a service
center, take care to prevent damage to the
appliance, especially the refrigerant lines.
• Utilize vacuum pumps, recovery equipment, and
othertoolsthatareratedforandcertiedforuse
withA2LorA3ammablerefrigerants.Vacuum
pumpsmustbecertiedfortherefrigerantbeing
used. Service companies/technicians should
consider, where appropriate, the use of spark-
proof tools as an additional measure of safety.
Leak Detection and Coolant-line Repair
• Never use potential sources of ignition, open
ame,chargingwithammablerefrigerants,
or hot surface tools to detect the presence of
a leak. Use soap-bubble testing when charging
with oxygen-free dry nitrogen (OFN/OFDN), and
acertiedandcalibratedcombustiblegasleak
detector to test for leaks if the system is charged
with an A2L or A3 refrigerant.
• After repair, check for any vented refrigerants
with a combustible gas leak detector. If a leak is
detected or if the coolant lines must be repaired,
replaced,orlled,strictlyfollowallinstructions
provided by the manufacturer.

Back Bar Operation Installation Manual
Return to Table of Contents 10
• If the combustible gas leak detector signals a
release of vented refrigerant, the technician
should immediately ventilate the room, evacuate
the area, notify the homeowner or customer and
wait until the detection device reads a safe level
before conducting the following steps.
• Toreducetheriskofreorexplosion,neveruse
compressedairoroxygenforushing,pressure
testing, if a repair is made to the coolant lines.
• Purge refrigerant lines with oxygen-free
dry nitrogen (OFDN), both before and after
the repair. Technicians should be trained in
the use of OFDN purging.
• Direct purged gas discharged from the system
away from ignition sources or air intakes.
• Use the combustible gas leak detector to
determinetheenvironmenthasnoammable
refrigerant present.
• Donotuseexternalheatfromopenameor
heating tools with glowing elements to accelerate
the defrosting process. If necessary, a hand-
held steam cleaner can be used to defrost the
evaporator coils.
Recharging or Replacing Refrigerant
• Recharge the appliance with the exact
refrigerant specied by the manufacturer.
Any time the sealed refrigerant system
must be opened, including when the
compressor must be replaced, the original
exact refrigerant must be used. The
entire system (e.g. ttings, valves, dryers,
seals, tubes, etc.) was designed only
for the refrigerant listed on the original
compressor.
• DO NOT use heat sources to open the coolant
lines,especiallythosewithopenames.Use
mechanical means to cut, pierce or change
valves. If brazing of the lines is necessary, strictly
follow the instructions provided.
• Strictlyfollowspecicationsfortherechargingor
replacement of refrigerant.
Important Additional Safeguards
If an electrical fault exists that could compromise the
refrigerant,repairtheelectricalfaultrst.
Before performing service, discharge all capacitors in
the machine compartment and disconnect electricity
to the appliance, preferably at the circuit breaker.
No live electrical components or wiring should be
exposed during servicing of the refrigerant lines. If
electricity is necessary to conduct the service work
on systems other than the refrigeration system,
thoroughly test the refrigerant lines with the
combustible gas leak detector before electricity is
connected.
If the appliance has more than one refrigerant loop,
ensure all leaks are repaired and checked.
Do not expose refrigerant lines to materials that
might cause corrosion to the line or the seals such as
chlorine bleach or ammonia.
Repair or replace all electrical components with
theexactspeciedmodelandtyperequiredbythe
appliance manufacturer. Many electrical components
arespecicallyengineeredforuseinappliances
withammablerefrigerantsand must be replaced
accordingly.
Perform all service work in a manner to prevent
damage to electrical components and insulation.
In addition, return all wiring in such a way that the
operation of the appliance will not be damaged by
mechanical action.
Repair or replace all seals and sealing material to
ensure that the areas of the appliance are returned
to original condition.
When replacing refrigerant:
Ensure the refrigeration system is properly
grounded if the appliance is being operated during
charging.
Replace with the exact refrigerant and quantity
found on the nameplate/rating plate on the unit.
The refrigerant should be refrigerant-grade gas and
should not be contaminated with other gas materials.
Rechargewiththecorrectamountspeciedby
the manufacturer. Recharge accuracy is critical
forammablerefrigerants. Consult the service
instructions for the manufacturer and product in
question. Incorrect charge sizes could result in poor
performance.
