SAFETY PRECAUTIONS

ALWAYS UNPLUG COMPACTOR FROM WALL OUTLET BEFORE SERVICING.

The service information is intended for use by a service technician who is familiar with proper and safe procedures to be followed when repairing electrical appliances and who is equipped with proper tools and testing devices. Repairs attempted or made improperly can result in personal injury or property damage. Hazards may develop from improper assembly or adjustments. While making repairs, persons not having the proper background may subject themselves to the risk of injury or electrical shock which can be serious or even fatal.

IMPORTANT - NOTE TO THE CONSUMER

If you perform service on your own Broan products, you must assume responsibility for personal injury or property damage which may result.

MODEL AND SERIAL NO. IDENTIFICATION

The specification label with model and serial numbers is located on the inside of the cabinet. It is visible after opening the drawer.

TRANSPORTING COMPACTOR

When transporting compactor, the ram should be electrically or manually extended down into the drawer, preferably against a load of stacked newspapers or other suitable material. If this is not done, damage to the trunnion nut may occur.

Never transport compactor on its back or front. Damage to the gearbox may occur. If it cannot be transported upright, it is preferable to place it on its side.

MANUALRAISINGAND LOWERING OF RAM

Unplug compactor cord from wall socket. Remove back panel. The ram may be raised or lowered manually by using a 15/16" socket to turn the drive screw nut. Clockwise will lower ram, counterclockwise will raise it.

BAG INSTALLATION

DO NOT use plastic bags other than those which have been designed for use in this compactor. Unauthorized bags can become caught in the mechanism.

With the drawer extended to the second stop, release the container latch and swing open door. Slide bag into drawer from front to back. Fold bag over top rim of drawer on all sides.

PREPUNCHED HOLES

Press bag into all corners of the drawer. Smooth and shape the bag carefully - this will prevent the bag from being torn by the ram during compaction.

DRAWER BUTTONS

Using buttons on side of drawer, button bag in place by using prepunched holes in side of bag. NOTE: If you have difficulty installing bag, move drawer to second stop by lifting front of drawer slightly and pulling forward (place on rug or other surface to protect floor). This

will clear back of container from housing for easier bag installation.

Swing door shut and latch it. Bag is locked between door flange and drawer. When door is closed and latched properly, door guide “V” will be snug in “V” groove in drawer flange. Bag should be captured in “V” guide. Failure to align “V” properly or to latch drawer to door will cause the compactor to function improperly.

CABINET REPLACEMENT - POWER PACK REMOVAL

A box or similar stand approximately 11” high x 15” long x 7” wide is recommended for power pack removal. The box must be able to support 60 lbs. or more since you will be placing the full weight of the power pack on it.

1.Unplug compactor from socket.

2.Remove drawer assembly from cabinet.

3.Remove Air Scentry tray and control panel.

4.Remove key switch control bracket assembly. Remove back panel.

5.Place box in cabinet and lower ram manually by turning 15/ 16" nut on sprocket clockwise. Box should support weight of power pack.

6.Remove the four 5/16" nuts supporting the power pack in the cabinet.

7.Disconnect ground wire attached to cabinet.

8.Turn 15/16" nut counterclockwise causing power pack to lower down out of cabinet. Pull power pack out through front of rear of compactor.

If you are replacing the cabinet, remove remaining parts from old cabinet and install on new. See appropriate sections of service manual.

Reverse procedure to install power pack. Be sure the weld strip, grommets, and spacers are in place. The lock nuts should be torqued to 5 ft./lbs. (60 inch/lbs.). Do not overtorque.

Be careful not to pinch or nick any wires when installing power pack in cabinet.

CONTROL PANEL

On units with a bag storage compartment, removal of the storage compartment will make replacement of the control panel easier.

1.Remove drawer assembly.

2.Remove the four screws securing the air scentry tray and the bottom of control panel to the cabinet.

3.Pull bottom of control panel out slightly and then up.

When installing the control panel, make sure lip on inside of control panel snaps behind the bend in the control panel bracket.

STORAGE COMPARTMENT

Remove two screws on rear of compactor and the two 5/16" hex head screws inside the storage compartment. Slide compartment back and lift off.

DRAWER ASSEMBLY

1.Pull out drawer until it stops.

2.Lift drawer slightly, then pull out drawer to second stop.

3.Lift drawer up and out of compactor.

FOOT PEDAL (MODELS 1050 & 1051 ONLY)

1.Remove foot pedal retainers from each side of pedal.

2.Push foot pedal hinge pin out, catch foot pedal spring as it comes free.

DOOR LINER

Remove the door from the drawer by unlatching the door and removing the hinge pins. The door liner can be removed from the door by removing the toe space cover and all screws holding the door liner to the door. Slide the door liner to side of door and lift off. (Models 1050 and 1051 will require removal of the foot pedal prior to toe space cover.)

DRAWER AND BASE ROLLERS

All four of the rollers are secured with a 1/2" hex nut and slotted for screwdriver. Roller nuts are installed using LocktiteR and torqued to 20 foot pounds. Rollers are pregreased and should require no lubricant.

BOTTOM ASSEMBLY

1.Unscrew level legs from base. Remove tee nuts that legs screw into.

2.Remove screws securing bottom assembly to the cabinet.

3.Lower the bottom down into the cabinet, back end first, then bring it up and out through the notches in the bottom flange of the cabinet.

REMOVING PLASTIC BAGS FROM TRUNNION NUT

Only the trash compactor bags specifically designed and sold by Broan for use in the compactor should be used. Regular plastic garbage bags used in place of the Broan bags may be drawn into the mechanism. Removal of those bags is not covered by the warranty.

To remove bag from trunnion nut:

1.Remove back of compactor.

2.If possible to slide drawer slightly, remove the door by sliding out the two hinge pins and then prying the door over the lip on the drawer.

3.Liberally spray drive screw and trunnion nut with WD-40R or similar.

4.Use 15/16" socket, and extension, and a 16" ratchet (for leverage) and manually turn the drive screw clockwise. (See section on manually raising and lowering ram.) By turning the drive screw clockwise, you will help back the bag out of the trunnion nut.

5.After removing bag, clean drive screw and regrease it with wheel bearing grease.

TRUNNION BEARING

GEARBOX

1.Remove sprocket and drive pin.

2.Pull out trunnion bearing.

Grease trunnion bearing inside and out with wheel bearing grease prior to reinstalling.

MOTOR TRUNNION

1.Remove motor, gearbox, spocket, and screw guard.

2.Use 13/16" wrench to remove bolts securing links to motor trunnion.

When reinstalling, bolts should be torqued to 45 foot pounds.

SPROCKET

1.Line up one of the 3/8" holes in the sprocket with the 3/8" hole in bottom center of gearbox. Insert 3/8" steel pin or bolt through sprocket hole into front and rear gearbox holes.*

2.Loosen and remove 15/16" nut on the drive screw. When reinstalling torque to 65 foot pounds and apply Locktite® to threads.

*If the sprocket is too damaged to be able to use on of the holes to secure it, chip away the remaining sprocket, remove the drive pin and then insert a screwdriver through the hole to provide a means of keeping the drive screw from turning.

INSERT

3/8” DIA. PIN

1.Lower ram manually until there is approximately 11" to 12" between the ram and the bottom assembly.

2.Remove the four 3/8" nuts securing motor to gearbox, slide motor out and rest it on the front trunnion assembly.

3.Turn sprocket until two holes in sprocket line up with the two socket head cap screws that hold the gearbox to the motor trunnion.

4.Remove the two socket head cap screws with a 5/32" hex key. NOTE: The screws thread into 2 nuts which rest in slots in the motor trunnion. Be careful not to lose the 2 nuts when the screws are removed.

5.Tilt gearbox forward and remove chain. Lift gearbox out.

When installing gearbox, Locktite® should be applied to the socket head cap screw nuts.
