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.
