Putting the Dosatron
into service
PUTTING INTO SERVICE FOR THE FIRST TIME
- Partially open the water inlet.
- Press the bleed button on the top cap (Fig.10).
- When a constant flow of water is seen coming from
around the bleed button (no more "spitting" of air),
release the button.
- Slowly open the Dosatron By-pass valves and close the
main valve
- Slowly open the fast priming valve situated downstream
of the Dosatron (Fig. 9 Page 22)
- Operate the DOSATRON until the product to be dosed
rises in the dosing part (the product is visible through
the plastic hose), then close the fast priming valve.
- The DOSATRON makes a characteristic "click-clack"
noise when working.
NOTE:
the time required for priming the dosed solution depends on the
water flow, the dosing adjustment and the length of the suction hose for
the product.

USE

The device is designed to operate with fluids the temperature of which
must not exceed 40°C or 104°F (engine fluid, additive, mixture engine fluid/
additive). In the event of installation subject to operating at temperatures
less than 5°C (41°F), protect the installation from frost (see precautions
instructions). The dosing pumps are designed for use at up to 6 bars. The
installation must be protected against any overpressure risk. The installation
must also be sized to avoid any hydraulic oscillatory phenomenon (water
hammer). If necessary, a water hammer protection device should be fitted.

ADJUSTING THE DOSING (unpressurised)
IMPORTANT! Do not use tools.
Dosing adjustment must be made unpressurised.
- Turn off the water inlet and allow the pressure to drop to zero.
- Loosen the dosing locker (patented system) by a quarter turn (Fig. 11).
- Screw or unscrew the dosing adjustment sleeve in order to line up the 2
eyelet points with the desired dosing marker (Fig. 12).
- Retighten the dosing locker (Fig. 13).
