Sterilite Point-of-Use Drinking Water System owner manual Disconnect unit from power source

For the filter to be removed, the filter element must be saturated with water and all internal seals must be wet. DO NOT ATTEMPT TO REMOVE A FILTER ELEMENT THAT IS NOT WET. Doing so may result in breakage of the glass sleeve or lamp, and could result in personal injury.

1.Disconnect unit from power source.

2.Run water through the unit to insure that the filter is saturated and all seals are wet.

3.Remove the unit from its wall mount (if wall mounted)

4.Grasp the unit firmly and unscrew the cap by turning counterclockwise (Figure 13).

5.Once the cap is completely unscrewed, use the tubing disconnect tool to disconnect the outlet tube (Figure 14).

6.With the outlet tube disconnected, lift the cap and filter out of the unit. It is not unusual for the O-ring at the bottom of the filter to stay on the glass sleeve (Figure 15).

7.Reach in and remove the lower filter O-ring seal as shown (Figure 16).

8.Sanitize the unit prior to installing the new filter. To do this, reinstall the cap (without the filter installed), reconnect the diverter outlet tubing and replace the unit on its mount or stand. Reconnect power and run water through the unit for approximately 5 minutes. Without a filter cartridge in the unit, some ozone remains in the outlet water, sanitizing the upper portion of the unit and the outlet lines.

DO NOT DRINK water that has been run through the unit without a filter.

9.Disconnect power and remove the cap as in steps 3, 4 and 5 above.

10.To insure that the lower filter seal will slide easily into the unit, wet the glass sleeve (Figure 17).

11.The upper (large) seal fits into the top
