TEST OR INSPECTION
ICON 23, 25, 27, 26
Use care to prevent refrigerant from touching skin or eyes. Liquid refrigerant, when
exposed to air, quickly evaporates and will freeze skin or eye tissues. Serious
injury or blindness may result if you come in contact with liquid refrigerant.
Refrigerant R-134a air conditioning systems should not be pressure-tested or leak-
tested with compressed air. Combustible mixture of air and R-134a may form,
resulting in a fire or explosion, which could cause personal injury or death.
Wear protective goggles and non-leather gloves when servicing air conditioning or
injury could result.
Stop crew cab air conditioner (WP 0008). Connect service/recycling station (WP 0217).
Check if crew cab air conditioning system pressure is above 34 PSI (234 kPa) on
service/recycling station low-side pressure gauge (WP 0217).
If there is less than 34 PSI (234 kPa), perform leak test, repair leaks, and
service crew cab air conditioner (WP 0217).
