International Conversions; Fitting The Suction Tube; Adjusting The Injection Rate - dosatron D 20 S Manuel D'utilisation

INTERNATIONAL CONVERSIONS

Principle : setting at 1% ⇒ 1/100 = 1 part of concentrate for 100
parts of water.
ex. : setting at 2% ⇒ 2/100 = 2 parts of concentrate for 100 parts
of water.
Ratio ⇒ 1/50.

FITTING THE SUCTION TUBE

If the Dosatron has already been used, please impera-
tively refer to § PRECAUTIONS.
- Unscrew the nut (Fig. 12-C) at the bottom of
Fig. 12
the injection assembly and put it onto the tube.
- slide the tube onto the barb as far as it will go,
tighten the clamp.
C
ADJUSTING THE INJECTION RATE (with pressure off)
IMPORTANT ! Use no tools. Adjustment must be made when
there is no pressure in the Dosatron.
- Bring the bypass button
into the median position.
- Unscrew the blocking nut
B B
(Fig. 13-B).
- Keep it fixed while screwing
or unscrewing the transpa-
rent ring (Fig. 13-D).

- adjust the guide mark
(black line) of the trans-
parent ring on the chosen
Fig. 13
dosage.
- tighten the blocking nut
(Fig. 13-B).
REMINDER: the quantity of injected product is proportional to the
quantity of water entering the Dosatron. 1% ⇒ 1/100, which means
100 volumes of water + 1 volume of injected products.
