The Maintenance Bypass Cabinet intake fans
contain filters that will need to be replaced or
cleaned periodically, depending on the
surrounding environment. Check by noting the
condition of the two filters. If filters are dirty,
replace or wash them. The filters may be taken out
of the UPS for replacement or cleaning by
removing the plastic cover over the filter frame.
Use caution when replacing filters when fans are
running.
The fan filters are washable and can be reused.
To wash these filters, place them under a running
faucet (with the dirt side down) to remove dirt and
dust. Blot dry with a towel and allow air-drying
before reusing.
