II. System Installation
NOTE: All units are quality tested from the factory. When you receive your system, open package to check all
components are inside (Reactor Chamber, UV Lamp, Thimble (Quartz Tube), O-ring, Electronic Ballast and Support).
All units are rated up to 12bar. Check the rated working pressure for operation recommendations. Mount your
Ultraviolet Sterilizer horizontally or vertically on a level and firm surface. Do not lay the system on the ground or
where water may puddle. Do not submerge. Install sterilizer equipment in a readily accessible and well-lit location to
facilitate inspection and maintenance. On all units allow space to change the UV Lamp and Thimble (typically leave a
maintenance space equal to the overall UV system length) and other parts.
III. Mounting
Mount the UV system using the mounting brackets supplied. The system is best mounted with the power lead having
access from the top. Allow enough space on either side for the plumbing connections and ensure there is enough
space in front of the unit to allow easy access for maintenance. Also allow at least 500mm height clearance for the UV
lamp installation & maintenance. The mounting location will require a 10A GPO within ~1.5m from the left side of the
system for the UV power supply. If mounting on an uneven surface (such as rough brick), it is recommended to install
a spacer behind the mounting holes, so the unit is sitting slightly off the wall to allow easier access.
IV. Installing Connections
The outlet point is from the UV system has an internal and external thread to choose from depending on the
installation requirements (i.e. 1” BSP male or ¾” BSP female).
V. Filter Protection
If there is no Pressure Limiting Device (PLV) installed on the main line incoming to the house to limit the
water pressure to 500 kPa, you will need to install one prior to the UV and any pre-installed filtration
system to reduce the pressure in compliance with Australian Plumbing Codes & HPF Warranty. Failure to do
so may cause excessive pressure & potentially damage the system.
It is recommended that an anti-water hammer device is installed on the house to dampen water hammer commonly
caused by washing machines. It is best to install these devices at the point of hammer such as on the cold-water line
at the washing machine or dishwasher.
