MAINTENANCE
CHANGING THE OZONE LAMP
The Portable Purifier Ozone producing lamp has a life expectancy of ap-
proximately two years, however, fluctuations in local line voltage may reduce
the lamp’s life. When the red indicator light stays on, it is time to change
the lamp.
To maintain optimal performance, DEL recommends replacing
the lamp once a year.
1. Disconnect power before servicing unit.
2. Remove the Portable Purifier from its support if access is limited.
3. Remove the cover from the Portable Purifier enclosure (it is held by
two Philips head screws on the bottom). Be careful not to put strain
on wires connecting cover components.
4.Separate the finned aluminum lamp cartridge from its mounting bracket.
It may require the use of a screwdriver to pry the unit loose as these
clamps are specifically designed to hold the cartridge securely in
place.
5.Separate the electrical connector from the end of the lamp cartridge
by rocking the connector back and forth while pulling it in an outward
direction.
6.Remove the compression nut, washer and rubber seal from the
lamp cartridge by turning the compression nut in a counter-clock
wise direction (should be hand-tight).
7.Remove the old lamp by sliding it out of the aluminum cartridge.
8.Reverse this procedure to intall the new lamp. Be sure the lamp is
fully seated and straight inside the cartridge.
