4.4 Type of dosage
The default dosage on the pH Perfect is acid (injection of pH minus) (E).
To change it when in the “Settings” menu, enable the option list by pressing the
“CAL/Enter” button (a small arrow appears on the right of the screen and the
type of dosage fl ashes). Then select the dosage using the “
p
” and “
q
” navigation
buttons.
Accept the choice by pressing the “CAL/Enter” button.
4.5 Alkalinity level
The quantity of corrective fl uid potentially injected can be modifi ed to take into account the alkalinity
of the water (total water hardness).
To change the value of total water hardness, from the « Settings » menu, activate the choice list by
pressing the “CAL/Enter” key (a small arrow appears on the right of the screen) then select the level
using the “
p
” and “
q
” navigation keys.
Validate by pressing the “CAL/Enter” key.
Indication of the choice of alkalinity level:
-
TAC < 100 ppm
= Low
-
100 < TAC < 150 ppm
= Std (Standard = default setting)
-
TAC > 150 ppm
= High
4.6 “OFA” over-feed protection
Your pH Perfect is equipped with protection to prevent over-feeding with
liquid chlorine in the event of a problem on the pH sensor, for example.
The purpose of this protection, called “OFA” (Over Feed Alarm), is to pause the
appliance if it has not reached the set point at the end of the time; set by default
at 4 hours (F).
The “OFA” over-feed protection functions in 2 steps:
#1: “
OFA alarm
” fl ashes on the LCD screen after 70% of the OFA programmed
time has been used without reaching the set point. However, the appliance
continues running.
#2: “
Stop OFA
” is displayed on the LCD screen after reaching 100% of
the OFA programmed time (4 hours in the original setting). The appliance
is then safe.
To cancel this protection and start your pH Perfect, press the “CAL/Enter” button (possible on the 2
steps of the OFA alarm).
Make sure that the pH sensor is in good condition. If necessary, clean and/or recalibrate it.
The over-feed protection is set by default for a maximum time of 4 hours.
It is possible to adjust it from “OFF” (disabled) to “6 hours” by intervals of 1 hour.
A fairly high setting is strongly recommended to avoid any inopportune and/or unjustifi ed start.
To regulate the OFA when in the “Settings” menu, enable the option list by pressing the “CAL/Enter”
button (the value in hours fl ashes). Then select the value chosen using the “
p
” and “
q
” navigation
buttons.
The adjustment is made by intervals of 1 hours.
Accept the choice by pressing the “CAL/Enter” button.

Special functions of the OFA
To prevent “false” alarms just after installing a pH Perfect (if the pH is poorly balanced and the chlorine
needed therefore high), the OFA may be temporarily disabled for 24 or 48 hours:
Presser Press “
p
” & “
q
” & “CAL”: OFA disabled for 24 hours (automatically
re-enabled).
PresserPress “
p
” & “
q
” & “SET”: OFA disabled for 48 hours (automatically
re-enabled).
4.7 Type of calibration
Your pH Perfect is calibrated by default in 2 steps: pH7 and pH4 (G).
This can be done in a single step on pH7 (faster but with lower measurement
reliability over time). It is also possible to remove it (strongly recommended to
avoid doing so, except for pools with a maintenance contract).
To change it when in the “Settings” menu, enable the option list by pressing the
“CAL/Enter” button (a small arrow appears on the right of the screen and the
type of calibration fl ashes). Then select the type chosen using the “
p
” and “
q
”
navigation buttons.
Accept the choice by pressing the “CAL/Enter” button.
If calibration is done in one step, the procedure described in paragraph 3.1. will automatically stop at
the end of calibration with solution 7.
4.8 Detection that fi ltration is in progress
Your pH Perfect is equipped by default with a double power feed for keeping the appliance live in order
to calibrate the pH sensor when fi ltration is stopped.
However, it is possible to disable this function if the electrical connection is different (work done by a
professional).
The pH Perfect no longer takes into account whether fi ltration is in progress and is likely to inject
corrective solution when there is no fl ow in the
pipes. Disabling is only possible if the mains power cable is controlled by the fi ltration.
To change this function when in the “Settings” menu, enable the option list by
pressing the “CAL/Enter” button (a small arrow appears on the right of the
screen and the status of detection of fi ltration fl ashes). Then select “ON” or
“OFF” using the “
p
” and “
q
” navigation buttons (H).
Accept the choice by pressing the “CAL/Enter” button.
4.9 Resetting the appliance
In the event of incorrect manipulation, it is possible to restore all the original pH Perfect functional
settings.
Procedure for resetting the pH:
Switch OFF the appliance.
> Switch ON the appliance by pressing simultaneously on the two “
p
” and “
q
” navigation
buttons (keep the buttons pressed until the message appears on the screen).
Select “Yes” or “No” using the navigation buttons, then accept using the “CAL/Enter”
button.
All the factory settings will then be restored.
