(C) WATER QUALITY REQUIREMENTS
(D) INSTALLATION
DIMENSIONS
The unit should only be operated with water that meets the following minimum criteria:
Turbidity/Suspended Solids: Ideally less than 1 NTU (Nephelometric Turbidity Unit). If the feed water has
ne sediment, a ner pre-lter (1 micron or smaller) may be used. If the water has very high turbidity, a back-washable multi-media lter is
recommended along with a cartridge type lter.
Hardness: Less than 7 GPG (120 mg/L). Hard water causes scale build-up on the quartz sleeves thereby reducing the UV transmittance in the
water and in turn reduced performance.The UV system will work with hard water for a short time after which the scale build-up on the quartz
dome will cause reduced disinfection performance (unsafe condition). It is therefore recommended that, for hard water, a water softener should
be installed prior to the UV system.
Iron & Manganese: Iron less than 0.3 PPM (mg/L) and Manganese less than 0.05 mg/L is desirable. At higher concentrations, a suitable water
conditioner (e.g. an Iron Filter or Greensand lter) should be installed prior to the UV system to prevent iron build-up on the quartz dome that
can cause insucient disinfection.
Tannins and Colour: Water with tannins or colour has low UV transmissivity that reduces UV system performance. The UV system will not work
if the water has tannins or colour. A tannin-removal system should be installed for proper disinfection.
INSTALLATION NOTES AND CAUTIONS:
The Aqua Flo AQUV Water Disinfection System is designed for installation on the cold water line only at the point of entry (POE). The system must
be installed in accordance with all local, state or provincial regulations.
The system requires a constant power supply of 110V AC.
It is strongly recommended to have a dedicated electrical circuit for the UV system. A CSA or equivalent certied surge protector must be installed
to protect the ballast from electrical surges.We recommend surge protector rated for a clamping voltage of less than 400 Volts, response time of
less than one nanosecond, and energy absorption of at least 600 Joules.
The AQUV-8R1 system has been designed for maximum water ow rates of 8 US GPM (30 liters per minute). If higher ow rates exist
occasionally, it is recommended that a ow restricter be installed at the inlet port( 8 US GPM for AQUV-8).
The system should be installed indoors in a protected area where the temperature does not fall below 4°C (40°F).
For optimum performance, the system should be wall-mounted in a vertical position with the lamp connector at the top.
It is highly recommended to install bypass piping with a shut-o valve around the unit. This way you can still have water in case you need to
remove the UV unit for service.
Provide a minimum clearance of 2 feet above the unit for lamp replacement.
Use onlyTeon tape for all connections. Do not use any other sealant on the threads.
NOTICE
Check with your local public works department
for applicable local plumbing and sanitation
codes. Follow local codes if they differ from
the standards used in this manual. Otherwise,
carefully follow the instructions in this manual.
Canature is not liable for any non-compliance
with local requirements
CAUTION!
** Install a pressure regulator and water hammer
arrestor if pressure exceeds maximum rating of
100 psi at any time. Note: If daytime pressure is
over 80 psi, night time pressure may exceed
maximum pressure rating.
