Safe Servicing Practices Safe Servicing Practices To avoid personal injury and/or property damage, it is important that Safe Servicing Practices be observed. The following are some limited examples of safe practices. 1. DO NOT attempt a product repair if you have any doubts as to your ability to complete it in a safe and satisfactory manner. 2. Before servicing or moving an appliance, remove the power cord from the electrical outlet, trip the circuit breaker to the OFF position, or remove the fuse. 3.

Features Electrical components (SECTION D) Power Unit Mechanism (SECTION C) Cabinet (SECTION B) How the compactor works The compactor compresses household trash up to 1/6 of its original volume. It will compact normal household trash including milk cartons, glass and plastic bottles, containers and jars, tin cans, wrappings, boxes, food wastes, etc.
Section A – Installation Your compactor has been designed to require minimum space without loss of capacity whether free-standing or built-in. Free-Standing As shipped, the compactor is only configured for built-in installations. This appliance can be converted from builtin to free-standing with the use of Toe Kick Accessory Kit Model 15TCTK (sold separately). If additional cord length is required for free-standing installation, remove the cord clamp and wire tie on the back of the unit.
Section A – Installation Leveling the Compactor cord clamp The compactor is equipped with a 6-ft. long power cord. Use the cord clamp to prevent excess power cord from being pinched beneath the cabinet during installation or service. Your compactor has four adjustable levelers; (2) rollers in the rear and (2) legs in the front. They allow you to adjust for uneven floors and also trim the unit up to fit an undercounter installation.
Section B – Cabinet H G a F C, D b Cabinet Legend The compactor’s main cabinet supports and encloses a number of sub-assemblies. These include the trash bucket, the door, the motor, the ram, and the electrical controls and components. A. B. C, D. E. F. G. H.
Section B – Cabinet Trash Bucket Bucket Handle Remove Remove and Replace To remove the bucket completely from the cabinet for repairs or cleaning, follow these instructions. The plastic bucket handle may receive a lot of “wear and tear” simply because the operator uses it every time he or she places trash into the compactor, or removes or replaces the bag. If the handle is scratched, chipped or broken, replace it. Bucket Handle Screw 1.
Section B – Cabinet Slide Rails (Cabinet) Slide Rails (Bucket) Remove and Re-install Remove and Re-install The compactor’s slide rails may become bent from misuse or the ball bearings may become worn. Rail Spring Clips Screw Bucket Screw Rail Nut Screws 1. Remove four Phillips head screws that secure the left slide rail to the bucket. Remove the rail. 2. Repeat Step 1 for the right slide rail. 3. Installation is the reverse of removal. Screws 1. Remove trash bucket assembly.
Section B – Cabinet Door Assembly REVERSE DOOR Hinge POSITION REMOVE AND RE-INSTALL The compactor comes from the factory with the door in the right-hand opening position. Use the following instructions to reverse the door. The heavy-duty door could become dented, scratched or bent and require replacement. Door removal is also necessary for some service procedures. 1. Remove the door (see Remove and Re-install). IMPORTANT: Firmly support the door during removal and re-installation.
Section B – Cabinet Safety Interlock Actuator TRIM PIECE Remove and Re-install Upper Hinge Pin This safety device prevents the compactor from operating except when the door is closed. NOTE: If the interlock actuator should break off, the compactor will not function; replace it promptly. ACTUATOR SCREW 4.

Use an electrically-insulated tool to short the capacitor terminals together.
Section D – Electrical Components 3. Remove two Phillips head screws and wire leads from the capacitor. 4. Discharge the capacitor (see Warning above). 5. Use an ohmmeter or multi-meter set on the “Ohms times 1000” scale (if available) to check resistance across the wire terminals. The needle should jump toward zero ohms and quickly move back to infinity. (Note: Some less-sophisticated meters will only tell you if the capacitor is good or bad.) 6.
Section E – Troubleshooting Troubleshooting Table Problem No power to compactor. Compactor will not operate. Possible Cause 1. Power cord not securely plugged in. 2. House fuse blown or circuit breaker tripped. 1. Key switch in OFF position. 1. 2. 3. 2. 3. 7. Defective key switch. Safety interlock switch not engaged when door is closed due to a: a. Broken actuator. b. Debris prevents door from closing. c. Damaged or deformed door. d. Gasket damaged preventing door from closing.
Section E – Troubleshooting Troubleshooting Table (Continued) Problem Noticeable odor coming from trash compactor. During compaction cycle the motor runs but the ram doesn’t move. Compactor does not compact cans or bottles. Compaction force appears weak. Compactor stops during operation. Possible Cause 1. Active section of deodorant disk has expired. 2. Entire deodorant disk has expired. 3. Odor causing trash is trapped outside of the trash bucket. Correction 1.
Section E – Troubleshooting Troubleshooting Table (Continued) Problem Compaction cycle repeats without pressing START. Motor runs when the START button is pressed and stops running once released. Motor hums after ram returns to the up position. Ram continues to run with the door open. During NORMAL compact mode, ram runs down and doesn’t return up. Motor hums after reaching the bottom position. Possible Cause 1. Defective start switch. 2. Defective upper limit switch assembly. 1.
