CONDENSATE DISCHARGE PIPING. If installing a condensate discharge line, the piping must be at least one size larger than the connection, as short and direct as possible, secured tightly and routed to a suitable drain point or waste container. Condensate must be disposed of in accordance with local, state, and federal laws and regulations.

•WARNING If an aftercooler, check valve, block valve, or any other restriction is added to the compressor discharge, install a properly-sized ASME approved safety/relief valve between the compressor discharge and the restriction.

INSTALLING ELECTRICAL WIRING (ELECTRIC MOTOR UNITS) _____________________________________________

•WARNING Electrical installation and service should be performed by a qualified electrician who is familiar with all applicable local, state and federal laws and regulations.

GENERAL. The motor rating, as shown on the motor nameplate, and the power supply must have compatible voltage, phase and hertz characteristics.

WIRE SIZE. The electrical wiring between the power supply and electric motor varies according to motor horsepower and other factors. Install adequately sized power leads to protect against excessive voltage drop during start-up. Refer to the National Electric Code (NEC) for information on selecting the proper wire size and securing electrical connections. If you connect additional electrical equipment to the same circuit, consider the total electrical load when selecting the proper wire size. DO NOT USE UNDERSIZE WIRE.

If wire size information is not available, the wire sizes shown in the following wire selection chart can be used as a safe guide, if the distance does not exceed 50 feet (15.3 m). For longer distances, consult and electrical contractor or the local electric company for recommendations.

MAGNETIC STARTER. If the motor installed on your unit has a motor reset button, it does not require a magnetic starter. If the motor does not have this button and the unit does not have a factory-installed starter, install a magnetic starter with thermal overload protection. Follow the manufacturer’s instructions for installation. Ingersoll-Rand cannot accept responsibility for damages arising from failure to provide adequate motor protection.

FUSES. Refer to the NEC to determine the proper fuse or circuit breaker rating required. When selecting fuses, remember the momentary starting current of an electric motor is greater than its full load current. Time-delay or “slow-blow” fuses are recommended.

PRESSURE SWITCH. On units without a factory-installed pressure switch, wire a pressure switch in accordance with the appropriate wiring schematic in the DIAGRAMS section of this manual. Mount the pressure switch in accordance with the manufacturer’s recommendations. The connecting line to the receiver tank must be as short and direct as possible, and certified safe for at least the maximum working pressure of the unit.

CONNECTING A BATTERY (GASOLINE ENGINE UNITS) __

NOTE

If you will be making connections to a remote

 

battery, the engine on the compressor unit must be

 

equipped with an alternator.

BATTERY. A 12 volt battery with a minimum current rating of 250 CCA (cold cranking amps) and minimum ampere-hour rating of 24 Ah should be sufficient for cranking most electric start engines.

BATTERY CABLES. Refer to the following table for size and length recommendations.
