HOW TO OPERATE
Once properly installed, to operate simply open the cold water supply line .
PRINCIPLE OF OPERATION
1 . Hot water discharged from a humidifier or other appliance enters the Drane-
kooler through piping connected to the top threaded connection . The vacuum
breaker prevents backflow into potable water systems .
2 . Cold water enters through the temperature-actuated valve . The valve and the
Drane-kooler’s straightforward design ensure efficient mixing of hot and cold
water . The valve’s sensor, located near the outlet, ensures that water leaving
the Drane-kooler is less than 140 °F (60 °C)* before entering the municipal
sewer system .
3 . Tempered water at 140 °F (60 °C)* or less exits through the side outlet for
safe discharge into a municipal sewer system or PVC pipe .
*Please see the capacities table on Page 4 .
