MULTICAL® 403
4 Mounting the calculator
The MULTICAL® 403 calculator can be mounted in different ways; either direct on the flow sensor
(compact mounting), or on a wall (wall mounting).
4.1 Compact mounting
Compact mounting means that the calculator
is mounted directly on the flow sensor. Having
been mounted, the calculator is sealed
with seal and locking wire. If there is risk of
condensation (e.g. in cooling applications), the
calculator must be wall mounted. Furthermore,
MULTICAL® 403 in cooling applications must be
the condensation-proof version, type 403-C.
In case of bidirectional heat/cooling energy
metering, type 403-T is used.
The construction of MULTICAL® 403 always
provides minimum installation depth in
connection with compact mounting. Due to the
design the mounting radius in critical places
remains 60 mm, both at 45° and 90° mounting
of the flow sensor.

4.2 Wall mounting
MULTICAL® 403 can be mounted directly on an
even wall. Wall mounting requires a wall fitting
(3026-655), which is available as an accessory
to MULTICAL® 403. Use the fitting as a template
to mark and drill two 6 mm holes in the wall
and mount the fitting using the enclosed
screws and rawlplugs. Mount MULTICAL® 403
on the wall fitting by sliding the calculator
onto the fitting in the same way as it is done in
connection with compact mounting.
Note:
For q
p
3.5 flow sensors and larger it is
possible to demount the bracket from
the flow sensor and use it as a wall
bracket.
