BEFORE USING THE AC880

Check for any shipping damage. Place a claim with carrier if damage is discovered. DO NOT USE A DAMAGED UNIT.

Complete and return the Warranty Card to activate technical support service and warranty coverage.

These general instructions describe normal operation and maintenance situations encountered with the AC880. Failure to read and comply with these instructions or any one of the limitations noted herein can result in serious injury and/or property damage.

A few minutes spent reading these instructions can make an operator aware of dangerous practices to avoid and precautions to take for his own safety and the safety of others. The instructions should not be interpreted to anticipate every possible contingency.

The AC880 should not be operated or serviced by any person who has not read all the contents of this manual.

It is the responsibility of the owner/user to operate the AC880 in accordance with all specifications and laws which apply.

A regular schedule of inspection of the AC880 should be established and records maintained with special attention given to Hoses, Compressor Oil Level, Vacuum Pump Oil Level, and Filters.

SAFETY PRECAUTIONS

Recover, Recycle, and Charge only the refrigerant for which the machine is configured.

Wear safety glasses and protective gloves. Refrigerant has a very low boiling point and can cause frostbite.

Follow the AC880 operating procedures sequentially to avoid prematurely disconnecting hoses or opening valves which may release refrigerant to the atmosphere.

Do not expose the AC880 to moisture or operate in wet areas.

Use the AC880 in locations with mechanical ventilation that provides at least four air changes per hour.

Hoses used with the AC880 must have shutoff devices within 12 inches (30 centimeters) of the connection point to the A/C System to minimize the introduction of Non-Condensable Gas (Air) into the AC880 and the release of refrigerant when being disconnected.

Disconnect power before performing any maintenance or service on the AC880. Connect the AC880 to a properly grounded receptacle. Do not overload the circuit.

Avoid using an extension cord with the AC880. If necessary use a good condition three wire, grounded, #14 AWG or larger extension cord of the shortest possible length.

Do not connect the AC880 to the liquid side of any A/C System with a capacity greater than 4 lbs (1.8 Kg). Refrigerant in A/C Systems having larger capacities must be recovered from the vapor side only.

Never connect the Red or Blue Hose on the rear of the AC880 to the Liquid Port of a Cylinder of Refrigerant to fill the Charge Cylinder. Doing so may cause the Compressor to fail and void the warranty.

Avoid breathing refrigerant or lubricant vapor or mist. Exposure may irritate eyes, nose and throat. If accidental system discharge occurs, ventilate work area before continuing.

Additional health and safety information may be obtained from refrigerant and lubricant manufacturers.

Special Considerations with R134a

R134a has been shown to be nonflammable at ambient temperature and atmospheric pressure. However, tests under controlled conditions have indicated that at pressures above atmospheric and with air concentrations greater than 60 percent by volume, R134a can form combustible mixtures.

While it is recognized that an ignition source is also required for combustion to occur, the presence of combustible mixtures is a potentially dangerous situation and should be avoided.

Under no circumstances should any equipment be pressure tested or leak tested with Air and R134a mixtures. Do not use compressed air (shop air) for leak detection in R134a systems.
