1-800-KEATING |GAS FRYER - SERIES PRE-2000Oil BreakdownAs part of a “Preventive Maintenance Program”, theoil in your fryer needs to be fi ltered regularly to avoidbreakdown. The initial investment in the frying systemis less than the total overall costs of oil during the lifeof the fryer, and with regular fi ltering, you can realizesubstantial savings in oil costs as well as maintenancecharges.LIMITED CALIBRATION(Less than 25° difference)You will need:One screwdriver with 1/8" wide fl at bladeOne accurate fryer thermometerFigure 9Thermostat calibration with knob on1. Set thermostat to desired frying temperature.2. Allow fryer to cycle three times.3. Place an accurate thermometer in the oil at thetip of the thermostat bulb.NOTE: Locate thermometer in same position forevery calibration.4. If calibration of fryer is found to be less than 25°Foff, simply loosen three dial plate retaining screws,rotate dial plate to match thermometer reading andtighten screws. If it is more than 25°F off contact aqualifi ed service company..DO NOT ADJUST THE THERMOSTAT SET SCREW - ITVOIDS ANY WARRANTY ON PART.Thermostat Bulb PositioningBEFORE REPLACING, TEST THERMOSTATSNOTE: Operational problems can easily be correctedby thermostat bulb positioning.Keating’s patented thermostat application is accuratewithin 2°F of the dial setting between 250°F – 350°F.This accuracy is attained only if the thermostat bulbis placed properly against the heat transfer tube. Toquickly and accurately test for proper bulb placement,a single thickness of writing paper should be pulledthrough between the tube and the bulb with mediumresistance.*1. *For 14" Gas Fryers:• The end of thermostat bulb should touch theburner tube.2. For 10x11", 18" + Up Gas Fryers:• If the bulb is too loose, the paper will slipthrough with little or no resistance. A fryer witha thermostat bulb that is too loose willovershoot.Overshoot: The thermostat takes a long timeto cycle and then misses its preset temperatureby 20°F - 40°F yielding a poor quality product.overshoot.• If the bulb is too tight, the paper will either notpull through or it will tear. A fryer with athermostat bulb that is too tight will short cycle.Short Cycle: The thermostat will cycle rapidlywhile the fryer is in the idle mode; thetemperature will be erratic.Figure 10Thermostat Bulb Positioning 10x11, 18 & UpREQUIRED TEST THERMOSTATMultimeter (for testing continuity)CHECKING CONTINUITY WITH THE MULTIMETER1. Rotate the thermostat shaft until an audible clickis heard.2. Rotate the thermostat shaft left and right tentimes causing the switch to click on and off tentimes, while using the Multimeter to verify continuity.3. If the switch does not show continuity during allten trials, replace the thermostat.DISASSEMBLING THE THERMOSTAT WILL VOID THETHERMOSTAT WARRANTY.1. Set compression ring onto capillary end of bulbfi nger tight, 1/2" from end of capillary.2. Insert new thermostat bulb through control panelback.3. Apply oil resistant fl exible sealant onto compres-sion fi tting thread before installing fi tting into fryervessel.11
