Kit number 205EAU4013 including the oil stop valve, check valve and flanges must be installed on all
remote elevated coolers per Figure 5-4, page 49, 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, and 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 49. 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 16.
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 54
.
Repeated addition of oil between oil changes may indicate
excessive oil carry-over and should be investigated.
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.
