Current Transformer
This device may be required to provide a 0-5 ampere signal to one or more devices located
in the control panel. When supplied by Ingersoll-Rand, the current transformer is often
shipped loose for installation by the customer.
WARNING
An appropriate grounding strap should be attached to the motor and a suitable
ground. DO NOT CONNECT TO A PLANT GROUND CIRCUIT.
Optional Switches
Optional switches such as pressure, temperature, flow, etc. supplied by Ingersoll-Rand but
mounted by the customer must be connected to the control panel. Information on how to
wire these devices to the control panel is shown on the Electrical Schematic.
Lubrication
NOTE
The initial fill of lubricant for the Centac compressor should be installed under the
supervision of an authorized Ingersoll-Rand Technical representative.
Cleanliness of the lubrication system is of vital importance to the Centac air compressor.
The system is flushed and fully tested at the factory. The sump access cover should be wire
sealed as shipped from the factory. If the wire seals have been violated, then the following
procedure must be followed under the supervision of an authorized Ingersoll-Rand
Technical representative.
Piping Flush
1. Remove the sump access cover. Thoroughly clean the sump of any shipping oil and dry
with lint free rags.
2. Fill with recommended oil to the proper level and replace sump access cover.
3. Disconnect the oil piping at the entrance to the gear casing and use a flexible oil line to
route the oil to the sump in the baseplate.
4. Circulate the oil for a minimum of one hour using the prelube pump. Optimum flushing
temperature is 100°F.
5. Tap any welded piping with a plastic or lead hammer during oil circulation to dislodge
any foreign material lodged at the welded joints.
6. Change position of the transfer valve at 15 minute intervals on systems having dual oil
filters and/or coolers.
7. Shut off the prelube pump.
