7.0 MAINTENANCE
7.1 Your recovery machine will provide many seasons of reliable service if it is properly maintained.
The actual maintenance requirements are minimal but important.
7.2 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 plastic enclosure and are hazardous.
7.3 Clean inlet particle lter regularly. Discard internal lter screen if it is heavily contaminated and
replace with a new screen. Replace screen as per sketch for eciency.
7.4 Ensure that the Inlet and Discharge ports are protected and kept clean by replacing the plastic
caps after every use. For best results, keep a FILTER permanently connected to the INLET port and
change it regularly.
7.5 Change HOSES periodically as they develop leaks and a build-up of contaminants over time.
Change hoses at least once per season.
7.6 When storing the recovery machine for the season, or for long periods of time, PURGE the unit
with an inert gas such as nitrogen.
7.7 When performance falls o 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.
