• A service/shipping sleeve (54-00656-23) must be installed before removal of the generator from the
engine. The generator MUST be removed as an assembly, with the shim in place. DO NOT attempt to
separate the rotor or stator.
• Never disassemble the generator rotor from the stator due to the high force required to do so and the
high magnetic field that will result. The field present when the rotor is disassembled from the stator may
interfere with cardiac implants such as pacemakers and defibrillators.
• R-452A is an A1 non-flammable refrigerant blend. However certain of its constituents are considered A2L
mildly flammable. For this reason, it is imperative that the system of a Vector unit utilizing R-452A refrig-
erant be recovered to a sufficient vacuum to ensure all residual refrigerant is removed from the system.
Follow the R-452A refrigerant recovery procedure before performing any “hot work,” including but not lim-
ited to brazing or welding on a unit that has been charged with R-452A, to prevent flare up of residual
A2L refrigerant constituents. Refrigerant must be recovered until equipment gauge indicates 20 inHG (-
0.6bar) of vacuum.
• Service mode MUST be used whenever removing refrigerant charge, refrigerant leak checking or evacu-
ating.
• Before connecting a megohmmeter, place the main power switch in the OFF position. Disconnect the
high voltage source, lockout/tagout the receptacle and disconnect the negative battery connection. Iso-
late the microprocessor by disconnecting all connectors and wires going to it. Observe National Electric
Manufacturer’s Association (NEMA) rules and test equipment manufacturers instructions.
• Refer to Table 8–5 for Temperature Pressure Charts for R-452A refrigerant.
• Do not vapor charge R-452A. Only liquid charging is acceptable.
• The scroll compressor achieves low suction pressure very quickly. Do not use the compressor to evacu-
ate the system below 0 psig. Never operate the compressor with the suction or discharge service valves
closed (frontseated). Internal damage will result from operating the compressor in a deep vacuum.
• Under no circumstances should anyone attempt to repair the Logic or Display boards. Should a problem
develop with these components, contact your nearest Carrier Transicold dealer for replacement.
• Electronic modules MUST be handled with care to prevent accidental damage or degradation from elec-
trostatic discharge (ESD), contamination or abuse. Before touching a module, touch your body and/or
conductive tool being used to the frame to discharge ESD safely. All electronics should be handled care-
fully and only held by edges of any exposed board. Care should be taken when inserting/extracting con-
nectors and components to avoid exerting excessive stress on the board which could fracture small
components nearby, resulting in future failure of circuit.
