Do not use a nitrogen cylinder without
a pressure regulator. Cylinder pressure
is approximately 159.9 bar (2350 psig).
Do not use oxygen in or near a refrigerant
system as an explosion may occur. (See
Figure 8-19)
High voltage (dielectric) testing must not
be performed on the machine without first
observing NEMA rules. The insulation of
this generator winding may be safely
checked by using a megohm meter. A high
reading indicates good insulation.
Generators of this type should not be
"flashed". Operation with external voltage
source or momentary shorting of leads will
damage the generator and may cause inju-
ry.
Under no circumstances should anyone at-
tempt to repair the Logic or Display
Boards. Should a problem develop with
these components, contact your near-
est Carrier Transicold dealer for replace-
ment.
Service Mode MUST be used whenever re-
moving refrigerant charge, refrigerant leak
checking or evacuating.
The display and MessageCenter may be-
have differently during the software load-
ing process, depending on the version of
software currently in the controller. DO
NOT INTERRUPT THE SOFTWARE IN-
STALLATION PROCESS ONCE IT HAS
STARTED.
Unit uses R-404A OR R-452A and POE oil.
The use of inert gas brazing procedures is
mandatory for all Carrier Transicold refrig-
eration units; otherwise compressor failure
will occur. For more information Refer to
Technical Procedure 98-60068-00 Inert Gas
Brazing
When changing oil filter, the new filter
should be primed (partially filled)
with clean oil if possible. If the filter is
not primed, the engine may operate for
a period with no oil supplied to the bear-
ings.
Use only monopropylene glycol anti-freeze
as glycol by itself will damage the cooling
system. Always add pre-mixed 50/50 anti-
freeze and water to radiator/engine. Never
exceed more than a 60% concentration of
anti-freeze. Use a low silicate anti-freeze.
The mica shim must be used during disas-
sembly of the generator from the engine.
Never attempt to remove the rotor from the
stator. Leave the shim in place until the
generator is re-installed on the engine.
NEVER POUR COLD WATER INTO A HOT
ENGINE, however hot water can always be
added to a cold engine.
Only a refrigerant drum containing R-404A
or R-452A should be connected to this re-
frigeration unit in order to pressurize the
system. However, dry nitrogen may be
used to increase pressure. Any other gas
or vapor will contaminate the system and
require additional purging and evacuation.
