7.3 Commissioning with Chemicals
Precondition for action:
✓
Easyzon
control configuration complete
✓
Unit &
dosing water purge tests complete
✓
Easyzon unit i
n Manual Inhibit Mode
Chemical commissioning steps:
1.
Connect each chemical precursor suction tube
line to the
Easyzon D.
The following chemical
configuration is compulsory:
•
Acid
– left hand suction inlet
•
Chlorite
– right hand suction inlet
2.
At the control panel activate the Prime System
mode by ac
cessing ‘Service Menu 1’, Program
2.
Set the Prime System value to ‘10’ and press
ENTER. The system will now start a purge
filling cycle.
3.
After the purge cycle has completed, at the
control panel release the Manual Inhibit mode
to allow the
Easyzon D
to commence
Generation mode.
4.
Allow the
unit
to generate until tank full status
is indicated on the control display. This is to
ensure the system safely stops the generation
mode on reaching full batch tank level.
5.
Proceed to operate the dosing pump(s)
connected to the
Easyzon D,
ensuring that
the corresponding dosing injection point
valve is open.

Chemical commissioning complete.
DANGER!
Risk of explosion due to ClO
2
gas!
The two chemical precursors, hydrochloric acid (HCl)
and sodium chlorite (NaClO
2
) almost instantly form
large quantities of toxic ClO
2
gas, which can also
decompose in an explosive manner.
•
NEVER mix the two chemical precursors,
hydrochloric acid (HCl) and sodium chlorite
(NaClO
2
), except within the
Easyzon D
process.
WARNING!
Risk of toxic ClO
2
gas release!
When handling chemicals it is easy to make
mistakes. Toxic ClO
2
gas will release from accidental
mixing of chemicals and/or through careless
spillages.
•
Never pour chemicals from one canister drum
into another canister drum.
•
A chemical precursor day tank must be refilled
with the same chemical precursor canister
drum.
WARNING!
Risk of contact with toxic ClO
2
solution!
If system leaks occur, toxic ClO
2
solution can
escape.
•
Under no circumstance must the dosing pump
maximum permissible pressure be exceeded.
•
Entire installation must remain leak free in
operation.
CAUTION!
Risk of equipment starting automatically!
NB: T
he
Easyzon D &
the dosing pump(s) are two
separate pieces of equipment with respect to the
chlorine dioxide treatment/process on site.
•
The
Easyzon
system operates automatically
when the batch tank is running low.
•
The dosing pump(s) will automatically respond
to the treatment/process conditions on site, e.g.
water meter signal input and/or analyser signal
input.
