not be exceeded under any circumstances:
• Pump pressure, max. 21 bar (MP) or
14 bar (LP)
• Drinking water amount, max. 650 l/h
• The concentrate amount must not exceed the operational start-up value
The system reacts somewhat timedelayed to alterations of the regulation
i
valves. Therefore carry out the adjustment at the pressure control valve (14)
and at the concentrate control valve
(13) only in small steps, and wait until
checking the respective effect.
(1) Flow of drinking water has decreased
from _____ to _____ l/h
Read off the amount of drinking water at the flow
meter (42) and compare with the value taken
when starting operation (see operational start-up
record).
If the flow of drinking water has decreased to _____ l/h , the following fine
adjustment is to be carried out.

(2) Metered Addition
For mixing of the chemical, only unchlorinated drinking water may be
used.
This water is taken from the drinking
water sampling valve (44).
44
The metered addition is carried out dependent of
the level in the metering container.
Completely emptied metering container:
• Fill 10 l of drinking water into the metering container.
• With a measuring cup, measure the 7.5 -fold
amount mentioned in the “10 Liter Water” column of the respective chemical and fill into the
container.
• Fill the container with drinking water to the “75
l” mark and mix according to Section 3.1.2.
Partially emptied metering container:
• Read off the level of the fluid with help of the
scale at the metering container, e. g., 35 l.
• Determine the quantity to be refilled by subtracting the read level from the 75 l.
Example: 75 l - 35 l = 40 l.
• Determine the required amount of the respective chemical from the metering table.
Example: 4 x the amount for 10 l water.
• Measure the determined amount of the respective chemical and fill into the container.
• Refill amount of water to the “75 l” mark and
mix in accordance with Section 3.1.2.
3.3 Switching Off the Equipment
If the equipment is not operated for
periods exceeding 14 days, it must be
