DO NOT LOOK INTO THE ENGINE DISCHARGE (EXHAUST) TUBE.
DO NOT FOG INTO THE WIND.
DO NOT LEAVE THE FOG CONTINUOUSLY DIRECTED AT THE SAME
AREA OR OBJECT. THIS MAY CAUSE A BUILD-UP OF A FLAMMABLE
SUBSTANCE OR LEAVE UNDESIRABLE DEPOSITS ON WALLS,
FURNITURE, ETC.
NOTE
The formulation flow to the INJECTION ORIFICE is controlled by both a fixed
flow restrictor orifice (or optional formulation metering valve) which controls the
formulation flow rate and an ON/OFF Valve. The fixed orifices supplied with your
machine are:
ORIFICE GPH LPH
#24 1.5 5.7
#36 4.6
#60 8 30.0
#72
*The #72 orifice is installed in your machine and is tested at the factory for
proper flow.
WARNING
THE LARGER NUMBERED ORIFICES PRODUCE HIGHER FLOW RATES.
THEREFORE, THE FOG OUTPUT OF THE LOWER NUMBERED ORIFICES
(#24, #28 and #36) WILL ALL TEND TO PRODUCE A “DRY” FOG. FOG
QUALITY CHANGES FROM “DRY” TO “WET” AS FLOW RATE INCREASE.
THE POINT OF CHANGE OVER FROM DRY TO WET DEPENDS ON
VARIABLES SUCH AS THE FORMULATION TANK PRESSURE,
FORMULATION VISCOSITY, THE STATE OF CLEANLINESS OF THE
FORMULATION SYSTEM AND THE OPERATING CHARACTERISTICS OF
THE ENGINE.
