Anchor Clamp Installation
Installation of anchor clamps is recommended in
high wind and seismically active areas. A Pentair
Anchor Clamp Kit (P/N 178840) is not included with
this filter, but can be purchased separately.
Anchor clamps hold the FullFloXF
®
4000-Series D.E.
Filter to the equipment pad in order to withstand
high winds caused during extreme weather, such as
hurricanes.
To install the anchor clamps:
1. Ensure the filter is in its permanent location on the
equipment pad.
2. Place the clamps into the base of the filter in the
four (4) anchor slots shown in
Figure 3
.
Note
:
Bolts and bolt anchors are not included with
the filter. The installer must provide 1/4” x 1-3/8”
stainless steel anchor bolts and the appropriate
size concrete anchor to mount the clamp to the
equipment pad. Be sure to follow local codes.
3. Fit the hook of each clamp into the anchor slots on
the base panel of the filter. See
Figure 3
.
4. Mark the position of the hole in each clamp on the
equipment pad.
5. Use a masonry drill bit and drill a hole in the
concrete with a diameter as determined by the
concrete anchor, at each of the marks on the
equipment pad. The hole should be approximately
1.5 inches deep. See
Figure 4
.
6. Insert a bolt anchor into each of the holes. Ensure
the anchors are set completely into the holes.
7. Position the anchor clamps so that the holes in
the clamps are over the bolt anchors.
Ensure the clamp hooks are over the lip of the
filter base.
8. Insert an anchor bolt through each clamp into the
bolt anchor and tighten to secure the clamp and
filter to the equipment pad.
