Sterilite Point-of-Use Drinking Water System - Manual (Page 7)

PLEASE NOTE THE FOLLOWING
1. The Sterilight unit is NOT designed to operate with hot water.
Run only cool tap water through the unit.
2. The ultraviolet lamp in the unit has a useful life of 10,000 on-off cycles
or more. One cycle could be a small cup of water or a large pitcher.
To maximize the life of the lamp, it is best to get a pitcher to store in
the refrigerator for drinking during the day, as opposed to running it
several times to draw individual glasses of water.
3. Depending on the model, your Sterilight ultraviolet lamp may stay
illuminated for approximately 30 seconds after flow through the unit
has ceased. This is normal and is not cause for concern.
REPLACING THE FILTER
The filter element in the Sterilight unit is a high-performance,
multi-layer extruded design. The element has been specifically designed
to complement the patented ozone/UV photo-oxidation process.
Replacement filters can be obtained through
your Sterilight dealer.
The unit MUST NOT be operated without a
filter element except when sanitizing (page 8).
Replace the filter whenever:
1. The filter has been in service six or more months.
2. 1900 or more liters of water (500 gallons) have been
processed by the unit.
3. The filter shows signs of dirt build-up or deterioration, evidenced by
a decrease in the rate of water flow, or a decrease in the swirling
bubble action.
It is EXTREMELY IMPORTANT that the unit be unplugged. The
Sterilight unit contains a high intensity ultraviolet lamp that can
damage tissues in the eye. The UV wavelengths cannot travel through
the plastic housing. However, removing the filter requires that the
cap be removed, exposing the lamp. DO NOT PROCEED WITHOUT
UNPLUGGING THE UNIT!
The Sterilight unit uses state-of-the-art Speed Fit® fittings. They rely
on a lock ring to hold the tubing in place. To remove tubing from the
fitting, hold the lock ring against the fitting while pulling on the tubing.
While it is possible to do this with your fingers, included with your
Sterilight unit is a tubing disconnect tool to make removing the fittings
easier (Figure 12).
