(l) Wrap teflon tape around threads of elbow (17) and insert into cylinder bleed valve (18). Tighten until
end faces the word "INLET' on body.
(2) Test reassembled moisture separator as follows:
(a) Install a suitable metal plug with sealing gasket in the safety outlet port of the shell (10).
Proof
pressure test the partially assembled moisture separator, in an environmental chamber using clean filtered air and
FSN 9150-753-4667 oil.
WARNING: EXERCISE EXTREME CARE WHEN WORKING WITH HIGH PRESSURE
AIR TO PREVENT INJURY TO PERSONNEL OR DAMAGE TO EQUIPMENT.
DO
NOT ATTEMPT TO TIGHTEN ANY FITTING OR PERFORM ANY WORK ON
EQUIPMENT WHEN THE SYSTEM IS UNDER. PRESSURE. DO NOT TAMPER WITH
ANY PRESSURE RELIEF VALVES.
(b) Connect a short length of tubing to drain port and connect a non-recoil fitting to the end of tubing.
Apply 4950 - 5000 psig air pressure to inlet port and 60 - 100 psi oil pressure to sensing port (elbow) for one minute,
utilizing test adapter. No leakage in excess of 3 cc per hour is permitted except at the dump port.
CAUTION: Hold unit in 30 degree vertical position with safety outlet up.
(c) Relieve inlet pressure and drain will discharge air when inlet pressure has decayed. Examine tested
unit; there shall be no indication of permanent deformation.
(d) Check moisture separator for leakage by applying 3000 psi pressure to the inlet port and 40 - 50 psig
oil pressure to the sensing port of cylinder. Air leakage shall not exceed 3 cc per minute at the dump port, 3 cc per hour
at other points. There shall be no oil leakage.
(e) Install mounting block (28) together with connector (25) and thermostat (22) onto body (34), if these
parts were not replaced. If, however, these parts were replaced, then prior to soldering wires slip protective tubing over
leads. Back pot
