COMMISSIONED HELO FIXTURES
Commissioning
Helo fixtures come pre-commissioned but if commissioning adjustments are needed in the future, please
contact your PURO Lighting representative for assistance.
OPERATIONAL MODES FOR COMMISSIONED FIXTURES
Fixtures ordered for commissioning have three primary modes available to users. Fixtures must be
programmed before initial use.
Autonomous Mode: In this mode, once plugged in, the fixtures will automatically activate once the space is
unoccupied and continue disinfection on a regular schedule, adjusting frequency based on level of activity
in the space based on the motion sensor. Users may select the timeout time, which determines how long
the fixture will wait until resuming operation after motion is detected.
Scheduled Mode: In this mode, the fixture will activate at the selected time(s) of day during each 24-hour
period. Users may schedule up to 8 start times each day to operate for a specified run time (i.e. 30, 60, 90,
or 120 minutes). Users may select the motion timeout, which determines how long the fixture will wait
until resuming operation after motion is detected. The fixture may also be configured to activate a disin-
fection cycle immediately when it is powered and then continue with the scheduled operational time(s).
Single Cycle Mode: In this method, users will manually activate the fixture to start a disinfection cycle. The
fixture will then run its pre-programmed cycle (i.e. 10, 15, 20, 25 or 30 minutes) one time before entering
safe mode until power is cycled on and off again. Users may select the timeout time, which determines
how long the fixture will wait until resuming operation after motion is detected.
GENERAL OPERATION OF COMMISSIONED HELO FIXTURES
1. The PURO Lighting Helo F1 and F2 fixtures are designed to be installed approximately 2 meters (~6 1/2
feet) away from priority areas. See page 12 for additional information on installation methods. Helo fixtures
have been tested to kill E. coli, S. enterica, and S. auereus at distances of up to 4 meters (~13 feet) away, but
the length of time necessary to run the fixture increases proportionately to the distance from targeted
area. Reflective surfaces, including standard glass, will enhance the effectiveness of the fixture as the UV
light will reflect off of these surfaces.
2. The fixtures operate at 120V AC at 60 Hz. Once powered on, the fixtures will draw up to peak current for 4
second intervals (3.5 amps for Helo F1 and 7 amps for Helo F2). Ensure the breaker has available amperage
during operation.
3. The space should be unoccupied during cleaning cycles. Exit the space within 60 seconds for optimal
functioning of the fixture.
4. The fixtures’ redundant safety systems will stop the fixture from operating if motion is detected in the
space. The fixtures will resume operation approximately 60 seconds (unless alternate motion timeout was
selected) after room is unoccupied and no additional motion is detected.
5. The fixtures will run a safety test to ensure proper functioning and that there is no motion detected in
the space. If successful, fixtures will run their pre-programmed operational cycle. See guidelines for more
information on operational modes.
6. Allow the fixtures to complete its entire cycle before unplugging or turning off power to the fixture. This
allows the fixtures to enter safe mode. If necessary to cease operation prior to completion of cleaning cycle,
be sure to keep fixture away from water for optimal safety.
*It is recommended that after every 30-minute run that you allow the unit to cool down for a 15-minute
period of time, in order to maximize the life expectancy of your PURO Lighting Helo Fixture.
