**These models have dual voltage motors, 120 and 240 volt They are WIRED FOR 120 VOLT but can be convereted to 24
volt operation, instructionsfor connecting the motor for operation at 240 volt can be found printed on the inside of the
motor cover or on the nameplate of the motor.
*A circuit breaker is preferred..Use only a fuse or circuit breaker that is the same rating as the branch circuit the air
compressor is operated on, If the air compressor is connected to a circuit protected by fuses, use dual element time
delay fuses (Buss Fusetron Type "T" only)_
These air compressors can be operated on a 15 amp
circuit if:
1. Voltage supply to circuit is normal.
2. Circuit is not used to supply any other electrical
needs (lights, appliances, etc.)
3. Extension cords comply with specifications in
owners manual.
4. Circuit is equipped with 15 amp circuit breaker or 15
amp Fusetron Type "T" time delay fuse.
If any of the above conditions cannot be met, or if opera-
tion of the compressor repeatedly causes interruptionof
the powerit may be necessary to operate it from a 20 amp
circuit.. It is not necessary to change the cordset if this
change is required.
When converting this model to 240 volt operation, the
attached three-prong 240 volt plug must be replaced
with a three-prong 240 volt plug (purchase locally) or
order line cord Part No, SUDL-404-1.
GLOSSARY
CFM: Cubic feet per minute
SCFM: Standard cubic feet per minute; a unit of mea-
sure of air delivery
PSlG: Pounds per square inch gauge; a unit of measure
of pressure
ASME: American Society of Mechanical Engineers;
made, tested, inspected and registered to meet the stan-
dards of the ASME
U,L, LISTED: Samples of compressor outfits, taken
from production, were submitted to UL and found to
comply with their requirements for design and
performance
Cut-In Pressure: White the motor is off, air tank pres-
sure drops as you continue to use your accessory When
the tank pressure drops to a certain low level the motor
will re-start automatically The low pressure at which the
motor automatically re-starts is called "cut-in pressure"
Cut-Out Pressures: When you turn on your air com-
pressor and it begins to run, air pressure in the air tank
begins to build It builds to a certain high pressure before
the motor automatically shuts off - protecting your air
tank from pressure higher than its capacity The high
pressure at which the motor shuts off is called "cuFout
pressure",
