WARNING

DO NOT clean the interior of the reservoir with water or detergent. Introduction of water or detergent into the unit will permanently damage the pump.

3.SERVICE PROCEDURES

3.1 Introduction

Other than routine cleaning and the replacement of worn suction tube O-rings, the SDU is maintenance free. After long use, the pump vanes and pump shaft seal may require replacement due to wear. Frymaster recommends worn pump vanes and/or pump shaft seals be replaced by an FAS, but store personnel may perform these service actions without voiding the warranty.

3.2 Replacing Worn or Damaged O-Rings

If pump efficiency degrades, it is likely that the O-rings on the suction tube are worn or damaged. To replace the O-rings, follow the steps below.

1.Lift the pump assembly straight up and out of the handle assembly.

2.Remove the worn or damaged O-rings from the grooves at the bottom of the suction tube and replace with new O-rings. Apply Accrolube with Teflon grease or equivalent to bottom 2 inches of the suction tube.

3.Insert the suction tube through the tube bracket in the handle and into the receiver on top of the reservoir. Push down on the pump assembly to make sure the suction tube is fully seated.

3.3 Replacing Worn Pump Vanes and/or Pump Shaft Seal

Depending upon the amount of use, the vanes in the pump assembly will eventually wear, reducing the efficiency of the pump. The pump shaft seal can also become worn and start to leak. A kit for replacing the vanes and the seal is available. The pump shaft seal can also be purchased as a separate item. To replace the pump vanes, and/or the pump shaft seal, follow the steps below (refer also to the illustration on Page 6).

1.Loosen the setscrew securing the pump handle to the pump shaft and slip the handle off the shaft. If unit is a BKSDU remove the eight screws that secure the pump cover in place and remove the cover.

2.Remove the five screws securing the front cover and remove the cover.

If replacing the pump shaft seal only, remove the old seal and install the replacement as shown in the illustration below, then go to Step 5.

If replacing the pump vanes, go to Step 3.

3.Grasp the pump shaft and carefully pull the rotor assembly straight out of the pump housing far enough to expose the vanes. IMPORTANT: The vanes are spring-loaded. Use one hand to hold the vanes while pulling the rotor assembly the rest of the way out of the housing. Carefully release the vanes and discard the worn vanes, springs, and rods.
