Apex Thermostatic Mixing Valve 20mm Standard Valve - TMV20

Model: TMV20

Apex Thermostatic Mixing Valve 20mm Standard Valve - TMV20

Application:
Where water temperature control must be precise or water is required to be at safe skin contact temperature (45 degrees) e.g. hospitals, aged care, kindergartens, hair salons. Thermostatic Mixing Valves can be used for single or multiple point applications.  

Standards:

• Complies with NZBC Clause G12 (2001)
• Complies with NZS 4617:1989
• Complies with BS 7942:2000  

• Fail safe shutdown, controls tempreture, factory set to 45°C
• Outlet tempreture adjustable to 35°C to 60 °C
• High flow rate 40l/min at 500kPa
• Forged, high quality, corrosion resistant, DR brass body, nickle plated
• Integral non-returns means valve is ideal in ring main installations
• TMV20 has has internal chamfer to suit compression fittings - no union required
• TMV20BV comes with right angle ball valves for easy testing, maintenance or replacement
• TMV20 and TMV20BV both have intregral, 250 micron/60 mesh filters to ensure no debris enter the valve

Installation:

• Refer to Specifications Tab for installation guide.
• Valve to be installed by a qualified plumber.
• Installation must comply with local authority requirements.
• Valve may be installed in any orientation.
• Flush pipes prior to fitting.
• Connections are H (hot inlet) C (cold inlet) and OUT (tempered outlet).
• Do not apply heat near valve during installation.
• Do not install directly into cylinder outlet.

Caution:
Valves not installed in accordance with these instructions may result in unsafe performance.

Commissioning:

• The outlet temperature must be set on site.
• It should be set to and verified using a thermometer.
• Remove cap.
• Use a screwdriver to adjust to desired temperature with the water running.
• Turn anti-clockwise to increase the temperature.

Testing and Maintenance:

• Testing should be carried out at least every 12 months. Note that the owner, occupier or facility manager needs to be notified that testing is being carried out and measures shall be taken to ensure safety during the testing.
• Check cleanliness of strainers and non-return valves; check non-return valve operation.
• Check the discharge temperature at the nearest outlet at both high and low flow using a thermometer with an accuracy of +/- 0.5˚C. Record the test results and the location of the valve. Isolate the cold supply and check that the thermostatic mixing valve shuts down the hot supply.
• If a valve is found to be faulty during testing, it must be replaced.
• The thermostatic mixing valve shall be replaced at intervals not exceeding 5 years.
• Servicing of the internals of the valve is limited to replacement of the complete unit.
