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.
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.
DOOR LINER - LATCH ASSEMBLY
1. Unplug compactor from socket.
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.
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.
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.
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 ser-
vice 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.
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.
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 stor-
age 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

the door. Another switch located against the interlock switch is
to provide the “No-Jam” circuitry function. This switch is nor-
mally open and bypasses the interlock to provide “No-Jam”
capability. It can be replaced in the same manner as the inter-
lock switch.
SWITCH LOCATIONS
TO REPLACE INTERLOCK SWITCH
1. Remove air scentry panel assembly.
2. Disconnect leads one by one and attach to new switch.
TRUNNION NUT
1. Remove back panel, drawer assembly and air scentry panel.
2. Lower ram manually to approx. 10-1/2" from the bottom
assembly onto box or stand described in “CABINET RE-
PLACEMENT/POWER PACK REMOVAL” section.
KEY SWITCH
1. Remove control panel.
2. Remove two hex head screws supporting control panel brack-
et with 5/16" socket.
3. Pull bracket out and remove switch.
3. Remove screws from nut retainer.
4. Raise ram assembly slightly by hand and remove nut.
NOTE: Count the number of revolutions to spin off nut. TRUN-
NION must be reinstalled to same position.
5. Reinstall trunnion nut and retainer.
CONTINUAL STRIPPING OF TRUNNION NUT:
POSSIBLE CAUSES:
1. Incorrect assembly of trunnion assembly.
2. Transporting compactor incorrectly.
3. Burr on main drive screw; sharp edge on lead-in thread.
4. Upper limit switch adjustment.
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 cov-
ered 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 slid-
ing 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 le-
verage) 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.
UPPER LIMIT SWITCH
1. Remove drawer assembly.
2. Lower ram to gain access to switch.
3. Remove air scentry tray.
4. Remove hex head screw with 5/16" socket, pull switch down

two socket head cap screws that hold the gearbox to the
motor trunnion.
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.
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.
2. Use 13/16" wrench to remove bolts securing links to motor
trunnion.
When reinstalling, bolts torque 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.*
5. Tilt gearbox forward and remove chain. Lift gearbox out.
When installing gearbox, Locktite® should be applied to the
socket head cap screw nuts.
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 re-
maining sprocket, re-
move the drive pin
and then insert a
screwdriver through
the hole to provide a
means of keeping
the drive screw from
turning.
CHAIN
1. Turn sprocket until two holes in sprocket line up with socket
head cap screws.
2. Remove socket head cap screws and tip gearbox/motor as-
sembly to remove chain. 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.
When reinstalling socket head cap screws, be sure Locktite® is
applied to the nuts.
GREASING COMPACTOR
MECHANISM
1. Unplug compactor from wall outlet.
2. Remove drawer assembly from compactor.
3. Remove back of compactor and lower mechanism manually
by turning 5/8" nut on sprocket clockwise.
4. Line up one of the holes in the black sprocket with the hole
in the gearbox. Insert a 3/8" bolt or pin to keep sprocket from
turning and remove the 15/16" nut.
5. Slide off sprocket and washer.
6. Drive out the drive pin, slide off thin washer and pull out
trunnion bearing.
Chain Derailment: Loose chains. Sometimes a chain will derail be-
cause trash which flew up above the ram during compacting fouled the
chain. Newspaper or a paper bag should be placed on top of glass
bottles before compacting to prevent this.
If continual derailment of the chain is a problem, inspect both sprock-
ets for worn or missing teeth.
Inspect gearbox mounting and
mounting plate. If the mount-
ing screws are loose, gearbox
movement may be the cause. If
the gearbox mounting plate is
bent where it meets the motor
trunnion, eitherstraightenorre-
place the gearbox.
7. Grease trunnion bearing everywhere, inside and out, with
regular wheel bearing grease.
Somechainloosenessisnormal
and may increase as the com-
pactor is used. Seldom does the
chain “stretch” to the point
where it is too loose.
8. Reassemble unit in reverse procedure. When reinstalling 15/
16" nut, be sure to apply a drop of Locktite® or equivalent to
the threads of the 15/16" nut.
Apply grease to length of drive screw and a dab to the scissor
links at the pivot points.
MOTOR
Before motor is removed, it should be tested to be sure it is
inoperative. Check the continuity of the motor.
