STAGE SIX: - Fitting 12v Electronic Attendant Control9
This control must be fitted in an easily accessible dry place for the operation of the attendant. When the control
is fitted to the wall then connect plugs coming from the control to the sockets on relay board inside left hand
of generator box. NOTE extension leads are available if required. Also make sure exposed connectors are
protected with water proof tape.
STAGE SEVEN: - Computer Management Link
You only need to connect a 2 wire lead with a gland inside lower left hand of attendant control. These wires
must go to a volt free contact at the computer, when contact is made (closed) generator will start, when contact
is (open) generator will stop. NOTE: control switch must be on timer mode and the timer switch “OFF” to
synchronies with computer. This function is available as standard on the AKW control but only by special order
on the BKW control.
STAGE EIGHT: - Power (Kilowatt) selection for BJ6-12 & BJ18-24
For BJ6-12 the fixed minimum power is 6kW. To increase to 9kW insert link pin (detail 10 Fig 2) and to increase to
12kW also insert link pin (detail 10A Fig 2). For model BJ18-24 the minimum fixed power is 18kW. To increase to
21KW fit link pin (detail 10 Fig 2), to increase to 24KW fit link pin (detail 10A Fig 2). Link pins are to prevent power
being accidentally increased. Cable should be adequately sized to suit the power requirement. Note: setting the
generator on a higher power than necessary may result in the cubicle remaining for relatively long periods at a
temperature above the set point with no steam. Only use the minimum power necessary.
STAGE NINE: - Connection to Power supply
The BJ6-12 is set for three phase but can be modified to single phase use by inserting a link connector supplied
(detail 6A Fig 2) into connector (detail 6 Fig 2). By tightening the three screws the machine will be converted into
single phase operation. The BJ18-24 is three phase only. When connecting cables to power supply it is advised
that conduit be used and connected via hole (detail 6B Fig 2) with the appropriate fitting. 220-240v AC. for single
phase, 415v AC. for three phases 50-60Hz. The steam generator must be earthed and connected to a residual
current circuit breaker with a minimum of 30 mille Amps sensitivity and connected through an isolating switch
with minimum of 3mm breakage across all poles. The correct fuse must be fitted for the power selected. For
technical specification see page 2. NOTE all mains connections must be thoroughly tightened and it is good
practice to re-tighten all power connections within the generator since copper conductors may have “eased
back’’ in their terminals in transit.
STAGE TEN: - Essence Doser unit (optional extra)
This machine is provided with a 220-240v AC. 5 amp fused terminal connector (detail 18) and PG7 cable gland
(detail 18A) for essence doser connection, this will energies when steam is produced. For further details contact
your supplier.
STAGE ELEVEN: - Commissioning Generator
Re-check that the unit is installed in accordance with the instructions before switching mains power on. Please
check that the water supply is “ON” with sufficient pressure 0.5 bar, (3 meters head). Switch power “ON” and
you will see a green light on the generator and an intermittent one on the AKW attendant control or a further
steady green light on the BKW control (that means the generator is ready to start) now follow the operating
instructions. Once the generator is operating switch off and drain the generator to clean plumbing flux etc from
inside. Do this twice and finally check for leaks. If you need any further information please do not hesitate to
contact our technical department.
Please leave instructions with client and demonstrate how to de-scale the unit.
