4. INSTALLATION WARNINGS
WARNING: These installation instructions are intended
only for staff which is qualified for the installation and the
maintenance of electrical and/or gas plant.
Installation by any other person may cause damage to the
equipment, persons, animals or things.
Furthermore, if it is necessary to make any modifications or
additions to the electrical and/or gas plant, where the equipment is
going to be installed, the person carrying out such alterations must
obtain certification that the works have been carried out in
accordance with the norms in force in that country.
4.1. Delivery checks
Unless otherwise agreed the products are carefully packed in a
strong wooden crate with a blister sheet of nylon to protect them
from shocks and humidity during forwarding and are delivered to the
driver in perfect conditions.
We recommend, however, that packaging is checked on arrival of
the goods, to ensure that there are no visible signs of damage. If
there are any such signs, indicate their nature on the delivery note,
which has to be signed by the driver.
Once the equipment is unpacked, check to see if it has suffered any
damage. Also check that any parts which are delivered unattached
to the equipment are present. If there has been any damage to the
equipment and/or any parts are missing, do not forget that the
forwarding company will accept complaints only up to 15 days from
the delivery day and that dr. Zanolli S.r.l. will not be liable for
damage suffered to its products during transport. We are
nevertheless willing to help you in presenting your complaint.

10
If there is any damage do not attempt to use the equipment
and call upon professionally qualified staff.
4.2. Choice of place of installation
The good, safe and long working of the equipment also depends on
the place where it is installed, so it is advisable to carefully evaluate
this before it is delivered. Install the equipment in a dry place which
is easily accessible both as regards its use and its cleaning and
maintenance. The area around the equipment must be free of
encumbrances. In particular it is necessary to avoid obstructions to
the cooling apertures. (Figure 15)
The equipment must in any case be installed at least 20 cm from
the walls of the room and from other equipment.
Finally, it is necessary to ensure that the temperature and
relative humidity of the place in which the equipment is installed
must never exceed the maximum and minimum values indicated in
the characteristics section (see 3.). In particular, if the maximum
temperature and relative humidity are exceeded, the equipment
may easily and unpredictably go out of order or be damaged in its
electrical parts, thus creating a dangerous situation.
4.3. Electrical connection
Zanolli equipment are supplied with a cable for the electrical
connection with earth lead. In observance of the current safety
norms it is compulsory to connect the earth wire (yellow-
green) to an equipotential system, whose efficiency must
be properly checked against the norms currently in force.
Before making any connections ensure that the characteristics
of the mains supply to which the equipment has to be
connected correspond to the feed characteristics required by
the equipment itself (see 3 and plate on equipment).

11
See (1) figure 5-3 for the exact position of the feed cable
output.
The feel cable must end in a plug, which connects to an electrical
feed panel with a corresponding socket and a differential magneto-
thermal switch.
The plug-socket connection must be such that the earth is
connected first and disconnected last and must be of the correct
size for nominal current (see 3).
Suitable plugs and sockets are the industrial type CEE 17 of any
which satisfy the European Norm EN 60309.
The terminal safety device must be set for total nominal current, the
magnetic safety device must be set for the instantaneous maximum
current (in the case of ovens it is a little above the nominal figure, in
the case of machines it is the pick up current for the most powerful
motor), while the different device must be set to the 30 mA current
(see3).
dr. Zanolli S.r.l. shall not be liable for any damage which results
from failure to observe the above mentioned norms.

5. INSTALLATION
5.1. Check list
There are no separately supplied parts.
5.2. Choice of the place of installation of the oven
Avoid obstructions to the cooling openings located on the right side
of the module (Figure
5.1).

to be completed with the addition of other modules or accessories
from the series (hood, proofer and so on).
5.3. Moving the module
When unloading and moving the
module when it is packed, use a fork-
lift or transpallet which has a capacity
at least equal to the weight of the
module, and insert the forks into the
space provided in the lower part of the
packing.

When moving a module which is not packed, insert the forks in the
upper chamber.
It is also possible to transport the module by means of the two
hooks which are accessible from the openings in the top part.
In any case, to avoid unforeseen movements, take note of the
position of the centre of gravity (Figure 5.2 and table 5.1).
Table 5.1 - Centres of gravity
In addition, to avoid damage to the module, insert some
protective material between the forks and the module itself.
5.4. Mounting the module
Put the modules one above the other one in the right order (proofer
or base, baking module, hood) and fix by means of the supplied
hooks and screws.
5.5. Connecting the steam outlet
The steam outlet should be connected through the duct on the hood
(see instructions).
Avoid long horizontal stretches, as they may cause
accumulation of condensation and possible dripping.

7. FUNCTIONS
7.1. SYSTEM FUNCTIONAL STATES
7.1.1. Standby on/off button
When on standby the panel is powered but no system function is
enabled. The general remote switch is disabled and the message OFF
is displayed on the set display on the control panel along with the
current time on the display with flashing seconds dot (between
the second and third figure, ½ second on, ½ second off).
All buttons on the panel are disabled except for the button (system
on) and the key, pressure on which will bring the system to clock
setting mode (see “programming” section).
Pressing the button, the system comes on, the last SET temperature
programmed is displayed on the set display , and the cycle used
prior to switching the oven off is displayed on the display.
7.2. SETTINGS
7.2.1. Set temperature setting
To set the SET temperature use the and buttons until the desired
baking temperature appears on the display.
7.2.2. Upper and lower element setting
Pressing the buttons varies the time the oven heating elements
remain on. Each time the button is pressed increases this value by 1
unit, up to a maximum of 9 units. Further pressure returns the value to
0.
NB. Each unit on the two displays corresponds to 5 seconds element on
time. For the remaining units the elements remain off. The total duration
of the cycle is 45 seconds.

18
The on time of the two elements can be varied at any time, even during
the baking cycle. The upper elements during the first part of the cycle
while the lower ones come on during the second.
For example, setting the upper elements to 6 and the lower ones to 5
gives the following result:
5 10 15 20 25 30 35 40 45
Upper ON OFF
Lower OFF ON
Note that with this setting, for the first 20 seconds only the upper
elements are on, so the oven uses half the total power. Over the next
10 seconds both the upper and power elements are on, with the oven
using full power. In the remaining 15 seconds, on the lower elements
are on, so the oven once again uses half its available power.
7.2.3. Economy button
Pressing the economy button sets power values to pre-set levels
(upper 5 and lower 3) with the following result:
5 10 15 20 25 30 35 40 45
Upper ON OFF
Lower OFF ON
Note that with this setting, in the first 25 seconds only the upper
elements are on, with the oven using half power. Both elements are off
for the following 5 seconds. In the remaining 15 seconds only the lower
elements are on and so the oven once again uses only half power. This
means that throughout the cycle the oven never uses more than half
power and for 5 seconds power consumption is zero.
A similar result can be obtained through manual power settings, if the
sum of upper and lower times is less than or at most equal to 9.
7.2.4. Start/Stop button
Pressing the start/stop button starts the baking cycle according to the
previous setting.

19
7.2.5. Oven light button
Pressing the oven light button switches on the light in the oven.
Press again to switch it off.
7.2.6 Light switch for suction hood - Light switch for steam
generator
The light switch for suction hood control
is placed on the side part of the control
panel, on the upper side (Pos.1 of Fig. 7.1).
Push this switch on position 1 to start the
suction hood. Push this switch on position 0
to stop it.
Always on the side part of the control panel,
but at the bottom, you find the light switch
that starts and stops the steam generator,
if the oven is equipped with this accessory (see Pos.2 –Fig. 7.1).
7.3. PROGRAMMING
7.3.1. Clock and day setting
The time and day can only be set with the system on standby, that is to
say when the display “OFF”.
Pressing the key and holding it for 3 seconds displays the time on the
display with the two figures corresponding to the hour flashing.
The correct hour can be set using the and keys. To memorise the
new hour setting and pass on to setting minutes, press the key again.
The minutes start flashing and can be set in the same way as the hours.
Before pressing again, set the day of the week using the upper
element power sequence button . This displays the number
corresponding to the day on the upper element control display .
