Detailed System Reference
Water and Temperature Controls
The CleanTech® 500EZ blending valve is calibrated at the factory at a pre-set temperature (usually
between 100° - 107° Fahrenheit). While the calibrated temperatures are usually accurate /-
1° F, temperature can be dependent upon the hot and cold-water inlet temperatures and pressures.
Hot water is not produced by the CleanTech® system. If facilities hot water is not 135°F or greater,
the CleanTech® system may not be able to achieve the recommended 105°F hand wash temperature.
In cold rooms where the hot water loses its heat through the hot water pipe and cold-water
temperature is extremely low, it may be necessary to have a booster heater located near the
CleanTech® system. CleanTech® systems are not compatible with instantaneous or tank-less water
heaters. For specific application assistance, contact Meritech at 1-800-932-7707.
Consult with local plumbing authorities for proper connections and installation requirements. The
customer installed hot and cold-water control shut-off valves should be located near the system.
These valves control the supply of water from the main water lines to the system. If you detect a
water leak, close both the hot and cold water shut-off valves and unplug the system.
To decrease water pressure, splash out, and flow; partially close the facility hot/cold water valves
equally to achieve the desired pressure/flow.
Cylinder Rotation
The wash cylinders are made of durable plastic and can be slowed at anytime by placing light
pressure on the cylinder walls. This feature has been designed to ensure safe operation at all times.
Do not worry if large pieces of debris fall into the cylinders. The bottom of the cylinders will act as a
trap. Simply reach in and remove the debris. Smaller pieces of debris will fall through the cylinder
and out through the system drain.
