CHECKING / SERVICING THE MIXING VALVE
Note that this thermostatic mixing valve is a SAFETY
VALVE. We recommend that the valve is checked at least
once per year to ensure its continued function. For instal-
lations with poor or unknown water quality, or other ad-
verse supply conditions, it may be necessary to check the
valve at more frequent intervals.
The temperature should be checked at the same outlet as was used for
commissioning in the first instance. If the temperature is more than 5°F
(3°C )from the commissioning temperature, refer to the trouble shooting
guide in Section 4.
There may be some variation in the temperature of the water from the
thermostatic mixing valve due to seasonal temperature variations in the
cold water supply.
The check valve can be easily accessed for cleaning by removing the un-
ions.
