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.
