8.3 Routine Maintenance
A. Isolate Unit
1. Disconnect Power to the Unit
2. Close isolation valves (customer mounted ) and allow pressure to vent off the system.
B. Change Filters
1. Unscrew the housing from the filter head and drain off any oil in the housing into a suitable
container. Stuff clean rag into filter bowl to keep unit clean while changing the elements.
2. Unscrew the locking nut on the bottom of the element and discard the element. Replace the
element with a new one of the appropriate grade and replace the locking nut. Do not over
tighten..
3. Auto drain – Each filter is fitted with an internal automatic float drain to carry away
condensate (water & oil). There should only be a small amount of liquid in the housing. As
the level of the oil increases, the float rises and discharges liquid from the housing. If a large
amount of oil is found, remove the auto drain, clean or replace.
4. Replace Filter housing. After replacing the element, remove the rag and screw the housing
back on to the filter head. Do not over tighten. Housing is sealed with an o-ring, so gently
hand tighten.
5. Repeat this process for all three (3) filters.
C.
Change Carbon -
Once per year or every 4000 hours, replace the carbon in the carbon vessel. The
vessel will need to be removed from the machine to re-fill with carbon.
1. Disconnect the union fittings at the top and bottom of the housing.
2. Remove the bolts in the mounting brackets (floor and side brace) that hold the vessel in place
and remove the vessel from the unit.
3. Unscrew one of the screens from either end (3/4” nipple) to allow access to the carbon. Take
precautions to not damage the threads. Drain the carbon into a container and replace with
fresh BM-000427 carbon.
4. Replace screen.
5. Re-mount the vessel, connect the piping and secure.
