SUCTION
It is essential to fit in the suction of the dosing liquid the filter of 100 mesh
supplied with the dosing pumpr.
To help suction the piping must be as short as possible, the pipe diameter must
be in keeping with that of the valve. For pipes over 3m, diameter must be
increased.
Couple the suction pipe to the lower connecter of the cylinder, putting the mesh
filter in between. The stuff at the bottom of the tank must never be suctioned, to
avoid taking up undiluted particles.
The piping must be stiff enough so that it does not lose its shape when there is
suction.
INJECTION
Fix the check valve supplied with the pump at the input of the water network, as
shown in the drawing, and couple the injection hose to the upper connecter of
the cylinder.
To protect the piping from the pressure variations or to achieve a continuous
flow, we suggest fitting a pulsation damper as near as possible to the pump.
In order to make priming easier, we suggest fitting a priming valve. You should
anticipate an adequate dispositive in order to collect the liquid that can get out
when priming, and derive it where it can not be harmful.
The pipe diameter will have to be the same as the valve diameter. For pipes over
15m length the diameter shall be increased. Do never insert a shutoff valve.
Install a safety valve in a derivation as near as possible from the
pump, in order to protect it and the whole installation from possible
over-pressures. This derivation must derive liquid to a safe place.
6.- START UP AND REGULATION
STAND: Check that the pump is properly installed in its stand.
OIL: Take off re-filling lid and fill the pump with the provided oil
dipstick. Approximate capacity: 100cm3 per module.

CHECKING THE HYDRAULIC CIRCUIT: Check that all valves are
opened and that escapes from priming valves derive the liquid to a
proper receptacle.
CHECKING THE PUMP: Check visually / auditorily the proper
working of the pump.
PRIMING: To prime the pump easily, especially for not very important flows
and if we do not have priming valve, we suggest to lower pressure up to the
minimum injection point. If that is not possible, fill up the cylinder and the
suction pipe with liquid.
OVER-PRESSURE PROTECTION: Adjust the safety valve over-pressure
or relief to the wished pressure to protect the installation without exceeding
the pump nominal flow.
REGULATION: Adjust the electric dispositive of electric protection to the
motor nominal current.
