The HPF-UV System is weather resistant, however, where possible it is best for the longevity of the system
to install the unit undercover, if possible, to shield it from direct sunlight and weather extremes such as
rain, storms, and frost.
II. Stainless Steel Enclosure
The Stainless-Steel Enclosure & Frame of the HPF-UV system is proudly Australian Made & Owned.
Manufactured locally here in SE QLD. It features a robust stainless-steel frame & thick heavy duty
mounting plate for the filtration. The front cover is a sleek & stylish brushed chrome finish with premium laser etching
rather than plastic stickers/labelling to blend in with a more modern and upmarket style home. The top cover has a
toughened glass viewing window for easy monitoring of the UV system and the pressure gauges. Durable automotive
grade 3M™ compressed foam tape lining fixed to the joins to reduce metal on metal contact and reduces the chance
of water and dust from entering the top section. Toolless fixing screws are used to mount the front cover and top
cover in place which can easily be removed by hand OR a flat head screwdriver.
III. System Installation & Mounting
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).
Check the rated working pressure for operation recommendations. Install sterilizer equipment in a readily accessible
and well-lit location to facilitate inspection and maintenance. On all units allow sufficient head-space to change the
UV Lamp and Thimble (typically leave a maintenance space equal to the overall UV system length) and other parts.
The system is constructed from Stainless Steel and has two keyhole mounts at the rear of the top plate for mounting
the unit. Allow enough space on either side for the plumbing connections and ensure there is enough space in front of
the unit to allow easy removal of the front/top covers and 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
installation & removal of the top cover.
IV. Installing Connections
The HPF-UV system has a standard 1” Female BSP port for the inlet connection into the stage 1 Big Blue filter housing.
The outlet point 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).
DO NOT use any type of liquid thread sealant as this will cause the cap to split shortly after it cures –
warranty will not cover this.
Thread tape is the only form of sealing material permitted for use on these housings. Alternatively, you can
also use a suitable 1” BSP fitting with an O-ring for sealing.
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.
