Installation
The unit can be installed basically inde-
pendent of position. However, wherever
possible, the actuator should not be
installed upside down.
■ Slide the lever into the "Open flow"
position, so that the system can first
be flushed.
■ Remove the actuator with the protec-
tive cover. This will simplify installa-
tion.
■ Allow for approx. 25 mm of space so
the servo motor can be reinstalled.
Installation
Installation may only be performed
by authorised specialists.
NOTE
! CAUTION
All connections must be made with
the unit in a de-energised state
(electrical system).
Do not use any boiler accessories,
soldering material or wet materi-
als of a mineral oil basis, or which
contain mineral oil, hydrocarbon or
ethylene glycol acetate.
If diluted with at least 50% water,
diethylene glycol, ethylene glycol
and propylene glycol can be used
(anti-freeze agent).
NOTE
If the flow of water is to be redirected, in-
stall the system such that the flow enters
through valve opening "AB" and exits
through valve opening "A" or "B".
In mixed systems, install the three-way
switching valve such that the water
enters through valve opening "A" or "B"
and exits through valve opening "AB".
■ Fit the three-way switching valve
right to the pipe itself.
■ During installation of the pipes, do
not grasp or hang on to
the actuator.
■ Steady the three-way switching valve
with your hand and tighten the pipe
connection with an open-ended
spanner or steady the valve with an
open-ended spanner and tighten the
pipe connection with an adjustable
spanner
(see diagrams on following page).
