INSTALLATION & 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 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 foil has been removed the surfaces are vulnerable to

once sharp objects such as tools.

Remove all packaging material that secures the racks in the oven chamber.

NOTE:

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 to fit the trolley for rack.

CAUTION: The oven should be placed 2” (5 cm) from the rear wall and the distance

between the right side of the oven and the nearest wall or piece of furniture, etc.

Water connection

Combi King ovens have one or two water connections.

To facilitate cleaning and service, the oven should be connected with an approved flexible ½” hose and the permanent installations should be fitted with a stop-tap and a non-return valve. Before connecting the oven to water, flush the tubes thoroughly. Connect

Hardness of the water: max. 3 dH Conductivity: min. 75 microsiemens Water pressure: min. 2.5 bar (36.3 psi) dynamic pressure (when CombiClean activated).

When CombiClean not activated: min. 1.5 bar (21.8 psi), max. 6 bar (87 psi). Water temperature: max. 68°F (20°C) Chloride concentration: max. 100 mg/litre Sulphate: max. 150 mg/litre (.125 lb./gallon)

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

CAUTION: If the water temperature exceeds 68°F (20°C), problems with regard to

ClimaOptima calibration and cooling of the oven may occur.

CAUTION: 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.

CAUTION: The water connection must be carried out by an authorised plumber in accordance with existing rules and regulations.

CAUTION: Clogged up water filters and dirt in the solenoid valves are not covered by the warranty.

Exhaust

The BKI 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 ordered from BKI. The scope of supply also includes a specially designed extraction hood, see adjacent illustration.

If an extraction hood is installed in the ceiling above the oven, it should project 20” (50 cm) over the front of the oven. The suction
