Safety Precautions 
Electrical Connection 
DISCONNECT the battery ground (-) on the vehicle battery. 
Engine Coolant 
All engines have a pressurized coolant system. Under 
normal operating conditions, the coolant in the engine and 
radiator is under high pressure and very hot. Do not remove 
the cap from a hot radiator. If the cap has to be removed, do 
so very slowly in order to release pressure without spray. 
Refrigerants 
The refrigerant contained in the refrigeration system of the 
units can cause frostbite, severe burns, or blindness when in 
direct contact with the skin or eyes. 
Personal Protective Equipment 
Always use personal protective equipment while doing 
anything on this refrigeration unit.
