Flow Rates
SPECIFICATIONS
• Minimum Flow Rate: 3 L/Min at mid-blend with
equal dynamic supply pressures.
• Maximum Flow Rate: 215 models: 40 L/Min
For applications which may be outside the
operating parameters which follow, refer to Kohler
Mira Ltd, or Local Agent.
For Type 3 installations, the supply conditions
specified in the ‘TMV3 Requirements Manual’
take precedence over the operating parameters
which follow.
•
•
Pressures
• Max Static Pressure: 10 Bar.
• Max Maintained Pressure: 5 Bar.
• Min Maintained Pressure (Gravity System):
•
* Pressure Loss Ratio (PLR) is the ratio between
the hot and cold supply pressures after the
back pressure from outlet pipes, flow controls
and fittings have been deducted from each inlet
supply pressure.
For example, if the back pressure (measured
immediately at the outlet of the mixing valve,
and before any flow controls or fittings) is 1 bar,
the cold water pressure is 3 bar and the hot
water pressure is 2 bar then the pressure loss
ratio will be:
0.15 Bar (0.15 bar = 1.5 Metre head from cold
tank base to outlet).
For optimum performance supplies should be
nominally equal.
Temperatures
• Factory Pre-set (Blend): 215 models: 41°C,
222 models: 44°C (bath fill applications).
• Blend Temperature Range: full cold to

at mid-blend (which equates to maximum
pressure loss of 3.5 bar), 222 models: 60 L/
Min at mid-blend (which equates to maximum
pressure loss of 3.0 bar).
Maximum Recommended Flow Velocity in
pipelines: 2 metres/second.
Maximum Pressure Loss Ratio* should not
exceed 10:1, in favour of either supply, during
flow.
(3-1):(2-1) = 2:1 in favour of the cold supply.
The pressure loss ratio for Rada 215 and 222
thermostatic mixing valves should ideally be 1:1
(i.e. nominally equal inlet pressures). To achieve
this a suitable pressure regulating device should
be fitted to either inlet as necessary.
approximately 60°C, depending on hot water
supply temperature.
Optimum Thermostatic Control Range: 35°C
to 50°C (achieved with supplies of 15°C cold,
65°C hot and nominally equal pressures).
Recommended Hot Supply: 60°C to 65°C
Note! The mixing valve can operate at
higher temperatures for short periods without
damage, however this could detrimentally
affect thermostatic performance. For safety
and performance reasons it is recommended
that the maximum hot water temperature is
limited to 65°C.
Cold Water: up to 25°C.
Minimum Recommended Differential between
Hot Supply and Outlet Temperature: 12°C.
Pressure loss ratio should not be confused
with pressure ratio, which is the ratio of the
inlet pressures only and takes no account of the
back pressure.
Note! High back pressures make it more difficult
for a valve to control correctly.
Flow Rate vs Pressure Loss Graph
(Mixing Valve only, equal dynamic supply pressures
and mid-blend temperature setting). There will be
additional pressure losses through the outlet fittings.
Thermostatic Shut-down

• For safety and comfort the thermostat will
shut off the mixing valve within 2 Seconds if
either supply fails (achieved only if the blend
temperature has a minimum differential of
12°C from either supply temperature).

Flow Control
Note! Should the supplies be reversed then
the mixing valve will not be able to control
temperature. This can be corrected by rotating
the thermostatic cartridge within the valve body,
refer to section: ‘Installation, Outlet Position/
Reversed Inlet Supplies’.
All models can operate in any plane, and may
be inverted if necessary for pipework layout
convenience, provided hot and cold pipework
is connected to the appropriate inlets (hot - red,
cold - blue).
Rada 215 and 222 mixing valves do not have
integral flow control; appropriate provision must
be made for this in the outlet pipework.
This can be in the form of basin/bath tap,
stopcock, mechanical timed-flow controller or
solenoid.
The device chosen must be non-concussive in
operation.

INSTALLATION
General
Rada 215-t3 oem, 215 dk, 215-t3 dk, 222 dk and
222-t3 dk models only:
These models are readily adaptable for rising or
falling pipework; flat-faced union connectors (not
supplied on all models) allow the valve body to
accept a variety of pipework configurations, and
to be reversed or inverted as appropriate.
Installation must be carried out in accordance
with these instructions, and must be conducted by
designated, qualified and competent personnel.
1. Before commencing, make sure that the
installation conditions comply with the
information given in section: 'Specifications'.
For Type 3 valves. See also installation
conditions in the 'TMV3 Requirements
Manual'.
2. The mixing valve should be positioned for
easy access during use and maintenance.
All routine maintenance procedures can
be conducted with the mixing valve body
in place (except for strainer and non return
valve access on dk and oem models). For all
models, allow a minimum of 80 mm clearance
in front of the temperature control to enable
removal of the Thermostatic Cartridge during
maintenance.
3. Conveniently situated ‘full bore’ isolating
valves must be provided for maintenance
purposes.
4. The use of supply-line or zone strainers
will reduce the need to remove debris at
each mixing valve point. The recommended
maximum mesh aperture dimension for such
strainers is 0.3 mm.
5. I n l e t p r e s s u r e t a p p i n g s w h i c h a l l o w
measurement of the inlet pressures to the
mixing valve under operating conditions are
particularly recommended for healthcare
applications with Type 3 valves.
6. Pipework must be rigidly supported.
7. Certain types of system can result in the
thermostatic mixing valve having excessive
‘dead‑legs’ of pipework, or auxiliary cold
water supply added to the mixed water from
the thermostatic mixing valve. Such systems
can disguise the onset of thermostatic mixing
valve malfunction and should not be used.
8. Supply pipework layout should be arranged to
minimise the effect of other outlet usage upon
the pressures at the mixing valve inlets.
9. Inlet and outlet threaded joint connections
should be made with PTFE tape or liquid
sealant. Do not use oil-based, non-setting
jointing compounds.
10.To eliminate pipe debris it is essential that
supply pipes are thoroughly flushed through
before connection to the mixing valve.
1057616-W2-E
215-t3 c and 215-t3 zc models only:
These models are supplied with inlet connections
configured hot - left, cold ‑ right, and top outlet
as standard. It is essential that the inlet supplies
correspond with the markings on the thermostatic
cartridge. Should the existing hot and cold
pipework make this configuration inconvenient,
or a bottom outlet position be required, the valve
inlets or outlet can be reversed, as detailed
below. If both the outlet and inlet positions
require reversing, it is easier to simply rotate the
complete mixing valve 180°, and then reposition
the temperature knob or cap.
Outlet Reversal should be done prior to
installation of the mixing valve body. Rotate the
body 180° so that the outlet is in the opposite
direction, then follow the procedure for reversing
the cartridge .
Reversed connections can be altered before or
after mixing valve installation.
Reversing the Cartridge
1. If the mixing valve has already been installed,
isolate the supplies and open an outlet fitting
to release pressure and to assist the draining
of residual water.
2. Remove the temperature knob or locking cap,
using a 3 mm hexagonal key.
Note! Do not remove the temperature hub.
3. With the removal clip in place, unscrew the
head nut using a 35 mm wrench, this will begin
to draw the thermostatic cartridge out of the
body and release the indicator trim (adjustable
models).
8
7. Carefully align and then tighten the head nut,
do not over-tighten (max torque 2.5 N/m - 1.85
lbf ft).
8. Complete the installation, or, if the mixing
valve body has already been installed, restore
the hot and cold supplies and check for any
leaks.
9. If the temperature hub has been removed or
if the maximum temperature needs resetting,
check, and if necessary refer to section:
'Commissioning'.
10.Align and refit the indicator trim (adjustable
models) and refit and secure the temperature
knob or locking cap so that the markings will
be visible to the user.
Rada 215-t3 bc models only:
This model is supplied with inlet connections
configured hot - left, cold ‑ right, and top outlet
as standard. It is essential that the inlet supplies
correspond with the markings on the thermostatic
cartridge. Should the existing hot and cold
pipework make this configuration inconvenient,
or a bottom outlet position be required, the valve
inlets or outlet can be reversed, as detailed
below.
Outlet Reversal should be done prior to
installation of the mixing valve body.
Reversed connections can be altered before or
after mixing valve installation.
4. Remove the indicator trim (adjustable models)
and pull the thermostatic cartridge free of the
valve body.
5. Rotate the thermostatic cartridge 180°, which
reverses the position of the cartridge hot and
cold inlets.
6. Carefully push the thermostatic cartridge back
into the valve body, checking that the two
cartridge inlet port seals remain in place, and
locate the cartridge lugs into the body slots.
Important! Make sure that the markings on
the cartridge correspond with the hot and cold
inlet pipework.
Note! The red and blue markings on the
cartridge will now not correspond with the
body markings, so to avoid future confusion
remove the red and blue stickers from the
valve body.
Reversing the Outlet Position
1. Remove the outlet nipple using a 12 mm
hexagonal wrench.
2. Remove the outlet blanking plug using a 12
mm hexagonal wrench.
3. Screw the outlet nipple, complete with 'O' seal
into the bottom hole previously blanked and
tighten.
4. Screw the outlet blanking plug, complete with
'O' seal, into the top hole and tighten.
Reversing the Cartridge
If the mixing valve has not yet been installed
follow instructions 5 to 10, otherwise follow
instructions 1 to 15.
1. Unscrew the grubscrew using a 2.5 mm
hexagonal key and pull off the temperature
knob.
2. Carefully unclip the concealing plate from the
backplate.
Note! Use a screwdriver in the bottom cutout
to assist separation.

1057616-W2-E
3. Unscrew the two backplate screws and remove
the backplate from the mixer.
4. Using a 10 mm hexagonal key turn the integral
isolators 90° anti-clockwise to shut off the hot
and cold water supplies, and open an outlet
fitting to release pressure and to assist the
draining of residual water.
5. With the removal clip in place, unscrew the
head nut using a 35 mm wrench, this will begin
to draw the thermostatic cartridge out of the
body.
6. Pull the thermostatic cartridge free of the valve
body.
Caution! Some residual water may be
released.
7. Rotate the thermostatic cartridge 180°, which
reverses the position of the cartridge hot and
cold inlets.
8. Carefully push the thermostatic cartridge back
into the valve body, checking that the two
cartridge inlet port seals remain in place, and
locate the cartridge lugs into the body slots.
Important! Make sure that the red and blue
markings on the cartridge correspond with the
hot and cold inlet pipework.
Note! The red and blue markings on the
cartridge will now not correspond with the
body markings, so to avoid future confusion
remove the red and blue stickers from the
valve body.
9. Carefully align and then tighten the head nut,
do not over-tighten (max torque 2.5 N/m - 1.85

COMMISSIONING
Commissioning must be carried out in accordance
with these instructions, and must be conducted by
designated, qualified and competent personnel.
Exercising the Thermostat
Thermostatic mixing valves with wax thermostats
are inclined to lose their responsiveness if not
used. Valves which have been in storage, installed
but not commissioned, or simply not used for
some time should be exercised before setting the
maximum temperature or carrying out any tests.
A simple way to provide this exercise is:
(a) Make sure that the hot and cold water
are available at the valve inlets, and the
outlet is open.
(b) Move the temperature control rapidly from
cold to hot and back to cold several times,
pausing at each extreme.
7. Make sure that the hot and cold supplies have
been connected to the correct inlets, and that
all connections are watertight.
8. Refer to section: ‘Commissioning’.
OPERATION
Maximum Temperature
For adjustable temperature models adjustment of
the blend temperature from the preset maximum
to cold is achieved by clockwise rotation of the
temperature knob.
For locked temperature models no user adjustment
is intended.
Control of flow is via a separate outlet valve(s),
refer to section: ‘Specifications’.
Hot
Note! For Type 3 healthcare installations the
maximum blend temperature is determined by
the application, refer to the 'TMV3 Requirements
Manual'.
The maximum blend temperature obtainable by
the user should be limited, to prevent accidental
selection of a temperature that is too hot.
All Rada thermostatic mixing valves are fully
performance tested and the maximum temperature
is preset to approximately 41°C (222 models 44°C) under ideal installation conditions at the
factory.
Site conditions and personal preference may
dictate that the maximum temperature has to be
reset following installation.
This mixing valve is provided with two methods
of temperature setting, an adjustable temperature
control knob which allows the user to select the
blend temperature between ambient cold up
to a preset maximum, or if considered more
appropriate, a locked cap can be fitted, allowing
no user adjustment.
Cold
Adjustable Temperature Models Only

5. Check that blend temperature has not
altered.
6. For adjustable temperature refit the indicator
trim and temperature knob and secure with the
locking screw.
For locked temperature refit the locking cap,
engaging the cap guides into the body slots
and secure with the locking screw.
Check that an adequate supply of hot water is
available at the hot inlet of the mixing valve.
The minimum temperature of the hot water
must be at least 12°C above the desired blend,
however during resetting this should be close
to the typical storage maximum to offset the
possibility of any blend shift due to fluctuating
supply temperatures.
Check that both inlet isolating valves are fully open
and the inlet filters are clean.
Temperatures should always be recorded using
a thermometer with proven accuracy.
Rada 215-t3 bc models only:
1. Remove the blanking plug, unscrew the
grubscrew using a 2.5 mm hexagonal key and
pull off the temperature knob.
2. Rotate the ‘red’ locking ring anti-clockwise until
the ‘black’ knob retainer is released.
3. Remove the ‘black’ knob retainer.
All models except Rada 215-t3 bc:
1. Remove the temperature knob and indicator
trim or locking cap using a 3 mm hexagonal
key.
2. Pull off the temperature hub.
3. Using the temperature hub, rotate the spindle
until the required maximum blend temperature
is obtained at the discharge point (rotate
clockwise to decrease temperature).
If resistance is felt do not use force to turn
any further, as this can damage the internal
parts.
4. Once the desired maximum blend temperature
has been achieved, refit the hub without
disturbing the spindle.
For adjustable temperature position the hub
such that the lug is against the side of the
stop on the cartridge face, thus preventing
anticlockwise rotation past the maximum
temperature stop.
For locked temperature position the hub such
that the lug is between the stops on cartridge
face, thus preventing any rotation.

2. Periodic attention is given, when necessary, to
maintain the product in good functional order.
The Rada 215 and 222 range of thermostatic
mixing valves are designed for the minimum of
maintenance in normal use. The only serviceable
parts are the inlet filters which should be checked
and cleaned every 12 months. If a malfunction
occurs with the thermostatic cartridge then this
will necessitate a complete cartridge replacement.

Disinfection
In applications where system chemical disinfection
is practised, chlorine can be used (calculated
chlorine concentration of 50 mg/l (ppm) maximum
in water, per one hour dwell time, at service
interval frequency). Such procedures must
be conducted strictly in accordance with the
information supplied with the disinfectant and
with all relevant Guidelines/Approved Codes of
Practice.
If in any doubt as to the suitability of chemical
solutions, refer to Kohler Mira Ltd, or Local Agent.
6. Once the desired maximum blend temperature
has been achieved, refit the ‘blue’ hub without
disturbing the spindle.
For adjustable temperature position the
‘blue’ hub such that the lug is against the
side of the stop on the cartridge face, thus
preventing anticlockwise rotation past the
maximum temperature stop.
For locked temperature position the ‘blue’
hub such that the lug is between the stops on
cartridge face, thus preventing any rotation.
7. Check that blend temperature has not
altered.
8. Refit the ‘white’ hub top and secure with the
hub retaining screw.
9. Turn the ‘red’ locking ring so that the lugs are
in the vertical position.
