General Warnings And Safety; Switching On The Appliance - Beretta Junior Green C.S.I. Installer And User Manual

USER GUIDE
1a GENERAL WARNINGS AND SAFETY
The instruction manual is an integral part of the product and it must
therefore be kept carefully and must accompany the appliance; if the
manual is lost or damaged, another copy must be requested from the
Technical Assistance Service.
Boiler installation and any other assistance and maintenance opera-
tions must be carried out by qualifi ed personnel according to the
provisions of local legislation.
For installation, it is advisable to contact specialised personnel.
The boiler must only be used for the application foreseen by the
manufacturer. The manufacturer shall not be liable for any damage
to persons, animals or property due to errors in installation, calibra-
tion, maintenance or due to improper use.
The safety and automatic adjustment devices must not be modifi ed,
during the system life cycle, by the manufacturer or supplier.
This appliance produces hot water, therefore it must be connected
to a heating system and/or a domestic hot water mains, compatible
with its performance and output.
In case of water leakage, close the water supply and contact the
Technical Assistance Service immediately.
In case of absence for long periods time, close the gas supply and
switch off the electrical supply main switch. If there is a risk of frost,
drain the boiler.
From time to time check that the operating pressure of the hydraulic
system does not go below 1 bar.
In case of failure and/or malfunctioning, deactivate the appliance,
and do not try to repair or operate directly on it.
Appliance maintenance must be carried out at least once a year:
scheduling it with the Technical Assistance Service will avoid wasting
time and money.
When the product reaches the end of its life it should not be disposed
of as solid urban waste but should be brought to a separated waste
collection facility.
Boiler use requires strict observation of some basic safety rules:
Do not use the appliance in any manner other than its intended
purpose.
It is dangerous to touch the appliance with wet or damp body parts
and/or when barefoot.
Under no circumstances cover the intake grids, dissipation grids
and ventilation vents in the installation room with cloths, paper or
any other material.
Do not use electrical switches, telephone or any other object that
causes sparks if there is a smell of gas. Ventilate the room by open-
ing doors and windows and close the central gas tap.
Do not place anything in the boiler.
Do not perform any cleaning operation if the appliance is not discon-
nected from the mains power supply.
Do not cover or reduce ventilation opening of the room where the
generator is installed.
Do not leave containers and infl ammable products in the installation
room.
Do not attempt to repair the appliance in case of failure and/or
malfunctioning.
It is dangerous to pull or twist the electric cables.
Children or unskilled persons must not use the appliance.
Do not carry out operations on sealed elements.
For better use, remember that:
- periodic external cleaning with soapy water not only improves its appear-
ance but also preserves panelling from corrosion, extending its life cycle;
- if the wall-mounted boiler is enclosed in a hanging unit, leave at least 5
cm for ventilation and maintenance;
- installation of a room thermostat will greatly improve comfort, a more
rational use of the heat and energy saving; the boiler can also be con-
nected to a programmable timer in order to control the switching on and
off of the appliance during the day or week.
2a SWITCHING ON THE APPLIANCE
Every time the appliance is powered up, a series of data is shown on
the display including the flue gas sensor meter reading (-C- XX) (see
paragraph 4.3 - fault A09); the automatic purge cycle then starts, lasting
around 2 minutes. During this phase, the three LEDs light up alternately
and the symbol is shown on the monitor (fig. 25).
To start up the boiler it is necessary to carry out the following operations:
- power the boiler
- open the gas tap to allow the fl ow of fuel
- set the room thermostat to the required temperature (~20°C)
- turn the mode selector to the desired position:
Winter mode: by turning the mode selector (fi g. 27) in the area divided into
segments, the boiler provides domestic hot water and heating. If there is
a heat request, the boiler switches on and the boiler status indicator LED
lights up with a fi xed green light. The digital monitor indicates the heating
water temperature (fi g. 29).
If there is a domestic hot water request, the boiler switches on and the
boiler status indicator LED lights up with a fi xed green light.
The display indicates the delivery temperature (fi g. 30).
Adjustment of the heating water temperature
To adjust the heating water temperature, turn the knob with symbol
(fi g. 27) clockwise to the area divided into segments.
Summer mode: turning the selector to the summer mode symbol
28) activates the traditional domestic hot water only function.
If there is a domestic hot water request, the boiler switches on and the
boiler status indicator LED lights up with a fi xed green light. The digital
monitor indicates the delivery temperature (fi g.30).
Pre-heating (faster hot water): turning the domestic hot water tempera-
ture adjustment knob to the
function. Bring the domestic hot water temperature adjustment knob back
to the required position. This function keeps the water in the domestic hot
water exchanger hot, to reduce standby times when a request is made.
When the pre-heating function is enabled, the yellow LED next to the
symbol is lit. The monitor indicates the delivery temperature of the heating
water or the domestic hot water, according to the current request.
During burner ignition following a pre-heating request, the monitor indi-
cates the symbol. To deactivate the pre-heating function, rotate the
domestic hot water temperature adjustment knob back to the
The yellow LED will switch off. Bring the domestic hot water temperature
adjustment knob back to the required position.
This function cannot be activated when the boiler is OFF: function selector
(fi g.32) to (OFF).
Adjustment of domestic hot water temperature
To adjust the domestic hot water temperature (bathrooms, shower, kitchen,
etc.), turn the knob with the
numerical values between 1 (min. value 37°C) and 9 (max. value 60°C).
On the control panel, the green LED fl ashes ON for 0.5 seconds then OFF
for 3.5 seconds. The boiler is standby status until, after a heat request,
the burner switches on and the indicator LED turns fi xed green to indicate
fl ame presence. The boiler continues to operate until the temperatures set
on the boiler are reached, or the heat request is met; after which it goes
back on standby. If the red LED indicator near the
the control panel lights up, this means the boiler is in temporary shutdown
status (see the chapter on Light signals and faults).
The digital monitor indicates the fault code detected (fi g. 34).
Automatic Temperature Control System function (S.A.R.A.) fi g. 35
Setting the heating water temperature selector to the area marked "AUTO",
activates the automatic temperature control system (frequency 0.1 sec. on;
then 0.1 sec. off; for 0.5 seconds): according to the temperature set on the
room thermostat and the time taken to reach it, the boiler varies automati-
cally the heating water temperature reducing the operating time, allowing
greater ease of operation and energy saving. On the control panel, the
green LED fl ashes ON for 0.5 seconds, OFF for 3.5 seconds.
Reset function
To restore operation, set the function selector to
5-6 seconds then set it to the required position, checking that the red indi-
cator light is OFF. At this point the boiler will automatically start and the red
lamp switches on in green.
