**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."
