PROBLEM
SOLUTION
Unit will not turn on
•
Make sure power is running to the system is via a
working outlet
•
Press SELECT (OVERRIDE) on the system. If unit turns
on, then reset clock event settings.
•
If backlight turns on and there is no information on
the LCD display, the LCD is malfunctioning
•
If unit still will not run replacement will be necessary.
Pump does not run
(If unit has a pressure switch)
•
Unplug the DC power plug from the jack on the
SXD2110 control unit, then plug back in
•
If pump stops immediately after restarting there
may be a clog in the pressure line, try again with
tubing disconnected, and check collector nozzle for
obstructions.
•
If pump will not stay on, unit will need to be re-
placed.
•
Unplug phoenix connector from machine
•
If unit still does not work, refer to above
•
If unit runs check fan to see if the fan is running on
the HVAC system
•
If fan is running, ensure pressure switch entry loca-
tion is far enough downstream from duct changes:
reduction, enlargement, turn, split, etc.
•
If both the fan is on and the pressure switch probe
is located in the correct position, check the switch by
blowing into the probe. If the switch “clicks” there
may not be enough airflow in system for activation.
•
If there is no audible “click”, replace switch. Be sure
to not move switch as this can cause a false start.
Cannot smell scent
•
Make sure pump is running and is set to the proper
# of nozzles.
•
Confirm an event is set with timer set for the unit to
run at the current times of the day.
•
Check for oil in the container.
•
Make sure pump is on. Detach 3/8in. Output Tube
from Collector by pressing metal tab on fitting and
pulling strait up to release.
•
If no mist is seen the bottom half of the nozzle or
the pickup tube is clogged, a small strip of wire can
be used to clear obstruction. If that does not work
replacement will be necessary.
•
Make sure 3/8in. Output Tube on the discharge side
of collector is mounted in the correct supply duct and
is clear without any dips or traps.
•
Make sure all dampers are open in the HVAC duct
and the HVAC system fan is on.
