Vortex AC Operating Manual
3.6 Special Operating Notes
During normal operation, when the High Pressure switch activates the
machine will restart automatically when the head pressure drops below
approximately 28.9 bar.
4.0 Maintenance
Your Vortex AC will provide many seasons of reliable service providing it is
properly maintained. The actual maintenance requirements are minimal but
important.
Keep the unit clean by wiping it down with a damp cloth to remove dirt, oils,
etc., prior to storage for the day. Standard household detergent or isopropyl
alcohol may be used if the unit is particularly dirty — in all cases, exercise care
to prevent liquids from entering the unit. Gasoline and other solvents are to be
avoided as they can damage the Vortex AC’s plastic enclosure and they are
hazardous.
Ensure that the Inlet and Discharge ports are protected in transit and storage
— keep the inner diameter and the outer threads clear and clean. For best
results, keep a FILTER permanently connected to the INLET port and
change it regularly.
When performance falls off it is likely that the compressor seals require
replacing. This is normal with use and may occur after a year or two, or more
often depending upon the conditions that are prevalent during the recovery
operations. Contact your Wholesaler for assistance in selecting the proper
maintenance kit.
