ABOUTTHISVALVE
The thermostatic mixing valve cartridge does not
contain an integral volume control/shut-off valve.
Youmust install a separate volume control/shut-off
valve (K-403) downstream of any valve outlet that
doesnothaveanintegralshut-offvalve.TheK-400
thermostatic mixing valve requires separate
volume control/shut-off valves downstream of
each mixing valve outlet. Refer to Fig. #3.
The K-401 thermostatic mixing valve contains a
single volume control/shut-off valve for controlling
the water flow through the shower outlet. When
plumbingtothevalve’sbath outlet, you must install
a separate volume control shut-off valve (K-403)
downstream from the bath outlet. Refer to Fig. #3.
K-400 and K-401 thermostaticmixing valvesdo
not have an integral aspirator. For installations
that use a bath diverter spout, you must install a
twin ell (K-9663) with integral aspirator between
the valve and the bath spout. If these thermostatic
mixing valves are installed without an aspirator
water will flow from the shower and bath spout at
the same time. Refer to Fig. #3.
Determine the correct drain size and capacity for
your installation. If two thermostatic mixing valves
are used together, water flow volumes of 24 gpm
(1.51 lps) or more are possible, depending upon
the water supply pressure.
Determine the correct water heater size and
capacity for your installation. A typical shower
installation uses an approximate mix of 75% hot
water and 25% cold. A custom shower application
using three 2-1/2 gpm (.16 lps) showerheads can
useabout45gal.(170.3l)ofhotwaterin8minutes.
Choose a water heater large enough for your
installation.
NOTES
Shut off the main water supply.
Observe all local plumbing codes.
Inspect the waste and supply piping for damage.
Replace as necessary.
The valve is calibratedto 104F(40C) at the first
stop position, and the maximum temperature limit
stop is positioned so the outlet water temperature
does not exceed 120F (49C).
Factory calibrated inlet conditions are:
Hot and cold water pressure = 43-1/2 psi (3.05
kg/cm)
Hotwatersupplytemperature=149F(65C)
Coldwatersupplytemperature=59F(15C)
If inlet conditions differ from those used during
factory calibration, it may be necessary to
re-calibrate the valve after installation. The
installer must check the mixed flow
temperature after installation, and adjust the
valve as needed according to the instructions.
ThisvalvecomplieswithASMEA112.181M,ASSE
1016, and CSA B125. The valve is listed with
ASSE, CSA, and IAPMO/UPC.

3. INSTALLATION
CONSTRUCT FRAMING AND INSTALL
ROUGH PLUMBING
Determine the desired location for the valve according to
the rough-in information on Page 3, and construct
suitable stud and support framing.
Use 3/4” nominal copper tubing and fittings throughout
this installation. Smaller diameter piping upstream or
downstream of the valve will reduce the performance of
the valve.
INSTALL VALVE
Flush the hot and cold water supply lines to remove any
debris.
CAUTION: Risk of product damage. This valve
contains plastic and rubber components. Do not
apply excessive heat to the valve body when you
make solder connections. Do not apply flux or acids
directly to the valve, as damage to the seals and
plastic components may result. Do not apply
petroleum-basedlubricantstothevalvecomponents,
as damage may result.
Use thread sealant, and connect the 3/4” hot and cold
water supply lines to the valve inlet ports. Install water
hammer arrestors in the supply lines. The inlet ports
are marked “HOT” and “COLD”, and must be connected
to the correct water supply lines to ensure proper valve
function. Make sure the integral volume control/shut-off
valve on the K-401 is on top.
Connect the water outlet lines to the valve ports. Use a
3/4” plug for any unused outlet port.

ADJUSTTEMPERATURE SETTINGS
This valve has been calibrated at the factory to provide
104F (40C) water at the mixing valve’s first stop
position. The maximum temperature limit stop has been
adjusted so the maximum water temperature will not
exceed 120F (49C).
NOTE: The listed water temperature settings are based
upon the following factory conditions:
Hot and cold water pressure = 43.5 psi (3.05
kg/cm)
Hot water temperature = 149F (65C)
Cold water temperature = 59F (15C)
If the actual water supply conditions differ significantly
from those listed, you may need to re-calibrate the valve.

NOTE: Do not turn the thermostatic mixing valve stem at
this time. Turning the mixing valve stem will change the
factory calibration setting.
Turn the water on for several minutes, then position a
thermometer in the water stream. If the existing water
supply conditions match the factory conditions, the water
temperature should be close to 104F (40C). If the
water temperature is not close to 104F (40C), remove
and discard the plaster guard if it is still attached.
Slowly rotate the thermostatic mixing valve stem until the

limit stop off the valve cartridge with a thin blade, and
re-install it so the white mark faces upward as required.
The limit stop must be correctly positioned to ensure trim
fit.
Do not turn the thermostatic mixing valve stem after you
adjust the temperature setting until you have installed the
mixing handle trim.
