Maintenance Instructions:
WARNING
• Always disconnect power before performing any work on the disinfection system.
• Always shut-off water flow and release water pressure before servicing.
•
Regularly inspect your disinfection system to ensure that the power indicators are on and no alarms are
present.
•
Replace the UV lamp annually (or biennially if seasonal home use) to ensure maximum disinfection.
•
Always drain the chamber when closing a seasonal home or leaving the unit in an area subject to freezing
temperatures.
UV LAMP REPLACEMENT:
NOTICE
• Reset lamp life timer after lamp replacement. Refer to page 15. Refer to www.lamprecycle.org for UV lamp disposal.
•
Do not use water during replacement of UV lamp.
1. To replace the lamp, there is NO need to disconnect the system from the water supply, nor to drain the water from
the UV chamber.
DO NOT USE WATER DURING THIS PROCEDURE. 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.
Refer to the assembly diagram on page 5.
2.
Unplug the electronic ballast from the electrical outlet and allow the lamp to cool for at least 5 minutes before
removing. Pull out the U clip from the gland nut. Remove bushing, connector and lamp from the UV chamber.
Separate the lamp from the connector. Do not twist the lamp from the connector, simply slide the two apart. Avoid
touching the lamp’s quartz surface. Handling the lamp at the ceramic ends is acceptable, however if you must touch
the lamp quartz, please use gloves or a 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.
3.
To install a new lamp, first remove the lamp from its protective packaging, again being careful not to touch the lamp’s
quartz surface. Oil deposits from your fingers can create hot spots on the surface which may lead to premature
lamp failure. Handle the lamp by the ceramic ends only. If the quartz surface becomes dirty, use a lint-free cloth and
isopropyl alcohol to remove dirt. Carefully insert the lamp into the UV 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. Ensure the connector is fully seated onto the UV lamp.
4. Once the lamp is fully seated on the connector, slide the connector and bushing into the aluminum gland nut. Gently
press down on the bushing and squeeze/slide the U clip through the gland nut’s four upper holes (2 pair, 180° apart).
5.
Plug in ballast to the electrical outlet.

QUARTZ SLEEVE REPLACEMENT / CLEANING:
Mineral deposits and sediment may accumulate on the quartz sleeve decreasing the UV light transmittance and system
performance. Good maintenance of filtration equipment will reduce the accumulation of residues. If necessary, remove the
quartz sleeve and clean with a commercially available scale remover (CLR, Lime-Away, etc.) and a lint free cloth. Repeat
the process as often as necessary to keep the quartz sleeve clean. Be sure to remove all traces of cleaning fluid from the
sleeve before it is reinstalled in the UV chamber (be sure not to allow liquid inside the sleeve).
1.
First remove the UV lamp by following steps 1 & 2 as outlined in the “Lamp Replacement” section above.
2.
Shut off the upstream water supply that feeds water into the UV chamber.
3.
Shut off the downstream water supply. Use the filter housing vent-valve to slowly depressurize. If your system does
not have a separate downstream valve, simply open a downstream faucet to release any pressure that may be built-
up in the system.
