Target Pressure -
This is the package discharge pressure that the controller would maintain. For
fixed speed units, a pressure rise of 3psi above the target value would result in an unload action.
For flow modulating units (e.g., variable speed or inlet throttling), a pressure rise above the target
would result in flow modulation. Note that inlet throttling is only available with the Fixed Speed
models. DO NOT EXCEED THE MAXIMUM OPERATING PRESSURE ON THE COMPRESSOR
NAMEPLATE. See
“Operational Settings” menu in Controller Operating and Service Manual.
Operation at excessive discharge air pressure can cause personal injury or
damage to equipment. Do not adjust the full discharge air pressure above the
maximum stamped on the unit nameplate.

Operating Mode
- See "Operational Settings, Operating Mode" menu in Controller Operating and
Service Manual.

Enclosure
- Check for damaged panels or doors. Check all screws and latches for tightness. Be
sure doors are closed and latched.
The compressor starts and stops automatically. Automatic restarting can
cause injury or death. Open, lockout and tag out main disconnect and any
other circuits before servicing the unit.
After an emergency stop, be sure that the pressure in the air/oil reservoir is less
than 5 psig. Wait one minute or more before restarting.
