Before you start
Select a suitable location for installation of
the controller package - preferably in close
proximity to the main system, protected from
the public and extremes of the environment.
The controller display should not be exposed
to direct sunlight.
A wall area of approx. 0.75m wide by 1.0m
high at eye level is ideal for mounting your
new Aquarius controller. A minimum oor area
of approximately 1.5 m x 0.6 m below the
controller is required for the chemical tanks.
This will vary according to the number and type
of chemicals being used for dosing.
It is important to consider elements of the
surrounding environment when installing
the equipment. It is a requirement to provide
protection for accidental spills of chemicals
and that includes any leaks that can develop
from pump pressure lines. Some corrosive
chemicals will damage materials used in
construction of buildings, particularly roong.
Never assume that the equipment will not leak.
It will occur under certain conditions. It is the
responsibility of the installer to ensure that
such events do not create damage that could
be avoided by correct site selection and the
provision of adequate bunding at the time of
installation.
System requirements
There are several minimum requirements that
should be established BEFORE the controller
is installed;
• Minimum 20 mm (3/4) take-off and line to
supply sample water to the system,
• Minimum 12 litres/minute supply ow to
ensure proper operation of sample readings,
dosage and bleed off rates.
• Adequate bunding is provided for the system
and chemical drums to prevent spills causing
damage.
• Availability of approved connection to
power. A ‘clean’ 220 - 250 vac 50 Hz @
10 amps supply (some options may need
more than one outlet, or increased current
capability).
The terminal strips supplied with the controller
activate a 240V AC supply rated @ 7A
combined. These terminals are active when
the Relay Output for the specic function is
activated, eg, pH terminal will go active 240Vac
when the pH monitored value is outside the
set-point. These outputs should be wired by
a qualied electrician. The Neutral and Earth
connections for each output must be connected
to the commoning blocks using the terminals.
To install
Unpack the equipment and check for any
damage. Ensure all parts are accounted for.
Assemble the inlet and outlet PVC valves on
the sensor manifold.
Remove the protective cap and t the pH/ORP
probe into the manifold.
Connect a 20 mm line from the circulating pump
discharge line, or system common discharge
header, to the inlet of the manifold. Connect
a return line from the manifold outlet valve
preferably in PVC pipe to the pump suction or
common suction header or to the tower basin.
Connect a line from the Bleed solenoid to an
approved waste discharge
If installing a BCD Feeder, assemble the BCD
feeder as per its separate instructions and oor
mount in the vicinity of the system. Plumb from
the BCD control solenoid to the inlet of the BCD
feeder and from feeder to the system.
Install chemical tanks as required, and ensure
each dose pump discharge tubing is connected
to the manifold injection points provided.
Run a ow of water through the system under
normal operating pressures. Check for, and
repair any leaks.
The Aquarius Controller is now ready for use.
Liaise with your chemical specialist for advice
regarding any bunding requirements, oor
drainage requirements and fresh water supply
in the vicinity of chemical tanks.
In addition check on local authority regulations
for discharge of trade waste, chemical storage
and hazards control etc.
