Putting the DOSATRON
into order

USING FOR THE FIRST TIME

The DOSATRON may be fitted in its upper part with the function by-pass
(optional equipment) :
- By-pass in ON, the DOSATRON works and the concentrate is drawn up.
- By-pass in OFF, the DOSATRON is stopped and does not draw up the
product.
- 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 doser body (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 tube depends on the water
flow-rate, the ratio setting and the length of the suction tube. To bleed the
air from the suction tube and accelerate the priming, set the injection rate at
maximum. Once the DOSATRON is primed, adjust to the required injection
rate (see § ADJUSTING THE INJECTION RATE).
PRODUCT AUTOMATIC ANTI-SIPHONING DEVICE
- It automatically restores the atmospheric pressure within the system in the
event of accidental under pressure after the Dosatron.
- Remove the red cap in order to activate it (Fig. 4).
*Example of use:
- Situation in which the outlet is lower
than the inlet.
- Situation in which the water supply
shut off valve is located upstream of
the dosing unit.

RECOMMENDATIONS

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. 5) 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.

Maintenance

O-ring
- Turn off the water supply and let the pressure
drop to zero.
- Open the D30GL unit (Fig. 6).
- Remove the injection assembly, see §
CHANGING THE MOTOR PISTON.
Fig. 6
- 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.
- Close the D30GL unit (Fig. 7).
