1 INTRODUCTION
Thank you for having purchased an Aqua product.
The HC150 / HC101 series solenoid driven dosing pumps represent the ideal solution
for dosing small amounts of chemical products.
The pumps are regulated through analogue controls, including a two-colour LED and a
regulating knob.
The HC101 model has also a mechanical stroke length facility included in addition to
the on/off switch and electronic stroke frequency control function. The operator may
now make an extra manual mechanical stroke length adjustment to the dosing pump,
thus further increasing the pumps accuracy, and greatly increasing the "turn down
ratio" to achieve much lower dosing rates. The stroke length adjustment should only be
made when the pump is running, and is achieved by pushing and turning the knob.
There are 20 settings available between 0% and 100%.
NB. Below 10% the adjustment will not be linear.
The figure shows the large adjustment knob of the mechanical stroke length, in a central position:
