Problem
Possible cause
Action
Remove the DRANE-KOOLER and
dislodge mineral accumulation.
Remove thermal sensor from
DRANE-KOOLER and gently remove
mineral accumulation with an abrasive
pad. Do not twist capillary tubing
during removal or cleaning.
Valve is not working properly.
Replace. Note: This valve is factory-
set and should not need adjustment.
The DRANE-KOOLER is designed to
handle hot water and hot condensate. If
a large amount of steam enters the
DRANE-KOOLER it is likely that
discharge water temperatures will be
greater than 140 °F (60 °C). Check
P-traps on humidifier or other
appliance to ensure that the P-traps
have the proper depth and are working
properly to prevent steam from
entering the DRANE-KOOLER.
If steam is entering the
DRANE-KOOLER, the introduction of
cold water through the valve will cause
the steam to collapse and make a
popping or crackling sound. Check
P-traps on humidifier or other
appliance to ensure that the P-traps
have the proper depth and are working
properly.
