USE
The appliance is designed to operate with fluids whose temperature must
not exceed 40°C or 104°F (motor fluid, additive, fluid/additive motor mixture).
Protect installations from frost if they are likely to operate at temperatures
below 5°C (41°F) (see § PRECAUTIONS). These dosing pumps are designed
for use at pressures of up to 8 bar [116 psi]. The installation must be protected
against any risk of overpressure. The installation must also be dimensioned to
prevent any oscillatory hydraulic phenomena (water hammer). If necessary, a
water-hammer arrestor has to be fitted.
ADJUSTING THE DOSING RATE (unpressurised)
IMPORTANT! No tools should be used.
The dosing adjustment must be carried out with no pressure in the system.
- Turn off the water supply and allow the pressure to drop to zero.
- Unscrew the dosing locking nut (Fig. 14)
- Turn the dosing adjustment sleeve clockwise or anticlockwise until the 2
precision indicators of the eyelet show the desired dose rate. (Fig. 15) .
- Retighten the dosing locking nut (Fig. 16).
