Take care!
Observe the weight of the units. Use carrying
aid to avoid injuries. Wear appropriate ppe's
Type 112: (Vitro + cabinet) 168 kg

Type 211: (Vitro) 195 kg
Type 211+: (Vitro) 223 kg
Type 311: (Vitro) 251 kg
Type 311+: (Vitro) 279 kg
Attention:
In order to avoid damages observe procedure shown
on pictures A to E.
For 112 models it is forbidden to lift the unit at the
bottom of the cabinet. Pict. A
For 211 and 311 models it is forbidden to lift the
unit at the axle of the pan or of the lid. Pict. A
Procedure:
• Lift up unit at one side using carrying aids as
shown on Pict. B
• Pull the unit off to the side Pict. C
• Lift up unit at the side which is still standing on
the pallet and pull out pallet. Pict. C
• Lower the unit. Pict. D
• For transporting the units without pallets use the
pallet jack as shown on Pict. E
Attention:
To move 211 - 311 models without palette the fol-
lowing must be observed. Use two wood bars with
a minimum length of the unit and put them on the
pallett jack.
Run pallet jack in lengthways underneath the unit.
Thus the weight of the unit is evenly allocated to
the cross bars.
Observe center of gravity - danger of tilt-
ing!
Handling: Take the unit off the pallet

Acessing the unit:
Step 1
This step is valid for all kind of units Pict.1
(1) Pull off central dial
(2) Loosen screw (3 mm hex socket)
(3) Now you can remove the control panel.
The control panel is connected with a cable
mass. to the electric board. Take care not to dam-
age it.
Step 2 (211 & 311 models)
To access the whole electric board you must now
remove the front panel and the side panel. To do so:
Pict. 2
(1) Loosen both screws under the front panel (3 mm
hex socket)
(2) Lift front panel without removing it completely!
(3) Slide side panel to the front
(4) Remove side panel by lifting it
Step 2 (112 models)
(1) Once the control panel removed and standing
either on the left pan or left lid
(2) Loosen both screws under the front panel (3mm
hex socket) Pict. 3
Attention
When reassembling the control panel, make sure
to apply enough pressure on the left side corner in
order to ensure the latch engages. Thus facilitating
a sufficient sealing of the technical compartment.

We built our units by level. That means
the pan is in accordance with the frame. Once you
have levelled the frame, the pan should be levelled
also.
The levelling is done exclusively by adjusting the
foots of the unit. Proceed as follows:
Step 1
Units are delivered with the foots fully screwed.
Before starting to level the unit unscrew each foot
of two turns. Pict. 1
Step 2
Open side panel and level unity by adjusting both
foots. Pict. 2
Step 3
3. Open the lid and check pan level from the right to
the left. Adjust if necessary by turning the left front
foot. Pict. 3
Step 4
Check pan level from the front to the rear.
Adjust the left back foot if necessary. Pict. 4

Step 5
Check the pan is laying on both stop collars, thus
are factory adjusted.
If it is necessary to adjust the stops of the pan take
care of following: Pict. 5
> The base frame must be fully levelled. It is useless
adjusting the pans stops as long as the base frame
isn't properly levelled.
> That the lid doesn't collide with the pan when
closing.
Step 6
Move the lid full downward and check for lid to pan
lining up. If necessary adjust using the left rear foot.
Pict. 6
For 211 & 311 pressure models, ensure that when
the lid is lying on the pan there is not too much
play in between. This could lead to damage the unit
while locking the lid for a pressure cooking mode.
Step 7
Characteristic of the models 211 et 311 with
pressure option
Ensure the distance between the four locking hooks
and the edge of the pan is even.
This is a very important check! Pict. 7
We highly recommend to fix pressure units on the
floor using our special fixing accessory. (Refer to
"option floor fixing" in the chapter options.

Check now the setting on the opposite pan.
Step 3
Put your level on the right or left pan as you like.
Now you can level the unit from the front to the rear.
To do so adjust the rear feet of the unit.

Requirement
You need to ensure, depending on the
national and local regulations, that each of our
devices are separately connected through a
30mA RCD circuit breaker.This device must
be located in the electrical distribution box.
Regulation
• Follow the installation instructions
and the information on the name-
plate when connecting the unit
(See plate description on next page).
• Equipment must be connected to an electrical
supply line with standards in your country.
• Observe your local electricity supplier regula-
tions.
• On-site installation: provide accessible all-pole
disconnection device with a minimum of a 3
mm contact gap.
• Applicable standards: EN 60335, IEC 60335
Power supply cable:
• Electrical connection data see page 17
• For appliance connections, precise dimensions
and connection points, see pages 15 - 18 or
data sheets page 28 - 30.
• Units can be connected directly or through a
suitable connector.
• Before connecting or disconnecting the mains
be sure the unit is switched off.
• Use at least a cable quality like HO7RN-F
if flexible, V1000R02V if rigid. Take
care to tighten enough the cable gland.
(Stress relief)
• The cross-section of the power cables must be
based on the current consumption and on local
regulations.
Electric wiring diagrams
• The wiring diagram can be found inside
a plastic bag in the technical compart-
ment, after removing the side panel. See
chapter: installation, accessing the units.
Please put it again there after using it.

Concerning the cross section of the cables
Current consumption, recommended fuses and
cross-sections are depending also on:
• Local prescriptions
• Cable length & quality
• Quality of the power supply network.
Thus they are to be adapted to local conditions.
Values shown are for a maximum cable length of 2
m. It is the responsibility of the person installing the
unit to adjust these values according to the length
of cable which will be in use.
Concerning the supply voltage
The maximum allowable tolerance of the supply volt-
age (supply voltage see name plate) is in the range
of -10% up to +10%.

Common information
Our units comply with NF EN 1717: 2001-05 regula-
tions, which are recognised by the SVGW and DVGW.
A soft water connection is not necessary. If regard-
less the unit shall be connected to soft water make
sure that the remaining water hardness is set to 5°e
(7°fH or 4°dH) minimum
The appliance must be connected to the facility
water supply with a supply hose that conforms to
EN 61770 resp. IEC 61770 or of similar quality.
The water supply hose must fulfil the local or stand-
ard hygiene requirements for hoses in drinking water
systems.
We recommend to install an individual shut-off valve
for each appliance
We do not talk here about local specific laws.
Installers are responsible to take account of local
regulations.
Connection
(1) Cold water supply (3/4“)
Quenching or Pan filling
(2) Hot water supply* (3/4“)
Pan filling only. Max 60°C
Models 112 Pict. 1
Models 211/311 Pict. 2
Pressure & flow
Water pressure has to be in the range between
150 kPa and 600 kPa. Recommended is 300 kPa
minimum.
Nominal flow should be between: 1,8 to 2,5 m3/h
Temperature
For units without hot water connection, maximum
temperature of cold water connection should not
exceed (30°C- 86°F) max.
For units fitted with hot water connection, the tem-
perature should not exeed 60°C or 140°F. Take care
of the connection!
*Hot water connection is an option, devices are not
fitted as standard.
