PREMIÈRE MISE EN SERVICE
ATTENTION: Check that the bypass
is in “ON”-position.
- Partially open the water inlet
valve.
- Press the bleed button on the top
of the DOSATRON.
- 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 injection part (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 injec-
tion rate (see § ADJUSTING THE INJECTION RATE).
