NOTICE!
On installing the thermostat, follow the in-
structions described below to prevent dam-
age to the thermostat and to ensure it can
function properly:
–
The degree of protection IP 54 cannot be
met when the seals are missing or when
they are incorrectly inserted into the ther-
mostat (Fig. 1)!
Do not remove the seals in the housing
(1) and on the set point adjuster of the
temperature regulator (4).
The thermostat must only be operated
with inserted seal (6).
–
A damaged capillary will cause the mea-
suring fluid to leak out (see Table 1) lead-
ing to the permanent failure of thermostat!
Do not bend or cut the capillary. The
smallest bending radius must not be
smaller than 5 mm.
