High limit safety cut-out
1.
Open the control unit cover panel.
2.
Fit the display panel. When doing this, fold the rib-
bon cable upwards
in front of
the control unit
enclosure.
Note
Do
not
kink the ribbon cable inside the control unit
enclosure.
3.
Pull the thermal insulation forwards by hand and
hold it tight.
4.
Seal in and install the sensor well for the thermally
activated safety valve.
5.
Insert the thermally activated safety valve sensor
(not included in standard delivery) as far as it will
go.
6.
Push the supplied corrugated hose completely
over the high limit safety cut-out sensor capillaries.
Note
The corrugated hose protects the capillaries from
damage and kinking.
7.
Pull the thermal insulation forwards by hand.
Thread the sensors through the holes in the ther-
mal insulation mat.
8.
Push the flow temperature sensor and sensor for
high limit safety cut-out into the sensor well as far
as they will go.
!
Please note
Damaged capillary tubes will result in faulty
sensor function
■
Never kink the capillary tubes.
■
When routing, ensure a minimum radius of
5 mm.
9.
Secure the sensors with clips.
