INLINE FILTER MAINTENANCE
It is recommended that the inline filter elements be
changed at a minimum of every 75 lbs of processed
refrigerant.
1. Pressure gauges must read zero or less. If not,
perform a recycle procedure.
2. Remove the red and blue service hoses from the
connection ports on the rear of the RHS980.
3. Use a deep 5/8 inch socket on the hose
connection fitting along with a 5/8 inch backing
wrench to remove the filter element housing (as
shown to right).
4. Remove the filter element and replace with a new
one. Note direction of filter during
reinstallation.
5. Carefully observe the amount of debris on the old
filter element. An excessive amount indicates the
need to change the filter more frequently. Filter
element replacement kits are available through
your local distributor.
6. Attach the red and blue service hoses - red on the
right and blue on the left. The connection ports
have red and blue markings.
7. During the next A/C service, use a leak detector to
ensure the inline filters and hoses are not leaking.
