printed: 07/2023 Subject to change! RoFryUserManual.docx
4 Installation and putting into operation
In general all RoFry®units will be packed for safe transport after the final control in or-
der to reach you properly. Nevertheless we ask you to have a look at the machine on
arrival to detect any transport damages.
Note! Visible damages have to be reported immediately!
4.1 Unwrapping
•Open the box and remove the wrapping carefully.
•Take out all movable parts and make sure that they are complete.
•Remove all cartons and folio around RoFry®
•Pull the basket out of the unit with the black handle and remove all parts inside like operating
manual, legs, plugs etc.
4.2 Installation
•Install the legs and put the machine on the chosen place. Take care of the follow-
ing points:
•The RoFry® has to be placed on a horizontal level. Small unevenness can be cor-
rected by the adjustable legs.
•Make sure that all ventilation holes have at least 5 cm clear space.
•There has to be enough free space to load, unload, clean and maintain the unit.
•The machine has to be placed in a way that the complete area around it can be
cleaned easily.
4.3 Electrical connection
Note! While working on the unit with opened side-panels take care that the unit is dis-
connected from the mains. Even if the unit is switched off, the cooling fan may start to
run. Not paying attention may result in injury!
Please learn the electrical data of your unit from the nameplate. It is located at all types behind the
grease tray.
•Check whether your local electrical power supply is in accordance with the data on the name
plate.
•Make sure the supply cable is protected for units with a supply voltage as listed below:
240V (4/5-wire, min. cross-section 4) separately with 40 Amps,
240V (4/5-wire, min. cross-section 2,5) separately with 25 Amps
•Protection has to be done by use of a 3 pole line circuit breaker!
•The power supply needs to be manufactured from heat resistant, flexible cable. It is to be routed
to prevent any contact to hot parts.
•For further information please see the wiring diagram (below)
Note! After the unit is connected to the mains, check correct rotation direction of the
main fan: Remove the basket from the unit (pull the basket out of the unit with the
black handle, push the release and remove the basket). Switch the unit on and look
into the chamber. The fan wheel needs to rotate clockwise. If the rotation direction is
wrong, change two phases on the main terminal block (X1).
After finishing any installation work, maintenance or repair, check whether the ground
wires are connected properly to the casing and the side covers.

printed: 07/2023 Subject to change! RoFryUserManual.docx
4.4 Tap
Note! In general all Installation and Service work has to be done by an authorized
service technician! The following regulations have to be observed: DIN EN 1717 (alt
DIN 1988, Part4, technical regulations for drinking water installation/TRW.
•RoFry®requires a cold water connection; we recommend using a water-softening unit in case of
hard water above 6° dH (=Level 1).
•Use flexible pressure hose ½“ with ¾“ screw joint. A faucet as well as a flow-back-prevention has
to be provided on site.
•Water pressure should be between min. 100 kPa and max. 400 kPa. Use a pressure reducer in
case of water supply pressures above 400 kPa.
4.5 Sewage
Note! In general all Installation and Service work has to be done by an authorized ser-
vice technician! The following regulations have to be observed: DIN EN 1717 (alt DIN
1988, Part4, technical regulations for drinking water installation/TRW.
•The appliance needs an open sewage-connection, preferably ending in a funnel. UBERT recom-
mends a common flexible sewage-hose with ¾ “diameter to be fixed to the sewage connection
coming with the machine.
4.6 Cleaner & Rinsing Agent
Connect the cleaner and the rinsing agent canister with the RoFry using the tubes supplied with the
machine. Make sure that these tubes are routed away from any hot parts and that they do not kink!
4.7 Exhaust
For an average capacity utilization of 60 % (equals a continual preparation of 1000g frozen goods
of -18°C) there is an amount of exhaust of app. 130 m³/h that contains 6 kg water as hot steam. The
steam has to be disposed by an extraction system. The best solution for this is an adequate hood-
system. If this is not possible because of the rooming situation other solutions can be found. In this
case please contact our service members they will be glad to assist you.
4.8 Preparation of Using / Starting up
Before you can use the RoFry®you have to clean all removable parts carefully with a grease sol-
vent.
Note! Do not use flammable cleaners. Do not use high-pressure-, water pressure- or
steam jet- cleaning devices. You will have further information about this in the section
‘cleaning and up keeping’
After cleaning the RoFry®properly the smell will be minimal when using it the first time.

12 Operation

5 Operation
5.1 How RoFry®works
Once the device has been turned on, RoFry initializes. After pushing the STANDBY key is pushed,
RoFry enters the cold standby level. After confirming a program selection with the START key,
RoFry enters the hot standby level and is preheating to set temperature. This takes app. 2 minutes.
To fry food products, pull out the basket, put in the food to be prepared, push in the basket and push
the START key.
The basket starts to rotate and the main fan rotates full speed. The
air intake- and exhaust flaps are closed now. The temperature
drops. Now the computer control adjusts RoFry® automatically to
the amount and temperature of the food product by shortening or
lengthening the total cooking time to obtain a considerably even
product result.
The steam time phase starts. Now humidity is taken from the
product and turned into steam, cooking the product. During steam
time the temperatures in the chamber rise up to max. 20° C above
programmed operating temperature (if wanted). After the steam
time is finished, the flaps open again and the temperature will drop
to the start-level.
The roasting phase in which the goods get crispy begins. Now the
flaps are opened to let the vapor escape. Dry, preheated air is
blown via intake channel into the chamber. The flaps remain open
until the basket has been emptied.

6 Maintenance
Following some advises concerning maintenance, care, trouble shooting and service for RoFry®.
6.1 Cleaning and Care
6.1.1 Safety advices
•Do not use inflammable detergents cleaners. Never use high-pressure-, water
pressure- or steam jet- cleaning devices.
•Wear fire-safe, insulated gloves to prevent burnings when touching hot parts.
•Wear acid-proof gloves while cleaning the cold parts to prevent skin irritations.
6.1.2 General recommendations
•The unit has to be cleaned daily.
•Only use cleaners that are appropriate for food (neutral or alkaline detergents),
even if there are plain and persistent residues.
•After cleaning with special cleaners you have to wash all parts with clear water and
dry them afterwards so that there are no residues of the cleaner on these parts.
•It is absolutely necessary to watch out for some fundamental things to keep this
long-lived high-grade-steel-device working:
- always keep the high-grade-steel surface clean.
- watch out that there is always enough fresh air on the surface
- never contact the surface with rusty material
•Never use bleaching or chlorine cleaners.
6.1.3 Detergents
To make the cleaning fast and easy we have integrated some cleaners in our pro-
gram:
•RoFry®-Cleaner
•RoFry®-Rinsing agent (with descaling function)
•Stainless steel-cleaner:
You have to spray this from a distance of app. 25 cm on the surface and wipe it off
with a dry-cleaning rag. If you want to clean only small parts you have to spray it di-
rectly on the cleaning rag and wipe it off this way.
