Immergas HYDRO 3 Instructions And Warnings page 28

1.3 PLUMBING CONNECTION.
Following the instructions further
on in the manual, install the pipes
to ensure optimal drainage and
insulate them to prevent condensate
from forming.
Incorrect drain pipes can cause water
leaks and damage the device.
1.4 WIRING.
Do not connect the fan coil to the
supply voltage until wiring has been
completed and the pipes have been
connected.
Earth the fan coil.
Do not connect the earthing cable to
the gas or water pipes, to the light-
ing cable or to the telephone earthing
wire. Incomplete earthing can cause
an electric shock.
Install an earth leakage circuit
breaker.
Failure to install this circuit breaker
can cause electric shocks.
Install the indoor units, wire the sup-
ply voltage and connect the cables at
a minimum of 1 metre from the tel-
evision or radio so as to prevent in-
terferences or noises in the images.
Based on the type of radio waves, a
distance of 1 metre may not be far
enough to completely eliminate the
noise.
For electrical work, comply with the
national and local regulations on
wiring and follow these installation
instructions. Use a dedicated electri-
cal circuit for power.
If the capacity of the electrical circuit
is insufficient or is faulty, this could
cause an electric shock or a fire.
Use the specified cable, connect it
and fasten it firmly to prevent any
external force from interfering on
the terminal.
Incorrect connection or improper fas-
tening of the wire may result in over-
heating or a connection fire.

Prepare the wiring traces properly
so that the control panel cover can
be correctly fixed.
Incorrect fastening of the control pan-
el cover can cause overheating at the
terminal connection point, a fire or an
electric shock.
If the power cable is damaged, it
must be replaced by the manu-
facturer, by one of its specialised
technicians, or by another qualified
person.
An all-pole disconnect switch with
a contact distance of at least 3 mm
on all poles must be used in the wir-
ing with nominal current operating
values of at least 10mA, in compli-
ance with national legislation.
