Cleaning Cycle
1.
Once the system is filled with
ScaleBreak®
and water, turn the
Main Pump
Switch
ON (up position).
2.
For a closed vessel, the lid of the Venting Drum should always be securely
fastened to avoid splash.
3.
Make sure
Chemical Pickup Hose
in fully inserted into chemical container.
4.
Slide
pH Controller Switch
to
“AUTO”.
5.
As scale and deposits are dissolved, the pH of the
ScaleBreak®
Decaling
Solution will tend to rise. The
pH Sensor
and
pH Controller
will sense this
and inject concentrated
ScaleBreak®
into the system, lowering the pH to the
optimal level.
6.
After one hour of no chemical injection, the
"CLEANING IN PROGRESS"
light
will go out. This generally means that all the scale has been dissolved. (no rise
in pH as scale is fully dissolved).
Venting Drum / Overfill alarm
WARNING:
In a closed vessel system, the Venting Drum serves two functions – to
vent any fumes from the descaling operation, and to provide extra volume for the
chemical injected into the system. To prevent the overfilling of the Venting Drum
if too much chemical is added, the GDS-15-PH are equipped with an
“OVERFILL
ALARM”
Lamp. Also, the GDS-15-PH has an automatic chemical pump shut-off
circuit. If the Venting Drum is full, the Chemical Pump will be disabled and will not
inject anymore chemical into the system until the liquid level in the drum
is reduced.
If the red "OVERFILL ALARM" Lamp is lit, the Venting Drum is full:
1.
Shut down the unit by turning the
Main Pump Switch
Off (down position).
2.
Slide
pH Controller Switch
to
“OFF”

Valve #2
3b. Close the valve on the hose connected to
Valve #2
, then disconnect
the hose.
4.
Open
Valve #2
(Pump Input Valve) and drain at least 5 gallons (19 L) of solution
into a suitable container.
