English

The TA-MIX is a thermostatically controlled mixing valve for central mixing of the hot
water supply in homes.
• Adjustable for mixed temperatures between 35 and 65°C. N.B. Locked at 65°C from
factory.
• Made of dezinicification resistant material AMETAL
• Easy to install. Can be easily connected to smooth pipes with FPL connection,
M28x1.5 thread permitting connection to 10-22 mm pipes.
Setting of the mixed water temperature
Between maximum and minimum temperatures it is four turns on the handwheel. When
controlling the function of the mixing valves, the handwheel is to be locked at 65°C.
If you want to change the mixed water temperature, unscrew the locking screw on the
top of the handwheel, set the handwheel and lock with the screw.
Installation
Before fitting the valves, flush the lines thoroughly to remove any dirt that could affect
performance.
A heat block or check valve should be fitted in order to prevent convection.
Hot water outlets upstream of TA-MIX
Any outlet upstream of the TA-MIX valve, e.g. for dishwasher or similar, causes
temperature variations in the draw-off warm water when run at the same time. The
reason for this is that the pressure-drop through the water heater increases sharply
when hot water is drawn off, where as the pressure-drop on the cold water side up to the
mixing valve remains the same. If a hot water outlet is arranged upstream of the valve a
nonreturn valve must be fitted upstream of the mixing valve.

To prevent back-flow and building up of pressure in the cold water line, connection
should be done as shown in the sketch.
