* Maximum permissible water pressure in Pascal : 0.5 MPa
** Caution **
• If the power cord is damaged, it must be replaced by the
manufacturer, a service agent or similarly qualified person
in order to avoid a hazard
• Unplug device during cleaning
Water Connection
Place the unit on a level surface, such as a bench top or the floor.
In an environment with little or no ventilation, place the unit in a
central location. In a ventilated area, place unit near the intake end.
When the unit is in the desired location, connect a water supply to the
female ¼” NPT inlet.
See options as follows:
• Plumb directly to a water supply ( ¼” plastic tubing is preferred)
• Connect to a garden hose with additional fittings (sold separately)
• Plumb to a storage tank higher than the fogging unit (gravity feed)
Power Connection
Plug the unit directly into an electrical outlet for evaluation. Listen for a
smooth, quiet operation. Motor shaft should be centered and vertical.
Make any necessary adjustments. After evaluation, connect the HR-50 to
the desired control device. Options listed below:
• Plug into a humidistat for 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! Don’t use flammable, toxic
or corrosive liquids.
•Operating the unit using the fogging head will provide directional
fogging output and a drier fog
• For maximum fogging and circulation, operate unit without the fogging
head - Fog will propel 4 to 5 feet above the unit
Troubleshooting
No Fog
Check for motor rotation. If motor is operating properly, check for an
adequate amount of water in the pan ( ¼” to 1¼”). If the pan runs dry, the
float valve may be sticking in the up position. 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 overfilled pan can cause poor quality fog and wetness around the unit.
A leaky float valve or a float that has filled with water may be the problem.
To check the float, 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 a leaky valve.
Turn water off and remove the fogger from the pan. Empty the pan and
towel dry. Hold the float in the up position and turn on the water. If any
water enters the pan while the float is in the up position, the float valve
needs to be replaced.
Maintenance
• Regularly clean the Reservoir Pan Assembly with soap and water to
remove dirt and sediment. Use liquid bleach after cleaning to sterilize
any parts if algae was present.
• Periodically remove Strainer Screen and thoroughly flush. Also check
to make sure the tapered Pump/Fan Blade assembly is free of debris.
• Once every three months, check unit for calcium build-up. If build-up
deposits are present, disconnect the water and take the unit outside.
Pour calcium dissolving solvent (available in local hardware stores) in
the pan and operate unit outside to soften 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 build-up. To clean,
scrub with a calcium dissolving solvent.
