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.
USING THE AC880 Note: The purpose of this discussion is to familiarize the user with the features and functions of the AC880 Refrigerant Handling Station. The procedures discussed in this manual assume that the AC880 has been set up in accordance with the figures which are referred to and that the AC880 has been connected to the proper power supply. This manual does not illustrate correct A/C service, but rather how to correctly use the AC880.

DRAIN RECOVERED OIL Oil is separated from the recovered refrigerant and MUST be removed following EACH Recover/Recycle procedure to determine the amount (if any) necessary to add into the A/C System as follows: Note: The AC880 must be connected to power source. Drain Recovered Oil may be done while the AC880 Vacuum Pump is ON. 1. Press and hold the Oil Drain Re-pressurization Switch (16) for 5 seconds and then release it. 2.

SCHEDULED MAINTENANCE DAILY... Check the oil level in the Vacuum Pump while the pump is running. The Vacuum Pump Oil Level Sight Glass is visible through a hole in the Lower Rear Panel of the AC880. The oil level should be at the “half-way” point of the glass. If oil is not visible call Technical Support at 800-468-2321 (Ext. 259). MONTHLY... Check the oil level in the Compressor while the motor is not running.

TROUBLESHOOTING FILL CYLINDER PROCEDURE 1) The cylinder of new refrigerant should be at ambient temperature or greater for best performance of the Fill Cylinder procedure. Make sure the cylinder was not recently moved from an air-conditioned storage room to a warm work area. Place the cylinder on a block of wood if necessary to elevate it from a cool concrete floor. Application of a heat belt to the cylinder will greatly enhance the speed.
