Congratulations on your purchase of the CUNO Foodservice ScaleGard
™
PLUS 2 water treatment system. The ScaleGard PLUS 2 systems utilize
some of the world’s most advanced scale and corrosion control tech-
nologies in a compact, highly efficient package.
The ScaleGard PLUS 2 system is designed for food service equipment
with low water draw such as steam kettles and tables, combis, electric
and gas steamers, misters or other applications, where water consump-
tion does not exceed 6 gph (22.7 lph) continuous. See estimated water
production chart below.
The ScaleGard PLUS 2 STM150 is recommended where a minimal
TDS level is required for proper equipment operation. The ScaleGard
PLUS 2 TSR150 is recommended for applications where zero hardness
is required such as proofing ovens, flash steamers, injection steamers
and misters.
Before beginning the installation, take a few minutes to familiarize your-
self with the system by reviewing the entire installation, operating and
maintenance manual. It is also important to review the criteria below
to make sure that the requirements have been or will be met when the
installation is complete. Be sure to confirm that the feedwater falls within
the limits shown below. If you’re not sure if this has been done, check
with your distributor before installing the system. This is important
because failures caused by water related problems are not covered
under the system warranty.
Installation must comply with state and local plumbing requirements.
