•
Check the differential pressure on the pre-filter, which should not exceed
10 PSID. Values greater than this indicate that the filter cartridge must be
changed.
•
Check the differential pressure on the after-filter, which should not exceed
10 PSID. Values greater than this indicate that the filter cartridge must be
changed.
•
Check the backpressure at the silencer placed behind the exhaust valve
combination; it should not exceed 5 PSIG. Use the gauge of the vessel
that is to be regenerated.
•
Drain inlet and exhaust valve chambers using valves provided below the
valve (refer to photo attached).
•
Drain pilot air filter housing of condensate (refer to photo attached).
