Operations For Commissioning - MBM FRG74A Manuel D'installation Et D'utilisation

GENERAL WARNINGS
Operators have a duty to familiari-
se themselves adequately, using
this manual before performing
any intervention, adopting the specific
safety requirements to make every kind
of human-computer interaction safe.
Any technical modification that af-
fects the operation or safety of the
machine must only be carried out
by the technical personnel of the manu-
facturer or by technicians that are for-
mally authorised by the manufacturer.
Failure to do so exempts the manu-
facturer from any liability for for any pos-
sible resulting modifications or damage.
Even after appropriate familiarisa-
tion, upon the first use of the ap-
pliance, in any case simulate a
number of test operations to save more
rapidly the main functions of the ap-
pliance, e.g. start-up, shut-down, etc.
The appliance is provided already
tested by the manufacturer and
fitted with the type of gas and
electrical supply specified on the rating
plate applies.
In case of supply with LPG
gas (Butane or Propane) at 50
mbar, a pressure stabilizer 50 mbar
must be installed upstream of the
appliance.
FIRST COMMISSIONING
UP / Upon completion of the opera-
tions of positioning and connection to
the power sources, perform a series of
operations such as:
1. Cleaning away of the protective ma-
terials (oils, grease, silicones, etc.) insi-
de and outside of the cooking chamber
(see section 3 / Removal of protective
materials).
2. General checks and controls such as:
Check opening of switches & network
gate valves (water, electricity, gas

when applicable); Checking of drains;
Checking and monitoring of the exter-
nal fumes/vapour extraction; Checking
and monitoring of the protection panels
(all the panels must be fitted correctly).
CONTROL AND REGULATION OF
THE GROUPS GAS SUPPLY /
With the connection opera-
tions described in the pre-
vious sections completed, the
appliance, even if correctly calibra-
ted during the testing phase, requi-
res partial verification of the para-
meters set directly at the place of
final destination.
The first parameter to be
checked allows verification
via the type of power supplied
by the body dispensing the correct
pressure present.
PRESSURE DETECTION
GAS INLET
If the measured pressure is
lower than the 20% compared
to the nominal pressure (ex.
G20 20 mbar ≤ 17 mbar) suspend the
installation and contact the gas di-
stribution service.
If the measured pressure is hi-
gher than the 20% compared to
the nominal pressure (ex. G20
20 mbar ≤ 25 mbar) suspend the in-
stallation and contact the gas distri-
bution service.
The constructor firm does not
recognise the machines war-
ranty in case the gas pressure
is lower or higher than the values
above described.
Make sure there are no gas leaks
After controlling the pressure
and type of gas supply interven-
tion may be required, such as: 1.
