Connection of the injector to a 2" line
Note the direction of the water flow. Assemble the injector with the arrow stamped on the body of
the injector pointing in the direction of the water flow. Connect the injector using the plastic
couplings.
For a drinking water line all injectors must have a backflow prevention valve installed in front of the
injector on the main water line, in accordance with local regulations.
Connection of the injector to a 63mm plastic pipeline
Note the direction of the water flow. Assemble the injector with the arrow stamped on the body of
the injector pointing in the direction of the water flow.
Cut and round the edges of the inlet and outlet pipes. The distance between the end of the inlet
pipe and the end of the outlet pipe should be 22cm.
Remove the 63mm nut and the white ring from the injector, and fit them on to the pipe a short
distance from the end.
Check that inside the injector there is the
seal for 63mm accessories and that the
bushing for the 63mm seal closes it from
the outside.
Insert the pipe into the inlet and outlet
opening and push hard so that the pipe
penetrates, and passes the seal, and is
stopped at the end of the route. To ease
Insertion apply a little silicon grease to
the end of the pipe.
Push the white ring until it contacts the
threaded part, and tighten the nut.
Repeat the process in order to connect
the pump to the pipe on the other side.
* Optional Special grip ring for P.V.C pipes
Installation of the injector on a direct line
It is recommended to fit a main valve at the beginning of the line (1), and a water filter of 200
mesh (2). A backflow prevention valve (3) must be fitted to a drinking water line, in accordance
with local regulations, in order to prevent entry of chemicals into the drinking water. Then place
the following pressure reducer (4),
to protect the injector from excess
pressure; a valve before the inlet to the
injector (5); a valve after the outlet (6);
an anti vacuum valve (7) to prevent a
siphon effect when the injector is not
working; and operating valves (8) for the
branch lines.
It is advisable to add a bypass pipe (9)
that will permit diverting the water flow
through the bypass pipe if there is a need
for irrigation without any additives, or for
dismantling the injector.
