Putting the Dosatron
into order

USING FOR THE FIRST TIME

- Open the water inlet valve slowly, the DOSATRON is self-priming.
- Operate the DOSATRON until the product to be injected is drawn up into the
injection stem (the product is visible through the plastic tube).
- The DOSATRON makes a characteristic "click-clack" noise when working.
NOTE: The time required to prime the suction hose depends on water flow-
rate, ratio setting and length of the suction hose. To bleed air from the
suction hose and accelerate priming, set injection rate at maximum. Once
the DOSATRON is primed, adjust to the required injection rate (see §

ADJUSTING THE INJECTION RATE).

Maintenance

RECOMMENDATIONS

1 - When using soluble products to
be made up into solutions, we recom-
mend the periodic dismantling of the
entire injection part
(see : § CLEANING
AND REFITTING THE
SUCTION VALVE
§ CHANGING SEALS IN
THE INJECTION ASSEMBLY).
Thoroughly rinsing all the ele-
ments of the injection part
with water and re-assembling
them after having previously
lubricated the seal (Fig. 7)
with a silicone lubricant, in the
case of difficulty in re-fitting.

2 - Before putting the DOSATRON into
operation after a non-use period,
remove the motor piston and soak it
into lukewarm water
< 40° C [104°F] over-
night. This helps to
dissolve any deposits
which may have dried
onto the motor piston.

HOW TO DRAIN THE DOSATRON

(In case of freezing temperature)
- Turn off the water supply.
- Remove the injection assembly, see
§ CHANGING THE MOTOR PISTON.
- Remove the top cap and the motor
piston.
- Disconnect the water inlet and out-
let fittings.
- Remove the pump body from the
wall support, unscrew the top cap
and empty any remaining water.
- The DOSATRON can now be reas-
sembled, having first cleaned the
seal (Fig. 8-N).

FITTING THE SUCTION TUBE

If the DOSATRON has already been
used, please imperatively refer to:
PRECAUTIONS.
- Unscrew the nut (Fig. 9-E) at the
bottom of the injection assembly
and put it onto the tube.
- Push the tube onto the barbed fit-
ting as far as it will go and screw up
the nut by hand.
- Identical process for viscous pro-
ducts option (Fig. 10-E).
