Putting the Dosatron
into order

USING FOR THE FIRST TIME

- Switch the bypass button on the top of the DOSATRON to position ON.
- 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 the water
flow-rate, the ratio setting and the length of the suction hose. To bleed the
air from the suction hose and accelerate the priming, set the injection rate
at maximum. Once the DOSATRON is primed, adjust to the required injec-
tion rate (see § ADJUSTING THE INJECTION RATE).
INTEGRATED BY-PASS
- By-pass in ON position : the DOSATRON is sucking, injecting and mixing
concentrate into water at the desired percentage.
- By-pass in OFF position : the DOSATRON is not working and is not drawing up
any concentrate.

RECOMMENDATIONS

1 - When using soluble products to
be made up into solutions, we
recommend the periodic dis-
mantling of the entire
injection part (see : § CLEA-
NING AND REFITTING THE
SUCTION VALVE § CHAN-
GING SEALS IN THE
INJECTION ASSEMBLY).
Thoroughly rinse all the ele-
ments of the injection part
with water and re-assemble
them after having previously
lubricated the seal (Fig. 7)
with a silicone lubricant, in the
case of difficulty in re-fitting.

FITTING THE SUCTION TUBE

If the DOSATRON has already been
used, please imperatively refer to:
PRECAUTIONS.
1 - For D45RE1.5/IE and RE3/IE
- Unscrew the nut (Fig. 8-E) at the bot-
tom 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.
2 - For D45RE3000
- Unscrew the nut (Fig. 8-G) 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.

2 - Before putting the DOSATRON
into operation after a non-use period,
remove the motor piston
and soak it into luke-
warm water < 40° C
overnight. This helps to
dissolve any deposits
which may have dried
onto the motor piston.

3 - For D45RE8/IE
- Loose the clamp (Fig. 8-F) holding
the suction hose by means of a screw-
driver.
- Push the hose onto the barbed fitting
as far as it will go and then fasten the
clamp again.
