3.1 INSTALLING THE POWER SUPPLY CABLE

To access the power supply cable connection terminal board,
proceed as follows:
Model 6 - 10 - 20 GN
• Remove the left side panel.
• Connect the power supply cable to the terminal board accord-
ing to the instructions given in the wiring diagram and fasten the
power supply cable by means of strain-relief fi tting (not furnished
with the oven).
Failure to comply with safety rules and regulations relieves
the manufacturer of all liability.
The manufacturer requires when stacking units each appliance
have its own branch circuit protection. An oven unit stacked with
an blast chiller unit should have a separate protection for the
upper and lower units.

4. WATER MAINS CONNECTION

(Refer to the installation diagrams at the beginning of this booklet).
This equipment is to be installed to comply with the applicable
Federal, State, Local plumbing codes, or the Basic Plumbing
Code of the Building Offi cials and Code Administrators
International Inc. (BOCA) and Food Service Sanitation Manual
of the Food and Drug Administration (FDA).
When connecting the appliance to the water system with
fl exible tubes they must be new and not used.
The appliance is fi tted with two separate water inlets ("B" and "N").
The water lines supplying both inlets must be fi tted with a
mechanical fi lter and shut-off valve (keeping with local plumbing
codes).
Before fi tting the fi lters allow the water to fl ow out for suffi cient
time to fl ush any solid particles from the piping.
Pressure between 22 and 65 psi (150-450 kPa).
WATER INLET "N"
Attention (water inlet N)
If the supply pipes provided with the appliance are not long
enough for installation, use longer ones with int. diameter at
least 3/4" (20 mm) and free of elbow unions.
Note:
To check correct water installation, make sure the rotating wash
arm (CLEANING SYSTEM) does not turn below 100 rpm (120
max).

4.1 WATER SUPPLY CHARACTERISTICS

The appliance must be supplied with drinking water having
specifi c characteristics given in this section.
HARDNESS FILTER
RATING
The hardness values given in the table are for reducing scaling
inside the steam generator and possible cooking compartment
washing system.
If the available water does not have these hardness characteristics
a water softener must be installed.
Therefore the Automatic Water Softener with automatic
regeneration for installing on the inlet line, can be requested as
an accessory; it has a Resin Sterilizer kit (also by request).
HARDNESS AND CHLORIDE FILTERS
The chloride concentration (Cl-) (ppm - mg/l) values with pH
(>7) and Conductivity (µS/cm) (measured at 68°F)(20°C) must
be such as to not damage the steel structures inside the oven
(only water inlet B).
Therefore the characteristics of the available water must be
identifi ed in the graph given at the end of this handbook (page
107), if necessary installing at the inlet the type of fi lter indicated
in the relevant area of the values.
The fi lters indicated are:
- No fi lter for chloride (Cl-) in the conforming area (Normal)
- Nanofi lter
as an accessory on request, called Water Filter.
- Osmotizer.
Make sure the water coming out the fi lter is inside the optimum
area (Normal).
These fi lters also have the function of reducing the water hardness
to optimum values (below 50ppm)(5°fH), and therefore also act
as a water softener.
ATTENTION: Periodical checking according to the filter
manufacturer's instructions is important to maintain its effi ciency
and avoid the risk of corrosion in the appliance.
Level C ovens are convection ovens. If water having characteristics
outside those specifi ed is used to create humidity inside the
oven, there will be the risk corrosion of the compartment and
that present inside it.
Carry out regular maintenance of the water softeners and fi lters
to ensure their optimum effi ciency.
To avoid damage to the appliance, after every periodical
regeneration do a fi lter cleaning cycle without introducing water
in the oven.
The manufacturer declines any liability in case of incorrect
maintenance.
Important:
The use of dosing systems designed to prevent the build-up
of lime-scale in pipes (i.e. polyphosphate dosing systems) is
prohibited since such systems may impair the performance
of the appliance.

4.2 WATER DRAIN SYSTEM

The oven is supplied with an air-break system to prevent any
backfl ow from the drainage system from reaching the oven's
internal circuits and the cooking chamber. The presence of this
system means that the drain pipe can be connected directly to
the mains drainage system or routed to a fl oor gulley with grating.
The fl exible drainage hose or rigid pipe can be directed to the
side or rear of the appliance if the oven is not positioned against
a wall; this line must not be directed towards the front of the ap-
pliance to prevent interference with roll-in grid racks. The drainage
pipe internal diameter must be no smaller than the oven drain
outlet (1 1/4"), no longer than 3 feet (1 metre) and must resist
temperatures of up to at least 212°F (100°C). Avoid restrictions in
the case of fl exible hose pipes, do not fi t elbows on metal pipes
anywhere along the drainage line. Also avoid horizontal sections
