COLDRINK SERIES INSTALLATION AND OPERATION GUIDE
CARTRIDGE CHANGE DETERMINATION
Replace the prefilter cartridge whenever it becomes excessively dirty (observed visually or by flow restriction). Follow the
change instructions provided with the cartridge. Replace carbon filter cartridges when capacity is reached, or when flow
becomes inadequate, but at least annually. All carbon filter cartridges on multiple cartridge systems should be changed at
the same time. The system pressure gauge or accessory (sold separately) Everguard
TM
Low Pressure Alarm (LPA) provide
quick, simple means of determining when the filter cartridge(s) should be checked. Installed on the system outlet manifold,
the gauge or LPA can be used to monitor both dynamic (flowing) and static (line) pressure. The cartridge(s) should be changed
when the pressure gauge needle is in the red area while equipment is in operation, and yet the needle shows adequate line
pressure between cycles. Observe the needle during the next equipment on cycle. If the needle registers adequate pressure,
it can be assumed that the temporary low-pressure condition was caused by a brief power failure or other incoming pressure
disruption. If the low pressure condition is not due to an external condition, check/change the prefilter first. If the low pressure
condition is still not corrected, change the carbon filter cartridges.

FLUSHING
For maximum life, all carbon filter cartridges must be flushed for five (5) minutes at full flow before use.
ALL NEW CARTRIDGES MUST BE FLUSHED AFTER EACH CARTRIDGE CHANGE BEFORE BEING PUT INTO SERVICE!
If the cartridges are new, have been properly flushed and both needle and follower register inadequate pressure, or the LPA
is sounding, you may be experiencing inadequate water pressure or some restriction may exist in the inlet water line. In either
case, the incoming water pressure must be improved to receive optimum filter life.
COMPLETE CARTRIDGE CHANGE INSTRUCTIONS CAN BE FOUND ON THE FILTER CARTRIDGE LABEL.
Not for residential use. For food service applications only.
11. Open the flushing valve and flush the cartridge(s) by
running water through at full force for five (5) minutes.
This will set the filtering media and purge any air and
fines, insuring maximum filter life. See illustrations.
12. After flushing, close the flushing valve, turn on power
to equipment, and plug the LPA (if so equipped) into the
electrical outlet. The system is ready for operation.
Check for compliance with state and local laws and regula-
tions. 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.
For installations in Massachusetts, the Commonwealth of
Massachusetts Plumbing Code 248 CMR shall be adhered to.
Consult your licensed plumber for installation of the system.
This system and its installation must comply with state and
local regulations.
