1. Your Disinfection Unit – Pre-Installation

Your Ultraviolet (UV) water disinfection system has been tested at Glasco’s manufacturing facility. The unit has been
hydrostatically pressure-tested to 100 psi. In some cases, a small amount of water may remain in the vessel. In order to
insure that the unit works at optimum performance, please follow the instructions outlined in this manual.

August 2009

1.1. Warning

UV light is harmful to your eyes and skin. Do not look directly into the light. Always unplug (disconnect power) your
unit before installing or removing a lamp. Your unit may have a green LED light that indicates that the lamp is
operating and the unit has an audible alarm that will sound in the event of lamp failure. If the LED goes out, contact
your dealer for service. If your unit has an audible alarm and it goes off, contact your dealer.

Since the unit is run by electricity, please remember to disconnect all power before servicing the equipment. Failure to
do so may result in serious injury or death.

When handling lamps and quartz, use gloves to prevent them from becoming dirty. If they do, wipe them with alcohol.

1.2. Your Water Supply

Glasco recommends that trained professionals test and maintain your water supply. In addition to testing the water to
see if UV is appropriate, we recommend pre-filtering systems (softeners, carbon or reverse osmosis) to help remove
tastes, odors, minerals and cysts.

1.3. UV Effectiveness

Your disinfection unit needs to be maintained. Change your lamp on a yearly basis and insure that the quartz sleeve is
cleaned on a regular basis.

Failure to do periodic maintenance will impact your unit’s effectiveness.

1.4. Flow Rate

Your unit has been designed to accommodate a certain flow rate. In order to work effectively, you may need to install a
flow control device. This device attaches to the inlet and controls the water that enters the system. Note: your system
may have come with a flow controller.

Failure to use a flow control (available at most plumbing supply stores) may reduce the effectiveness of your
disinfection unit.

1.5. Inspection

Insure that lamps and quartz have not been broken. We recommend that you use gloves when handling lamps and
quartz sleeves to prevent them from becoming dirty. Dirt and skin oils will impact the UV output.

A warranty sheet has been included. Please fill out the warranty and send back to manufacturer or dealer. This
warrantees the chamber for 7 years and electrical components for 1-year.

1.6. Electrical Requirements

The electronics have been designed to work with standard power supplies. Since the unit is susceptible to power
fluctuations, we recommend that the system be kept off any lines where there are surges. This includes pumps or
motors. If there are fluctuations, please use a surge suppressor. Systems will come with plugs, which require no “hard
wiring”. Please look at the outside of the electrical “box” for Voltage, Cycle and AMP draw.

1.7. Location of Unit

UV disinfection works best when it is installed closest to point of use. When installing, remember that you will need to
be able to remove lamps and quartz as part of a maintenance schedule. Allow yourself enough room to accomplish
these tasks. Unit can be mounted vertically or horizontally. Inlet and outlet can face up or down.
