SAFETY INFORMATION
CAUTION
IMPORTANT NOTES
Read, understand, and follow all safety information contained in these instructions prior to
installation and use of the CUNO Foodservice STM150/TSR150 ScaleGard™ PLUS 2 Water
Treatment Systems. Retain these instructions for future reference.
Intended use:
The CUNO Foodservice STM150/TSR150 ScaleGard PLUS 2 water treatment systems are intended for use in
fi ltering and scale reductions for water used in coffee and espresso equipment, steam kettles and tables, combis,
electric and gas steamers, misters or other similar equipment, and have not been evaluated for other uses. The
system is typically installed near where treated water is desired, and must be installed as specifi ed in the instal-
lation instructions.
To reduce the risk associated with ingestion of contaminants due to use with water that is micro-
biologically unsafe or of unknown quality:
• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disin-
fection before or after the system.
To reduce the risk associated with hazardous voltage due to damage of the transformer/power supply:
• Do not use the ScaleGard system if the transformer/power supply is damaged — contact qualifi ed
service personnel for repair.
To reduce the risk associated with hazardous voltage due to an installer drilling through existing
electric wiring or water pipes in the area of installation:
• Do not install near electric wiring or piping which may be in path of a drilling tool when selecting the
position to mount the fi lter bracket.
To reduce the risk associated with back strain due to the heavy weight of the system:
• Follow safe lifting procedures.
EXPLANATION OF SIGNAL WORD CONSEQUENCES
CAUTION
WARNING
Indicates a potentially hazardous situation, which, if not avoided, could
result in death or serious injury and/or property damage.
Indicates a potentially hazardous situation, which, if not avoided, may
result in property damage.
WARNING
To reduce the risk associated with property damage due to water leakage:
• Read and follow Use Instructions before installation and use of this system.
• Install on cold water lines only.
• Installation must comply with existing state or local plumbing codes;
• Do not use a torch or other high temperature sources near fi lter system or cartridges;
• Protect from freezing. Drain fi lter when room temperature drops below 40°F (4.4°C);
• Do not install on systems where line pressures above 65 psi (448 kPa) may occur. Line water pres-
sure in excess of 65 psi will require installation of a pressure regulator prior to the unit;
• Shut off inlet water supply and depressurize system as shown in manual when changing cartridges or
servicing;
• The fi lter must be installed with the inlet and outlet ports as labeled. Make sure not to reverse connections;
• Do not install near water pipes which will be in path of a drilling tool when selecting the position to mount
the bracket;
• Mount the system in such a position as to prevent it from being struck by other items used in the area
of installation.
• Allow minimum of 3” (7.62 cm) clear space under [the assembly] to facilitate cartridge changes;
• All components should be accessible and have at least 6” (15 cm) of clearance on all sides of the
system to facilitate servicing.
