Operation - Hans Grohe 31742000 Manual

Attention! The fitting must be installed, flushed
and tested after the valid norms.
Assembly
1. Flush through the supply pipes.
2. Mount the S - unions and align them.
3. Fasten the mixer with the washers.
The hot and cold supplies must be of equal pres-
sures.

Operation

The mixer is activated by lifting the lever handle.
Turning to the left = warmer water,
turning to the right = cooler water.
31742000/31754000: The flow is changed from
bath to shower function by pulling the knop at the
upper side of the spout. After shutting off the water
flow, the mixer returns automatically to the bath
function.

To adjust the hot water limiter on single lever mixers,
please see page 23.
No adjustment is necessary when using a continuous
flow water heater.
Hansgrohe single lever mixers can be used together
with hydraulically and thermically controlled con-
tinuous flow heaters if the flow pressure is at least
0,15 MPa.
Attention!
The non return valves must be checked once a
year.
