Wall Mount Packages
NOTE: Refer to Fig. 3 and to the Wall Mounting Tem-
plate on page 21.
1. Ensure that the wall is strong enough to support
the weight of the pump and accessories, fluid,
hoses, and stress caused during pump operation.
2. Use the Wall Mounting Template on page 21 to set
the position of the wall bracket. The top edge of
the bracket should be 4 to 5 ft (1.2 to 1.5 m) above
the floor. Verify that the dimensions are exact and
the hole locations are level before drilling the
holes.
NOTE: It is easier to mount the wall bracket (31) if the
control bracket (4) and pump (1) are removed. Discon-
nect the air tube (12) from the elbow (11), then loosen
the two screws (3) and lift the control bracket (4) off
the screws. To remove the pump (1), remove the
screws (3) entirely.
3. Using the template, drill four 0.38 in. (9.6 mm)
diameter holes in the wall. Attach the bracket with
anchors and screws that are long enough to keep
the bracket from vibrating during operation. Check
that the bracket is level.
Suction Kit Accessories
Suction kits are available for the wall mount packages,
as an accessory. The kits must be ordered separately.
Refer to Table 2 for information.
