4.8 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.
Inspect tank scavenge screen and orifice. Clean if
necessary following instructions in Section 4.7.
Install scavenge tube down into the tank until the tube
just touches the separator element and then raise it 1/8
inch (3.2 mm). Tighten fittings.
Install the regulation lines in their original position.
Start unit, check for leaks, place in service.
