NOTE: Some models have an adjustable tubing length
to 3 in. (76 mm). In these models, pull out extra
tubing inside the case if needed.
5. Fill the system. Make sure that the well is screwed
in tightly enough to prevent leakage. Do not tighten
after controller is secured to the well, applying
force to the case.
6. Loosen the screw (at the top of the case, above the
scale setting), and remove the cover. Loosen the
two screws that secure the adapter clamp (See
Fig. 1).
7. Determine whether vertical or horizontal mounting
method is desired; see Fig. 2 for mounting bracket
placement.
8. Insert the sensing element into the immersion well.
9. Fasten the case of the Aquastat Controller to the
well with the adapter clamp. Make certain that the
clamp is properly positioned over the groove of the
well spud. Also be sure the flange at the opening of
the well fits snugly into the opening of the case. Be
sure the sensing element bulb bottoms in the well.
