APPROVED ACCESSORY ITEMS

4.1 The EVO-OS Refrigerant Recovery Machine requires the proper accessory items to ensure
the best performance. The following items are specifically identified to ensure safety and
operational requirements are met. Check with your Wholesaler to ensure that the proper
selections have been made.
4.1.1 REFRIGERANT HOSES should be made with approved materials, should be as short as
possible to perform the required operations and should have shut-off devices within
300mm of the ends. Approved hoses are:
Refrigerant Hoses with UL Recognition and 20000 Kpa Burst Strength
4.1.2 RECOVERY CYLINDERS should be approved and have an appropriate pressure rating
for the refrigerant being recovered. Choose the size (normally 20 or 60 Kg) that is right
for the job, and be sure they have a cylinder full float switch. Approved cylinders are:
Refrigerant cylinders with Brad Harrison 3 pin connectors
4.1.3 FILTERS should be selected to protect the Inlet of the EVO-OS from particles of dust,
metal and other foreign materials that may be present in the refrigeration system. If
servicing a system with a burned out compressor, 2 or more FILTERS in series may be
necessary, and they should be discarded immediately after use. Approved filters are:
Filters UL recognized/CSA listed for Refrigeration Service
4.1.4 EXTENSION CORDS, when necessary, should be as short as possible and should
contain size 16 AWG (1.291 mm) or larger conductors. This is necessary to avoid
overheating during periods of high current draw and minimize the risk of fire. The
longer the extension cord required at the work site, the larger the conductor size should
be particularly for runs over 10m.

MAINTENANCE

5.1 Your EVO-OS will provide many seasons of reliable service if it is properly maintained.
The actual maintenance requirements are minimal but important.
5.2 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 EVO-OS's plastic
enclosure and they are hazardous.
5.3 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.
