dV/dt cooling requirements
The installed filter's cabinet cooling system provides its
required cooling. This system consists of an inlet air filter and
outlet air fan, located in the cabinet door, and an air outlet
vent on top of the control cabinet. The filter and fan require
periodic maintenance for maximum efficiency.
Maintenance
Inspect the dV/dt filter cabinet cooling system periodically to
assure maximum uptime and effectiveness. Inspect the
cooling fan and inlet air filter at least once every three
months. Clean the filters with an air jet and dust the fan to
prevent dust buildup in the fan motor and bearings. Replace
the fan every three to five years.
