Filling The Jacket With Water; Filling The Tank; Heating; At The End Of Cooking Operations - Nordcap GRK9 Manual Del Usuario

CAUTION
Never set the equipment at work before filling the
jacket with water.
Not complying with this standard would provoke
serious damages to the tank of stainless steel and
to the other internal components for overheating.

3 - FILLING THE JACKET WITH WATER

Attention!
Every morning, when the appliance is cold, check
that water does not drop below the minimum level:
• Open the cock of minimum level "F2" from
which water must always flow.
When possible, fill the jacket with deionized water
whose hardness is not higher than 5 French degrees
carrying out the following operations:
• Remove the screw plug "E" closing the jacket port.
• Open the cock of maximum level "F1".
• Pour decalcified water through the port until a
continuous thin stream of water starts flowing out of
cock "F1".
• Screw plug "E" again carefully.
Do not load water over the maximum level.
Any overflow must be drained through the jacket
drain valve "P".
Never remove the screw plug "E" closing the
jacket port nor open the level control cocks or
other draining devices when the appliance is
working or it is still hot. Wait until its pressure
drops down to atmospheric pressure.

4 - FILLING THE TANK

• Make sure that cock "A" is closed.
• Open the two cocks "B" and "C" of hot and cold
water. The filling level will be at least 6 cm below the
overflow edge.
• Close the lid.

5 - HEATING

• Power the equipment and supply gas by turning the
switch on and acting on the valve installed before
the appliance.
• Turn the knob of switch "M" to the ON position; the
green warning light "N" will be on indicating that the
appliance is powered.
• Press and turn knob "J" counterclockwise from the
OFF position to the position of PILOT LIGHTING.
• Knob "J" will control the gas valve and it has 4
positions of use:
OFF
PILOT LIGHTING
FLAME AT MAX. POWER
FLAME AT MIN. POWER
• Press knob "J" completely and at the same time
press the button of piezoelectric lighter "K"
repeatedly: this will
Approximately 20 seconds after the ignition of pilot
light the pilot flame.
flame, release the knob: the flame must go on
burning. If this is not the case, repeat these
operations.
• The lighting of pilot burner can be observed through
inspection ports "O".
• Turning knob "J" from the position of PILOT
LIGHTING to the position of FLAME AT MAX.
POWER or of FLAME AT MIN. POWER will enable
to light the main burner.
• The pressure inside the jacket is controlled
automatically: the pressure switch provokes the
extinguishing and lighting of the burner via the
solenoid valve so that pressure is kept at an
optimum value and the consumption of jacket water
is reduced.
Note! Every time the equipment is set at work, after
10/15 minutes from the ignition allow air to escape
from the jacket by pressing the button of vent valve "I".
That will ensure an optimum pressure inside the jacket
(faster temperature rise and energy saving) because
the inside air escapes.

6 - AT THE END OF COOKING OPERATIONS

6.1 - Extinguishing the burner

• At the end of cooking operations, turn knob "J" to the
position of PILOT LIGHTING to extinguish only the
main burner.
CAUTION!
Open the lid carefully to avoid scalds due to steam
exhaust or to the contact with hot surfaces.
• Every day, when opening the lid, make sure that it is
kept lifted before releasing its handle; every six
months the balancing spring must be checked by a
skilled engineer.
However, do not put your hands under the lid
when this is lifted.
• Turning drain cock "A" will enable to drain the tank
content.
Note! Lubricate cock "A" with dietary fats regularly
once a week to prevent any break and reduce its wear.

6.2 - End of the operations

• Turn the knob of gas valve "J" to the OFF position to
extinguish the pilot burner.
• Turn the knob of switch "M" to the OFF position.
• Close the gas shutoff valve.
• Disconnect the automatic switch installed before the
equipment.

7 - SAFETY AND CHECKING DEVICES

• Pressure gauge "G" that indicates the steam
pressure in the jacket.
• Vent and vacuum valve "I" enabling the exhaust of
the air inside the jacket.
• Screw plug "E" for the manual filling of jacket with
water.
