Unibox E BV vario
"Unibox E BV vario" (you must refit the
protection cover after commissioning) and
place the "Unibox E BV vario" into the wall
at the desired location.
Use a pipe conduit unit to facilitate
installation.
2. Use the enclosed brackets (see section 1.2
on page 23) to align and fix the "Unibox
E BV vario".
3. Provide a branch off from the supply pipe
of the two pipe system.
4. Connect the branch pipe to the "Unibox
E BV vario". Observe the direction of flow
marked on the valve body.
5. Lay the surface heating circuit starting from
the "Unibox E BV vario".
Lay the heating circuit in a spiral
pattern to achieve an even heat
distribution.
6. Provide a connection pipe from the surface
heating circuit to the return pipe of the
system.
7.

Commissioning

7.1 Filling, bleeding and leak
testing

7.2 Preliminary work for

incremental heating test

Carry out an incremental heating test to check
the correction function of the surface heating
system.
NOTICE
Damage to the screed as a re-
sult of incorrect temperatures
f Carry out the incremental heating
test of concrete and calcium sul-
phate screed in accordance with
DIN EN 1264-4.
f Observe the instructions of the
screed manufacturer.
f Adapt the flow temperature to the
surface heating system.
f Do not exceed the screed temper-
ature specified as per DIN 1264-4
near the heating pipes.
Apply heating screed complying with standards
after plastering.
Start the incremental heating test at the earli-
est:
• 21 days after laying of concrete screed
• 7 days after laying of calcium sulphate
screed
7.3 Incremental heating test
Proceed as follows during the incremental
heating test:
