1-1MICRO-FLO BUILT-IN SERIES FILTRATION SYSTEMSCHAPTER 1: DESCRIPTION AND SPECIFICATIONSMicro-Flo Built-In Series filtration systems are available in sizes to handle quantities of oil up to 120pounds. They can be fabricated to match Dean gas (Super Marathon & Decathlon) or electric fryers(Cool Zone & Flatbottom Series), or in stand-alone cabinets. Micro-Flo filtration systemsincorporate a "gravity drain" design. The oil return line can be configured overhead (prior to 1994),internally plumbed, or returned by the hose & nozzle.Prior to 1994, handle-operated ball valves or optional "push-pull" linkage-operated ball valvecontrols located in the filter cabinet were available. Current systems are configured with the oil-return and drain valve controls located in each fryer cabinet.1.1 ConstructionMicro-Flo Built-In filters are constructed with the following features:¯ Fully welded, heavy gauge steel, with a removable stainless steel filter pan.¯ Internal oil return lines are plumbed with either a "push-pull" valve system in the filtercabinet or manual drain valves at each fryer.¯ A 1/3 HP motor, coupled with a 5 GPM pump returns filtered oil to the fry vessel. An 8GPM pump (optional) is also available.1.2 Operating ControlsMicro-Flo Built-In filters are equipped with the following operating controls:¯ The "ON-OFF" power switch is mounted on the front control panel of the filter cabinet. Ifthe filter is equipped with an optional heater, a three-position switch (Heater/Off/Pump) isincluded as the power switch.¯ Individual fryer drain valves control which fryer is filtered, reducing operator error.¯ Prior to 1994: Oil-return valves are either "push-pull" controls or "lever-operated" manualball valves; the push-pull controls are in the filter cabinet and the "lever-operated" valves areat each individual fryer.¯ 1994 and later: Oil-return valves are push-pull controls, located within each individual fryercabinet. A manual "hose-disconnect" valve is located in the filter cabinet.
