5.3 Daily Filtration Operation WARNING
Use caution and wear proper protective clothing. The oil to be filtered is at or near
350°F (177°C). Ensure all hoses are connected properly and drain handles are in
their proper position prior to operating any switches or valves. Failure to do this can
result in severe burns.
WARNING
Drawings and photos used in this manual are intended to illustrate operational,
cleaning and technical procedures and may not conform to on-site management
operational procedures.
5.3.1 General Overview
The filter pump is turned on only after the oil is brought to operating temperature and drained into
the prepared filter pan. The filter motor is then engaged and oil is drawn through the filter leaf
assembly and pumped back into the frypot. The frypot drain valve remains open during the filtering
process. The oil is cycled through the filter leaf assembly for approximately 10 minutes (see
computer section for specific instructions). At the end of 10 minutes, the drain valve is closed,
allowing the oil to pump back into the frypot. The pump should run for 15-30 seconds after bubbles
appear in the frypot to ensure all oil or shortening is pumped from the drain pan and the oil-return
lines. The frypot oil level should return to the top OIL LEVEL line. If not, add fresh oil or
shortening to obtain the proper level. Remember, the oil is at operating temperature during all
filtration procedures.
The filter pump can be activated with a manual On/Off switch located under the fryer control panel
if the oil-return, drain-flush or wand/dispose valves fail to activate the pump when opened. Contact
an authorized service technician immediately for repair.
Refer to specific store procedures for correct filter operation. Additional information can be found
in the computer section of this manual.
