Figure 5-4 – CHANGING OIL COALESCING ELEMENT
Oil Coalescing Element Service –
Use the following procedures to replace or inspect the element:
1.
Be sure the unit is completely off and that oil sump is depressurized.
2.
Disconnect, lockout and tagout power supply to the compressor package.
3.
Remove cap screws and body of MPV/sump cover (1).
4.
Lift the air/oil coalescing element from sump.
5.
Inspect and/or replace the element if necessary - shine a light inside the element to reveal areas of heavy
dirt, varnish deposits or breaks (ruptures) in its media. Also inspect (sealing) o-ring in element for damage.
Before installing new or old element, apply (heavy) grease to sealing o-ring – to avoid damage during
installation.
6.
Inspect oil scavenge orifice (3) and strainer (4) for fouling. Replace if necessary.
7.
Wipe the MPV/sump cover seal o-ring (5) clean and inspect for damage. Replace if necessary.
8.
Lower element into sump and press element down into holder. Do not use excessive force as element
damage may occur.
9.
Carefully place MPV/sump cover and o-ring seal on sump flange. Check that centering pin (on MPV/sump
cover) has engaged element cavity and that MPV/sump cover lays flat against sump flange. Install and
tighten cap screws.
10. After compressor is started and pressurized, inspect MPV/sump cover joint for leaks. Reset oil coalescing
element service interval in AirSmart controller.
