SEPARATOR ELEMENT REPLACEMENT
Refer to Figure 5-6. 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 twelve (12) 5/8 x 2.25 in cap-
screws and lock washers 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 gaskets.
7. Make sure grounding staples are attached to
separator gasket.
8. Replace the receiver tank cover. Install the
twelve (12) 5/8 x 2.25 in capscrews and lock
washers in finger-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 adjacent to each other. Torque
capscrews to 112 to 127 ft.lbs (151 to 172
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.
NOTE
RELIEVE PRESSURE PRIOR TO
WORKING ON.
