CAUTION

IMPORTANT NOTES

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.

 • 

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.

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.
