PANNELLO A-CHLORO AW96CL–HC897
ENGLISH ENGLISH
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. 7
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. 8
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. 8) 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.
2.6 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.
