3. When necessary, it is possible to clean the primary filter (which has the screen across its face) in
either of these two ways:
5—8
· Blow 30 psi (2kg/cm 2 or bar) of air from the clean side.
— or —
· Soak and periodically agitate the filter in hot water containing a non-volatile cleaning
agent and then air dry the filter completely before installation.
4. If after cleaning or replacing the primary air filter the air pressure drop returns to normal, that is
an indication that the secondary filters are still clean. However, if the air pressure drop remains
high with the clean or replacement primary filter, it is time to replace the secondary filters.
CAUTION:
Do not operate the compressor for more than 2 minutes without the primary filter. Operation
without proper filtration may cause compressor damage or malfunction.
Bypass Valve Filter Element Replacement
On compressors so equipped, a filter is located in the pilot supply line to the bypass valve. It serves to
prevent water and/or other contaminants from entering the bypass valve’s control mechanism. Use a
Cooper Turbocompressor replacement filter only.
The replacement procedure is as follows:
1. Completely shut down the compressor and exhaust any pressure in the bypass valve air supply line
and filter.
2. Unscrew the canister that houses the filter from the base.
3. Remove the retaining nut that holds the filter element in place.
4. Inspect the canister o-ring seal; if damaged, replace it at this time.
5. Install the replacement filter element.
6. Replace the retaining nut (being careful not to over-tighten it) and then screw on the filter canister.
