Vertiv I Liebert LPC I User Manual
The following steps need to be followed during inspection and maintenance of the
Electric heater:
• Check the rust on the electric heater. Use an iron brush to get rid of the rust, if possible
or replace it if the rustiness is immense or if there is some damage.
• When heating is required but heating is not effective or no heating effect is observed, a
multi- meter should be used to check whether the cable connected to the temperature
switch is functioning correctly to ensure that the three temperature switches are
normal.
• If the cable is not functioning properly, remove the electric heater and check if the
manual reset switch is disconnected. Next, check the automatic reset switches or the
electric heater pipe for damage or faulty condition.

Drainage check
When inspecting the drainage, check if there are no unwanted substances, debris, alien
objects, or particles in the water pan. Check the drainage for leakage too.
The check has to be conducted periodically on a regular basis.
