– Periodic Maintenance
The WCS 2.0 incorporates an elapsed operating hour meter. When this meter reached 9500
(approximately 13 months of elapsed operation), the MAINTENANCE indicator will illuminate.
The WCS 2.0 will continue to operate effectively for up to 500 hours following this indication,
but it is recommended that the UV lamp and filter be replaced as soon as is practical after the
MAINTENANCE indicator illuminates. Once these items have been replaced, the
maintenance alert should be reset using an internal RESET button.

Quartz Tube Installation or Replacement
The Ultraviolet (UV) chamber consists of the outer chamber in which a quartz tube is suspended.
The UV lamp is, in turn, suspended inside the quartz tube. Water circulated through the UV
chamber outside the quartz tube is exposed to UV light radiating through the tube. To prevent
breakage, the UV lamp and quartz tube are not installed in the UV chamber during shipment.
WARNING:
Disconnect power to the WCS 2.0 before changing the UV lamp or
quartz tube and follow the lamp replacement instructions. Exposure to UV light is
hazardous to exposed skin and eyesight.
1. Turn the WCS 2.0 power OFF and disconnect the 12V power pack from the rear
panel of the WCS 2.0 unit. Disconnect the two circulation hoses from the side of the
WCS 2.0.
2. Remove the 6 screws securing the cover at the rear of the WCS 2.0 and the 3 screws
securing the cover at the front of the WCS 2.0.
