Inspect unit for shipping damage and report any damage to freight carrier.

INSTALLATION INSTRUCTIONS

A.   WALL MOUNT

   1.   Remove four 5/16” bolts from sides of cabinet near top and bottom of unit.
   2.   Use bolts removed in Step 1 to secure wall mount brackets to unit

as shown in  

FIG. 1

.

3.

Locate an installation site that will provide for the following:

A solid structure, capable of supporting the weight of the unit.

Three feet of unobstructed exhaust space from the outlet of the unit.

Easy access to service panels and unit inlet.

As near as possible to the source of oil mist unit to be captured.

FIG. 1

FIG. 2

4.

Mark location of mounting holes on the surface to which unit is to be mounted
(see 

Figure 2 

 for hole pattern).  Drill holes that are sized correctly for the

hole pattern in mounting hardware.

5.

Position the OM 500 wall mount bracket holes over the holes located on the
structure in Step 4.  Use 3/8” x 2” lag bolts or 3/8”  bolts and nuts to secure
the OM 500 to structure.

CAUTION: The size and weight of the OM 500 requires two persons or
mechanical means to lift and hold during mounting.

6.

Connect unit to oil mist source using a duct having the same diameter as
the inlet of the unit.  The duct may be flexible hose or formed sheet metal.
Maximum flow will be obtained with minimum bends in duct.  To contain oil
that will collect on the inside of the duct, the duct must be sealed.  Sloping

the duct toward the OM 500 will assist flow.  Use hose clamps or sheet
metal screws to attach duct to unit.

NOTE:

  Optional hose adapters are available for connection to 6” and 8”

diameter hose.  Use Part No. 34145-01 for 6” diameter hose, and Part No.
34145-02 for 8” diameter hose.  Attach adapter to plenum collar with sheet
metal screws and seal with RTV sealant.

B.
