DOSATRON INTERNATIONAL / 38

USING FOR THE FIRST TIME

- Partially open the water inlet valve.
- Press the bleed button on the top of the DOSATRON (Fig. 6).
- 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 "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).
The DOSATRON is fitted with the function by-pass.
(optional equipment) :
- By-pass in ON, the DOSATRON works and the concentrate is drawn up.
Fig. 11
- By-pass in OFF, the DOSATRON is stopped and does not draw up the
product.
