WATER SUPPLY
The water meter requires separate hot and cold supply lines. A manual shutoff valve (not supplied) should
be installed on each supply line at the water meter to accommodate servicing and shutdown.
•
HOT WATER INLET TEMPERATURE: 140°F (60°C) recommended.
•
HOT AND COLD WATER FLOWING PRESSURE: 30 psi (207 kPa) minimum.
•
WATER HARDNESS: 4 to 6 grains per gallon (0.7 to 1.0 grains per liter) is recommended.
DRAIN CONNECTIONS (FIG. 3)
The water meter should be located near a sink for the bypass line to drain into while test fl owing or when
water is adjusting to a set temperature.
For water meters equipped with a water chiller and with a water reservoir, a bypass return line should be
connected back to the water chiller reservoir.
NOTE: The hot and cold water supply lines can vary in location.
