Startup/additional information
(Figure VI)
The device is compliant to IEC 61000-3-12.
First start-up
w
Switch on the fuses.
w
Setting the temperature.
w
Starts rinsing: Open the warm water tap and allow
water to flow for at least 1 minute (flow-rate at least
6 litres per minute). Only then (for safety reasons)
will the appliance begin to heat.
Tip: Should the appliance not start because of a re-
duced flow-rate, remove the perlator, shower head or
similar before start and repeat the process.
w
Remove the flow-rate limiter
water pressure.
w
Explain the operation of the continuous-flow heater to
the user.
w
If the continuous-flow heater does not have sufficient
water flow due to low water line pressure in your do-
mestic plumbing system, remove the flow-rate limiter
(Figure A).

Priority circuit for the combination with electrical
storage heaters (Figure B):
For operation with a priority circuit, a special load shed-
ding relay BZ 45L20 (special accessory) is required.
Other existing load shedding relays, with the exception
of electronic load shedding relays, may malfunction.
The control electronics must be coded when operated
with a load shedding relay (Figure C).
