CAUTION
Most electronic components are suscepti-
ble to damage caused by electrical static
discharge (ESD). In certain cases, the hu-
man body can have enough static electric-
ity to cause resultant damage to the compo-
nents by touch. This is especially true of the
integrated circuits found in the Advance mi-
croprocessor.
CAUTION
Under no circumstances should a techni-
cian electrically probe the microprocessor
at any point, other than the connector termi-
nals where the harness attaches. Micropro-
cessor components operate at different
voltage levels and at extremely low current
levels. Improper use of voltmeters, jumper
wires, continuity testers, etc. could perma-
nently damage the microprocessor.
CAUTION
When setting the microprocessor time,
ensure that the clock you are using is accur-
ate. Also, some customers are located in
different time zones from the repair loca-
tion. If you know the owners desired loca-
tion time, enter that time. If you don't, enter
the current time at your location.
CAUTION
DO NOT leave the circuit energized for the
full 5 minutes if full amperage is shown, as
the intake air heater element life will be
greatly shortened.
CAUTION
Unit uses R404A and POE oil. The use of in-
ert gas brazing procedures is mandatory for
all Carrier Transicold refrigeration units;
otherwise compressor failure will occur.
For more information Refer to Technical
Procedure 98-50553-00 Inert Gas Brazing

Do not over torque display & keypad pan
head screws. Torque all screws to 60 inlbs
(6.8 Nm).
Running the engine for an extended period
of time with the manual plunger up can
cause a priming pump failure
Torque fuel level sensor mounting screws
to 15 to 18 inch/pounds. DO NOT over tight-
en, as little as 20 inch/pounds will damage
the sensor.
When changing oil filters, the new filters
should be primed (partially filled) with clean
oil if possible. If the filters are not primed,
the engine may operate for a period with no
oil supplied to the bearings.
NEVER POUR COLD WATER INTO A HOT
ENGINE, however hot water can always be
added to a cold engine.
Only a refrigerant cylinder that has previ-
ously been used with R404A should be con-
nected to this refrigeration unit.
Only a refrigerant cylinder containing
R404A should be connected to this refriger-
ation unit in order to pressurize the system.
However, dry nitrogen may be used to in-
crease pressure. Any other gas or vapor will
contaminate the system and require addi-
tional removal and evacuation.
Do not vapor charge R404A. Only liquid
charging through the liquid line service
valve is acceptable.
