Technical Data

• Flow pressure:
min. 0.5 bar / recommended 1 - 5 bar
• Operating pressure:
• Test pressure:
If static pressure exceeds 5 bar, a pressure
reducing valve must be fitted.
• Infinitely variable flow volume of:
• Flow rate:
• Temperature:
Installation
Flush pipes thoroughly before and after
installation (refer to EN 806)!
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 flush pipe (A) as per Fig. [3].
• Connect flush pipe (A) with outlet nut (B) to
fitting, see Fig. [4].
• Open isolating valve (D) and set the desired
flow rate, see Fig. [5].
Open water supply and check connections for
watertightness!
Changing the flow volume
• Unscrew actuating cap (C), see Fig. [6].
• Change the flow volume by turning adjusting
screw.
Fault Cause
Continuous • Isolating valve (D) not fully open
running / • Nozzle blocked
persistent low • Actuaction unit damaged
water flow
No flushing or • Leather seal dry or damaged
flushing too
short • Incorrect flow volume
Water emerging • Relief valve defective
from under the
actuating cap
Operation, see Fig. [4].
The pre-set flow volume is released by pressing
down actuating cap (C) for 1 second. Following
release of this flow volume, the valve stops the
water flow automatically and without kickback.
max. 10 bar
16 bar
Maintenance
1 - 4 l
Inspect and clean all components and replace if
0.3 - 0.7 l/s
necessary.
max. 40 °C
Function parts must not be greased!
Shut off water supply or close isolating
valve (D)!
Piston
1. Unscrew actuating cap (C), see Fig. [7].
2. Unscrew actuating unit (F).
3. Remove piston (G) with spring (H).
Install in reverse order.
When reinserting, expand and moisten leather
seal (G1) and clean groove (G2), see Fig. [8].
Replacement parts, see fold-out page I
(* = special accessories).
Care
For directions on care, refer to the accompanying
Care Instructions.
Remedy
- Open isolating valve (D), see Fig. [5]
- Clean piston (G), see Maintenance
- Replace actuation unit (F), see
Maintenance
- Expand or replace leather seal (G1),
see Maintenance
- Adjust the flow volume, see Changing
the flow volume
- Replace actuating unit (F), see
Maintenance
