2 SAFETY WARNINGS
■ it’s extremely important to follow the instructions in this manual. Do NOT attach any hoses or
accessories until prompted by the unit. Improper setup and failure of the unit will result.
■ always wear protection and protective clothing when working with refrigerants. Refrigerant can cause
injury. Read and follow all warnings in the operator’s manual and this service manual before service the unit.
■Disconnect hoses and tubes with extreme caution as they may contain liquid refrigerant under pressure.
■Always disconnect the unit from the power source before making any repairs or replacements to the
components. Risk of electrical shock! Avoid the use of extension cords because the extension cords may
overheat. However, if you must be NO.14AWG minimum and should not exceed more than 25 feet in length.
■Always depressurize the machine before servicing or replacing any components.
■Pressurized tanks contain liquid refrigerant. Overfilling of the tank may cause violent explosion and
possible injury or death. Do NOT recover refrigerants into a non-refillable storage container. Federal
regulations require refrigerants to be transported only in containers meeting DOT spec.4BW or DOT
spec.4BA.Or the relative EU refillable tank standards.
■Be sure that the refrigerant level in the tank does not exceed 80% of the tank volume. Failure to monitor
the level could result in excessive hydrostatic pressure, causing physical injury or death.
■If scale assembly and circuit are not calibrated, scale can overfill the tank, causing possible explosion
and/or vehicle overcharge.
■Use only ZELL Designated Replacement Components when servicing your equipment. Refer to the
operator’s manual or this service manual for correct replacement part number(s).
■When replacing component, make certain the new parts are connected exactly as your instruction sheet
directs you to do. If an instruction sheet was not included, connect the replacement part just like the original.
Mark or label wire and plumbing disconnections so replacing the new parts will confirm the previous
configuration.
■Use this unit only with R-134a OR R-12 refrigerant. The user must dedicate the unit to only one type of
refrigerant. Do NOT attempt to adapt the unit for another refrigerant. Do NOT mix refrigerant types through a
system or in the same container, mixing of refrigerants will cause sever damage to the unit and the vehicle air
conditioning system.
■Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may cause personal injury,
especially to the eyes, nose, throat and lungs. Use the unit in locations with mechanical ventilation that
provides at least four air change occurs, ventilate work area before resuming service.
■Keep hands away from moving parts. Such as a running fan.
■Do NOT use compressed air to pressure test or leak test the unit or vehicle A/C system. Some mixtures
of air and refrigerant have been shown to be combustible at elevated pressures. These mixtures are potentially
dangerous and may result in fire or explosion causing injury or property damage.
■Never use the parts, components and assembly as a un-designed purpose from the station.
This may cause extremely dangerous.
