SAFETY : WARNINGS
Rada products are precision engineered and should give continued superior and
safe performance, provided:
1. They are installed, commissioned, operated and maintained in accordance with
the recommendations given in this Manual.
2. Type 3 Valves are only used for applications covered by their approved
designations refer to the TMV3 Requirements Manual..
3. Anyone who may have difculty understanding or operating the controls should
be attended when showering/bathing. Particular consideration should be given
to the young, the elderly, the inrm or anyone inexperienced in the correct
operation of the controls.
4. The use of the word ‘failsafe’ to describe the function of a Thermostatic Mixing
Valve is both incorrect and misleading. In keeping with every other mechanism
it cannot be considered as being functionally infallible.
5. Provided that the Thermostatic Mixing Valve is installed, commissioned, operated
within the specication limits and maintained according to this Manual, the risk
of malfunction, if not eliminated, is considerably reduced.
6. Malfunction of Thermostatic Mixing Valves is almost always progressive in
nature and will be detected by the use of proper temperature checking and
maintenance routines.
7. Certain types of system can result in the Thermostatic Mixing Valve having
excessive ‘dead-legs’ of pipework. Others allow an auxiliary cold water supply to
be added to the mixed water from the mixing valve. Such systems can disguise
the onset of Thermostatic Mixing Valve malfunction.
8. Ultimately, the user or attendant must exercise due diligence to make sure that
the delivery of warm water is at a stable, safe temperature. This is particularly
important in such healthcare procedures as supervised bathing of patients
unable to respond immediately to unsafe temperatures.

Rada Autotherm-3 is a fully Thermostatic Bath and Shower Mixer with an integral
Flow Control and Divertor. It is recommended that Rada Autotherm-3 Shower Fittings
are used with this BSM to optimise performance (refer to section: 'Accessories').
Weight
Autotherm-3 BSM: 6.3 Kg.
Temperature Control
Temperature selection range: full cold to full hot or max temperature limit.
Note: The BSM is preset to a maximum temperature of 43°C - 45°C for the bath
ll. It is important to check the maximum temperature during commissioning as the
setting will change with different supply conditions.
Thermostatic Temperature Control: 35°C - 45°C
Note: Optimum performance is obtained when a temperature differential of 20°C
or more exists between blend and either supply (i.e. 40°C blend set, cold water
temperature maximum 20°C, hot water minimum 60°C). To make sure that the BSM
shuts off the hot supply if the cold supply fails to prevent scalding, the minimum hot
water temperature must be 12°C above the blend temperature set ( i.e. 44°C blend
set minimum hot water temperature 56°C).
Flow Control
The BSM has an integral Flow Control and Divertor. No other type of user accessible
Flow Control should be tted to the Shower Outlet. Flow Regulators are tted to
control the ow at high pressures. For pressures below 1.0 Bar it is recommended that
the Flow Regulators are removed, refer to section: 'Flow Regulator Removal'.

8
Operating Parameters
For Type 3 installations, valves are only to be used for applications covered by their
approved designations, refer to the TMV3 Requirements Manual.
Inlet Supply Pressure
Maintained Inlet Pressures: 0.2 - 5 Bar
Max. Static Pressures: 10 Bar
Note: With low pressure systems (below 1 Bar) it may be necessary to remove the
Flow Regulators tted to the product as supplied, refer to section: 'Flow regulator
Removal'. Both hot and cold pressures should be nominally balanced within ± 10%.
Inlet Supply Temperature
Recommended Hot Temperature: 55°C - 65°C
Recommended Cold Temperature: 5°C - 20°C.
Note: The BSM can operate at temperatures up to 90°C for short periods without
damage. However for safety reasons it is recommended that the maximum hot water
temperatures is limited to 65°C.
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.

INSTALLATION
General
The Installation must be carried out in accordance with these instructions, and must
be conducted by designated, qualied and competent personnel.
1. The installation must comply with the "water Supply Regulations 1999 (Water
Fittings)" or any particular regulations and practices, specied by the local water
company or water undertakers.
2. Before commencing, make sure that the installation conditions comply with
the information given in section 'Specications'. For Type 3 valves, see also
installation conditions in the TMV3 Requirements Manual.
3. Care must be taken during installation to prevent any risk of injury or
damage.
4. Isolating Valves are combined with the Flexible Hoses and should be positioned
for easy access when servicing the BSM.
5. To eliminate pipe debris it is essential that supply pipes are thoroughly ushed
through before connection to the BSM.
6. Pipework dead-legs should be kept to a minimum.
7. Supply pipework layout should be arranged to minimise the effect of hydraulic
restriction or other system usage upon the dynamic pressures at the BSM inlets.
Recommended minimum supply-line pipe diameter is 22 mm or 3/4".
8. Systems which provide maintained supply pressures in excess of 5 Bar must
be tted with suitable pressure reduction equipment to balance the system
pressures at an appropriate level.
9. Inlet pressure tappings which allow measurement of the inlet pressures to the
BSM under operating conditions are particularly recommended for healthcare
applications with Type 3 Valves. Available as an optional accessory, refer to
section: 'Accessories'.
Important!
Three Flow Regulators are supplied tted to the product. These are required to
limit the ow rate to the bath and shower when installed on high pressure systems
(> 1 Bar). On low pressure systems these may need to be removed to increase the
ow. Refer to section: 'Flow Regulator Removal'.
For combination boilers only, a fourth (white) Flow Regulator is supplied with the
product to make sure that the boiler can supply the Rada Autotherm-3 BSM with an
adequate supply of hot water. This must be tted in the hot inlet, refer to section:
'Flow Regulator Removal'.
The tting of this Flow Regulator will render the Rada Autotherm-3 outside
the scope of the TMV3 scheme.

Installing the BSM
1. The Rada Autotherm-3 BSM can be installed on most standard baths and deck
surfaces (refer to illustration).
2. Fit the Bath Sealing Gasket to the BSM with the arrow pointing forward. Carefully
position on the bath (refer to illustration).
Note: Make sure that the Gasket provides an adequate seal. If the BSM
overhangs the 'roll' of the bath then silicone sealant must be used.
3. Fit the two Backnut Adaptors and the two 3/4" BSP Backnuts and tighten. Take
care to prevent damage to the bath.
4. Fit the Flexible Hoses (supplied) to the BSM using the Sealing Washers
provided.
5. Thoroughly ush out the incoming hot and cold water supplies before nal
connection of the BSM.
6. Connect the hot and cold water supplies with the 22 mm compression ttings
(supplied).
Important! The hot water supply MUST be connected to the hot inlet. This is
stamped Hon the top of the Manifold. Reversed connections could be dangerous
to the person using the BSM. The connections, when viewed from the front, are:
Hot – left, Cold – right

7. For low pressure systems only, make sure that you remove the three Flow
Regulators tted to the hot and cold inlets and the shower outlet. This will make
sure that the highest possible ow rate is achieved, refer to section: 'Flow
Regulator Removal'.
8. For combination boilers only, a fourth (white) Flow Regulator is supplied with
the product to make sure that the boiler can supply the Rada Autotherm-3 BSM
with an adequate supply of hot water. This must be tted in the hot inlet, refer
to section: 'Flow Regulator Removal'.
The tting of this Flow Regulator will render the Rada Autotherm-3 outside
the scope of the TMV3 scheme.
In this case the thermostatic performance of the Rada Autotherm-3 will remain
unaffected but the delivery ow rates may be reduced due to the operating
nature of combination boilers.
9. Check the installation for any leaks. Fully open the Isolating Valves tted to the
Flexible Hoses.
10. Install the Shower Fittings, refer to the appropriate section in the Shower Fittings
Installation and User Guide.
11. Connect the Shower Hose to the shower outlet of the BSM.
12. This completes the installation of the Rada Autotherm-3 BSM.
Note: Following the installation, commissioning checks must be carried out,
refer to section: 'Commissioning'.

12
OPERATION
Temperature Control Knob
The Rada Autotherm-3 BSM is tted with a separate On / Off Flow Divertor Lever
and Temperature Control Knob which operate as follows:
1. On / Off Flow Divertor
From the Off position, anticlockwise movement immediately turns on the ow
to bath mode, clockwise movement diverts the ow to shower mode.
When diverting from bath mode to shower mode the maximum preset temperature
will be reduced by approximately 3°C, e.g. 44°C to 41°C.
When diverting from shower mode to bath mode the temperature will remain
below 41°C until adjusted by the Temperature Control.
The ow rate is determined by the supply pressures at the inlets of the product
control, or by the effective output power of the gas heater appliance. Flow rates
for gas water heaters and combination boilers can vary typically between 8 l/min
(winter) and 15 l/min (summer).
Note: An amount of water may be retained in the bath spout after the Flow
Control has been turned off. This will drain over a short period of time.
2. Temperature Control
In either the shower or bath ll mode, adjustment of temperature is achieved
by clockwise rotation for cooler and anticlockwise rotation for warmer up to the
preset maximum.

COMMISSIONING
Commissioning Checks
After completing the installation the following commissioning checks must be carried
out:
Note: Thermostatic mixing valves with wax capsules could 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,
turn on the Flow Divertor Lever to bath mode.
(b) Turn the Temperature Control Knob rapidly from cold to hot and back
to cold several times, pausing at each extreme.
Maximum Temperature
Note: For Type 3 valves in healthcare installations the maximum blend temperature
is determined by the application, refer to the TMV3 Requirements Manual.
The maximum blend temperature through the bath or shower outlet should be
limited to prevent accidental selection of a temperature which may be too hot. All
Rada Thermostatic Mixing Valves are fully performance tested individually and the
maximum temperature for the Autotherm-3 BSM is pre-set under ideal installation
conditions at the factory to approximately 44°C for bath ll and 41°C for showering.
Site conditions may dictate that the maximum temperature has to be re-set following
installation or servicing.
To check the temperature:
1. Turn the Flow Divertor Lever to bath mode and run for several minutes in order
to stabilise the temperature. Make sure that the hot and cold water supplies are
within Rada recommendations. Refer to section: 'Specications'.
2. Turn the Temperature Control Knob to the hot position (fully anticlockwise)
the water temperature from the bath outlet is factory set at approximately
44°C. (To re-set the maximum temperature refer to section: 'Maximum
Temperature Setting'). The actual temperature may vary depending on the
supply conditions.
3. Turn the Flow Divertor Lever to shower mode (Check that an adequate spray
pattern is delivered from the shower head) and measure shower temperature.
This is automatically re-set when the Flow Divertor Lever is turned to shower
mode and is set below 41°C.
4. Turn the Flow Divertor Lever to the OFF position.
Note: Draining of residual water held in the outlet ttings, may continue for a
period after the ow is shut off.

14
Maximum Temperature Setting
Note: For Type 3 valves in healthcare installations the maximum blend temperature
is determined by the application, refer to the TMV3 Requirements Manual.
1. Remove the Blanking Plug, unscrew the Grubscrew and remove the Temperature
Control Knob.
2. Unscrew the Hub Screw using a 3 mm hexagonal wrench (supplied) and remove
the Temperature Control Hub.
3. Rotate the Flow Divertor Lever to bath mode.
4. Rotate the Temperature Cartridge Spindle using the Temperature Control Hub
until a bath outlet temperature of 44°C is obtained from the bath spout.
(clockwise = decrease temperature).
5. Once the desired maximum blend temperature has been achieved, ret the
Temperature Control Hub without disturbing the Spindle, positioning the Hub
such that the Lug on the Temperature Hub is against the left hand side of the
Temperature Stop Sleeve (refer to illustration). Check that the blend temperature
has not altered and tighten the Hub Screw.
6. Ret the Temperature Control Knob, tighten the Grubscrew and Ret the Blanking
Plug.

17
MAINTENANCE
Rada products are precision engineered to provide satisfactory performance provided
they are installed and operated in accordance with the recommendations contained
in this guide.
The Autotherm-3 BSM is designed for the minimum of maintenance in normal use.
If a malfunction occurs with either the Temperature Control Cartridge or the Flow
Divertor Cartridge then this will necessitate a complete Cartridge replacement.
Note: The Cartridge's contains no internally serviceable parts.
When installed in very hard water areas (above 200 p.p.m. temporary hardness)
your installer may advise the installation of a water treatment device to reduce the
effects of limescale formation.
The designed service life of the service-free Thermostatic Cartridge is ve years,
providing the Autotherm-3 BSM is operated with the recommended operating
conditions. However, when supply conditions and/or usage patterns do not conform
to the recommended operating parameters and/or the recommended operating
conditions, the Thermostatic Unit and other critical parts may need to be replaced
more frequently (refer to section: 'Specications' for recommended operating
conditions).
Important! In healthcare applications such as hospitals, aged person facilities,
residential care homes and in any other applications where the user is similarly at
risk, irrespective of supply and usage conditions or the evidence of in-service tests,
the service-free Thermostatic Cartridge should be replaced at intervals of no more
than three years.
Planned Maintenance
Malfunction of Thermostatic Mixing Valves is almost always progressive in nature
and will be detected by the use of proper temperature checking and maintenance
routines.
Certain types of system can result in the valve having excessive ‘dead-legs’ of
pipework, or auxiliary cold water supply added to the mixed water from the valve.
Such systems can disguise the onset of thermostatic mixing valve malfunction and
should not be used.
We recommend a preventative maintenance procedure based on site conditions
and the risk to the user. All results must be recorded in a log book.
Important! For Type 3 Valves use the In-Service Tests given in the TMV3
Requirements Manual. In the absence of any other instruction or guidance on the
means of determining the appropriate frequency of in-service testing, the procedure
contained within this guide (taken from Annex F of D08) should be used.
For other commercial installations it is recommended that the correct blend setting
is checked every 6 months and that the In-Service Test procedure is followed every
12 months.

18
Healthcare
Healthcare applications are hospitals, aged person facilities, residential care homes,
etc. and any other applications where the user is similarly at risk.
Ultimately, the user or attendant must exercise diligence to make sure that the delivery
of warm water is at a stable, safe temperature. This is particularly important in such
procedures as supervised bathing where patients are unable to respond immediately
to unsafe temperatures.
Critical Components
Irrespective of supply and usage conditions or the evidence of in-service tests, critical
components should be replaced at intervals of no more than 5 years.
Pack Number Description
462.07 Thermostatic Cartridge
Note: During the replacement of critical components, it may be necessary to replace
other non-critical components.

Flow Regulator Removal
Standard Conguration
Three Flow Regulators are tted to the product. The Pink Flow Regulator tted to
the Shower Outlet on top of the Rada Autotherm-3 BSM limits the maximum ow
rate to the Shower Fitting. The Green Regulators are tted to the hot and cold inlets
for high pressure systems. To improve ow rates these can be removed if the inlet
pressure is below 1 Bar.
The Rada Autotherm-3 BSM has been approved for TMV3 installations in these
congurations.
Alternative Conguration
For combination boilers a fourth (White) Flow Regulator is supplied with the product
to make sure that the boiler can supply the Rada Autotherm-3 BSM with an adequate
supply of hot water. This must be tted in the hot inlet.
The tting of this Flow Regulator will render the Rada Autotherm-3 BSM outside
the scope of the TMV3 scheme.
In this conguration the thermostatic performance of the Rada Autotherm-3 BSM will
remain unaffected but the delivery ow rates may be reduced due to the operating
nature of combination boilers.
