Safety Considerations
Prior to installation this manual must be read carefully and all
instruction understood. Personal injury or product 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 your 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ƒ‡”
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

4. Standard bolted lid models should never exceed 150 psi;
V-Band clamp models should never exceed 125 psi.
5. •–ƒŽŽ„ƒ Ǧƪ‘™’”‡˜‡–‹‘†‡˜‹ ‡•ȋ‘” Š‡ ˜ƒŽ˜‡•Ȍ
both upstream and downstream of the strainer to
’”‡˜‡–„ƒ ƪ‘™‘”˜ƒ ——‡ơ‡ –•™Š‹ Š ƒ ƒ—•‡
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.

We recommend following the guidelines below when
installing your strainer:
1. Š‡•–”ƒ‹‡”•Š‘—Ž†„‡’Žƒ ‡†‘ƒƤ”ǡ•—’’‘”–‹‰
surface. Failure to do so can cause stress on the weld
joints. It is recommended a concrete pad 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
ˆƒ•–‡‡†ǤŠ‡ƒ””‘™• Ž‡ƒ”Ž›†‡’‹ –ƪ‘™†‹”‡ –‹‘
(see Figure 15).
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 pressure

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

safety and an adequate seal.

Žƒ’‡†‹†‘†‡Ž•ǣ CS strainer models 3CS and 4CS have
“over-center latch clamp” lid designs. The over-center clamp
does not require adjustment when installing or removing
the lid. The lock washer is set at the factory for proper clamp
‘’”‡••‹‘ƒ†‘”ƒŽŽ›”‡“—‹”‡•‘Ƥ‡Ž†ƒ†Œ—•–‡–Ǥ
Minor tightening may be necessary over time.
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 2 for proper lid bolt size and torque rating for each
strainer. (Exercise care when tightening the lid bolts so as not
to damage the strainer lid or housing).
–‹•‹’‘”–ƒ––‘ˆ‘ŽŽ‘™–Š‡–‘”“—‡•’‡ ‹Ƥ ƒ–‹‘•ƒ•‘˜‡”Ǧ
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 16 on page 40). The strainer

sequence (this is especially evident on the larger strainers such
as the DS-8 and larger). A second torque sequence should be
adequate to seat the lid securely to the body.
