2.0 INTRODUCTION
The HC999 pump is a metering solenoid pump that can work in constant or proportional by an
external signal. In the bottom of the enclosure there are located an ON/OFF switch and an internal
terminal block to connect the different signals (level probe input, water meter input, flow sensor
input, 4÷20mA input and relay output)
Once the pumps is switched on the display show an user menu and is possible to read some
information regarding the functioning mode and the possibility to pause and prime the pump.
Thanks to the digital technology with the microcontroller and an LCD display the HC999 pump is
easy to program and to save all the statistics.

3.4 Electrical connection
CAUTION !!!!!
Verify that the earth system is perfectly functional and complies with the applicable
regulations. Ensure the unit is connected to a circuit protected by a highly sensitive
(0.03A) RCCB circuit breaker. If unsure please consult a competent electrician.
Verify that the rated values of the pump are compatible with those of the mains.
Never install the pump directly in parallel with inductive loads (e.g. motors/solenoid
valves) if necessary, use an isolating relay.
There are 2 protection devices inside the pump: a varistor and a fuse.
P- Metering Pump
R- Relay
I-Switcher or multi-pole security
device
E- Motor or generally inductive
charge
A- Supply voltage
3.5 Hydraulic connection
After the exact installation of the pump (see generalities), proceed with the connection.
Suction: connect the suction tube (PVC soft cristal) to the foot filter that is supplied and put it in
the hose clamp, lock the tube closing the nut. If it utilises a level probe, this one has to be
connected to the filter through the support that is supplied. Put the foot filter into the liquid suction
lift tank. Connect the other extremity to the suction of the pump (lower part of the pump head),
unscrew the nut from the nipple, take off the rubber white disk situated on the tube connection.
Let pass the tube through the nut and the adaptor for the 4x6 tube with a simultaneous action of
pressing and rotating, put the tube on the nipple conical connection (hose clamp) till the end; lock
up everything by closing the nuts well. See fig. 9
Delivery: connect the pump to the plant always through the injection valve (1/2”Gm) that is
supplied with the installation Kit. Fit a Gf 1/2” nipple on your water supply line and after that fitting,
to the point where you require chemical injection, the injection valve out with teflon and put in into
the pipe. Unscrew the nut, put well the discharge tube (stiff Polyetilene) on the hose clamp of the
nipple’s valve, lock everything by closing the nut well.
Connect the other extremity to the delivery of the pump (upper part of the pump head), by
repeating the instructions above. See fig. 9
Purge: connect another tube’s extremity for the manual purge (2 mt PVC crystal) in the hose
clamp situated on the pump head lower to the right, while the other extremity is to be put into the
suction lift tank. See fig. 10

INSTRUCTION FOR PRIMING
For the priming of the pump in case of high against pressure in the injection, turn the purge knob
for a quarter or a half of round (see fig. 10) until the head pump is completely full. Screw down
again the knob.
ATTENTION!!
If it is necessary to take the pump off the plant, it is important to put the
white disk in again, so as to avoid any exit of the liquid contained in the
pump head from dripping out. - During the installation ensure that the
discharge tubing is fixed correctly to avoid that it does not rub against hard
bodies. Avoid also use less bends both on discharge and suction tubing.
- Connect the pump to the plant always through the injection valve (1/2”Gm)
supplied with the installation kit.
- Connect the soft PVC tubing only in suction (on the foot filter side), instead
connect the PE tubing in delivery by verifying that the cut of the tubing is
clean and that lateral crushing is not caused; it is advisable to utilise a
cutter instead of scissors.
3.6 Operation
The metering pump is activated by a Teflon diaphragm mounted on a piston enclosed into a
electromagnet, which is fed by continuous current producing a square wave moving the piston
thus, a pressure is produced in the pump body with an expulsion of liquid from the discharge
valve. Once the electric impulse is over, the return of the piston is spring assisted thus producing
the suction action to the initial position, with a recall of liquid through the suction valve. The
material used for the construction of the pump makes it particularly suitable for aggressive liquids.
We suggest you in any case to use the compatibility tables or our technical department.
