6
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
3
/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 5 minutes after the program is finished.
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. COUNTER-
CLOCKWISE.
If the fan rotates in the wrong direction, the oven does not operate correctly, which may cause damage to
the oven.
