INSTALLATION
EV02F CONTROL UNIT INSTALLATION
Fully loosen the fastening bolt to release the base of
the control unit. Lever on the slots with a screwdriver
to remove the base.
Secure the control unit terminal base to the wall (or
according to the mounting systems described in the
previous page) in a dry room, free from dripping.
EC11 OUTSIDE PROBE INSTALLATION
Install the outside probe in a vertical position on the
north or north-west wall of the building at about 2.5
metres at least from the ground. Install the probe far
from heat sources (windows, aerators, flues, etc.)
and protruding parts.
EC12 (contact probe) AND EC13 (immersion
probe) DELIVERY PROBE INSTALLATION
Install the contact probe EC12 onto the water pipe
with the clamp provided for the purpose and with heat
conducting paste interposed in order to guarantee
proper heat conduction.
The immersion probe EC13 must be fitted in the pip
-
ing with the sheath filled with mineral oil or silicone
grease.
NOTE The delivery probes must be mounted down-
stream the mixing valve at least 1.5 metres from the
valve, preferably after an elbow.
If the circulation pump is placed on the delivery side,
install the probe downstream the pump.
3- OR 4-WAY MIXING VALVE INSTALLATION
Install the mixing valve at boiler top edge level, in
handy position.
Check for no seizing between shutter and valve body
by operating the mixing valve manually; restore me
-
chanical connection between servo control and valve
body.
When at closed position the mixing valves do not
guarantee perfect seal, it is therefore necessary to
install suitable gate valves or check valves on radia-
tor circuits in order to enable valve removal without
having to drain the circuit.
