Remove knob. Older units are equipped with
turning knobs incl. threaded bolt. Loosen it
before exchanging.
-
Unscrew the attachment screws from the
regulator thermostat.
-
Mark the pin connections of the thermostat in
accordance with the pin number and then
disconnect.
-
Remove the thermostatic sensor from the
tub. In order to do this, carefully remove the
silicone rubber from the aluminium push-in
link of the thermostatic sensor using a knife
and tweezers, pull the sensor out of
the push-in link with flat pliers turning
slightly while doing so.
The capillary tube connects the thermostatic
sensor with the thermostat, remove the
capillary tube carefully
from the case, do not bend it under
any circumstances.
-
The assembly is carried out in reverse order. Fix the thermostatic
sensor with silicone rubber E 41.
Attach the capillary tube to the housing using silicone rubber E 41 in such a manner that it does not
come into contact with live parts or the transducers.
-
Connect the pins again in the right order.
IMPORTANT: Do not damage the thermostatic sensor or the capillary tube.
4. 4. 7 Assembly of oscillating tub and housing
-
Fill the cleaned tub edge with compound "Terostat 931 - self levelling" (even and horizontal plate).
-
Put the housing onto the tub.
-
Allow compound to cure for 24 hours.
-
Stick the thermostatic sensor of the regulating thermostat back into place using silicone rubber or
insert the regulating thermostat.
-
Assemble the drain again (page 8).
Screwed drain
At the factory all threads are sealed with liquid thread seals DELO ML No.119 (blue). The nuts are
to be secured with screw securing liquid (blue) DELO ML No.121. The threads are pre-cleaned
using spray cleanser DELOthen NK 1. Curing time is decreased by pre-treating the threads with the
activator DELOquick 32. If the sealing agents are not available during assembly, you can also use
PTFE
tape.
- Screw the bended pipe 2 onto the screw neck 1 on the tub.
- Put the washer 8 and the niro nuts 9 and 10 onto the threaded pipe 4. Lock the nuts.
- Push the threaded pipe 4 through the housing 7, put the washer 6 on, screw on the nuts 3 and 5.
- Screw the threaded pipe 4 into the bended pipe 2, fix it with the nuts 9 and 10.
- Lock the nut 3 against the bended pipe 2.
- Lock the nuts 5 and 9 against the housing 7.
- Screw on the ball cock.
- Lock the nut 10 against the ball cock.
