2.3 Service Manual Safety Labels
PLEASE READ all instructions completely before
attempting to service the unit. Take particular
note of the DANGER, WARNING and CAUTION
information in this manual. The information
isimportantforthesafeandecientservice,
operation and care of the Perlick unit.
HAZARD!! Indicates hazardous situation that
will result in death or serious injury if not
avoided.
Indicates hazardous situation that may
result in death or serious injury if not
avoided.
Caution indicates hazardous situation that
could result in minor or moderate injury and
property damage.
Caution without symbol indicates unsafe practice
situation that could result in property damage only.
• Vacuum pumps must be explosion-safe. It must
be possible to lead the discharge air from the
vacuum pump into open air.
• Leak detection cannot take place with normal
halogen leak detectors, as they do not react on
hydrocarbons. A special detector reacting on
a hydrocarbon must be used instead. Another
possibility is to use a leak spray. Both solutions
only work properly if the vapor pressure in
the system is higher than 1 bar (atmospheric
pressure).
• If the pressure is lower than the normal
atmospheric pressure, it is necessary to raise
the pressure within the system to ambient
temperature.
Never use liquid to detect system leaks if
system is in a vacuum!
All self-contained models covered in this service
manual are manufactured using refrigerant
HC-600a (Isobutane).
2.2 Servicing with R-600a
R600a is a hydrocarbon. This refrigerant is
ammableandisonlyallowedforuseinappliances
whichfullltherequirementsofUL60335-2-24
(To cover potential risk originated from the use of
ammablerefrigerants).Consequently,R600ais
only allowed to be used in household appliances
whicharedesignedforthisrefrigerantandfulll
the above-mentioned standard.
• R600a is heavier than air. The concentration
willalwaysbehighestatoorlevel.
• The explosion limits are as follows:
Lower limit: 1.5% by vol. (38 g/m3)
Upper limit: 8.5% by vol. (203 g/m3)
Ignition temperature: 460°C
2.2.1 General
Do not use near open re. To carry out service
and repair on R600a systems the service personnel
must be properly trained to be able to handle a
ammablerefrigerant.Thisincludesknowledge
on tools, transportation of compressors and
refrigerant, and the relevant regulations and safety
precautions when carrying out service and repair.
2.2.2 Transportation of refrigerant and
replaced compressors
• The refrigerant must be stored and transported
in approved containers.
• Replaced compressors containing refrigerant
residues must be sealed before being
transported.
2.2.3 Tools
Ingeneral:Noopenrewhentroubleshootingand
repairing.
• The refrigeration circuit must be opened with a
tube cutter or a special tool.
