Location and Mounting
T6031 Thermostats mount either vertically or horizontally on a
wall or panel. The remote bulb can be located as far from
controller as capillary tubing allows. The bulb should be located
where it senses the average temperature of the medium to be
controlled.
Fig. 5. Bulb strapped to supply water pipe with 105900
T-clamp.
Mounting Sensing Elements
T6031E,G,H models—install bulb in return airflow.
T6031G,H,J models—install bulb in water supply where water
of average temperatures circulates around it The bulb may be
strapped to a water pipe using a 105900 Clamp (see Fig. 5) or
as follows:
1. Secure controller bulb to pipe with duct hanger wire or
metal hose clamps (Fig 6. top).
CAUTION
Do not over tighten clamps to point of distorting sensor
bulb. Over tightening clamps will cause a significant
shift in bulb calibration
(Steps 2 and 3 are optional and are to be used when large
fluctuations in the ambient temperature occur near the pipe)
2. Cover bulb and pipe with foam rubber insulation extend-
ing at least 6 in. (152 mm) beyond both ends of bulb (Fig.
6, bottom).
3. Secure foam rubber with duct tape. DO NOT ALLOW
DUCT TAPE TO CONTACT PIPE.
