6.1 Troubleshooting the Vertiv™ VRC
Message or Problem Possible Cause Suggested Action
High
Temperature
Loss of
power
Check the input cord and ensure that it is connected to the specified power source.
Reset building input circuit breaker.
Poor
Internal
Airflow
Confirm that blanking panels are installed in any unused rack space to prevent short-
cycling of Vertiv VRC airflow.
Confirm there are no obstructions such as cable bundles or equipment chassis blocking
the internal supply and return airflow paths.
Review and follow Preventive Maintenance procedures in the Vertiv VRC user manual.
Check the front and rear filters. Replace them if they are dirty as described in the Vertiv
VRC user manual.
Poor External Airflow
Confirm that the rack has unobstructed front and rear clearances of at least 12 in. (305
mm).
Verify that the heat rejection duct at the rear of the rack is free of debris and airflow
obstructions.
The warm ambient air influences the indoor temp because the system is not sealed.
Alarm temperature setpoint is
too low. Adjust the setpoint temperature that triggers the alarm. Refer to the Vertiv VRC user
manual.
Thermal overload
Make sure that the actual heat load is not above the maximum rated value. The Vertiv
VRC's maximum load at 30°C (86°F) is 3,3 kW; the Vertiv VRC's cooling module is rated
to remove 3.5 kW worth of heat.
Fan malfunction. Contact Vertiv Technical Support.
Compressor malfunction. Contact Vertiv Technical Support.
Air mixing in the rack due to
gaps between front and rear of
rack.
Equipment or blanking panels should be added to prevent this. The equipment should
cover the whole width of 19 in. profile, with adapters. Add additional blanking panels or
equipment. Airflow should not be able to mix from front to rear; this will inhibit the cool
airflow up the front of the rack.
Water Leaking from or into
the Cabinet
Internal drain line clogged or
kinked Check the condensate drain line for obstructions and verify it is not kinked and runs
freely.
Cabinet not level Confirm that the leveling feet are adjusted to the make the cabinet level.
Drain line is not connected to
condensate pump.
Confirm that the condensate drain line is properly connected to the condensate pump
outlet. Loosen the O-ring clamp if necessary and press the line onto the outlet nozzle,
tighten clamp.
Low Temperature
Alarm temperature setpoint too
high.
Adjust the setpoint temperature that triggers the alarm.
Fan malfunction. Contact Vertiv Technical Support.
Compressor malfunction Contact Vertiv Technical Support.
