Air filter replacement

In dusty environments, the use of an air filter is strongly recommended. When used, it should be replaced at least once a year. Do not install a wet filter on a rectifier. To remove the filter, simply unscrew it. Install the new one by reversing the operation. Contact your local Liebert representa- tive for ordering information on air filters.

Fan unit replacement

Visually inspect the airflow intake for any obstruction by foreign objects or excessive dust and dirt build-up. Open both AC and DC breakers. If the rectifier is a Helios Rectifier 100/48, remove it from the power shelf. Inspect the air outlet for obstruction by foreign objects. Visually inspect the air outlet of the power shelf (Helios Rectifier 100/48) or the cabinet (Helios Rectifiers 200I/48 and 200E/48). The fan unit is field replaceable. Contact your local Liebert representative for ordering information on replacement fans. To install a new fan unit, refer to the appropriate procedure and associated figures in the maintenance chapter of the applicable rectifier user manual listed in

6.0- Reference Documents. If a problem is detected inside the rectifier, contact Liebert Glo- bal Services at 1-800-LIEBERT.Do not attempt to open the unit for on-site servicing.
