Important (LEVEL A ONLY)
The water supply pipe must have an inside diameter of at
least 20 mm and be free of elbow unions.

The discharge steam condensation system can be fed with cold
water suitable for human consumption, having the following
characteristics:

- total hardness not exceeding 400ppm (40°fH); in LEVEL
A ovens equipped with CLEANING SYSTEM it is advisable to use
water of hardness not exceeding 5° French; for that purpose, a
water softener with automatic regeneration for installing on inlet
line “N” is supplied as an accessory by request.

- pressure between 22 to 36 psi (150-250 kPa); higher
pressures involve waste of water.

Note:

To check correct water installation, make sure the rotating wash
arm (CLEANING SYSTEM) does not turn below 100 rpm (120
max).

4.1.2 WATER INLET “B”.

(With feed pipe supplied)
The inlet for steam production must be fed with water suitable
for human consumption, having specific characteristics:

- total hardness between 5 - 50ppm (0.5 - 5 °fH) French
for reducing scaling inside the steam generator.
For that purpose, a water softener with automatic regeneration
for installing on inlet line “B” is supplied as an accessory by re­quest;
it has a kit for sterilizing the resins (by further request).

- pressure between 22 to 36 psi (150-250 kPa); higher
pressures involve waste of water.

- chlorine concentration (Cl -) not high (acceptable refer­ence value ~10 ppm), so as not to damage the steel structures
inside the oven.

- pH higher than 7.
For that purpose, a special filtering unit for installing on inlet line
“B” is supplied as an accessory by request. The purpose of this
unit is to reduce the water hardness to optimum values (below

50ppm "5 °fH") (optimum value), and therefore also serving as a

water softener.

(20°C).

4. WATER CONNECTION

(See the installation diagrams at the beginning of this handbook)

This equipment is to be installed to comply with the applicable
Federal, State, Local plumbing codes, or the Basic Plumbing
Code of the Building Officials and Code Administrators
International Inc. (BOCA) and Food Service Sanitation Manual
of the Food and Drug Administration (FDA).

The oven has two separate inlets (“B” and “N”) for the supply
water.
The supply pipes of both inlets must be equipped with a me­chanical filter and shutoff cock. Before installing the filters, it is
advisable to let a certain amount of water flow in order to clean
the pipe of any solid particles.

Important: The use of water treatment systems utilizing
methods different from those indicated by the manufacturer of
the equipment is not allowed and will completely invalidate the
warranty.

Likewise, dispensers of substances for preventing scale in
the pipes (e.g. polyphosphate dispensers) must not be
used because they can compromise correct machine
operation.

4.2 WATER DRAINING SYSTEM

The oven has an AIR-BREAK anti-backflow device inside to pre­vent possible backflow from the drainage system entering the
internal pipes and the oven compartment. This allows the drain
pipe to be connected directly to the mains system or discharging
into a floor grate.
The drain pipe (rigid or flexible type) can be run to the side or

16
