Installation, Assembly, and Setup
Shimming, Grouting, and Caulking the
PCS Enclosure
To shim, grout, and caulk the PureWave SMS-250 PCS
enclosure, follow these procedures:
STEP 1.
After placing the PCS enclosure at the desired
location, check whether there are any gaps between
the enclosure and the concrete pad.
STEP 2.
If there are gaps, install shims until the enclosure is
level.
STEP 3.
Apply grout at the bottom of the enclosure as
necessary to prevent entry of insects or debris into
the enclosure. The grout should be recessed
sufficiently to permit injecting a bead of caulk
between the enclosure base and concrete pad.
STEP 4.
Apply a bead of caulk (S&C part number 6943- 010,
DAP Premium Polyurethane Waterproof Concrete
& Masonry Sealant 300 ml Gray) around the outer
edge of the bottom flange (where it meets the
concrete pad) to provide a seal around the base of
the PCS. The purpose of the caulk is to further
prevent ingress of insects and debris into the
enclosure.
Mounting
STEP 5.
Anchor the PCS enclosure to the concrete pad. Use
⅜
-inch (10-mm) diameter × 2-inch (51-mm) embed
Hilti Kwik Bolt TZ anchors for each bracket. The
anchor brackets should be located at each corner,
as shown in Figure 5. Tighten the bolts again three
to five days after the initial installation.
NOTICE
If seismic rating is required,
⅜
-inch diameter
× 2-inch embed Hilti Kwik Bolt TZ anchors
must be installed at each mounting bracket
location . Failure to do so can result in damage
to equipment .
STEP 6.
After pulling the cables, seal all conduit entrances
on the outside with room temperature vulcanization
silicone sealant and on the inside with duct seal
foam to prevent water from entering the PCS
enclosure.
