EPARATOR LEMENT EPLACEMENT
Refer to Figure 6-5. When fluid carry-over is evident
after the fluid return-line strainer and orifice, as well
as the blowdown valve diaphragm, have been
inspected and found to be in satisfactory condition, or
if the separator restriction gauge reads in excess of
10 psig (0.7 bar), separator element replacement is
necessary. Follow the procedure explained below:
1. Remove all piping connected to the receiver
tank cover to allow removal (return line, ser-
vice line, etc.).
2. Remove the fluid return line from the fitting in
the cover.
3. Remove the cover capscrews and lockwash-
ers and lift the cover from the receiver tank
with the minimum pressure/check valve in
place.
4. Remove the separator element.
5. Scrape the old gasket material from the
cover and the flange on the receiver tank. Be
sure to keep all scrapings from falling inside
the tank.
6. Install the separator element.
7. Make sure grounding staples are attached to
separator gasket. DO NOT REMOVE STA-
PLES.
8. Replace the receiver tank cover. Install the
eight (8) capscrews and lockwashers in fin-
ger-tight, then gradually tighten in a criss-
cross pattern in 4 to 5 steps. Always tighten
the capscrews alternately at opposite sides
of the cover. Never tighten capscrews adja-
cent to each other. Torque capscrews to 206
ft.lbs (280 N·m).
9. Reconnect all piping. The fluid return line
should extend to the bottom of the separator
element or no more than 1/16 in (1.6 mm) up
from the bottom. This will assure the proper
fluid return flow.
10. Clean the fluid return line strainer and clear
the orifice prior to restarting the compressor.

6.10 PRESSURE RELIEF VALVE

An inoperable relief valve may not open properly to
protect the compressor from overpressure. A relief
valve unable to close can lead to a large loss of fluid.
The function of the pressure relief valve should be
checked on a weekly basis.

6.11 HOSE MAINTENANCE

Inspect and replace inlet, lubrication and control line
hoses every 600 hours or six months. Replace if any
damage or is present.
