CAUTION
!
If starting a unit for the first time after installation, or starting after adding/removing an optional
feature, or if Owner’s operating parameters have changed, the Configuration will need to be
reset.
CAUTION
!
Compressor failure will occur if inert gas brazing procedures are not used on units with R-134a
and POE oil. For more information see Technical Procedure 98-50553-00 - Inert Gas Brazing.
CAUTION
!
To prevent trapping liquid refrigerant in the manifold gauge set, be sure set is brought to suc-
tion pressure before disconnecting.
CAUTION
!
When working with refrigerant, use safety glasses and gloves to avoid burns. Hoses and cop-
per tubing can be hot when unit is running.
CAUTION
!
Do not damage or over tighten the enclosing tube assembly. Place all parts in the enclosing
tube in proper sequence in order to avoid premature coil burn-out.
CAUTION
!
Observe proper polarity when installing battery. Negative battery terminal must be grounded.
CAUTION
!
Under no circumstances should a technician electrically probe the processor at any point,
other than the connector terminals where the harness attaches. Microprocessor components
operate at different voltage levels and at extremely low current levels. Improper use of voltme-
ters, jumper wires, continuity testers, etc. could permanently damage the processor.
CAUTION
!
Most electronic components are susceptible to damage caused by electrical static discharge
(ESD). In certain cases, the human body can have enough static electricity to cause resultant
damage to the components by touch. This is especially true of the integrated circuits found on
the microprocessor. Use proper board handling techniques.
