All WHIRLPOOL products are currently subjected to intensive product development, which
ensures that the products always contain the latest technology and the most up-to-date and
energy-saving methods of preparation.
Furthermore, the WHIRLPOOL products are entirely up-to-date with the latest developments/
technology in terms of
•ERGONOMICS AND SAFETY
•SIMPLE AND LOGICAL OPERATION
•USER FRIENDLY DESIGN
•RELIABILITY AND SERVICE
To ensure that our customers get an optimum and reliable product, all WHIRLPOOL units are

When communicating with WHIRLPOOL, we kindly ask you inform us of the serial number of
the oven that is stated on the approval plate. The approval plate is located on the right-hand
corner post of the oven cabinet, as shown below.

Installation and Connection
Unpacking the oven
The oven is best handled while still in its wrapping. Wherever possible, use a lifting trolley.
Introduce the lifting trolley under the lower cross tube of the stand and place a couple of
wooden blocks between the cross tube and the lifting trolley.
To achieve the best possible balance, introduce the lifting trolley from the front of the oven or
from the motor side. Note that the oven can be lifted off the stand.
Remove the original packaging from the oven. Do not remove the foil that covers the surfaces
until the oven has been installed, as once the foil has been removed the surfaces are
vulnerable to sharp objects such as tools.
Remove all packaging material that secures the racks in the oven chamber.
The packaging should be destroyed in accordance with national rules and
regulations governing waste disposal. Information on the composition of the
packaging material can be obtained from the WHIRLPOOL Customer Centre.

- 6 -
Installation and Connection
Installing the oven
To ensure that the oven functions correctly when installed, it should be placed upright and
level (horizontally). This is measured at the front and side edge of the roof, and adjustment is
made by means of the adjusting screws on the stand or on the legs of table models. The
height of the oven can also be adjusted to fit the trolley for rack.
Correct
Wrong
The oven should be placed 5 cm / 2 inch from the rear wall and the distance
between the right side of the oven and the nearest wall or piece of furniture, etc.
should be at least 7 cm / 2.75 inch. This is to ensure the necessary flow of cooling air
to the oven. Strong sources of heat such as hotplates, tilting frying pans, deep fat
fryers, etc. should not be placed near the oven, otherwise the warranty may cease to
apply.
(NSF) On an oven with stand, the distance to the floor must be at least 150
mm / 5.9 inch. Only 2½ threads must be visible on the adjustable feet.
(NSF) On table models, the legs must be adjusted to allow a minimum
clearance of 76 mm / 3 inch to the surface on which the oven stands.

- 7 -
Installation and Connection
Water connection
WHIRLPOOL ovens have one or two water connections.
To facilitate cleaning and service, the oven should be connected with an approved flexible ¾’’
hose and the permanent installations should be fitted with a stop tap.
Before connecting the oven to water, flush the tubes thoroughly.
Hardness of the water: max. 3 dH
Conductivity: min. 75 microsiemens
Water pressure: min. 2.5 bar (36 PSI) dynamic pressure (when CombiWash on),
max. 6 bar (87 PSI)
Water flow: min. 12 l/m
Water temperature: max. 20°C (68°F)
Chloride concentration: max. 100 mg/litre
Sulphate: max. 150 mg/litre
The connection wire to the system should be fitted with a stop valve and a nonreturn valve.
If the feeder is connected to the water distribution system with a flexible hose, this hose
should be VA approved.
If the water temperature exceeds 20°C / 68°F, problems with regard to
ClimaOptima calibration and cooling of the oven may occur.
Ovens with a steam generator must not be connected to a reversed osmosis
plant, as this may cause problems with the reading of the water level in the
steam generator.
The water connection must be carried out by an authorised plumber in
accordance with existing rules and regulations
Clogged up water filters and dirt in the solenoid valves are not covered by the
warranty.
To ensure that the water quality is in conformity with the above requirements,
the installation of a water filter in front of the water connection to the oven is
recommended.
The installation of a particle filter (0.25mm) is also recommended.
In the case of two water connections, the following applies:
1) 1 connection for raw water for the condensation jet (cold water). Located at the back.
2) 1 connection for the steam generator and the jet in the oven chamber. Must meet the
requirements applying to water supplied to household appliances; however, hot water with
a temperature not exceeding 20°C / 68°F can be used. Located at the front.

- 8 -
Installation and Connection
Drain connection
From the factory, the WHIRLPOOL ovens are equipped with a drain system that removes
surplus water from the oven chamber. This water may be condensed water from the products,
or it may occur when the oven chamber is cooled down with cold water, or when the oven
chamber is cleaned.
Connection must be carried out by an authorised plumber, to an open or to a closed
drain.
It is recommended that a water outlet is available/established in the floor of
the room where the oven is located.
The drain must never end directly beneath the oven.
The drain must be of stainless steel or an equally temperature-resistant material, have a
diameter of at least 50 mm / 2 inch and a fall of at least 3° or 5%.

- 9 -
Installation and Connection
Electrical connection/survey of supply lines
The electrical connection must be carried out by an authorised electrician in accordance with
existing rules and regulations.
The wiring diagram is located in the motor compartment.
The terminal for the electrical connection is located behind the right side plate.
An approved plug outlet or a safety cutout must be located close to the oven so that
the oven can be disconnected during installation and repair. The safety cutout must be
able to cut off all poles with a total distance of break of at least 3 mm. Each of the two
units in a stacked arrangement (CombiPlus) must have its own plug outlet or safety cut-
out.
The warranty does not cover incorrect connection.

Exhaust
The WHIRLPOOL ovens are equipped with an open/direct exhaust system that removes
surplus humidity from the oven chamber. The exhaust system has an electrically operated
damper.
The exhaust tube can be connected to a ventilating system. In that case, a special
extraction funnel is fitted to avoid suction directly from the oven chamber. This extraction
funnel can be ordered from WHIRLPOOL.
The scope of supply also includes a specially designed extraction hood, see illus. below.
If an extraction hood is installed in the ceiling above the oven, it should project 50 cm over
the front of the oven. The suction effect should be 400 – 800 m3/h.
The ventilation motor can be controlled directly from the oven. This means that the
ventilation starts when a program is started and runs for 10 minutes after the program is
completed.
The installation of the ventilation must comply with local rules and
regulations.
