The DOSATRON dosing rate can be adjusted according to two scales:
percentages and ratios. These scales are positioned on either side of the
dosing part. Depending on the water circulation direction in the hydraulic
installation, and on the direction in which the dosing pump is mounted on its
bracket, it may be necessary to change the orientation of this scale.
- Lift the quick coupling ring
(patented system) and unlock the
dosing part by unscrewing the
ring as far as the mechanical stop
(approx. 1/8th of a turn) (Fig. 2).
- Pull downwards and rotate a half-
turn to release the dosing part to
see the correct dosing adjustment
scale.
- Insert the dosing body into the
pump body taking care to align the
aligning pins.
- If needed, to see the pins better,
unscrew the dosing adjustment
sleeve so as to reach the value of
3% or 1/33 (Fig.3).
- Push the quick coupling ring
towards the pump body and lock
in place by tightening the ring until
it clicks (approx. 1/8
th
of a turn)
(Fig.4)
The DOSATRON is delivered with a suction hose (cut it to the required
length). This hose must be fitted with the strainer and ballast.
NOTE: The maximum suction height is 4 metres (13 feet).
- Unscrew the hose nut (Fig. 5) at the bottom of the dosing part and fit it
over the hose.
- Push the hose into the barbed fitting as far as it will go and screw the nut
by hand (Fig. 6).
- Assemble the strainer on the other end of the hose (Fig. 7) using the same
method.
- Immerse the strainer into the solution to be dosed.
