Application
Surface mounted thermostatic mixers are designed for
hot water supply via pressurized storage heater and
utilized in this way provide the best temperature
accuracy.
Thermostats cannot be used in connection with low
pressure storage heaters.
All thermostats are adjusted in the plant at a flow
pressure on both sides of 45 psi.
If temperature deviations should exist due to special
installation conditions, then the thermostat is to be
adjusted to the local conditions (see Adjustment).

Minimum flow rate
At a flow pressure over 72.5 psi it is recommended that
a pressure reducing valve be fitted in the supply line.

Installation
Flush pipes thoroughly!
Install S-unions and fit mixer, for required
dimensions, see fold-out page I, fig. [1].
1. Install the S-unions and sleeve, preassembled with
the escutcheon.
2. Screw-mount the mixer and check connections for
leakage.
3. Push the sleeve with escutcheon onto the union nut.
4. Screw the escutcheon flush against the wall.
Refer to the dimensional drawing on fold-out page I.

4. Pull off temperature control handle (D).
5. Turn adjusting nut (E) until the water temperature
reaches 100 °F.

Temperature limitation
The safety stop limits the temperature range
to 100 °F.
If a higher temperature is desired, the 100 °F limit can
be overridden by pressing the button (G).
