Any intervention on the de-
vice, including disposal, must
be performed by qualified per-
sonnel with a suitable Refrig-
eration Technician's Licence
aimed at the knowledge and
management of systems con-
taining HC type gases such as
R290 (Propane).
OBLIGATION
R290
During the design and con-
struction phase of the sys-
tems, local rules and regula-
tions must be complied with.
The air inlet and outlet of the
appliance must be channelled
to the external environment as
indicated in paragraph 6.6 on
There is a risk of explosion in case of refrigerant gas leaks.
• Ventilate the installation environment.
• Do not use open flames
(e.g. lighters, matches).
• Do not smoke
.
• Do not use components or devices
that may generate
sparks (for example: do not turn lights on by switches, do
not connect electrical equipment, etc.).
• Leave the building immediately, prevent other people from
accessing and contact the emergency personnel.
►
DANGER OF DEATH DUE TO
CHANGES TO THE PRODUCT OR
THE INSTALLATION ENVIRONMENT
• Do not install the device
in conditions other than those
described in this manual (ref. chapter 6 on page 95).
• Never remove, tamper with, bypass or block
the safety
devices.
• Do not remove or destroy any seal
applied to compo-
nents.
• Do not make
changes:
- to the product
- to the water and electricity networks
- to the drain pipes.
►
DANGER OF BURNS DUE TO HIGH
TEMPERATURES
The protruding hoses and hydraulic connections become very
hot during operation.
• Do not touch
the hydraulic connections.
• Do not touch
the air inlet and outlet points.
Domestic hot water heated to temperatures above 50 °C can
cause scalding during use (shower, sink, etc.).
Even lower temperatures can be dangerous for children and
the elderly.
It is always recommended to install a mixing valve in the outlet
connection of the water heater and to set an operating temper-
ature that is not too high.
►
AVOID THE RISK OF INJURY AND
DAMAGE TO THE ENVIRONMENT
DUE TO ACCIDENTAL LEAKAGE OF
THE REFRIGERANT GAS
The equipment contains R290 refrigerant gas.
It is an ecological refrigerant gas, which has a low environ-
mental impact and does not damage the earth's ozone layer;
however, in the event of an accidental gas leak:
• do not touch
any part of the product;
• do not inhale
vapours or gases.
Call a physician immediately if you come into contact with
the refrigerant gas.
The refrigerant gas must not be released into the atmos-
phere.
Before disposing of the device, the refrigerant gas contained
in it must be poured into a suitable container to be recycled or
disposed of in accordance with current regulations.
