Brief operating instructions
The combination of Rational Combi and Ultravent is
electrically interlocked. The Combi shall only operate
under the following conditions:
a) The UV must be electrically switched "ON”
b) All filters (charcoal filter and fat filter) must be
correctly installed, otherwise a "close door" error will
result. This is controlled by additional reed switches.
c) The filters must be relatively clean. This is con-
trolled by a differential pressure switch. In case the
filters are soiled the yellow warning light
(located
on the right side of the Ultravent) comes on and
the unit cuts out with close door error.
A) Operation:
Switching on the UltraVent® extractor hood:
Press main ON push button
• Extractor runs continuously at low fan speed when
the door of the oven is closed (reduced suction)
• On opening the oven’s door the UV power is au-
tomatically increased to full fan speed (maximum
extraction). During the first 50 seconds the door
can only be opened partially (door remains locked
by the locking system of the hood). After the 50
seconds have elapsed, it is possible to open the
door completely.
• When closing the oven’s door, automatically the
UltraVent® switches back to reduced suction (low
fan speed).
Safety instructions:
Caution:
Risk of burning!
• Parts may become hot.
• Always ensure that before any maintenance work
the electrical plug is disconnected and the grease
filter has cooled.
• Do not clean using high-pressure cleaning appli-
ances.
• Clean exterior surface with a mild soap and water
solution using a rag or similar.
• Ensure that the extractor vent is not clogged.
• Ensure when taking the hood out of function for a
longer period of time, or during cleaning, that it is
disconnected from power.
ATTENTION
Combi steamer will not work if:
- Ultravent is set to off or
- any of the filters are removed or
- filters are blocked with impurities or fat
("close door" displayed on combi steamer)
ATTENTION
if operation is reversed (low and full fan speed)
please review to installation instructions page 8
referencing connection of X23 to term 1 and 2 using
the White / Green wires only.
ATTENTION
Filters:
Carbon and fiber media filter are not cleanable.
Replace and dispose of properly.
