WARNING!
Before carrying out ANY work inside control panel of the PoolDose
device, make sure you disconnect it from the power supply.
Failure to comply with the instructions contained in this manual
could cause injury to people and/or damage to the appliance and the
system.

WARNING!
These products are DANGEROUS (IÓA) and require special precautions during use, handling and storage.
• NEVER mix chemical products.
• NEVER allow children or people who have not read this manual to use or tamper with PoolDose or any
of its peripheral components (including chemical products).
pH chemical products:
• ABSOLUTELY not recommended => pure sulphuric acid
• Recommended for lowering pH => negative pH (with a sulphuric acid base)
• Recommended for raising pH => positive pH (sodium carbonate or bicarbonate)
ORP chemical products:
• ABSOLUTELY not recommended => all types of organic chlorine
• Liquid chlorine or 12% bleach can be used neat. If the product has a concentration of 48%, it is necessary to
dilute it in water in a 1:3 ratio.
The pH / ORP probes are subject to wear and tear and therefore are not covered by the warranty.
2. INSTALLATION INSTRUCTIONS
Use with salt chlorinator:
For the pH systems, to prevent the
risk of system malfunctioning or
damage, observe the following
instructions:
1. Position the pH measuring
probe prior to the chlorinator
cell.
2. To eliminate eddy currents,
connect the pool water to an
electrical ground point
3. Position the product injection
point after the chlorinator cell.
The probe’s angle of
inclination must never
exceed 45° from
vertical.
For optimum probe
reading, position it
perpendicular to the
tubing.

Warning!
Make sure that the injection pressure is below 1.5 bar

Alarm for the pH/ORP Set Point
When the alarm band is set, a work window is created. If the allowed limits are exceeded the alarm relay closes
and remains closed until the measurement is reset or is pressed to deactivate the alarm.
When the OFA time (Over Feed Alarm) is set, the dosing time of Set Point pH/ORP in time is controlled with two
alarms:
Ø First alarm at 70% of the time set is seen on the display, the alarm relay closes.
Ø Second alarm at 100% of the time set is seen on the display and the alarm relay closes and the
pH/ORP pump is blocked.
Press to eliminate the alarm and initialize the OFA time.

13. HANDLING
Hose replacement:
Open the pump’s lid and release the
hose by pulling the left connector
upward.
Position the roller at 7h05, turning it
in the direction of the circular arrow.
Completely release the left
connector, holding it taut towards
the outside, and turn the roller in the
direction of the circular arrow so that
the hose is freed up to the right
connector.
Position the roller at 7h05, turning
it in the direction of the circular
arrow.
Insert the left connector into the
relative housing and pass the hose
under the roller’s guide. Turn the
roller in the direction of the circular
arrow, simultaneously accompanying
the hose into the pump’s head, until
the right connector is reached.
Close the pump’s lid and press its
surface hard so that it is properly
locked into place.

14. STORING THE PUMP AFTER USE
When the regulation device must be stored, clean water should be pumped through the hose in order to rinse it.
Then position the roller at 7h05, turning in the direction indicated by the circular arrow.
These two precautions will facilitate the subsequent reactivation of the unit.
