monitoring, please skip to next step.
The Photronic Series incorporates an audible and
visual annual service reminder indicator. A lamp status
monitor on the cover provides a visual LED signal
(solid GREEN) when the unit is operating correctly.
Other situations are covered on the chart on page 7.
(See UV lamp monitor chart- see page 7)

2. Remove the cover from the unit.
3. Press down and hold the square yellow RESET
button (hold down for 10 sec.) on circuit board (located
adjacent to the LED on the circuit board), the LED
should turn GREEN while the button is depressed.
4. Release the square yellow RESET button.

UV Lamp replacement:
NOTE: When replacing lamps after 1 year or 2 years of
operation disconnect power to the unit first.
After the lamps are in place, complete steps 1-5 to set
the service indicator to 0.
For optimum 24/7 air stream disinfection it is
recommend the UV-C lamp is replaced on an
annual basis.
Application with a Humidifier:
The Media Air Cleaner is compatible with humidifiers.
Avoid applications where water mist will reach the pleated
media filter.
When an evaporative type humidifier is used, it may be
installed between the furnace warm air duct and the return
air duct without affecting the air cleaner.
Atomizing and spray type humidifiers should be installed
with at least 6 feet between the Air cleaner and humidifier.
Air Conditioning:
The air cleaner should be installed upstream of the cooling
coil. This will keep the coil clean and reduce air
conditioning coil maintenance. Improved cooling efficiency
is the result, which directly affects energy costs. A clean
coil will reduce utility costs.
Failure to replace media can cause damage to the cooling
system.
