CAUTION
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent,
or similarly qualified person in order to avoid a hazard.
• Unplug the appliance before filling or cleaning.
• Maximum water pressure: 73 PSI (.5 mpa).
WATER CONNECTION
Place the unit on a level surface, such as a
benchtop or oor.
If your environment has lile to no venlaon,
place the unit in a central locaon. In a venlated
area, place unit near the intake end. When the
unit is in the desired locaon, connect a water
supply to the female 6mm inlet. Opons:
• Plumb directly to a water supply
(6mm plastic tubing is preferred).
• Connect to a garden hose fitting.
• Plumb to a storage tank higher than the
fogging unit (gravity feed).
POWER CONNECTION
Plug the unit directly into an electrical outlet
and listen for a smooth, quiet operaon. Motor
sha should be centered and vercal. Make any
necessary adjustments. Aer evaluaon, connect
the unit to desired control device:
• Plug into a sensor for best automatic
control.
• Plug into a timer for specific automatic
control intervals.
• Plug directly to an electrical supply for
manual operation.
OPERATION
*WARNING: Designed for atomizing
water only! Do not use ammable, toxic
or corrosive liquids.
• Use the fogging head for directional
fogging output and a drier fog.
• For maximum fogging and circulation,
remove lower housing, upper housing,
and fogging head. Fog will propel 4–5 feet
above the unit.
TROUBLESHOOTING
NO FOG: Check for motor rotaon. If motor
is operang properly, check for an adequate
amount of water in the pan (¼" to 1¼"). If the
pan runs dry, the oat valve may be scking in
the Up posion. If so, the inlet water pressure
needs to be reduced. If water supply is adequate,
check the tapered pump for internal calcium
build-up. Remove, inspect, and clean as needed.
OVERFLOWING PAN: An overlled pan can
cause poor quality fog and wetness around the
unit. A leaky oat valve or a oat that has lled
with water may be the problem.
To check the oat, raise it out of the water and
visually inspect it. No water should be inside and
it should not sink. If OK, then check for leaky
valve. Turn water o and remove the fogger from
the pan. Empty the pan and towel dry. Hold the
oat in the Up posion and turn on the water. If
any water enters the pan while the oat is in the
Up posion, the oat valve needs to be replaced.
MAINTENANCE
Regularly clean the reservoir pan assembly with
soap and water to remove dirt and sediment.
If algae is present, sterilize aected parts with
liquid bleach aer cleaning.
Periodically remove strainer screen and
thoroughly ush. Check to make sure the tapered
pump/fan blade assembly is free of debris.
Once every three months, check unit for
calcium buildup. If buildup deposits are present,
disconnect the water and take the unit outside.
Pour calcium-dissolving solvent (available in local
hardware stores) in pan and operate unit outside
to soen and remove the deposits.
About once a year, remove the housing to check
the SST atomizing screen to be sure the slots are
clear of mineral buildup. To clean, scrub with a
calcium-dissolving solvent.
