CAUTION
Running the compressor package in reverse for any significant length of time will void
the warranty.
If the power cord is not wired properly the compressor will run in
reverse and there will be no pressure differential on the pressure gauges. Turn the
system off immediately. Follow the instructions in Step 5, below, to rewire the power
cord correctly.
1) Switch on the compressor package’s circuit breaker.
If the system was supplied with the optional electrical protection device, proceed
with the following steps. If the optional electrical protection device is not included
with the system, skip to step 11.
2) Open the door of the EPD enclosure.
3) Check the status of the indicators. When the LNP is first powered up, both the Read
Memory indicator (yellow) and the Output On indicator (green) will “Slow Flash”. The
Under Voltage and Phase Loss or Unbalance indicators (yellow) will be “Steady On”.
