6.2 Water inlet
Water inlet implementation
Mount waterfilter (2) close to pump station
(10) following these steps:
»
Transfer mounting bracket (3) hole
pattern to a suitable location on wall.
»
drill holes, dowel and attach moun-
ting bracket with the mounting mate-
rial included with the water filter.
»
Screw T-piece included in water
connection set to water filter outlet
and affix pressure gauge.
»
Connect open T-piece outlet with
pump station using the water con-
nection hose supplied.
»
Connect the external feed water line
to the input side of the water filter
(¾ “ external thread).
6.2.1 Supply water quality
The supply water for the nozzle system must
comply with VDI 6022; i.e. from a microbio-
logical point of view it must be of drinking
water quality.
A flameresistant sampling tap
is to be pro-
vided on-site in the direct vicinity of the pump
station.
Conductivity:
5...50 µS/cm
Pressure:
0.1..0.4 MPa (1.0...4 bar)
Volume flow:
greater than the max. transpo-
ration capacity of the nozzle system
Temperature:
5...15 °C
pH value: 7 +/-1
6.3 Water drain
At the bottom of the housing, a 1¼
“spout
sticks out as a water drain used for :
•
emptying and relieving the pressure
lines to the spray system after the en-
abling signal has been removed
•
draining the flushing water from the
feed water line in a flushing process
•
drain leakage water that may occur
from the pump station
Implementation of the water drain
»
1¼
“ water hose (8) is attached to
the 1¼
“ spout on the bottom and
fastened with a clamp. The 1¼
“
water drain hose must show a con-
stant decline towards the drain (9),
must include a siphon and allow for
free draining.
