ASSEMBLING THE DOSATRON (cont...)
For connecting to polyethy-
lene or polypropylene pipe :
- Bevel the end of the pipe and
slide on nut (Fig. 4-E) and then
ferrule (Fig. 4-C).
- slide pipes into water inlet and
outlet (Fig. 4) as far as they
will go.
- Push one ferrule (Fig. 4-C)
against the inlet and the other
against the outlet.
- tighten the nuts (Fig. 4-E).
C
the connection of the Dosatron to the water network can be done
with flexible hoses (internal diameter 50 mm) to be fixed by means
of clamps and turning adapters Ø 50 x 60 mm [2"]. Make sure the
water is flowing according to the direction arrow on the pump body.
the Dosatron is delivered with a suction hose (cut it to the needed
length) enabling its use with a large capacity concentrate container.
The hose must be fitted with its strainer.
the instructions for fitting the hose are to be found in the specific
chapter.
For connecting to PVC pipe :
- Proceed as for the polyethy-
lene and polypropylene pipes but
spread PVC adhesive on the
pipe where the ferrules are to be
mounted.
- then place the ferrules over
the pipe using both thumbs in
the slot to widen the ferrule (Fig.
4-C) and avoid scraping off the
adhesive, then tighten the nut.
NOTE : Wait for one hour before
putting into operation.
the ferrule made of polyacetal
will not adhere to the PVC glue
and can therefore be dismantled
easily at a later date.
