GENERAL SAFETY INFORMATION
INTRODUCTION
The pH -/+ 220 series electromagnetic dosing pumps are ideal for dosing liquid chemicals in
swimming pool installations. Each pump comprises 3 components:
- The casing
- The electronic circuit
- The electromagnetic pump
THE CASING:
The series pH-/+ 220 dosing pump is housed in a polypropylene casing that guarantees IP65
protection. Featuring two apertures separated by a distance of 63 mm, it is designed to be mounted
on a wall.
ELECTRONIC CIRCUIT:
The control circuit determines the electromagnetic pump’s rest and operation cycles.
THE ELECTROMAGNETIC PUMP:
The electromagnetic pump features a maximum flow rate of 2l/h and a back pressure of 2 bar.
The pH-/+220 dosing pump is designed to monitor and regulate the pH of swimming pool water.
The pH -220 version may only be used to dose pH minus to lower the pH of swimming pool
water, while the pH +220 version is intended to dose pH plus in order to raise the swimming
pool water’s pH.
Programming and information is viewed by means LEDs on the display panel. Dosing is
proportional.
To facilitate priming, the pump may be activated manually (see the section on Priming the pump).
In the event of an emergency of any type within the plant room where the pump is installed, cut the power
supply to the installation immediately and disconnect the pump.
In installations where highly dangerous chemicals are in use, safety protocols concerning said chemicals
must be strictly followed.
For dosing pumps installed outside the EU, follow the safety standards in effect in the country of installation.
The manufacturer of the dosing pump declines all responsibility for any injury to persons or damage
sustained by equipment imputable to the non-compliant or faulty installation or operation of this product.
Caution
Install the dosing pump in a way that facilitates access for maintenance or any other intervention.
Never block or obstruct the access to the dosing pump. Install an “interlock” device to automatically inhibit
the pump in the event that the flow rate drops to a dangerously low level.
Dosing pump maintenance and cleaning interventions must only be carried out by qualified personnel.
Prior to any maintenance intervention, always drain the dosing pump tubes and unions.
Always drain and wash out tubes that have contained dangerous chemicals. Use the safety equipment
recommended for the safe handling of such chemicals se set out in their material safety data sheets.
Always read the chemical properties and technical data of the reagent used very carefully.
