Symptom #2 Machine is running and the display

has a flashing alert triangle and indicates “HPC

Fault” after the left arrow is pressed

1. Navigate to the event log on the Service menu.

Scroll down to HPC Fault EO5. Open the event

and view when and how often HPCO Fault has

occurred.

2. If this is a one time event it may be intermittent

and caused by conditions around the unit

changing. For example: High ambient

temperature, water turned off to condenser (water

cooled unit) etc.

3. Run the system to see if the control trips at the

rated pressure. If HPCO opens at a pressure

significantly lower than the control setting of 450

psig replace the HPCO.

lbs) find the root cause - Fan motor, dirty condenser,

refrigeration system issue, etc.
