Costguard CGS-20 Operating instructions

COSTGUARD CGS-20 FILTERS
APPLICATIONS AND FEATURES
These filters can be used for post mix, coffee, and ice applications. The economical Costguard
filters trap much of the dirt which contributes to scale buildup in ice
makers, and clogs the delicate orifices of other water-using equipment.** By selecting the
appropriate cartridge, your Costguard filter can reduce cysts, bad tastes and odors, and par-
ticulate for ingredient water.
• Taste and Odor Reduction • Fine Filtration (CGS-20/CG53 only)
• Sediment Reduction (CGS-20/CG53 only) • Cyst (CGS-20/CG53 only)
• Scale Reduction**
NOTE: The housing does not contain a filter cartridge. Choose the appropriate cartridge for
your needs and install in housing according to the cartridge replacement instructions before
proceeding with installation. See Cartridge Selection Guide.

INSTALLATION
The Costguard filter (part number EV9100-20) has 3/8" FPT con-
nections. Before starting installation, be sure to shut off both
power and water to the equipment being served by your
CostGuard system. For servicing purposes, a manual shut-off
valve should be installed in the water line.
IMPORTANT: Always use Teflon®tape at all thread connections.
1. Select a suitable location for mounting the prefilter and install
mounting screws 4-3/4" apart. The system should be close to
the machine served.
2. Separate the bowl and head assembly. Set the bowl and car-
tridge aside.
3. Check to be sure the o-ring on the bowl is sufficiently lubri-
cated. If additional lubrication is needed, use only a high qual-
ity grade of silicone grease.
4. Position the cartridge on the guide seat in the bottom of the
bowl. Then screw the bowl onto the head, by hand; do not use
a housing wrench!
5. Connect the water line to the inlet of the filter. (Use 3/8" mini-
mum piping on filter to assure adequate flow of water).
Connect outlet side to the next piece of equipment used.
6. Tu r n o n t h e w a t e r t o t h e f i l t e r a n d p r e s s t h e r e d b u t t o n o n t h e
head to open the pressure relief valve, purging air from the
system. When water begins coming through the pressure
relief valve, release the button. Inspect the filter
assembly for leaks. Your system is now in service. Always
keep a supply of replacements cartridges on hand.
NOTE: The drinking water cartridge may contain carbon fines
(very fine black powder). After installation, flush cartridge for 5
minutes to remove the fines before using the water.
CARTRIDGE CHANGE
Replace filter cartridges when they become excessively dirty,
when the pressure gauge after the filter indicates extremely low
pressure during water flow, or when changes in taste and odor
are detected.
1. Tu r n o f f i n l e t a n d o u t l e t w a t e r va l v e s a n d p r e s s t h e p r e s s u r e
relief valve.
2. Unscrew the bowl from the filter head, remove the used car-
tridge and empty the water from the bowl.
3. If the o-ring on the bowl feels dry, lubricate it with a high qual-
ity silicone grease.
4. Clean the bowl with a mild solution of unscented dishwashing
detergent. DO NOT use soap, strong or scented detergents,
chemical cleansers or abrasives.
5. Position the replacement cartridge on the guide seat in the
bottom of the bowl. Then firmly screw the bowl into the head
by hand. DO NOT USE A HOUSING WRENCH. Flush car-
tridge for 5 minutes to remove carbon fines before using the
water.
CAUTION: The o-ring provides a water tight seal. Make sure the
o-ring is properly seated and lubricated.
CARE AND CLEANING
For the protection of your filter, do not store open containers of
oils, alcohols, insecticides, polishes, cleaning fluids or other com-
mon household chemicals near your filter installation. To maintain
the clear, bright appearance of the filter bowl, clean only with mild
solution of unscented dishwashing detergent. Do not clean with
soap, strong or scented detergents, chemical cleansers or abra-
sives.
Check the system and installation for compliance with your state
and local laws and regulations. For cold water use only.
WARNING: Do not use with water that is microbiologically
unsafe or of unknown quality without adequate disinfection before
or after the system. Systems certified for cyst reduction may be
used on disinfected waters that may contain filterable cysts.

PERFORMANCE DATA
Important Notice: Read this Performance Data Sheet and compare the capabilities of this system with your actual water treatment
needs. It is recommended that, before installing a water treatment system, you have your water supply tested to determine your actual
water treatment needs.
This system has been tested according to NSF/ANSI 42 and 53 for the reduction of the substances listed below. The concentration of
the indicated substances in water entering the system was reduced to a concentration less than or equal to the permissible limit for water
leaving the system, as specified in NSF/ANSI 42/53.
Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts.
