0.0 SAFETY AND WARNINGS Safety instructions in the operators manual are bold-faced 0.1 SAFETY INSTRUCTIONS for emphasis. The signal words DANGER, WARNING and Before you install this air compressor you should take the CAUTION are used to indicate hazard seriousness levels as follows: time to carefully read all the instructions contained in this manual.

SAFETY SHUTDOWN CHECK HIGH AIR TEMPERATURE There is a high discharge air temperature shutdown function built into the Intellisys on each compressor. It is factory pre-set at 228°F (109°C). This function should be checked at regular intervals for proper operation, once a month is recommended. The procedure is: Block off the cooling air discharge.

1.0 RECEIPT OF EQUIPMENT 1.1 INSPECTION When you receive the compressor please inspect it closely. Any indication of careless handling by the carrier should be noted on the delivery receipt especially if the compressor will not be immediately uncrated. Obtaining the delivery man’s signed agreement to any noted damages will facilitate any future insurance claims.
2.0 INSTALLATION 2.1 VENTILATION Oil flooded rotary air compressors produce large amounts of heat. Because of this large heat production, the compressor must be placed in a room with adequate ventilation. If heated air from the compressor exhaust is allowed to recirculate back to the compressor, the compressor will overheat and shut down.
Page 13
2.3 PIPING (Continued) A dripleg assembly and isolation valve should be mounted near the compressor discharge. A drain line ISOLATION should be connected to the condensate drain. VALVE IMPORTANT: The drain line must slope downward from the compressor to work properly. NOTE: For ease of inspection of the automatic drain trap operation, the drain piping should include an open funnel.
Two types of dryers, refrigerated or desiccant, are used to correct moisture related problems in a compressed air system. Refrigerated dryers are normally specified where compressed air pressure dew points of 33°F (1°C) to SAFETY ISOLATION 39°F (4°C) are adequate. Desiccant dryers are required VALVE VALVE where pressure dew points must be below 33°F (1°C).

Some Examples of Operation 4.8 OPTIONS EXAMPLE 1 Several options are available with the Intellisys® The operator selects an unloaded run time of 2 minutes control. These include starter options, remote start/stop in the OPTION routine and starts the compressor. The option, power outage restart, sequencer control, and unit runs loaded for 8 minutes, unloads and then runs modulation control.
Page 29
The Power Outage Restart Option is turned on by Modulation Only plugging in the required option module and enabling it The "MODULATlON" control mode can be selected through the set point routine. The restart time delay, during the set point procedure on a compressor that which is adjustable from 10-120 seconds, can also be has the modulation option installed.
Page 30
The modulator valve is set at the factory to modulate at the compressor's rated pressure. For example a compressor with a 125 psig (8.6 bar) pressure rating will modulate up to 60% capacity when the system pressure is near the default off line setting of 128 psig. (8.8 bar).

5.4 INLET AIR FILTER The filter should be changed when the filter indicator shows red. The filter should be changed every 4000 hours and more frequently in dirty environments because coolant, coolant filter, separator element, and airend life are a direct function of how well you maintain and replace the inlet air filter.

5.6 COOLANT (Continued) After the unit is drained and a new coolant filter element is installed, refill the system with fresh coolant. Bring the receiver level of coolant up to the midpoint of the sight glass. Replace the fill cap. Start the compressor and run it for a short time.
5.8 COOLANT SEPARATOR ELEMENT WARNING To check condition of separator element, run compressor in full load mode and at rated pressure and select "SEPARATOR PRESSURE DROP" in display table. If display says "XX PSI", then no maintenance is required. If warning light is on and display says "CHG SEPR ELEMENT"...

5.9-2 Water Cooled Coolers (Continued) Improper lubrication can be a cause of motor bearing failure. The quantity of grease added should be carefully Cleaning controlled. The smaller motors must be greased with a lesser amount of grease than larger motors. The interior tube surfaces can be cleaned by several methods.
Page 39
5.10 MOTOR LUBRICATION (Continued) Grease relief along shaft can occur, precluding necessity WARNING of removing this plug if inaccessible. The inlet grease gun fittings and outlet plugs (or spring-loaded reliefs) are located at each end of the motor housing. The drive end reliefs protrude out the circumference of the lower portion of the end bell near a flange bolt.
5.11 LONG TERM STORAGE Follow these precautions to minimize damage from static electricity. Static can cause severe damage to General microcircuits. The factory, upon special request, prepares compressor units for long term storage. In such cases, a special 1) Make the least possible movement to avoid build- bulletin is supplied for storage and start-up procedures.

8.0 WATER QUALITY RECOMMENDATIONS Perhaps the largest contributor to scale formation is the Water quality is often overlooked when the cooling precipitation of calcium carbonate out of the water. This is system of a water cooled air compressor is examined. dependent on temperature and pH.
Page 57
Recommended equipment for on-site analysis includes a thermometer, pH meter, and dissolved oxygen meter. Dissolved oxygen and temperature must be measured on-site and it is recommended that pH be measured on-site. All other analyses should be performed by a professional water quality analyst. The Langelier Index (Ll) is calculated using the following equation and the tables found on the following pages.
