HOW TO DRAIN THE DOSATRON (in case of freezing temperature)
- Turn off the water supply and let the pressure drop to zero.
- Remove the injection assembly, see § CHANGING THE MOTOR PISTON.
- Remove the bell and the motor piston.
- Disconnect the water inlet and outlet fittings.
- Remove the lower pump body from the mounting bracket and empty any
remaining water.
- The DOSATRON can now be reassembled, having first cleaned the seal.

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.
For Ø 16 (Fig. 11) :
- Unscrew the nut at the bottom of the injection assembly and put it onto
the tube.
- Push the hose firmly into the barbed fitting and re-tighten the collar.

1 - When using soluble products
to be made up into solutions, we
recommend the periodic dismantling
of the entire dosing part (see : §
CLEANING AND REFITTING THE
SUCTION VALVE, § CHANGING
SEALS IN THE INJECTION
ASSEMBLY).
Thoroughly rinsing all the elements
of the dosing 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] overnight. This
helps to dissolve any deposits which
may have dried onto the piston
motor.
