to the instructions of the designer. The heaters are
provided with threaded connections listed in the tables
of dimensions on page . 6 .
It is advisable not to connect the unit heaters with pipe
diameters of less than those of their attacks .
- Provide the outgoing tube an automatic air
discharge valve .
- It is recommended to mount attacks on a shut

7.0 ELECTRICAL CONNECTIONS
WARNING! Make the electrical connections
with power off and only after completing the
plumbing connections and have verified the proper
maintenance .
Make sure that the available electrical power is the
type 230 V - single phase - 50 Hz .
Mount close to the appliance an all-pole switch with
adequate capacity (with a contact gap of at least 3
mm) for any general standstill.
The use of gas and / or water pipes for the appliance
to be earthed is not allowed. The manufacturer is
not liable for any damage caused by failure to earth
the appliance and failure to comply with the wiring
diagrams .
Insert the power cable through the cable clamp ,
taking care to cut the conductors so that the earth
yellow / green cable is longer than the other two. This
precaution , in case of accidental detachment, enables
the earth cable to exit for last from the connections.
The power cord must be suitable for the type of
system implemented and will have a size suitable to
Flow
seal the cable gland ( we recommend the type H05
VVF 3x1.5 mm
Flow
Connect the power cord to the phase terminals ( L),
neutral ( N ) and the earth terminal block under .
