Shortening Recirculation System Installation

PITCO LJ-FBG Frying System

The Shortening Recirculation System directs cleaned shortening from the filter pan, through the fryer drain,
back to the filter pan. This allows the required 10-minute filter cycle to run at the same time that frypot is being
cleaned. It is estimated to take 3-4 hours to install. For installation help, please call 603 225-6684 Service/Parts
