■ Remote Sump Configuration
When a remote sump arrangement is selected, the spray pump, suction strainer and associated piping
are omitted; the unit is provided with an oversized outlet to facilitate drainage to the remote sump.
** Gallons shown is water in suspension in unit and piping. Allow for additional water in bottom of remote sump to cover pump suction and strainer during
operation (12" would normally be sufficient).
Unit dimensions may vary slightly from catalog. See factory certified prints for exact dimensions.
