Installation Guidelines
Please refer to this section for typical installation guidelines, typical layout and Housing Installation
diagrams.
Before you start
Select a suitable location for installation - preferably in close proximity to the main system, protected
from the public and environmental factors such as direct sunlight. The suitable location must not
be on top of a source producing large amounts of heat (e.g. metal fence or shed) and ideally not
be in direct sunlight. The Ultima LCD screen must be covered by the flap lid for UV protection on
all outdoor installation. A wall area of approx. 0.75 m. wide by 1.0 m. high is ideal for mounting
your controller. Mount the unit at eye-level to allow good navigation of the controller. A minimum
floor area of approx. 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 environmental elements when installing. 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 chemicals will damage materials used in construction of
buildings, particularly roofing. Never assume that the equipment will not leak, under certain
conditions that will occur. It is the responsibility of the installer to ensure that such events do not
create damage that should have been 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 in line to supply sample water to the system,
• Minimum 12 litres/minute supply flow 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).
Users of the Ultima are prevented from contact with hazardous voltages by the protection cover
(Picture 1 and Picture 2). Only a certified electrician or Aquarius Approved Service Technician may
remove the protection cover to access the hazardous voltage area. It is required to disconnect the
controller from the supply before removing the cover or performing any electrical work, including
unplugging and/or replacing all circuit boards.
