4.10.4 Draining and Refilling Vats, and Disposing of Oil
When cooking oil is exhausted, drain the oil into an appropriate container for transport to the
disposal container. Frymaster recommends a McDonald’s Shortening Disposal Unit (MSDU). Do
not drain deep clean (boil-out) solution into an MSDU. NOTE: If using an MSDU built
before January 2004 the filter pan cover must be removed to allow the unit to be positioned beneath
the drain. To remove the cover, lift up on the front edge slightly and slip the oil guard up and pull it
straight out of the cabinet. Refer to the documentation furnished with your disposal unit for specific
operating instructions. If a shortening disposal unit is not available, allow the oil to cool to 100°F
(38°C), then drain the oil into a METAL container with a capacity of FOUR gallons (15 liters) or
larger to prevent oil from spilling.
4.10.4.1 Disposal for Non-Bulk Oil Systems
This option is used to dispose of old oil into either an MSDU or a METAL pot.
1. Remove the filter pan and position the MSDU or METAL container with a capacity of FOUR
gallons (15 liters) or larger under the fryer to drain the oil.
