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.

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.
Set the power using the power selector switch before
connecting the wires to the mains connection terminal:

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.

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.
Explain the operation of the continuous-flow heater to
the user.
If the continuous-flow heater does not have sufficient
A
water flow due to low water line pressure in your do-
mestic plumbing system, remove the flow-rate limiter.
