Page 6: System Diagram
Fig. (1) Simplex, two stage air compressor process. FS Curtis manufactures a broad array of compressor configurations to satisfy the needs of our diverse customer base. Despite this diversity, all FS Curtis two stage compressor configurations work off the same basic cycle. Air is drawn into the compressor through the air intake and filter assembly. - Page 7 CA / CT SERIES CAP600 Page 6 of 30 REV D July 2013 Duplex Units Exact orientation of your system's Air Intake Alternator components may be different from the Air Compressor Pressure Switch layout in the figure.

Page 8: Receiving
FS Curtis strongly recommends that any or all person(s) in charge of installing, maintaining, or servicing one of our compressors read and understand the entire contents of this manual and the respective compressor installation and operating instruction manual in order to perform such duties safely and efficiently. -
Page 9: Freight Damage
CA / CT SERIES CAP600 Page 8 of 30 REV D July 2013 FREIGHT DAMAGE The transportation industry has adopted a modification with regard to the handling of obvious and concealed damage claims. Therefore, it is extremely important that you examine every carton and crate as soon as you receive it. -
Page 10: Installation Procedure
The unit should never be operated at ambient temperatures above 104° F or below 32° F. If the ambient temperature is below 40° F, FS Curtis recomm ends using Arctic oil. Maintenance checks are required daily, thus three (3) feet of space needs to be provided around the compressor for proper inspection. - Page 11 If you wish to utilize an installation method other than the approved methods described in Table (2), please contact your local distributor. FS Curtis neither states as fact, nor implies that the above list of Acceptable/Unacceptable mounting is all-inclusive. Contact your local distributor for more information.

- Page 13 Run a clean pipe to the tank discharge opening, bushing up or down as necessary with clean bushings and fittings. Note that the more bushings and fittings placed in the air distribution system, the greater the opportunity for air leaks and breaks. FS Curtis recommends the installation of drip legs in the distribution piping.

Page 14: Post Installation Checklist
1. Remove all installation tools from the compressor and check for installation debris. Abrasive dust can seriously damage the air intake and belt assemblies. 2. All FS Curtis compressors are shipped from the factory filled with the required amount of Curtis Lube Plus Compressor Lubricant specially formulated for Curtis Compressors. The oil level should register in the center of the oil sight glass or between the high and low marks on the dipstick. -
Page 15: Electrical Requirements
National Electrical Code (N.E.C.), O.S.H.A. code and/or any local or state codes having precedence. All FS Curtis compressors come with a factory installed, pre-wired starter, if you wish to provide your own starter, please contact your local distributor for more information. Check the electrical supply for voltage, phase, and frequency to see that they match the nameplate stampings on the motor, magnetic starter, solenoids, and other controls. -

Page 19: Start-Up Procedure
CA / CT SERIES CAP600 Page 18 of 30 REV D July 2013 For the first weeks, the compressor needs time to “break in.” The belt requires time to stretch and fit into the surface of the pulleys. The piston rings need time to seat themselves into the cylinder walls, and bearings need to wear into place. -
Page 20: Shut Down Procedure
CA / CT SERIES CAP600 Page 19 of 30 REV D July 2013 Maintenance Shut Down Procedure The following procedures should be followed when stopping the compressor for maintenance or service. WARNING! Never assume a compressor is safe to work on just because it is not operating. It could start at any time. -
Page 21: Maintenance Schedule
CA / CT SERIES CAP600 Page 20 of 30 REV D July 2013 Maintenance Schedule To assure maximum performance and service life of your compressor, a routine maintenance schedule should be developed. A sample schedule has been included to help you develop a maintenance schedule designed for your particular application. -
Page 22: Oil
Air Compressors. Non-Detergent type with anti-foam, anti-rust and oxidation inhibitors. Under normal operating temperatures, use FSC-1000 ISO68 CURTIS-LUBEPLUS. In areas with very hot ambient air temperatures, FS Curtis recommends using ISO100 FSC- 1000A CURTIS-LUBEPLUS. 1. For proper lubrication the compressor shall not be operated below the minimum or above the maximum R.P.M. -
Page 23: Low Oil Guard
To help prevent catastrophic damage, FS Curtis provides an option for a Low Oil Guard, which shuts the unit down when the oil level has dropped below the low oil mark on the sight glass or dipstick, see Fig (12) for proper oil level. FS Curtis’s low oil guard utilizes a magnetic float switch CAUTION! A low oil guard is not a substitution for proper maintenance. -
