1.5 HYDRAULIC CONNECTION.
Attention:
before connecting the water heater
and so as not to make the warranty null and void
on the DHW heat exchanger, wash the system
thoroughly (piping, etc.) in a way to remove
any residue that could compromise the good
functioning of the water heater.
Water connections must be made in a rational
way using the couplings on the water heater
template.
Attention:
to preserve the duration and features
of appliance efficiency, in the presence of water
whose features can lead to the deposit of lime
scale, it is necessary to install the “polyphosphate
dispenser” kit.
If the network fuse on the connection terminal
block needs replacing, this must also be done by
qualified personnel: use a 3.15 A fast fuse. For
the main power supply to the appliance, never
use adapters, multiple sockets or extension leads.
N.B.:
all water heater pipes must never be used
to earth the electric or telephone lines. Ensure
elimination of this risk before making the water
heater electrical connections.
1.6 ELECTRICAL CONNECTION.
The “Caesar Eco” water heater has an IPX5D pro-
tection rating for the entire appliance. Electrical
safety of the appliance is reached only when it
is correctly connected to an efficient earthing
system as specified by current safety standards.
Attention:
the manufacturer declines any
responsibility for damage or physical injury
caused by failure to connect the water heater to
an efficient earth system or failure to comply with
the technical reference standards.
Also ensure that the electrical installation cor-
responds to maximum absorbed power specifi-
cations as shown on the water heater data-plate.
Water heaters are supplied complete with an
“X” type power cable without plug. The power
cable must be connected to a 230V ±10% / 50Hz
mains, respecting L-N polarity and the earthing
connection
; this network must have a mul-
ti-pole circuit breaker with Class III overvoltage
category. If the power supply cable is damaged, it
must be replaced by a special cable or assembly,
which are only available from the manufacturer
or its After-sales Service. It is recommended to
contact a qualified company (e.g. the Authorised
After-Sales Technical Assistance Service) for
replacement to avoid a hazard. The power cable
must be laid as shown
(Fig. 4)
