For maintaining the receiver tank or system air pressure within predetermined limits, the compressor may be operated with automatic start & stop control or constant speed control regulation. The type of regulation used depends upon the application.
ADDITIONALREFERENCES
Unless otherwise stated, dimensions, weights and measurements are provided in standard U.S. measure followed in parentheses by the metric conversion. Any torque values given are stated in inch or foot pounds followed by the Newton-meter equivalent in parentheses. Electrical characteristics are given in voltage-phase-hertz.
RECEIPT & INSPECTION
Ensure adequate lifting equipment is available for unloading and moving the unit to the installation site.
NOTE | Lifting equipment must be properly rated for the |
| weight of the unit. |
aCAUTION | Lift the unit by the shipping skid only. Do not use |
| the motor lifting eye to lift the entire unit. The |
| motor lifting eye is for removing the motor from |
| the unit only. |
aCAUTION! | Do not work on or walk under the unit while it |
| is suspended. |
Use suitable lifting equipment (i.e. forklift) to lift and transport the unit to the installation site. Ensure the lifting equipment, straps, etc. are capable of supporting the weight of the unit.
Before signing the delivery receipt, inspect for damage and missing parts. If damage or missing parts are apparent, make the appropriate notation on the delivery receipt, then sign the receipt. Immediately contact the carrier for an inspection.
All material must be held in the receiving location for the carrier’s inspection.
Delivery receipts that have been signed without a notation of damage or missing parts are considered to be delivered “clear.” Subsequent claims are then considered to be concealed damage claims. Settle damage claims directly with the transportation company.
If you discover damage after receiving the unit (concealed damage), the carrier must be notified within 15 days of receipt and an inspection must be requested by telephone with confirmation in writing. On concealed damage claims, the burden of establishing that the unit was damaged in transit reverts back to the claimant.
Read the unit nameplate to verify it is the model ordered, and read the motor nameplate to verify it is compatible with your electrical conditions. Make sure electrical enclosures and components are appropriate for the installation environment.
INSTALLATION
SELECTINGALOCATION
ELECTRIC MOTOR UNITS. For most electric motor units, select a relatively clean and dry well-lighted indoor area with plenty of space for proper ventilation, cooling air flow and accessibility. Provide 1,000 cubic feet of fresh air per 5 horsepower. Locate the unit at least 15 inches (38 cm) from walls, and make sure the main power supply is clearly identified and accessible.
Unless the electrical components of the unit are specially protected for outdoor use, do not install an electric motor unit outdoors or in an area that will expose the electrical components to rain, snow or sources of appreciable moisture.
| WARNING FOR UNITS EQUIPPED |
| WITH ELECTRIC DRAIN VALVE |
aWARNING | The electric drain valve incorporates arcing or |
| sparking parts, such as snap switches, |
| receptacles and the like that tend to produce |
| arcs or sparks and, therefore, when located in a |
| garage, the compressor should be in a room or |
| enclosure provided for the purpose, or the |
| electric drain valve should be 18 inches |
| (457 mm) or more above the floor. |
| |
AMBIENT TEMPERATURE CONSIDERATIONS. Ideal operating temperatures are between 32°F and 100°F (0°C and 37.8°C). If temperatures consistently drop below 32°F (0°C), install the compressor in a heated area. If this is not possible, you must protect safety/relief valves and drain valves from freezing. If temperatures are consistently below 40°F (4.4°C), consider installing an external crankcase heater kit, especially if the compressor has difficulty starting.
aCAUTION | Never operate the compressor in temperatures |
| below -15°F (-26.1°C) or above 104°F (40°C). |
HUMID AREAS. In frequently humid areas, moisture may form in the pump and produce sludge in the lubricant, causing running parts to wear out prematurely. Excessive moisture is especially likely to occur if the unit is located in an unheated area that is subject to large temperature changes.
Two signs of excessive humidity are external condensation on the pump when it cools down and a “milky” appearance in petroleum lubricant.
You may be able to prevent moisture from forming in the pump by increasing ventilation, operating for longer intervals or installing an external crankcase heater kit.
NOISE CONSIDERATIONS. Consult local officials for information regarding acceptable noise levels in your area. To reduce excessive noise, use vibration isolator pads or intake silencers, relocate the unit or construct total enclosures or baffle walls.
MOUNTING
aWARNING Remove the unit from the skid before mounting.
The compressor must be bolted to a firm, level, solid foundation (such as a concrete floor) using the vibration isolation pads provided with the compressor. Installation on I-beams, open-grid flooring systems, or non-solid surfaces is not recommended.
Failure to install the unit using the pads provided with the unit and in accordance with the installation instructions as outlined in the operator's manual may result in mechanical failure to the compressor and cancellation of package warranty coverage. Ingersoll-Rand shall bear no responsibility for equipment installed on non-approved vibration isolation mounts or non-solid surfaces.
