USING FOR THE FIRST TIME
NOTA : 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).
The injector shall be powered only with water.
Before operating the unit for the first time, it must be purged to
ensure complete ATEX compliance :
- Partially open the water inlet valve.
- Press the bleed button on the top of the DOSATRON
(Fig. 7).
- When a constant flow of water is seen coming from
around the bleed button (no more «spitting» of air),
release the button.
- 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
“clickclack” noise when working.

OPERATION
The equipment is designed to operate with fluids whose tempatures shall
not exceed 40°C (motor fluid, additive, motor fluid / additive mix). In case the
installation is potentially subjected to temperatures lower than 5°C, it shall be
drained for frost protection (see manual precautions).
The injectors are designed for operating at 8 bar maximum pressure. Thus, the
installation shall be protected against any overpressure risk. The installation shall
as well be designed in a way to prevent from any hydraulic oscillatory phenomena
(water hammer). If necessary, a protection device should be installed.
