Ingersoll-Rand 2000 Installing Electrical Wiring Electric Motor Units, Compressor Lubrication

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.

aWARNING	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)

aWARNING	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.

MOTOR			THREE
HP			PHASE
	200V	230V		460V	575V
20	3	4		8	10
25	1	2		6	8
30	0	1		6	8

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.

COMPRESSOR LUBRICATION

aCAUTION	Do not operate without lubricant or with
	inadequate lubricant. Ingersoll-Rand is not
	responsible for compressor failure caused by
	inadequate lubrication.

SYNTHETIC COMPRESSOR LUBRICANT. Ingersoll-Rand recommends All-Season Select® synthetic lubricant from start-up.

ALTERNATE LUBRICANTS. You may use XL-300 or a comparable petroleum-based lubricant that is premium quality, does not contain detergents, contains only anti-rust, anti-oxidation, and anti-foam agents as additives, has a flashpoint of 440°F (227°C) or higher, and has an auto-ignition point of 650°F (343°C) or higher.

See the petroleum lubricant viscosity table below. The table is intended as a general guide only. Heavy duty operating conditions require heavier viscosities. Refer specific operating conditions to Ingersoll-Rand for recommendations.

Temperature Around		Viscosity @ 100°F		Viscosity Grade
Compressor			(37.8°C)
°F	°C	SUS	Centistokes	ISO	SAE
< 40	< 4.4	150	32	32	10
40-80	4.4-26.7	500	110	100	30
80-125	26.7-51.0	750	165	150	40

*= For Models 2000 and 2000P, use Ingersoll-Rand XL-740HT Compressor Oil in temperatures above 100°F (37.7°C).

If you use a petroleum-based compressor lubricant at start-up and decide to convert to All-Season Select® later on, the pump must be decarbonized and flushed before conversion. Contact Ingersoll-Rand for more information.

FILLING PROCEDURES:

1.Unscrew and remove the oil fill plug.

2.Fill the crankcase with lubricant.

3.Replace the oil fill plug HAND TIGHT ONLY.

aCAUTION	Do not remove the oil fill plug while the
	compressor is running.

Refer to the following table for crankcase capacity.

Model	Crankcase Capacity
2000, 2000P	176 oz. (5205 ml.)

Use one of the following methods illustrated to determine when the crankcase is full.

B

A = FULL level

B = ADD level
