thermostat
always
needs to be positioned in the top part of
the electric heater. This means that for some applications,
the sensor will need to be re-positioned. See figure 2.

Electric box of electric heater is at the same side of
the standard water connections of the unit. No need to
reposition the capillary bulb.
■
Non standard (horizontal installation)
Electric box of electric heater is at the opposite side of
the standard water connections of the unit.
Reposition the capillary bulb according to figure 2-2.
■
Non standard (vertical installation)
Reposition the capillary bulb on the top of the
automatic-reset safety thermostat according to
figure 2-3 and figure 2-4.
