5.1 INTRODUCTION
This thermostatic mixer with proximity sensor is manufactured to the highest standards and has approval to
AS4032.4 which permits it to be installed in healthcare establishments such as hospitals, nursing homes and
residential care homes. When installed in healthcare establishments the supply conditions detailed in Table 2
must be observed and the commissioning and servicing requirements detailed on section 8.0 & 10.0 must be
followed.
5.2 SUPPLY PRESSURE REQUIREMENTS
This mixer is designed to be installed on all types of plumbing systems. Hot and cold water supply pressures
should be reasonably balanced; however, the mixer will function within specification on unequal pressures up
to 10:1. The mixer has integral isolating valves which permit servicing of the strainer, check valve/flow regulator
and thermostatic cartridge. They are also used for thermal disinfection. The minimum pressure for the correct
thermal operation is 30kPa. However, to achieve an acceptable flow performance at very low pressures it may
be necessary to remove the combined check valve and flow regulators and replace them with simple check
valves to facilitate thermal disinfection.

7.0 INSTALLATION
The CliniMix®CMV2 Wall Mounted Hands Free Point Use mixing valves must be installed using the appropriate
Standard, Code of Practice and legislation applicable to point of install.
The CliniMix®CMV2 Wall Mounted Hands Free Point Use mixingvalves must be installed by a licensed plumber.
If the valve is not installed correctly then it will not function correctly and may put the user in danger. It may also
void the warranty of the valve.
Prior to the installation of the valve, the system must be checked to ensure that the system operating conditions
fall within the recommended operating range of the CliniMix®CMV2 Wall Mounted Hands Free Point Use mixing
valve. If the hot water supply temperature is greater than 80° Celsius, the valve may be damaged. If the
temperature of the hot water will rise above 80° Celsius a suitable temperature limiting valve must be fitted to
the hot water supply, prior to the inlet fittings. This temperature limiting valve must be installed as per the

performance from the valve it is recommended that the inlet pressures are balanced to within 10% of each other.
To ensure that the mixing valve operates correctly, it is necessary that the pipework is thoroughly flushed with
clean water before the valve is installed. This will remove any physical contaminants from the pipework, ensuring
trouble-free operation. During the flushing procedure, care should be taken to prevent water damage occurring
to the surrounding area.
The valve should be installed so it can be easily accessed for maintenance or servicing.
During installation or servicing, heat must not be applied near the mixing valve or inlet fittings, as this will damage
the valve and inlet fittings internals. Failure to comply with this requirement will damage the valve and fittings. It
will put the user at risk, and it will void the warranty of the valve.
Note: To effectively control microbial hazards during system design, installation, commissioning and maintenance, the
requirements of local legislation shall be adhered to.
Note: In some installations, certain types of tapware devices such as flick mixers and solenoid valves are used. The water pressure
may be seen to spike outside that recommended for the valve, during rapid shut off conditions with these types of devices. Even
if the spike only lasts a split second it is still considered to be outside the operating conditions and may cause the valve to operate
incorrectly. In the event that this does occur, measures must be taken to control the spike, such as the installation of an inline
pressure reducing valve directly before the valve inlets.

8.0 COMMISSIONING
Initial Test for Correct Operation
The following must be checked to ensure the correct performance of the progressive thermostatic mixer:
−the supply pressures and temperatures are within the range of operating pressures and temperatures for
the thermostatic valve.
−the supply temperatures are within the range permitted for the unit.
Please record the testing done during the commissioning and record the temperature of the hot and cold-water
supplies and the temperature of the mixed water at the full hot setting.
A calibrated digital thermometer having rapid response time with maximum temperature hold will be required to
check and set the outlet mixed temperature of the mixer.
To Commission
To test the temperature, open the valve and allow the mixed heated water to flow for at least 30 to 60 seconds
so the temperature can stabilise before taking a temperature reading at the outlet with a digital thermometer. The
flow rate should be at least 4L/min.

Shut Down Test
Once the correct outlet temperature has been achieved, the valves internal mechanism should be exercised at
least 3 times by alternately shutting off the hot and cold supplies while the mixer is set in the full hot position.
Shut Down Test 1
With the mixer still on and with both supplies turned on, allow the mixed water temperature to stabilise for at
least 15 seconds and note the outlet temperature. While holding a digital thermometer in the outlet flow, quickly
isolate the cold water supply to the valve
The outlet flow should quickly reduce to be less than 0.1L/min following the isolation. Recording of the
temperature should continue after isolation and should not exceed the maximum temperature set out in the
applicable standard or code of practice for each state.
Restore the cold-water supply to the valve. After the mixed water temperature has stabilised note the outlet
temperature ensuring the outlet temperature has re-established. The time taken to stabilise the temperature
should not exceed the maximum time set out in the applicable standard or code of practice for each state.
Shut Down Test 2
With the mixer still on and with both supplies turned on allow the flow to stabilise for at least 15 seconds and
record the temperature. Quickly isolate the hot water supply to the valve.
The outlet flow should quickly reduce to be less than 0.4L/min following the isolation. The volume of mixed water
discharged for a period of between 5-35 seconds should be measured and should not exceed the maximum
volume set out in the applicable standard or code of practice for each state.
Restore the hot water supply to the valve and measure and record the outlet temperature after the mixed water
temperature has stabilised. The time taken to stabilise the temperature should not exceed the maximum time
set out in the applicable standard or code of practice for each state.
Ensure that all details of the Commissioning Report are completed, and a copy is kept with the installer and
owner of the premises.
The valve is now commissioned, and it can be used within the technical limits of operation.
NOTE: In some installations, certain types of tapware devices such as flick mixers and solenoid valves
are used. The water pressure may be seen to spike outside that recommended for the valve, during rapid
shut off conditions with these types of devices. Even if the spike only lasts a split second it is still
considered to be outside the operating conditions and may cause the valve to operate incorrectly. In the
event that this does occur, measures must be taken to control the spike, such as the installation of an
inline pressure reducing valve directly before the valve inlets.
To ensure that the mixing valve operates correctly, it is necessary that the pipework is thoroughly flushed with
clean water before the valve is installed. This will remove any physical contaminants from the pipework, ensuring
trouble-free operation. During the flushing procedure, care should be taken to prevent water damage occurring

10.1 FREQUENCY OF REGULAR SERVICING
The purpose of servicing regularly is to monitor any changes in performance due to changes in either the system
or the product. This may highlight the need to adjust either the supply system or the product. These products
should be checked at 6 to 8 weeks and again at 12 to 15 weeks after commissioning. The results are to be
compared against original commissioning settings.
If there are no significant changes at the mixed temperature outlet then a 6 monthly servicing cycle may be
adopted. Otherwise, servicing checks should be carried out more frequently (e.g. every 4 months).
Follow the recommended maintenance procedures detailed in Section 11.0 Maintenance.
During servicing, note the following:

TMV will ensure this requirement is met. If the CliniMix®Thermostatic Mixing Valve is to be installed without the
supplied inlet control valves then it will be necessary to install a separate isolating valve, non-return valve and
strainer to both inlets to the valve.
Strainers must be fitted to prevent any particulate contamination from entering the valve. These strainers should
be 60 mesh stainless steel (0.250mm). Isolating valves are required so that the water supply to the valve can be
isolated when servicing is required. Non-return devices must also be fitted to both the hot and cold inlets to
prevent cross-contamination.
Ensure that the test plugs in the top of the inlet fittings are tight.
The valve should be installed so it can be easily accessed for maintenance or servicing.
During installation or servicing, heat must not be applied near the mixing valve or inlet fittings, as this will
damage the valve and inlet fittings internals. Failure to comply with this requirement will damage the valve and
fittings. It will put the user at risk and it will void the warranty of the valve.
Note: The CliniMix®Thermostatic Mixing Valve is intended mainly for use in applications with set
temperatures below 45° Celsius. When installed at higher set temperature, the performance may be less
than specified in AS4032.4. In such situations consideration should be given to the question of whether
an alternative device, i.e. a tempering valve approved to AS4032.2 would provide a greater margin for
safety in reducing scalding accidents.

11.2 REMOVAL AND INSPECTION OF CARTRIDGE
1. After checking that supply conditions are within the
specified parameters (Table 2. Water supply
conditions), if the mixer malfunctions or should the
test results fail to fall within the specified limits
consider replacing the cartridge with a new one
(see section 11.3 Important Notes On Debris).
Afterwards, Follow the steps in section 10.2.2
Thermostatic Cartridge to remove and inspect
cartridge.
2. Set the temperature as per step 5 in section 11.1
MIXED WATER TEMPERATURE
ADJUSTMENT.
3. Re-commission the mixer as per commissioning procedure
(See section 8.0 Commissioning). Record the mixed water temperature.
11.3 IMPORTANT NOTES ON DEBRIS
Although this product is protected by built-in filters, debris can still find its way to the thermostat housing area.
This can happen during servicing for example. Remove cartridge (See section 11.2 Removal And Inspection Of
Cartridge) and carry out an inspection.
11.4 MAINTENANCE CLEANING
On a regular basis the anti-splash nozzle should be inspected and cleaned if necessary. This should be done
immediately before sterilising is carried out.
