Operating Modes - Thermador HPIB42HS Use And Care Manual

OPERATING MODES

EXHAUST-AIR MODE:
K The hood fan extracts the kitchen vapors
and conveys them through the grease
filter into the atmosphere.
K The grease filter absorbs the solid
particles in the kitchen vapors.
K The kitchen is kept almost free of grease
and odors.
D When the hood is operated in
exhaust-air mode simultaneously with a
different burner which also makes use of
the same chimney (such as gas, oil or
coal-fired heaters, continuous-flow heaters,
hot-water boilers) care must be taken to
ensure that there is an adequate supply
of fresh air which will be needed by the
burner for combustion.
Safe operation is possible provided that the
under pressure in the room where the
burner is installed does not exceed 4 Pa
(0.04 mbar).
This can be achieved if combustion air can
flow through non-lockable openings, e.g. in
doors, windows and via the air-intake/
exhaust-air wall box or by other technical
measures, such as reciprocal interlocking,
etc.
CAUTION
Avoid carbon monoxide poisoning –
Provide adequate air intake so
combustion gases are not drawn back
into the room.
An air-intake/exhaust-air wall box by itself is
no guarantee that the limiting value will not
be exceeded.
Note: When assessing the overall require-
ment, the combined ventilation system for
the entire household must be taken into
consideration. This rule does not apply to
the use of cooking appliances, such as
cooktops and ovens.
CIRCULATING-AIR MODE:
K An activated carbon filter must be fitted
for this operating mode (see Filters and
maintenance).
The complete installation set and
replacement filters can be obtained from
specialist outlets.
K The extractor-hood fan extracts the
kitchen vapours which are purified in the
grease filter and activated carbon filter
and then conveyed back into the
kitchen.
K The activated carbon filter binds the
odorous substances.
If no activated carbon filter is installed, it
is not possible to bind the odorous
substances in the cooking vapours.
Gas Cooktops / Gas Ranges:
CAUTION
Avoid risk of burns or damage to extractor
hood.
Do not use all gas burners simultaneously
at high settings for a prolonged period
(max.15 minutes).
If the hood is located over a gas cooktop,
operate the hood at maximum setting
whenever three or more gas burners are
being used.
