SAFETY INSTRUCTIONS
In order to protect end users and operators from injury, safety precautions must be followed.This
Installation, Operation and Maintenance (IOM) Manual outlines important safety issues.
1) INFORMATION
Please read this manual prior to installing, starting up, and operating the equipment. The equipment
uses the latest in UV technology, and has been designed to make operation and maintenance easy.
The quality of the liquid entering the UV system needs to be monitored. Based on water quality, the
UV system will need to be cleaned on a periodic basis. Maintenance of the UV system will require
replacement parts. It is suggested that key spare and replacement parts be kept on hand. For best
operation, always use manufacturer recommended replacement parts. Other replacement parts
could result in damage to the system and void the warranty.
2) ABOUT ULTRAVIOLET (UV) DISINFECTION
The technology uses UV light to target and disable disease-causing microorganisms and pathogens.
Over 100 years ago, scientists discovered that if you exposed pathogens to UV light, their
reproduction was limited. The UV light source they used resided in the UVC range of the light
spectrum. Specifically, they discovered that light in the 254 nanometer (NM) range was the most
effective wavelength for this process.
When many pathogens are exposed to UV light, their cells become damaged and this damage
inhibits reproduction.The UV light, produced by a special UV lamp, damages the cells’ DNA and
RNA and once damaged, they are unable to replicate. This physical process renders them harmless.
The amount of damage is a result of the intensity of the UVC output multiplied by the time the
pathogens are exposed to the light. The applied dosage is commonly referred to as microwatts or
millijoules and is often expressed as μWs/cm² or mJ/cm². Most industrial applications require a UV
dosage of 30,000 μWs/cm² or 30 mJ/cm².
Why are plants and operators selecting UV technology?
a) UV is considered a green technology
b) No chemicals are added, so there is no need for chemical removal
c) No chemical storage
d) UV works instantly without requiring a residence time
e) Easy maintenance

4) PREPARATION FOR INSTALLING UV SYSTEM
a) Water Quality
For optimum performance of the UV system, water quality is extremely important. Proper
pretreatment is essential for the UV system to operate as intended.
UV disinfection dosages are dependent upon the quality and clarity of the incoming water.
Impurities in the water can interfere with the UV intensity and cause the dosage to fall to unsafe
levels. Have the water tested to determine that it meets the standards in Table 1. If any of the
elements exceed the maximum levels shown in Table 1, contact your water professional for
recommendations for proper pretreatment.
The following Table 1 shows levels that are recommended for installation:
Table 1 — Recommended Water Standards for Installation
Element
Recommended
Maximum Levels
(1mg/L=1ppm)
Actual Value
Turbidity <5 NTU
Suspended Solids <5 mg/l
Color None
Iron 0.3 mg/l
Manganese 0.05 mg/l
pH 6.5 to 9.5
Hardness <120 ppm
b) Important Safety Information
Read and follow all safety precautions to guard against injury. Basic safety precautions must be
observed. Keep on hand for future reference.
UV lamps and their quartz sleeves can become razor sharp if broken. Take care when installing
and removing quartz sleeves. Only hand-tighten compression fittings. Do not use wrenches or
other tools.
CAUTIONS:
• UV light is extremely harmful to eyes and skin and will cause burns.
• Do not look directly or indirectly at the UV light.
• Do not expose your skin for any prolonged time.
• Use protective clothing and eyewear (make sure it is UV resistant) when servicing equipment.
• If accidentally exposed to UV light for an extended period, immediately seek medical
attention.
• Symptoms for eye exposure include burning, itching, and redness. Symptoms for skin exposure
are similar to sun burn.
• Use cotton gloves when handling lamps and quartz sleeves. Skin oils will adhere to the lamps
and quartz sleeves and prevent UV light from properly emanating. If the sleeves become
dirty, wipe them with a lint free cloth with denatured alcohol.

c) Optimizing System Performance
The UV lamps and their corresponding quartz sleeves need to be maintained. As a general rule,
the lamps need to be changed after a year of usage (10,000 hours). Quartz sleeves should be
changed about every three (3) years or sooner if degraded and/or damaged.
Quartz sleeves also need to be cleaned on a periodic basis based on real world operating
conditions. The manufacturer recommends using denatured alcohol or a commercially available
non-abrasive cleaning product. It is important that the cleaning product used leaves no residue.
Always remember to wear gloves when handling lamps and sleeves.
d) Environmental Issues Relating to UV Lamps
UV lamps need to be recycled like fluorescent lamps because they contain mercury. Please
follow your local recycling laws. Visit www.lamprecycle.org for help finding a recycling center
in your area. In the event that you are unable to find a disposal location, contact your
manufacturer’s representative.
e) Receiving UV Equipment and Spare Parts
Inspection of the UV equipment must be made immediately upon receipt for damage and
verification of contents. It is important to compare the contents of your shipment to the actual
packing list. Any deviations must be brought to the supplier’s attention. Additionally, lamps
and quartz sleeves need to be inspected for damage. If shipment or parts are damaged,
immediately contact the supplier and hold broken contents and their containers for inspection
by the shipping company. Failure to make a damage claim within two (2) business days of
receipt of product can result in loss of claim.
f) Electrical Configuration and Maintenance
The UV disinfection system uses sophisticated electronics and specialty lamps. The UV system’s
electronics require clean power. The system has been designed to use a certain specified
voltage. UV equipment must be protected from surges. If the location of the UV system is
susceptible to brownouts, contact your manufacturer’s representative.
Do not exceed three ON/OFF cycles per 24-hour operation. Excessive cycling of the UV system
will cause the UV lamps to age prematurely.
