The shipped loose kit includes the oil stop valve, check valve and flanges and must be installed on all
remote elevated coolers per Figure 5-4, page 41, and the following instructions:
1.
Mount the check valve (90J113) as shown.
2.
Mount the drain valves in the lowest section of the pipe on each side of the cooler connections.
3.
Mount the oil stop valve (90AR243) in the line after the thermal mixing valve as shown.
Modifications to the control lines will be made at the factory per 263EAU810 schematic. Air to the oil stop
valve must come from the upper fitting in the separator housing, then pass through the 3-way pneumatic
valve. Control air to the valve must be from the line between the tee and the orifice in the blowdown
muffler line per Figure 5-4, page 41. When the machine blows down, it will activate the pneumatic valve
and it will shut off the air and vent the line between the pneumatic control valve and the oil stop valve to
atmosphere. This will shut the oil stop valve and prevent excessive oil from running into the reservoir.
Failure to install these parts or installations with pipe lengths and/or vertical runs outside the
recommended limits could result in high oil carryover and cause the machine to shutdown on
high discharge temperature.
COLD AMBIENT OPERATION
- See “Installation for Cold Weather Operation,” page 12.
ADDITION OF OIL BETWEEN CHANGES
must be made when the oil level is in the red range on the
gauge as read while the unit is on. To add oil, follow these steps:
1.
Be sure the unit is completely off and that no air pressure is in the oil reservoir.
2.
Disconnect, tag and lockout the power supply to the starter.
3.
Wipe away all dirt around the oil filler plug.
4.
Remove the oil filler plug and add oil as required to return the oil level to the center of the green
range on the gauge.
5.
Install the oil filler plug, restore power, run and check for leaks.
DO NOT OVERFILL. The quantity required to raise the oil level from the red range center of the green
range is shown in Figure 5-6, page 46
.
Repeated addition of oil between oil changes may indicate
excessive oil carry-over and should be investigated.
DANGER
Air/oil under pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, lockout and tagout
power supply to the starter before removing valves, caps, plugs, fittings, bolts
and filters.
