• Always disconnect power before performing any work on the disinfection system.
• Regularly inspect your disinfection system to ensure that the power indicators are on and no alarms are present.
• Replace the UV lamp annually (or biannually if seasonal home use) to ensure maximum disinfection.
• Always drain the reactor chamber when closing a seasonal home or leaving the unit in an area subject to freezing tem-

Operating & Maintenance Instructions

Prior to performing any work on the disinfection system, always disconnect the power supply first.

UV Lamp Replacement:

NOTE: RESET LAMP LIFE TIMER AFTER LAMP REPLACEMENT (Page 7). Refer to www.lamprecycle.org for lamp disposal.

To replace the lamp, there is NO need to disconnect the system
from the water supply, nor to drain the water from the reactor cham-
replacement is a quick and simple procedure requiring no special
tools. The UV lamp must be replaced after 9,000 hours of continu-
ous operation (approximately one year) in order to ensure adequate


Disconnect main power source and allow the unit to power down for
30 sec. Remove the lamp connector by rotating the tab of the gland
nut (Figure 2A). Remove connector and lamp from the reactor
chamber. Separate the lamp from the connector (Figure 2B). 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 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.


To install a new lamp, first remove the lamp from its protective pack-
aging, again being careful not to touch the lamp glass itself.
Carefully insert the lamp into the reactor vessel (actually inside the
quartz sleeve) (Figure 2C). 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 (Figure 2B). Lamp is not keyed so it is important
to ensure the lamp wires do not interfere with UV sensor detection as low UV alarms could
result in UVSS-M models. The two wires should be oriented furthest away from the sensor
port. Ensure the connector is fully seated onto the UV lamp (Figure 2D).


Once the lamp is fully seated on the connector, slide the connector over the gland nut. Once
the connector is located fully over the gland nut, rotate the tab back in to lock the connector
in place (Figure 2E).

Quartz Sleeve Replacement / Cleaning:

Mineral deposits and sediment may accumulate on the quartz sleeve decreasing the UV energy
detected. 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 reactor (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” sec-

tion on page 5.

2. Shut off the upstream water supply that feeds water into the reactor chamber.

3. Shut off the downstream water supply. 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
