- Page 2 The SMV-001 responds rapidly to changes in temperature and pressure in order to maintain a safe, steady showering temperature. The SMV-001 has been designed for use in UK healthcare premises as a Type 3 mixing valve under the TMV3 scheme.

2. Periodic attention is given, as necessary, to maintain the product in good functional order. The SMV-001 is designed to deliver water consistently at a safe temperature. In keeping with every other mechanism, the SMV-001 mixer cannot be considered as being functionally infallible therefore the SMV-001 mixer cannot totally replace the vigilance of nursing / supervisory staff where that is necessary. - Page 4 Components SMV-001 Mixer valve 3/4” BSP Fitting 1/2” BSP Fitting Offset Connector Temperature Lever Cold Inlet Hot Inlet BackPlate Shower Valve Outlet Flow Lever Connections: 1.

Page 5: General Information
We recommend that isolation valves (not supplied) be fitted as close as is practicable to the water supply inlets of the SMV-001 mixing valve whilst being accessible for maintenance and servicing purposes. The hot supply connection is on the left side nearest to the flow control identified with a red mark. - Page 6 Operation Adjusting the Temperature The temperature is controlled by rotating the temperature lever on the right side of the mixer. The temperature is limited to a comforatable showering level of 38°C. To obtain a higher temperature, press the override button on the temperature lever and continue to rotate the lever.
- Page 7 Procedure Check that: a) the designation of the SMV-001 mixing valve matches the intended application. b) the supply pressures are balanced and within the range of operating pressures for the designation of the valve. c) the supply temperatures are within the range permitted for the valve and by guidance information on the prevention of legionella etc.
- Page 8 Make sure that an adequate supply of hot water is available at the hot inlet of the SMV-001 Mixer. The minimum temperature of the hot water must be at least 10°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.
- Page 9 Commissioning Step 1 Adjust Temperature Setting For a TMV3 installation the maximum blended temperature should be set to 41°C. For non TMV3 installation the maximum blended temperature can be set to above 41°C. 1. Turn the temperature lever to position 38°C mark and test that the temperature of the water from the shower outlet is 38°C.
- Page 10 Commissioning 7. Finally replace without turning the lever and tighten the screw and replace cap. Re-test that the temperature of the water from the shower outlet is now 41°C. If the temperature is not 41°C then adjust the Override Limit Ring accordingly. For non TMV3 applications the Override Limit Ring may be adjusted to the desired temperature.
- Page 11 Commissioning Flow mark Override Button Limit Ring Override Limit Ring Step Flow Lever 3. Remove the Flow Lever and adjust the Limit Ring so that it is aligned with the flow mark position. This will then set the maximum Normal flow rate position before the override button is depressed.
- Page 12 Maintenance and Servicing Maintaining the Check Valves & Strainers: The Check Valves are located inside the Inlet Connector of the Shower Valve to prevent backflow, the Strainers are installed inside of the Inlet Connectors to stop the debris from entering the Shower Valve. Caution! Make sure that the Check Valves are replaced correctly, otherwise cross flow may occur.

- Page 14 IN-SERVICE TESTING The purpose of in-service testing is to regularly monitor the thermal performance of the SMV-001 Mixer valve. Deterioration in performance can indicate the need for service work to be carried out on the system. If the authority concerned does not have a planned test and maintenance schedule then the suggestions below should form the basis of a new system.
- Page 15 Conditions are outside of the specifications. Supply pressure too low - check the supply is above 0.5 bar. No flow No hot water is reaching the SMV-001 - check supply. Filters are blocked - Check filters Isolation valve is closed - check valves.
