1. INTRODUCTION
The convection oven in the PLANET range has been designed to work in areas where the
available space is limited.
The arrangement of the pans above each other in a uniformly ventilated area ensures the
space occupied is small and also the excellent cooking of the pastry and fine foods products.
The control panel has controls to:
1) set the desired temperature;
2) set the cooking time, at the end of which there is a sound warning;
3) to inject steam into the chamber.
Cooking takes place with a heated flow of air, sent through a series of holes in the sides by
each pan into the chamber. The even flow of air provides practically constant heat to ensure
even cooking over the whole of the product.
The ovens can be provided with chambers to take 5 or 8 pans of 60x40 cm.
They have been very carefully built using stainless steel both in the body and in the cooking
chamber to make for easy cleaning and long oven life even when cooking foods with high salt
or humidity content etc.
Dr. Zanolli s.r.l. thanks you for choosing our product. We can assure you that you have made
a good choice in putting your trust in a company that has decades of experience in the
making of high quality products, never cutting corners and always using the best materials.

in particular may easily and unpredictably cause a breakdown or damage the electrical
equipment and create a dangerous situation.
4.3 Electrical connection
Zanolli equipment is supplied with electrical connection cable with an earth wire.
In observance of the safety regulations currently in force it is compulsory to connect the
earth wire (yellow-green) to an equipotential system whose effectiveness must be
properly checked in accordance with the regulations in force.
Before carrying out any connections make sure the mains supply corresponds to
that to which the equipment has to be connected (see 3 and the plate).
See Fig. 5.3 for the exact cable output position for the equipment supply.
The supply cable must end with a plug to connect to an electrical supply board with a
corresponding socket and differential magnetothermal switch.
The plug-socket connection must be such that the earth wire is connected and first and
disconnected last and must be of the right size for the nominal current ( see 3.).Type CEE17
plugs and sockets are suitable, and any others satisfying the European norm EN 60309.
The thermal safety device must be calibrated for the total nominal current, the magnetic safety
device must be calibrated for the maximum instant current ( in the case of ovens it is little more
than the nominal current, while in the case of machines it is the surge current of the most
powerful motor), while the differential device must be set at the 30 mA current (see 3.).

5.7 Installation of units with exhaust type “A” with power lower
than 14 kW
To install units type “A”, it is necessary to comply with the following requirements for
room ventilation and exhaust of products of combustion.
The room where the appliance is to be installed must have at least two openings, made
directly in the wall and directly connected to the outside (one for suction of combustion air, and
the other for the exhaust of burnt gas). Cross-sectional area of each opening must never be
smaller than 100 sq.cm.
Air inlet must be placed as much as possible near the floor.
Exhaust of burnt gas must be placed in the top side of the wall.
If possible, the two openings must be placed in opposite position, they must never be
obstructed, and have to be protected by a grill with an useful crossing surface of 6 sq.cm. for
each kW used.
Rate between room volume and installed thermal capacity must be higher than 1,5
sq.m./kW.
5.8 Connection of steam outlet
The steam discharge outlet should be connected through the duct on the hood (see the
instructions). A pipe of Ø200 uld be connected to the outside.
Avoid long horizontal sections, where condensation could accumulate with
possible dripping.
Do not connect suction units as they would cause too much of a pressure drop
that would take heat out of the cooking chamber even with the valves closed.
See Fig. 5.3 for the exact connection position.
