Rada 320 - Mixing Valve Adjustment
1.
Remove the temperature knob screw using a 3 mm hexagonal wrench. Remove the temperature knob.
2.
Pull off the black polymer hub assembly which may inadvertently remain attached to the inside of the temperature
control handle. This is a “push fit” and can be “levered” out using a thin blade screwdriver or pliers.
3.
Rotate the spindle until required maximum blend temperature is obtained at outlet point (clockwise = decrease
temperature, counterclockwise = increase temperature).
When resistance is felt do not use force to turn any further, as this can damage the internal parts.
4.
Once the desired maximum blend temperature is achieved, re-fit the hub without disturbing the spindle: Position the
hub so that the hub stop comes up against the cartridge stop preventing any further rotation in a counterclockwise
direction. Check that blend temperature has not altered.
5.
Refit the temperature knob. Make sure that the indicator points to 9 o’clock.
