ASSEMBLING THE DOSATRON (cont...)
For connecting to polyethylene 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 polyethylene
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 put-
ting into operation.
the ferrule made of polyacetal will
not adhere to the PVC glue and can
therefore be dismantled easily at a
later date.
