1.4 Instructions for use
Appliance installation
▪The appliance must be installed by
qualified personnel only.
▪Each step must be carried out and
checked in full in the order specified.
Before using fully integrated appliances
for the first time, the cabinet front must
be mounted correctly as the metal parts
behind the cabinet front get hot during
operation.
▪Electrical connections must be carried
out by qualified personnel in accord-
ance with the guidelines and standards
for low-voltage installations and the spe-
cifications of the local electricity supply
companies.
▪A plug-in appliance may only be con-
nected to a socket outlet with earthing
contact, installed according to specifica-
tions. An all-pole mains isolating device
with 3mm contact opening should be
provided in the house wiring system.
Switches, plug and socket devices, cir-
cuit breakers and fusible cut-outs which
are accessible after installation and
which have all-poles switching are per-
missible as isolating devices. Effective
earthing and separately installed neutral
and earth conductors ensure safe and
fault-free operation. After installation,
live parts and cables with basic insula-
tion must not be accessible. Check old
installations.

3 Operating modes
3.1 Heating serving and tableware
Spread dishes across entire warming plate. The heating duration depends on the mater-
ial and thickness of the dishes as well as their quantity, height and arrangement. Stacked
plates take longer to heat up than individual items.
Do not place any large platters on their end in front of the ventilation slits. They block the
outlet openings for the heated air and as a result the dishes are not heated evenly.
▸ Put the dishes in the drawer.
▸ Touch the button.
–The recommended values illuminate.
▸ Close the drawer.
–The pilot lamp illuminates.
–The appliance heats up.
It takes approximately 45 minutes to heat place settings for 6 persons.
Unloading dishes
As heated dishes cools down quickly, take them out of the warming drawer just before
you need them.

4 Uses
4.2 Low temperature cooking
The setting is suitable for low temperature cooking and cooking to
completion of seared, small to medium-sized, high-quality cuts of meat (beef, lamb, pork,
veal) no thicker than 6cm. We recommend cooking larger pieces of meat in an oven or
combi-steam cooker.
Cooking meat at a low temperature for longer makes it tender and succulent.
Preparations
Sear meat before low temperature cooking.
▸ Use suitable glass, porcelain or ceramic cookware.
▸ Preheat the drawer containing the cookware at setting level .
▸ Rapidly heat a little fat in a pan.
▸ Sear the meat.
The searing times below refer to the sealing of meat in hot fat.

▸ Place the meat in the preheated cookware in the drawer to cook to completion.
▸ Cover the cookware with a lid.
Meat that has been low temperature cooked is not as hot as conventionally
cooked meat. Sauces should be served very hot. Put the plates in the warming
drawer during the last 45–60 minutes of cooking.
To keep meat that has been cooked at a low temperature warm, switch back to
level after low temperature cooking. Small pieces of meat can
be kept warm for up to 45minutes, large pieces for up to 2hours.
