The control unit is pre-assembled and leak tested at
works.
The control unit is supplied for left hand side con-
nection.
For right hand side connection, turn the complete con-
trol unit vertically. Now turn pump in such a way that
the motor is pointing forward. Loosen collar nuts at
the pump. Turn pump by 180° and re-tighten collar
nuts firmly.
Screw control unit firmly onto the stainless steel dis-
tributor/collector. When installing the distributors/col-
lectors with 2 and 3 heating circuit connections, mount
the bracket supplied with the control unit as additional
bracket (see illustr. 5.1 and part 5, illustr. 6.1).
When mounting the control unit inside a cabinet,
please observe paragraph 4.2 "Dimensions/connection
size".
To mount the angle pattern adapter, remove the pro-
tection caps of the three-way valve.
Screw the angle pattern adapter onto the three-way
valve. The threaded connection of the adapter should
point forward.
Install the components of the flow temperature regu-
lating set (see illustr. 5.2 and paragraph 8 "Accesso-
ries") according to the installation instructions.
DANGER
The power supply must be switched off before
work commences.
Observe warning advice under paragraph 2

CAUTION
– Do not use any lubricant or oil when installing
the valve as these may destroy the seals. If ne-
cessary, all dirt particles and lubricant or oil re-
sidues must be removed from the pipework by
flushing the latter.
– When choosing the operating fluid, the latest
technical development has to be considered (e.g.
VDI 2035).
