Vernatherm Thermostatic Mixing Valve (S01-116B) - Complete Valve
Prior to June 13, 2013
Repair kit S45-049 is pre-packaged and includes o-ring, flip ring, power element and spring.
Maintenance Instructions
1. Disassembly the Vernatherm valve, being careful not
to damage the power element. Replace the element, if
necessary.
2. An old or worn flip ring may cause temperature
fluctuation and/or water chatter. If necessary, remove the
old flip ring and replace with a new ring.
3. Reassembly the power element and valve body. Apply
grease to the main valve slide and gently ease into
position, rotating so that the grease is applied to the flip
ring. Do not force the slide as this may push the flip ring
from it's position. To test, rotate the slide; a slight drag
should be felt when correctly installed.
4. Reassembly the valve.

Service Suggestions
When servicing the Vernatherm valve, make sure it is installed in the correct position. The most common error that
occurs is when the valve is installed in the reversed position, that is, the hot line is connected to the cold line and the
cold line is connected to the hot.
A red ring is painted on the hot side of the valve.
The table below lists conditions that occur when the valve is installed correctly, and when it is in the reversed position.
