• Operating pressure:
• Test pressure:
If static pressure exceeds 5 bar, a pressure
reducing valve must be fitted.

Installation
Flush pipes thoroughly!
Refer to the dimensional drawings on fold-out
page I and fold-out page II, Fig. [1].
Fitting and connection
• Seal the fitting and attach, see Fig. [2].
• Cut flushing pipe (A) 10mm below the fitting,
see Fig. [3].
• Push flushing pipe (A) with seals (B) onto outlet
socket (C), see Fig. [4].
• Connect flushing pipe (A) with cap (D) to fitting.
Open water supply and check connections for
watertightness!
Isolating valve
• Remove cap (E) and open isolating valve (F),
see Fig. [5].
Changing the flow volume
The factory-set flow volume is approx. 9 litres at
a flow pressure of 3 bar.
• Unscrew actuating cap (G), see Fig. [5].
• Change the flow volume by turning adjusting
screw (H).
Fault Cause
Continuous • Isolating valve not fully open
running / • Nozzle blocked
persistent low • Piston seal damaged
water flow • Cap damaged
No flushing or • Leather seal dry or damaged
flushing too
short • Incorrect flow volume
Water emerging • Relief valve defective
from under the
actuating cap
Changing the flush flow
The restrictor is factory set to approx. 1.3 l/s
at 3 bar flow pressure.
• Changing the flush flow by turning the
restrictor (I) with enclosed restrictor tool (J),
see Fig. [6].
max. 10 bar
Operation, see Fig. [6].
16 bar
The pre-set flow volume is released by pressing
down actuating cap (G) for 1 second. Following
release of this flow volume, the valve stops the
1.0 - 1.3 l/s
water flow automatically and without kickback.
max. 40 °C
Maintenance
Inspect and clean all components and replace if
necessary.
Function parts must not be greased!
Shut off water supply respectively close
isolating valve!
Piston
1. Unscrew actuating cap (G), see Fig. [7].
2. Detach plate (K) and guide ring (L).
3. Remove threaded ring (M).
4. Unscrew cap (N) with pushbutton by using
an 24mm open ended spanner.
5. Remove piston (O) with spring (P).
Install in reverse order.
When reinserting, expand and moisten leather
seal (R) and clean groove (S), see Fig. [8].
Replacement parts, see fold-out page II
(* = special accessories).
Care
For directions on care, refer to the accompanying
Care Instructions.
Remedy
- Open isolating valve (F), see Fig. [5]
- Clean piston (O), see Maintenance
- Replace piston seal, see Maintenance
- Replace cap (N), see Maintenance
- Expand or replace leather seal (R),
see Maintenance
- Adjust the flow volume, see Changing
the flow volume
- Replace cap (N), see Maintenance
