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 the ef-
ficiency features of the appliance, in the presence
of water whose features can lead to the deposit
of limescale, installation of the "polyphosphate
dispenser" kit is recommended.

1.6 ELECTRICAL CONNECTION.

The "Caesar" water heater has an IPX5D protec-
tion 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: Immergas S.p.A. declines any respon-
sibility for damage or physical injury caused by
failure to connect the water heater to an efficient
earth system or failure to comply with the refer-
ence 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
supply cable must be connected to a 230V ±10%
/ 50Hz mains supply respecting L-N polarity
and earth connection; , this network must
also have a multi-pole circuit breaker with class
III over-voltage category. When replacing the
power supply cable, contact a qualified firm (e.g.
the Authorised After-Sales Technical Assistance
Service). The power cable must be laid as shown
(Fig. 1-3).
In the event of mains fuses replacement on the
modulation board, use a 3.15A fast fuses. For
the main power supply to the appliance, never
use adapters, multiple sockets or extension leads.
N.B.: 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.
