Cool ischarge hot water
The WATER-MIZER is a water saving and tempering
device that efficiently mixes cold water with steam conden-
sate discharged from sterilization equipment, such as a
steam sterilizer, to reduce the discharged water tempera-
ture 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, the WATER-MIZER is the solution!
Most steam sterilizers use continuous cold water to
temper the steam condensate, which is wasteful. The
WATER-MIZER monitors the drain temperature and
applies cold water only when needed!
Horizontal esign!
WATER-MIZER’s space-efficient horizontal orientation and
side drain outlet provide enough clearance to allow it to be
mounted directly underneath most steam sterilizers, saving
footprint space while allowing room for pitched drain pip-
ing.
How it works: Hot + col = tempere !
Steam condensate discharged from your sterilization
equipment enters the WATER-MIZER through piping
connected to the top threaded connection. A vacuum
breaker prevents backflow into potable water systems.
Cold water enters through the temperature-actuated
valve. The valve and the WATER-MIZER’s straight
forward design ensure efficient mixing of hot and cold
water. The valve’s sensor, located near the outlet,
ensures that water leaving the WATER-MIZER is
140°F (60°C) or less before entering the municipal
sewer system.
Tempered water at 140°F (60°C) or less exits through
the side outlet for safe discharge into a municipal
sewer system.
WATER-MIZER®features summary.
Reliable, non-electric valve
The temperature-actuated valve is time-tested to be
reliable. And because it is non-electric, no wiring is
required!
Built in thermometer
The WATER-MIZER has a built in thermometer for
easy calibration and continuous monitoring of
effluent temperature
Multiple mounting options
The WATER-MIZER can be mounted by attaching
the integral mounting plate directly to the frame of
the sterilization equipment or by attaching the
mounting plate to an adjustable floor stand. (See
Page 8 to order the Adjustable Floor Stand, RPI
Part #RP 470). These multiple mounting options
provide capability for the WATER-MIZER to be
properly supported and not secured entirely by pip-
ing.

Turn off steam supply to sterilizer and wait until jack-
et and chamber pressure is 0 psi.
Note that there are three connections to be made to
the WATER-MIZER:
• Cold water inlet
• ot water inlet
• Tempered water outlet to drain
Position the WATER-MIZER to allow the most direct
path of piping to minimize fittings.
Mount the WATER-MIZER by attaching the mounting
plate to the adjustable floor stand (see page 8 to
order the Adjustable Floor Stand, RPI Part
#RP 470), or by attaching the WATER-MIZER
directly to the frame of the sterilization equipment.
See page 4 for mounting options.
DO NOT SUPPORT WATER-MIZER ENTIRELY BY
PIPING. MOUNT WATER-MIZER FIRMLY BEFORE
PIPING.
Position unions on all connections as close to the
WATER-MIZER as possible to make cleaning and
maintenance easier. (For Maintenance Instructions,
see page 6.)
Cold water supply connection instructions:
• Cold water supply connection on valve is 3/8" FPT.
• Disconnect jacket and chamber trap cooling valves
on sterilizer and plug all openings.
• Verify that the supply water pressure to the valve
will be at least 25 psi (172 kPa) and not more than
80 psi (552 kPa).
• Pipe a 3/8" line directly to the WATER-MIZER from
the main water supply line.
• Install a cold water supply union as close to the
WATER-MIZER as possible.
• Install a cold water shut-off valve before the union
in the cold water supply line.
Installation checklist.
Installation
ot water inlet connection instructions:
• ot water inlet connection is 1" FPT.
• Using Teflon®tape or pipe sealant, install
brass tee and vacuum breaker assembly pro-
vided, to the sterilizer drain inlet on the
WATER-MIZER.
• Locate a union as close to the WATER-
MIZER as possible
• Connect all sterilizer drain lines to 1" pipe
and run pipe as directly as possible to the
WATER-MIZER. If the piping to the sterilizer
drain inlet has a horizontal run, maintain a
pitch to the WATER-MIZER of at least 1/8"/ft
(1%).
STERILIZER DRAIN LINES MAY BE OT!
USE CAUTION. MAKE SURE STEAM SUP-
PLY IS S UT OFF.
Tempered water outlet connection instructions:
• Tempered water outlet connection is 2" MPT.
• Install a union as close to the WATER-MIZER
as possible.
• Run a 2" pipe as directly as possible from the
WATER-MIZER 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.
Fill the WATER-MIZER tank with cold water
before initial use. If the WATER-MIZER is run
empty, excessive noise may occur.
Turn on sterilizer and using the built-in
thermometer, monitor drain water temperature.
Adjust valve on case as indicated to maintain
drain temperature below 140°F (60°C).

Step-by-step installation instructions

Two mounting options
There are two different mounting options available to
ensure that the WATER-MIZER will be properly sup-
ported and not secured entirely by piping.
Mounting option 1: Sterilizer Frame Mount
Several options exist for mounting WATER-MIZER
to a sterilizer’s frame, making it the most widely used
mounting technique. Mounting the WATER-MIZER
to the frame may require that holes be drilled in the
frame. Secure WATER-MIZER to the frame of the
sterilizer by attaching the integral mounting plate
to the frame.
Note: Sterilizer frame mount not illustrated due to
differences in framework on differing sterilizers.
Mounting option 2: Floor mount (shown
below).
Note: Adjustable floor stand (RPI Part #RP 470) can
be ordered separately (see page 8).

WATER-MIZER®operation.
Operation
Steam condensate discharged from your
sterilization equipment enters the WATER-
MIZER through piping connected to the top
threaded connection. The vacuum breaker
prevents backflow into potable water systems.
Cold water enters through the temperature
actuated valve. The valve and the WATER-
MIZER’s straight forward design ensure
efficient mixing of hot and cold water. The
valve’s sensor, located inside the chamber
near the outlet, ensures that water leaving the
WATER-MIZER is less than 140°F (60°C)
before entering the municipal sewer system.
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.

Step-by-step maintenance instructions
Shut off steam supply to sterilizer.
Caution: hot pipes.
Shut off cold water supply.
Make sure jacket pressure is 0 psi.
Disconnect service unions at:
• Cold water inlet
• ot water inlet
• Tempered water outlet
Remove the WATER-MIZER 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 WATER-
MIZER to dislodge mineral deposits. Dump
mineral deposits and rinse.
WATER-MIZER®maintenance.
Maintenance
Maintenance:
Maintenance instructions 6
Annual preventive maintenance on your WATER-MIZER
is recommended.
If severe mineral accumulation has occurred,
remove the split nut holding the sensor in place
and remove the thermal sensor from the WATER-
MIZER chamber. Gently clean the sensor with an
abrasive pad. Do not twist the capillary tube
uring removal or cleaning. Remove the built-in
thermometer from the WATER-MIZER. Using an
abrasive pad clean any accumulated mineral.
Fill the WATER-MIZER with cold water. Reconnect
service unions, and open cold water supply valve
and steam supply valve to the sterilizer to resume
operation. Do not run the WATER-MIZER ry –
excessive noise may occur.
The temperature of the effluent should be checked
as part of the current planned maintenance proce-
dures for the sterilizer which it is attached to. The
internal thermometer should be checked against a
calibrated external thermometer (or temperature
probe) annually.
