International Conversions; Fitting The Suction Tube; Adjusting The Injection Rate; Changing The Motor Piston - dosatron D14 MZ 3000 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 imperatively refer to §
PRECAUTIONS.
- Unscrew the nut (Fig. 11) at the
bottom of the injection assembly
and put it onto the tube.
- Push the tube onto the barbed
fitting as far as it will go and screw
up the nut by hand (Fig. 12).
ADJUSTING THE INJECTION RATE (with pressure off)
IMPORTANT ! Use no tools.
Adjustment must be made when there is no pressure in the DOSATRON.
- Turn off the water supply and allow the pressure to drop to zero.
- Unscrew the blocking ring (Fig. 13).
- Screw or unscrew the adjusting nut in order to line up the 2 peaks of the
eyelet with the desired ratio on the scale (Fig. 14).
- Tighten the blocking ring (Fig. 15).

allow the pressure to drop to zero.
- Unscrew and remove bell-housing
by hand (Fig. 16).
- Remove the motor piston(Fig. 17)
by pulling it up.
- Rod and plunger piston are fixed
to the motor piston and taken out
simultaneously.
- Change and reassemble in the
reverse order to the above.
- Refit the bell-housing (take care
not to damage its seal) and tighten
by hand.
