Separator Tank Scavenge Screen/Orifice; Coolant Separator Element - Ingersoll-Rand XF250 Operator's Manual

COOLANT DRAIN
WARNING
Hot coolant can cause severe injury. Use care when near
this area.
After the unit is drained and a new coolant filter element
is installed, refill the system with fresh coolant. Bring the
receiver level of coolant up to the midpoint of the sight glass.
Replace the fill cap. Start the compressor and run it for a short
time. The correct coolant level is at the midpoint of the sight
glass with the unit running in the 'UNLOADED" mode.

SEPARATOR TANK SCAVENGE SCREEN/ORIFICE

TOOLS REQUIRED
• Open end wrench
• Pliers
PROCEDURE
The screen/orifice assemblies are similar in appearance to a
straight tubing connector and will be located between two
pieces of 1/4 inch O.D. scavenge line tubing.
The main body is made from 1/2 inch hexagon shaped steel
and the diameter of the orifice and a direction-offlow arrow is
stamped in flat areas of the hexagon.
A removable screen and orifice is located in the exit end of
the assembly (See Figure SEPARATOR TANK SCAVENGE
SCREEN/ORIFICE) and will require cleaning as outlined in the
Maintenance Schedule.
To remove the screen/orifice, disconnect the scavenge line
tubing from each end. Hold the center section firmly and use
a pair of pliers to gently grasp the exit end of the assembly
that seals against the scavenge line tubing.
Pull the end out of the center section while using care to
prevent damage to the screen or sealing surfaces.
Clean and inspect all parts prior to reinstallation.
When the assembly is installed, confirm the direction of
flow to be correct. Observe the small arrow stamped in the
center section and ensure the direction flow to be from the
separator tank to the airend.

SCHEDULED PREVENTATIVE MAINTENANCE
SEPARATOR TANK SCAVENGE SCREEN/ORIFICE

COOLANT SEPARATOR ELEMENT

To check condition of separator element, run compressor in
full load mode and at rated pressure and observe "Separator
Pressure Drop" on the CURRENT STATUS display screen. If the
display says "xxPSI", then no maintenance is required. If " ? "
is flashing on the screen and the display says "CHANGE SEPR
ELEMENT", then the separator element should be replaced.
Disconnect the scavenge tube at the airend.
Loosen the fitting that holds the scavenge tube into the tank
and withdraw the tube assembly.
Disconnect the piping from the tank cover. Tag the lines if
required.
Use a suitable wrench and remove the bolts that hold the
tank cover in position. Remove cover by lifting up and away.
Carefully lift the separator element up and out of the tank.
Discard the faulty element.
Clean the gasket surface on both the tank and its cover.
Exercise care to prevent pieces of the old gasket from falling
down into the tank.
Check the tank to be absolutely certain that no foreign
objects such as rags or tools have been allowed to fall into
the tank. Install replacement element down into the tank
after checking the new element gaskets for possible damage.
Center the element up within the tank.
Place the tank cover in its correct position and install
bolts. Tighten the bolts in a cross-pattern to prevent over-
tightening one side of the cover. An improperly tightened
cover will likely result in a leak.
