(B) SAFETY GUIDELINES
(CONTINUED)
To avoid
possible electric shock, extra care should be taken since water may be present near electrical equipment. Unless specifically referred to
in these instructions, do not attempt repairs yourself. Do not plug the unit in if any electrical surfaces or electrical parts are wet.
DO NOT LOOK DIRECTLY AT UV LAMP WHEN LAMP IS ON
. UV light can cause serious burns to eyes and skin.
Do not
operate the UV lamp outside the UV disinfection chamber.
Do not
use this unit for any purpose other than its intended use for potable water disinfection. The use of attachments not recommended,
approved or sold by the manufacturer may result in improper performance of the unit or an unsafe condition and void the product warranty.
Do not
operate the system if it has a damaged electrical cord or plug, is malfunctioning, or has been damaged in any way.
Do not
touch the lamp or quartz dome with dirty or moist hands. Hold the lamp and dome by the ends with soft dry gloves or cloth.
Before any cleaning or maintenance on the system, always unplug the unit from the power source.
Disconnect power cable from the power outlet by holding the plug. Never pull the cord.
To comply with the National Electrical Code and to provide additional protection from the risk of electric shock, this system should only be
connected to a properly grounded, grounding-type controller receptacle that is protected by a Ground Fault Circuit Interrupter (GFCI).
Ensure that the lamp connector ground wire is connected to the grounding stud on the chamber.
Installation of the UV disinfection system and water filter will interrupt electrical grounding continuity of your plumbing system. For directions
on restoring the electrical grounding continuity, consult a certified electrician
Protect your unit from freezing and weather elements.
WARNING
To ensure continuous protection,
UV LAMP MUST BE
REPLACED ANNUALLY
. After 1 year of use, it will no
longer provide effective disinfection even though it stays lit.
WARNING
USE ONLY
GENUINE
AQUA FLO AQUV LAMPS. Use of non-
Aqua Flo AQUV UV lamps can result in unsafe drinking water,
which may lead to illness and/or death, ballast failure or fire,
and will void your product warranty. (see page 12 for details)

risks associated with the product within this manual but cannot disclose risks that are beyond its
knowledge.
(C) WATER QUALITY REQUIREMENTS
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). A 5 micron sediment filter or
better must be installed in the UV system at all times. If the feed water has fine sediment, a finer pre-filter (1 micron or smaller) may be
used. If the water has very high turbidity, a back-washable multi-media filter is recommended along with a cartridge type filter.
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 filter) should be installed prior to the UV system to prevent iron build-up on the quartz dome that
can cause insufficient 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.
