**These models have dual voltage motors, !20 and 240 volt. They are WIRED FOR 120 VOLT but can be converted to 240
volt operation. Instructions for 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. Vomtage suppmyto circuit is normat.
2o Circuit is not used to supply any other
electrical needs (lights, appliances, etc°}
3. Extension cords comply with specifica-
tions in owners manual
When converting this model to 240 volt opera=
rice, the attached three-prong 120 vo_t pJug
must be replaced with a three-prong 240 volt
p_ug (purchase locally) or order line cord Part
No, SUDL-4044.
4. Circuit is equipped with 15 amp circuit
breaker or 15 amp Fusetron Type"T" time
demayfuse.
If any of the above conditions cannot be met, or if opera-
tion of the compressor repeatedly causes interruptionof
the power it may be necessary to operate it from a 20
amp circuit. It is not necessary to change the cordset if
this change is required.
GLOSSARY
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of meas-
ure of air delivery.
PSIG: 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: Underwriter Laboratories; Samples of
compressor outfits, taken from production, were sub-
mitted to U.L and found to comply with their require-
ments for design and performance
Cut4n Pressure: While the motor is off, air tank pres-
sure drops as you continua to use your accessory. When
the tank pressure drops to a certain iow level the motor
wif! re-start automatically. The low pressure at which the
motor automatically re-starts is caIled "cut-in pressure,"
Cut-Out Pressure: When you turn on your air compres-
sor 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 pres-
sure at which the motor shuts off is called "cut-out
pressure."
