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 fit the pH/ORP probe and other probes into the manifold.
Install the BLEED solenoid on the manifold and wire the power cable supplied from ULTIMA.
(Never leave the bleed solenoid cable unplugged when turning ULTIMA ON)
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.
If installing a BCD Feeder, assemble the BCD feeder as per its separate instructions and floor
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 the BCD solenoid as required and wire its power cable before plugging into the sockets
supplied inside the controller box. (Never leave the BCD solenoid cable unplugged when turning
ULTIMA ON)
Install chemical tanks as required, and ensure each dose pump’s discharge tubing is connected
to the manifold injection points provided.
Run a flow of water through the system under normal operating pressures. Check for, and repair
any leaks. The Ultima Controller is now ready for use.
Liaise with your chemical specialist for advice regarding any bunding requirements, floor
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.
Maintenance and Care of Sensors
Foulants can lead to inaccurate sensor readings. Sensors should be cleaned and calibrated
regularly using the following procedures.
Cleaning of Flow/Conductivity/Temp Sensor
Isolate the flow to the manifold. Remove the locking nut from the Flow/Conductivity/Temp sensor.
Abrade the sensor surface with 300–400 grade wet–and–dry paper until the surface is clean, the
two carbon electrode surfaces are clearly visible, and the surface wets out freely.
Ensure flow paddle is free from debris. Rinse the sensor in fresh water and replace it in the
manifold.
Cleaning of pH/ORP sensor
Isolate flow to the manifold. Remove the sensors from the manifold by loosening the lock
nut and withdrawing the sensor from the manifold.
Rinse the sensors in fresh tap water and remove any visible fouling. This should be done carefully
by lightly scrubbing with a soft tooth brush or similar.
Place the sensors in the Electrode Cleaner solution ( AS9500) for about 5 minutes to completely
dissolve any trace of inorganic foulants.
Remove and rinse thoroughly in fresh water before replacing it in the manifold. Proceed to
calibration or verification of sensors as outlined in the commissioning section.
