Water Conditioning
Untreated water contains scale producing minerals which
can precipitate onto the surfaces in the steam genera-
tor. Due to the temperatures in the steam generator, the
minerals can bake onto the surfaces and components.
This can result in early component failure and reduced
product life. Water level probes become coated with
scale. Scale may bridge across the probe insulator from
the metal extension which senses the water level in the
steam generator shell. Once this scale becomes wet, the
water level control is unable to maintain the proper water
level in the steam generator.
STRAINERS and FILTERS will NOT treat equipment
for scale reduction. This equipment is furnished with an
CUNO
®
Commercial Series water filtration system. An ini
-
tial flushing procedure for the filter system must be per
-
formed before using this equipment.
FILTER SYSTEM INSTALLATION SET-UP
1. Remove sanitary cap from cartridge. Install cartridge
with a quarter turn to the right until cartridge comes to
a complete stop. (A “click” is heard). See “Figure 3”.
2. It is recommended that cartridges be replaced
regularly, at no more than six-month inter-
vals, to be assured of optimum performance.
See “Figure 4”.
To replace cartridge:
a. Shut off inlet water.
b. Open a downstream valve to relieve pressure.
c. Unscrew the cartridge in the direction shown in
the illustration and discard.
d. Lubricate o-ring of new cartridge with water. DO
NOT use petroleum jelly.
e. Install by turning new cartridge toward the right
until it comes to a complete stop. DO NOT over
tighten. (Never use tools to tighten a cartridge).
f. Turn on inlet valve, bleed air through a down-
stream valve until water appears clear, and check
for leaks. System is now ready for use.
