14 Initial Installation Procedure
printed: 03/2012 Subject to change! < RTUserManual.doc
4 Initial Installation Procedure
Our Infrared Rotisseries are packed for safe transport, so that they can reach their
destination without any damages. However we advise an examination of Infrared
Rotisseries right after delivery.
Attention! Do report visible damages immediately!
4.1 Unpacking
• Open the box and take out the wrapping and filling material carefully.
• Take out all single parts and check whether these are complete (compare with enclosed dis-
patch documents).
• Now please remove the cardboard packaging and all wrapping and covering folios from the rotisserie.
4.2 Installation
Install the unit and set it up at the desired place. Make sure that the unit is visible to
your customers to create a demand for your food offer and increase your sales.
During installation please note the following:
• Install the feet of the unit and set it up at the place as wanted.
• Set up the unit on an even, horizontal surface! Line up the unit horizontal.
• Observe that all slots for air supply and ventilation are held free and are at least
100 mm away from walls or similar things which could block the slots.
• Take care that the area around the rotisserie is free in order to load, unload, clean
the unit or that maintenance works can be done smoothly.
•
The unit has to be set up in a way that the surrounding area can be cleaned.
4.2.1 Place of operation
Important! The rotisserie has to be set up on a
n even, stable and fireproof surface in
a good ventilated room and below an existing ventilation hood. Depending on the
model the unit can be placed free in a room or at a temperature-
resistant wall or in
one line with other equipment. A minimum distance o
f 200 mm from walls made of
inflam
mable material has to be observed. If these distances fall below corresponding
heat pro
tection measures have to be made, for instance tiling of walls or application of
a radiation protection. Before you install the unit ch
eck the type plate, whether the unit
is ap
proved for the the local existing kind of gas. If the kind of gas indicated on the
type plate does not agree with the required kind of gas, the installation of the rotisserie is not allowed until the unit has been adjusted according to the requirements.
Note! When installed in a sales vehicle, make sure that the provided converter creates a sinusoidal rotating field.
Note! It is not allowed to set up a workplace in the area of radiation heating as it is
too hot there.
Initial Installation Procedure 15
printed: 03/2012 Subject to change! < RTUserManual.doc
4.3 Installation
Before the unit can be installed it is necessary to have the comments / approvement
of the responsible gas supply company.
Only a installation company which is approved by the responsible gas supply compa-
ny is allowed to set up the unit, install the gas connection and to start the operation.
The laws, technical regulations and directions mentioned under section 4.2.3 have to
be observed. Only approved c
ompanies are allowed to do maintenance work or gas
adjustments and they have to observe this manual and corresponding regulations.
4.3.1 Statutory orders, technical regulations and directives
The following regulations have to be observed when the unit is set up:
• local statutory orders
• local laws valid for your countries
• technical regulations for f luid gas
• directions of the local gas supply company
Furthermore regulations of accident prevention valid for your country have to be observed.
For operating the uni
t outside Germany the national laws, technical regulations and
directions of the specific country are valid.
4.3.2 Gas connection
Check whether the gas unit is adjusted for the existing kind of gas. Compare the indicated kind of gas on the type plate with the
existing kind of gas. If this is not the case
an adjustment according to the local requirements is necessary. The gas connection
depends on the rotisserie model (external thread right acc. to DIN-
ISO 7/1 [DIN 2999,
part 1] 1 inch). The connection with the gas supply has to be made through the inter-
mediary of a connection armature and through a thermically secured shutoff device.
Technical regulations have to be observed. Only an approved technician is allowed to
do this work. After the gas connection has b
een made all points of connection have to
be tested for leaks under operation pressure by leak detecting spray or by brushing
with foam forming mediums which do not cause corrosion.
4.3.3 Electrical connection
Note! Note that also after installation and electrical connection the plug must be ac-
cessible. If this is not possible due to structural reasons, or if the unit is connected
permanently, the power supply needs to have an interlock switch.
Note! During any servicing, take care that the unit is disconnected from the mains!
Not paying attention may result in injury!
Please learn the electrical and technical data of your unit from the nameplate.
· The unit is ready f or plug-in.
· For power supply a shockproof socket is necessary.
· Make sure the supply cable is protected separatly with 16 Amps.
The existing connection cable for the electrical connection is positioned at the lower

right rear wall.
Note!
After finishing any installationwork, maintainance or repair, check whether the
ground wires are connected properly to the casing.
4.4 Preparation for operation
Before you can operate the Infrared Rotisserie you have to clean the unit and all removable parts
(eg. spits etc.) carefully with a grease solvent detergent. Afterwards you have to dry all surfaces.
Note! Do not use flammable cleaners. Do not use high pressure-, water pressure- or
steam jet- cleaning machines. You will have further information about this in the section”cleaning and maintenance”.
After cleaning the Infrared Rotisserie properly the smell will be minimal when using it the first time.
4.4.1 Betriebsbereitstellung
The units have to be checked on their designed nominal heat load and adjusted accordingly if required when they are installed the first time or after any maintenance work. Please learn the necessary data from the corresponding table.
4.4.2 Control of nominal heat load
Firstly, please check whether the unit is adjusted for the existing kind of gas. For this you have to
check whether the indication on the type plate corresponds to the existing kind of gas. If you adjust
the unit for other gas types please check the indication of the nozzles. The nominal heat load results from using the right nozzle with connection pressure of
+ 20 mbar with natural gas H and natural gas L (for France E+)
+ 50 mbar with fluid gas
by taking effect of the corresponding tuyère area.
The permission of operation with the resulting nominal heat load under dependency of the planned
nozzles results from the following connection pressure bounds:
15 to 25 mbar with natural gases)
25 to 35 mbar and 42.5 to 57.5 mbar with fluid gas
Starting the operation outside these pressure bounds is not permitted.
