OPERATION & MAINTENANCE INSTRUCTIONS TROUBLESHOOTING GUIDE & WATER CHEMISTRY
• Always disconnect power before performing any work on the
ultraviolet disinfection system.
• Regularly inspect your disinfection system unit to ensure the UV light
is still glowing.
• Replace the UV lamp annually (or biennially if seasonal use) to ensure
a high bacteria and virus kill rate.
• Always drain the UV system when closing a cabin/cottage or leaving
the unit in an area subject to freezing temperatures.
A. UV Lamp Replacement
To replace the lamp, there is NO need to disconnect the system from the water supply,
nor to drain the water from the reactor chamber. Lamp replacement is a quick and
simple procedure requiring no special tools. The UV lamp must be replaced after
9,000 hours of continuous operation (approximately one year) in order to ensure
adequate disinfection.

1. Disconnect main power source and allow the unit to power down. Remove the
lamp connector by sliding the metal retaining ring away from the body of the
connector. Remove the lamp form the reactor chamber. Separate the lamp from
the connector. Do not twist the lamp from the connector, simply slide the two
apart. Avoid touching the lamp on the glass portion. Handling the lamp at the
ceramic ends is acceptable, however if you must touch the lamp glass, please use
gloves, or soft cloth. Fully remove the lamp from the reactor chamber being careful
not to angle the lamp as it is removed from the chamber. If the lamp is removed
on an angle, pressure will be applied on the inside of the quartz sleeve, causing
the sleeve to fracture.
2. To install a new lamp, rst remove the lamp from its protective packaging, again
being careful not to touch the lamp glass itself. Carefully insert the lamp into the
reactor vessel (actually inside the quartz sleeve). Insert the lamp fully into the
chamber leaving about two inches of the lamp protruding from the chamber.
Next, attach the connector to the UV lamp. The connector is “keyed” and will only
allow correct installation in one position. Ensure the connector is fully seated onto
the UV lamp.
3. Once the lamp is fully seated on the connector, slide the connector over the
aluminum retaining nut. Make sure the metal retaining ring on the connector is
pulled away from the body of the connector in order that the connector may slide
fully over the retaining nut. Once the connector is located fully over the retaining
nut, slide the metal ring back into lock the connector in place. As this connector
is keyed to the reactor chamber, make sure the depression on the connector
is located over the ground lug located on the reactor chamber.

Water quality is extremely important for the optimum performance of your UV system.
The following levels are recommended for installation:
• Iron:<0.3 ppm (0.3 mg/L)
• Hardness *:< 7 gpg (120 mg/L)
• Turbidity: < 1 NTU
• Manganese: < 0.05 ppm (0.05 mg/L)
• Tannins: < 0.1 ppm (0.1 mg/L)
• UV Transmittance: > 75%
(Call factory for recommendations on applications where UVT < 75%)
* Where total hardness is less than 7 gpg, the UV unit should operate eciently provided the quartz sleeve is cleaned
periodically. If total hardness is over 7 gpg, the water should be softened.
If your water chemistry contains levels in excess of those mentioned above, proper
pre-treatment is recommended to correct these water problems prior to the installation
of your UV disinfection system. These water quality parameters can be tested by your local
dealer, or by most private analytical laboratories. Proper pre-treatment is essential for the UV
disinfection system to operate as intended.
