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.
Refer to the dimensional drawings on fold-out
page I and fold-out page II, Figs. [1] and [2].
Fitting and connection
• Seal the fitting and attach, see Fig. [3].
• Connect flushing pipe (A) with outlet nut (B),
see Fig. [4].
• Open isolating valve (C) and set the desired
flow rate, see Fig. [5].
Open water supply and check connections for
watertightness.
Changing the flow volume
1. Remove screw (D) using a 3mm allen key, see
Fig. [6].
2. Remove actuating cap (E)
3. Change the flow volume by turning adjusting
screw (F), see Fig. [7].
Fault Cause
• Isolating valve not fully open
Continuous
• Nozzle blocked
running /
• Relief valve defective
persistent low
• Piston seal damaged
water flow
• Leather seal dry or damaged
No flushing or
flushing too short
• Incorrect flow volume
• Seal (I) incorrectly installed
• Cap seal defective
Water emerging
• Relief valve defective
from under the
retaining cap
Operation, see Fig. [4].
The pre-set flow volume is released by pressing
down actuating cap (E) 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
Inspect and clean all components and replace if
2 - 6 l
necessary.
0.3 - 0.7 l/s
Function parts must not be greased.
max. 40 °C
Close isolating valve (C)
Piston
1. Remove screw (D) using a 3mm allen key,
see Fig. [6].
2. Remove actuating cap (E)
3. Remove screws (G), see Fig. [8].
4. Remove cap (H) with seal (I), see Fig. [9].
5. Take out piston (J) with spring (K).
Install in reverse order.
When reinserting, expand and moisten leather
seal (L) and clean groove (L1), see Fig. [10].
Replacement parts, see fold-out page II
(* = special accessories).
Care
For directions on care, refer to the accompanying
Care Instructions.
