Congratulations on purchasing this Ufesa appliance. You
have acquired a top-quality product, which will give you a lot
of enjoyment.
Please read this installation and operating instruction
manual carefully, then act accordingly! Store for future
reference.
Installation instructions
Install the continuous-flow heater as described in the
illustrated section. Observe the instructions in the text.
The illustrations can be found in the centre of the instruction
manual.
Installation
I. Unpacking/Removing the cover
■ Unpack the appliance and check for transport-related
damage.
■ Please dispose of the packaging, and if applicable, the old
appliance in an environmentally-friendly manner.
II.
Preparations for installation
Important: Only use the supplied installation set.
The supplied water connection nozzles must be installed!
■ Shut off water supply. The electrical connection (connec-
tion cable) must be disconnected from the power supply.
Unscrew the fuse or switch off the circuit breaker.
III.
Wall mounting
■ The continuous-flow heater must be mounted on the
wall. Attach it if necessary on the lower adjustable screws.
■ The distance to the wall is variable. You can compensate
for any unevenness of the wall’s surface.
■ The grommet must tightly surround the connection cable.
If it is damaged during mounting, the openings must be
provided with watertight sealing.
IV.
Water connection
■ The continuous-flow heater must be vented. The
warm water tap must be opened and the appliance
must be flushed out thoroughly for 1 minute with
at least 6 litres of water.
V.
Electrical connection/Mounting
■ The electrical supply terminal can be fitted at the top or
bottom. The sheath of the connection cable must extend
for at least 40 mm into the appliance.
Installation note
■ The installation of non plug-in ready appliances must be
undertaken by the respective utility operator or by a quali-
fied specialist company, who can also assist you when
you are requesting the approval of the utility company for
installation of the appliance.
VI.
Startup/additional information
The device is compliant to IEC 61000-3-12.
First start-up
■ Switch on the fuses.
■ Set the temperature.
■ Start 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 reduced
flow-rate, remove the perlator, shower head or similar before
start and repeat the process.
■ Remove the flow-rate limiter (see Fig. A) with low water
pressure.
■ The factory-installed flow rate limiters are designed for
an ouflow temperature of approx. 42 °C (e. g. bathing and
hand-washing temperatures). If higher outflow tempera-
tures are desired, install the separately enclosed flow rate
limiter (Fig. A).
■ Explain the operation of the continuous-flow heater to
the user.
A
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.
B
Priority circuit for the combination with electrical
storage heaters:
For operation with a priority circuit, a special load
shedding relay BZ 45L20 (special accessory) is re-
quired. Other existing load shedding relays, with the
exception of electronic load shedding relays, may
malfunction.
C
The control electronics must be coded when operated
with a load shedding relay.
