8. Close all the valves and disconnect all the external hoses. Connect the
hoses according to the recovery operation to do the gas refrigerant
recovery.
9. PURGE
When the reading on the electric scale shows that the refrigerant
in the tank reaches 80% capacity, please turn the power off and
close the valves on the tank.
12. Maintenance
Your ENVIRO will provide many seasons of reliable service if it is properly
maintained. The actual maintenance requirements are minimal but
important.
Keep the unit clean by wiping it down 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 ENVIRO's plastic enclosure, and
they are hazardous.
Clean inlet particle filter regularly. Discard internal filter screen if it is
heavily contaminated and replace with a new screen. Replace screen as
per sketch for efficiency.
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. Change
hoses periodically as they develop leaks and a build-up of contaminants
over time. Change hoses at least once per season.
When performance declines 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.
