NOTICE
Risk of improper filter installation and filter collapse. Can cause equipment damage.
Pleat direction is non-standard. Use only short-pleat filters (see Figure 97). Long-pleat filters
are subject to collapse at high airflows.
To maximize the performance and reliability of Liebert DS equipment, use only Liebert filters.
