Warnings
Chemicals used as part of the treatment
program may be hazardous. Refer to the
Material Safety Data Sheets (MSDS) provided
by your chemical supplier and ensure personnel
involved are aware of the handling and safety
procedures.
Please read and understand all safety warnings
on chemical containers before servicing any
dosing equipment.
Wear as a minimum - safety goggles and gloves
when servicing the dosing equipment.
Do not mix concentrated acids and oxidising
agents as explosion, and/or toxic and lethal
gas may be evolved, and/or fire result. Keep
all chemical containers sealed and free from
contamination.
Salt water chlorinators draw high currents
when operated. The controller is fitted with a
Normally Open, Normally Closed Relay for
activating the chlorinator. This relay is suitable
to a max. of 10A. Please consult the chlorinator
specs to determine current draw. If greater than
10A, the relay may only be used to activate a
contactor which in turn control the chlorinator.
(see wiring diagram on page 9)
Regular Inspections and Maintenance
For optimum results and continued accuracy,
the complete operation of the controller system
should be verified at least on a monthly basis.
All sensors should be inspected, cleaned and
calibrated as necessary every month.
The pH/ORP sensor age with time and
temperature, and have a typical life span of 2-3
years depending on the application in which
they are operating. They should be replaced
accordingly.
Where fitted, flow sensors, solenoid valves and
wire strainers should be checked for correct
operation and cleaned of any debris every
month.
Injection non-return valves and pumps should
be cleaned and checked at least annually.
Sodium Hypochlorite being highly alkaline may
lead to scale formation on its dose injector and
this require acid cleaning on a frequent basis.
On the peristaltic dose pumps, the squeeze
tubes and roller block should be checked at
least annually and should be replaced every
1-2 years.
More regular maintenance may be required
for the larger 3.0 l/hr pumps, due to increased
pumping rates.
Chemical suction and discharge tubes
should be inspected monthly and replaced as
necessary
