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 SHIPPING AND TRANSPORTING THE PUMP
The equipment must be transported in its original packaging, organized and built in such a way as to
minimize shocks and to protect the protruding parts that can be damaged. If there is a need for transport
after the equipment has already been installed (e.g. for a return for repair or replacement), reuse the
original packaging or a sufficiently sturdy packaging with the equipment protected with absorbent
material ( eg bubble wrap). The external packaging must be such as to ensure the safety of the
equipment in the event of a fall from 1 meter in height.
1.2 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.
1.3 PROPER USE OF THE PUMP
The use of this pump must comply with the methods and instructions set out in this manual.
The pump can dose chemicals that can be harmful to human health and for this reason it is essential that must
be used by qualified personnel who adopt the appropriate safety methods and personal protective equipment.
AVOID IMPROPER USE of the equipment in order to avoid damage to things and people, due to uncontrolled
splashes, drips, electrical contacts, etc.
The following uses can be considered improper uses, in indicative and non-exhaustive form:
- Dosing of products not consistent with the materials with which the pump is made;
- Dosing of explosive and / or flammable products;
- Dosing of fluids with excessive viscosity (1000 cps), such as to prevent the priming of the pump itself;
- Dosage of food liquids, if intended to maintain such use;
P: dosing pump
R: relay
I : Switcher or multi-pole
security device
E: Motor or generally
inductive charge
A: supply voltage

- Avoid inverting the pump delivery and suction;
- Avoid powering the pump with voltages other than those indicated in the technical specifications;
- Avoid connecting any equipment other than specific equipment to the signal outputs (level, pulse
counter, current signal, etc.);

2. OPERATION
The HC151+ CST HC200+ CST and HC151+ PImA analogue pumps are solenoid driven dosing pumps that
can operate at constant flow (CST version) or at proportional flow according to an external signal (PI-mA
version). Depending on the model, there may be: a BNC connector for connecting a level sensor and / or a 4-
pole connector for connection to a current signal (mA) or from a pulse-emitting water meter.

With chemical products with a different viscosity than that of water, the flow rate data may undergo even
sensitive variations.
