DRANE-KOOLER features summary.
Cool discharged hot water
DRANE-KOOLER is a water tempering device that
mixes cold water with hot water discharged from
various types of equipment, such as a humidifier, to
reduce the discharged water temperature before it
enters a municipal sewer system.
There are two reasons to use a water tempering
device. First, most municipalities prohibit draining
water hotter than 140 °F (60 °C) into their sewer
systems. And second, PVC drain pipes are susceptible
to damage from water that is too hot. When faced
with either of these situations, DRANE-KOOLER is
the solution!
New horizontal design!
A new space-efficient horizontal orientation and side
drain outlet provide enough clearance to allow the
DRANE-KOOLER to be mounted directly
underneath DRI-STEEM humidifiers, saving
footprint space while allowing room for pitched drain
piping.
Reliable, non-electric valve
The temperature-actuated valve is time-tested to be
reliable and maintenance-free. And because it is nonelectric, no wiring is required!
Multiple mounting options
The DRANE-KOOLER can be mounted by attaching
the integral mounting plate to a wall, by attaching the
mounting plate to an adjustable floor stand, or by
using an assembly for suspension mounting. These
multiple mounting options provide capability for the
DRANE-KOOLER to be properly supported and not
secured entirely by piping.
How it works: Hot + cold = tempered!
1. Hot water discharged from a humidifier or other
appliance enters the DRANE-KOOLER through
piping connected to the top threaded connection.
A 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 140 °F (60 °C)* or less
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.

Installation
Installation checklist.
Step-by-step installation instructions
q Verify that maximum flow of hot water into the
DRANE-KOOLER does not exceed 6 U.S.
gallons per minute (gpm) (22.7 L/m).
q Note that there are three connections to be made
to the DRANE-KOOLER:
Cold water supply
Hot water inlet (from a humidifier or other
appliance)
Tempered water piping to drain
q Position the DRANE-KOOLER to allow the
most direct path of piping to minimize fittings
(see the piping diagrams on Pages 6-7).
q Position unions on all connections as close to the
DRANE-KOOLER as possible to make cleaning
and maintenance easier.
q Cold water supply connection instructions:
Cold water supply connection on valve is
3/8"(DN10) NPT.
Pipe a 3/8" (DN10) line directly to the
DRANE-KOOLER from the main water
supply line.
TO ENSURE ADEQUATE WATER
PRESSURE TO THE DRANE-KOOLER, DO
NOT CONNECT TO A SUPPLY WATER
LINE THAT IS DEDICATED TO OTHER
APPLIANCES.
q Hot water inlet connection instructions:
Hot water inlet connection is 1" (DN25) NPT.
Locate a union as close to the
DRANE-KOOLER as possible
Run 1" (DN25) pipe as directly as possible
from the hot water appliance (humidifier) to
the DRANE-KOOLER. If the piping to the hot
water inlet has a horizontal run, maintain a
pitch to the DRANE-KOOLER of at least
1/8"/ft (1%).
q Tempered water (to drain) connection
instructions:
Tempered water outlet connection is
2"(DN50) NPT.
Install a union as close to the
DRANE-KOOLER as possible.
Run a 2"(DN50) pipe as directly as possible
from the DRANE-KOOLER to the drain.
Maintain a pitch to drain of at least 1/8"/ft
(1%).
Make sure there is a 1" (25 mm) air gap
between the drain piping and the drain.
If installing the DRANE-KOOLER with a
humidifier, do not branch off the 1/4" (DN8)
cold water supply line to the humidifier.
Verify that the supply water pressure to the
valve is at least 25psi (172kPa) and not more
than 80psi (552kPa).
Install a cold water supply union as close to
the DRANE-KOOLER as possible.
Install a cold water shut-off valve before the
union in the cold water supply line.

Maintenance
DRANE-KOOLER maintenance.
Step-by-step maintenance instructions
q Shut off cold water supply.
q Disconnect service unions at:
Cold water supply inlet
Hot water inlet
Tempered water drain outlet
q Remove the DRANE-KOOLER from piping
and take to a service sink. Add water and,
with pipe caps or hands covering the hot water
inlet and tempered water outlet, shake the
DRANE-KOOLER to dislodge mineral deposits.
Dump mineral deposits and rinse.
q If severe mineral accumulation has occurred,
remove the thermal sensor from the
DRANE-KOOLER chamber and gently clean
the sensor with an abrasive pad. Do not twist the
capillary tube during removal or cleaning.
q Reconnect service unions and open cold water
supply valve to resume operation.

Valve is not working properly.
Replace. Note: This valve is factoryset 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.

Troubleshooting guide
Makes a loud popping
or crackling noise
Steam is 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.
