1. GENERAL RULES
Carefully read the warnings listed below as they provide important information regarding the rules for
installation, use and maintenance.
Please keep this manual carefully for further reference.
1.1 INSTALLATION STANDARDS
Install the dosing pump so that it is easily accessible whenever maintenance is required. Never
obstruct the place where the dosing pump is located.
The servicing and maintenance of the dosing pump and all its accessories must always be carried out
by qualified personnel.
AQUA SpA cannot be held responsible for damage to persons or things caused by poor installation or
incorrect use of the dosing pump.
Check that the ground is fully functional and corresponds to the regulations in force. Make sure
there is a high sensitivity differential switch (0.03 A). Check that the pump ratings are compatible
with those of the mains supply. Never install the pump directly in parallel with inductive loads
(eg motors / solenoid valves) but if necessary use an "insulation relay". Inside the pump there
are two protections: a varistor and a fuse.
THE EQUIPMENT, SUBJECT TO THIS DOCUMENT, ARE NOT INTENDED TO BE
INSTALLED AND USED IN EXPLOSIVE ATMOSPHERE ENVIRONMENTS. IT ISN’T
AN ATEX PUMP.

R: relay
I : Switcher or multi-pole

2. OPERATION
The HC151+ / HC200+ pH(Rx)-CL(J) digital pumps are solenoid dosing pumps with integrated measuring
controller that can monitor and modify the chemical-physical parameters (such as pH, redox or chlorine) of the
water to be treated. The pumps have two BNC connectors: one for pH or Redox electrode connection, the
other for connecting a level sensor. For the connection of a Chlorine sensor, the pump is equipped with a 4-
way connector. The pump is also designed to connect a PT100 temperature sensor and a proximity sensor
(not included in the package) to monitor the temperature and the presence of flow inside an electrode holder.
