Safety Considerations
Prior to installation, this manual must be read carefully
ƒ†ƒŽŽ‹•–”— –‹‘—†‡”•–‘‘†Ǥ‡”•‘ƒŽ‹Œ—”›‘”’”‘†— –
damage can occur if the following safety precautions are
overlooked or ignored. We strongly recommend that you
follow these safety precautions and avoid the potential
hazards listed below when operating and maintaining
the strainer:
1.
After unpacking your strainer, carefully inspect your
strainer housing, lid assembly and screen for damaged
or missing parts. Contact ClimaCool’s customer service
department for any replacement parts.
2.
Š‡•–”ƒ‹‡”•Š‘—Ž†‘–„‡‘†‹Ƥ‡†‘”—•‡†‹ƒ
manner not consistent with the manufacture’s
recommendations. If there are any questions regarding
its application or installations, contact ClimaCool’s
customer service department.
3.
Absolutely under no conditions should the strainer lid
or pressure gauges be removed while the strainer
is pressurized.
4.
Standard bolted lid models should never exceed 150 psi;
V-Band clamp models should never exceed 125 psi.
5.

both upstream and downstream of the strainer to

damage to the strainer housing or screen.
6.
Install properly sized pressure relief valves both
upstream and downstream of the strainer. This will
help prevent damage to the strainer and screen in the
‡˜‡––Šƒ–™ƒ–‡”ƪ‘™‹••–‘’’‡†ƒ„”—’–Ž›ǡ‘”‹ˆ™ƒ–‡”
hammering occurs. The pressure relief valves should
be set to relieve pressure at 1.2 times the strainer’s
maximum operating pressure (not to exceed the
maximum rated pressure). Consult your local dealer or
pressure relief valve manufacturer to obtain properly
sized valves for your application.
Note: Minimum 60 mesh screen is required. At no time
should the internal pressure exceed the maximum rated
pressure of the strainer.
Strainer Installation Recommendations
Follow the recommended guidelines below for strainer
installation:

be poured under the base of the strainer. The weight
of the CS strainer should not be supported by the main
water lines connecting it.
2.
The inlet and outlet connections should be securely

3.
The back-mount pressure gauges should be installed
in the gauge ports located on the front of the strainer
body. These gauges will allow you to monitor the

an indication when the strainer element is clogged and
requires cleaning.
4.
The CS strainer lid must be securely fastened according

Clamped Lid Models: CS strainer models 3CS and 4CS have
“over-center latch clamp” lid designs. The over-center

The lids are installed as follows:
1.
Place the clamp around the strainer lid.
2.
Latch the T-bolt with the receiver and push the latch
handle towards the strainer body until the safety
catch engages.
Bolted Lid Models: CS strainer models 6CS, 8CS and 10CS
have “bolted” lid designs. Grade 5 zinc-plated bolts, nuts
and washers are used to attach the lids to these strainers.
See Table 8 for proper lid bolt size and torque rating for each
strainer (page 48). (Exercise care when tightening the lid
bolts so as not to damage the strainer lid or housing).
–‹•‹’‘”–ƒ––‘ˆ‘ŽŽ‘™–Š‡–‘”“—‡•’‡ ‹Ƥ ƒ–‹‘•ƒ•
over-tightening may result in premature failure of the bolts.
It is equally important to follow a star wheel torque pattern
when tightening the lid bolts (see Figure 30). The strainer lid

seat the lid securely to the body.
