Maintenance/12-Month Service Interval
Every twelve (12) months, the filters and UV lamp should be changed. Units in dusty or high use locations may need more
frequent servicing. A machine with the hot water option may require removing any Calcium build-up inside the hot tank,
depending on local water conditions and the type of water treatment
.
NOTE A full RO storage tank must be available for flushing steps.
CAUTION! The machine should not be exposed to direct sunlight, heat sources, or an ambient
air temperature above 90°F (32°C) or below 37°F (3°C).
Do not clean this appliance with a water jet.
NOTE You must use latex gloves when handling the filters, UV bulb, quartz sleeve or any components that
have contact with the drinking water.
Prepare the Unit for Sanitizing
1. Turn OFF the water supply. Activate the dispense button to relieve any pressure in the unit.
2. Turn OFF the red switch at the rear of the unit and unplug the power cord.

4. Remove and dispose of all old filters from the unit.
5. Open the top cover and remove the UV lamp.
6. Unscrew the UV retaining nut and remove the Quartz Sleeve by pulling straight up. Clean the Quartz Sleeve
with isopropyl rubbing alcohol and remove any surface lime scale that may have adhered to the sleeve sur-
face. Check and replace the black O ring if necessary.
7. Replace quartz sleeve if etched, cracked or unable to be cleaned.
8. Reinstall the Quartz Sleeve and retighten the UV retaining nut. Tighten about ¼ turn after the gasket makes
contact.

zation procedure is complete.
CAUTION! Do not touch the UV lamp or the Quartz sleeve with bare hands.
10. On units using RO, disconnect the storage tank from the product line tee and plug the tubing tee with a ¼”
stem plug (01001142). Sanitize the storage tank separately.
