Installation

Unpacking the Oven

The oven is best handled while in its wrapping. Use a lifting trolley whenever possible. 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 the surfaces are
vulnerable to sharp objects such as tools, once the foil has been removed. Remove all protecting parts
that secure the racks in the oven compartment.

The packing must be destroyed in accordance with the rules and regulations

covering the disposal of rubbish in your country. Information on the packaging

material can be obtained from our technical department.

Combi-Oven Installation

Positioning of oven

To ensure that the oven functions correctly when installed, it should be placed upright and level
(horizontally). This is measured at the front edge 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.

The oven should be placed at least 2 inches from the rear wall and the distance between the sides of the
oven and the nearest wall or piece of furniture, etc. should be at least 4 inches. This is to ensure the
necessary flow of cooling air to the oven. Strong sources of heat such as frying pans, fryers, etc. should
not be placed near the oven, especially not on its right side; otherwise the warranty may cease to apply.

Water Connection

As standard, the BKI Combi has one water connection. To facilitate cleaning and service, the oven should
be connected with an approved flexible 1/2"
stop-tap for the water supply to the oven.

Before connecting the oven to water, flush the water tubes thoroughly. Then fit the dirt filter and connect
the oven.

Water Requirements

Hardness: max. 3 dH
Conductivity: min. 75 microsiemens
Water pressure min. 1.5 bar (150 kP), max.6.0 bar (600 kP).
Water pressure Combi Clean: min. 2.5 bar dynamic pressure (CombiClean activated)
Water temperature: max. 20°C
Chloride concentration: max. 100 mg/litre

If the feeder is connected to the water distribution system with a flexible hose, this hose should be VA
approved.

A reversed osmosis plant must not be connected to ovens with a steam

generator as this may cause problems with respect to the registration of the

water level in the steam generator.

hose and the permanent installations should be fitted with a

5

Combi-Oven Installation

An authorized plumber in accordance with existing rules and regulations MUST

carry out the water connection.

Clogged up water filters and dirt in solenoid valves are not covered by the

warranty.

Alternatively, the oven can be supplied with two water connections (optional equipment):

1. for raw water for condensation nozzle (cold water)

2. for nozzle in oven cabinet and steam generator. Must meet the requirements made on water for
drain connection, however, the water temperature must not exceed 140°F.

Exhaust

The BKI Combis are equipped with an open/direct exhaust system that removes surplus humidity from
the oven compartment. The exhaust system has electrically or manually operated air exhaust.

The vent pipe can be connected to a ventilating system. In this case, a special extraction funnel is fitted to
avoid suction directly from the oven compartment. This extraction funnel can be ordered from BKI.

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 - 800m

The ventilation motor can be controlled directly from the oven. This means that the ventilation starts when
a program is started and runs for 5 minutes after the program is finished.

/h.

Electrical Connection

An authorized electrician in accordance with existing rules and regulations must carry out the electrical
connection.

There is a wiring diagram in the motor room.
Locate an approved plug outlet or a contact breaker close to the oven so that the oven can be

disconnected during repair and installation. The breaker must be able to cut off all poles with a length of
break of at least 3 mm. To facilitate cleaning and service, use an approved flexible connection cable, type
H05RN-F.

The oven may leak 1 mA current per kW.

After connection, check that the fan rotates in the right direction, i.e. COUNTER­CLOCKWISE.

If the fan rotates in the wrong direction, the oven does not operate correctly, which may cause damage to
the oven.

Drain Connection

As standard, The BKI Combi is equipped with a drain system that removes surplus water from the oven
compartment. Water may occur when steam is used in the oven and when the oven is cleaned.

An authorized plumber must carry out connection. The oven must be connected
to an open drain and the connection must end at least 20 mm above the outlet
grating or funnel.

The drain must never end directly under the oven. The drain tube must be of stainless steel, have a
diameter of at least 38 mm and a fall of at least 3° or 5%.

Never connect directly to a water trap so as to avoid obnoxious smells, bacteria
and possibly low pressure, suction or overflow.

Adjusting Flaps

The flaps can be adjusted individually to achieve a uniform baking result. Experience shows that the
following basic setting produces the best result in the vast majority of cases Air gap setting in mm:

Type 1.06 and 1.10

Type 2.10

For types 2.10 we recommend that a 10 mm rail be fitted at the top (part no. O 11.588).

Combi-Oven Maintenance

Cleaning

The construction of the BKI Combi makes it very easy to clean. The oven compartment is all-welded in
stainless steel and accordingly splash proof. You will find the easy-to-use hand shower with flexible hose
very suitable for inferior cleaning.

The door gasket at the oven door can easily be removed which ensures a quick and efficient clea ning
around it

The flat front panel also makes the exterior cleaning quick and efficient.

1. Interior cleaning
Manual Method

a. Always clean the oven when it is cold or cool the oven compartment down to below 140°F.
b. Add mild or strong oven det ergent (according to requirement) with a soft brush to the sides of

the oven compartment, rack etc. Protect your face and hands as the oven detergent may be

caustic.
c. Leave the oven detergent for approx. 5-10 min.
d. With the MULTI STEAMING mode, the oven is set to steam for approximately 10 min. at

194°F.
e. Flush the oven compartment with the hand shower.
f. Check that the water can pass freely through the drain. The grating that comes with the oven is

to be placed over the drain hole inside the oven.

Integrated Cleaning Program (CVC and S Controllers only)

a. Choose the cleaning program (“198” for CVC controller and “C” for S controller). The display

says “CLEA”.
b. Press “START”.
c. Apply an oven detergent with a soft brush or a sprayer when the alarm sounds and the display

says ”SOAP”.
d. Close the oven door.
e. When the alarm sounds and the display says ”AQUA”, rinse the oven chamber with the hand

shower.

Never use high-pressure cleaner. Never spray water directly on heating
elements behind the filter housing.

2. Cleaning behind filter housing

For a more thorough cleaning of the oven compartment, the filter housing is removed so that it is
possible to clean at the fan and the heating elements. You loosen the 2 screws (A) and (B) on the
filter housing. The filter housing is demounted by lifting it up till it is clear of the bottom pin and then
tipping it.

20

Combi-Oven Maintenance

3. Cleaning of Nozzle

The water nozzle can be dismounted and cleaned according to needs. The easiest way of cleaning
the nozzle is by soaking it in scale remover for approx. 6-8 hours. When remounting the nozzle, note
that the small notch will turn upwards, see the figure below.

4. Exterior Cleaning

The oven cabinet is washed with soapy water and then dried with a soft and moist cloth. After drying,
steel oil is to be added (refer to directions on the packing). Note! The exterior of the oven is never to
be flushed with water hose or high-pressure cleaner which may damage the ele ctronic components

.

Troubleshooting

Error Codes

The BKI Combi ovens have an automatic error detecting system. In the event of malfunctioning of the
oven or faulty connection, error codes (for S or VS controller) or messages (for CVC controller) appear in
the display. This means that any defects are specified immediately and can be remedied quickly and
efficiently, which again means fewer interruptions of operation and thus fewer service calls. The following
list of error codes provides you with a brief description of each error code and an indication as to how the
fault can be remedied.
