By means of the adapters in the delivery, the device can be
installed on radiator valves of type Danfoss RA, Danfoss
RAV and Danfoss RAVL.
7.1 Removing the old dial
Rotate the thermostat dial to the maximum value (
A
) (an-
ti-clockwise). The thermostat dial then no longer presses
against the valve spindle, making it easier to remove.
There are different ways of fixing the position of the ther
-
mostat dial:
•
Union nut:
Unscrew the union nut in an anticlockwise di-
rection (B). Then you can remove the thermostat head (C).
•
Snap-on fastenings:
Thermostat dials that have been
attached using this method can be easily released by gi-
ving the lock/union nut a slight turn in the anticlockwise
direction (
B
). The thermostat dial can then be removed (
C
).
•
Compression fittings:
The thermostat dial is held in
place by a mounting ring which is held together with a
screw. Slacken this screw and remove the thermostat
dial from the valve (
C
).
•
Screwed on with a grub screw:
Slacken the grub screw
and remove the thermostat dial (
C
).
7.2 Adapter for Danfoss
One of the enclosed adapters is required for installati-
on on Danfoss valves. The arrangement of the suitable
adapter ring for the appropriate valve can be found in the
following figures:
Take care during installation that you do not trap your
fingers between the two halves of the adapter!
The Danfoss valve bodies have elongated indentations
(E)
running all around (see arrow), which also ensure better
seating of the adapter after it has been latched into place.
When installing, please ensure that the spigots inside
the adapter
(D)
are in the same position as the inden-
tations
(E)
on the valve.Latch the adapter, which cor-
responds to the valve, completely onto the valve body.
