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. Never interfere with the proper operation of any safety device.
4. USE ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE. SUBSTITUTIONS MAY
DEFEAT COMPLIANCE WITH SAFETY STANDARDS.
5. GROUNDING: The standard color coding for safety ground wires is GREEN, or GREEN WITH
YELLOW STRIPES. Ground leads are not to be used as current-carrying conductors. It is EXTREMELY
important that the service technician re-establish all safety grounds prior to completion of service.
Failure to do so will create a hazard.
6. Prior to returning the product to service, ensure that:
• All electrical connections are correct and secure
• All electrical leads are properly dressed and secured away from sharp edges, high-temperature
components, and moving parts
• All non-insulated electrical terminals, connectors, heaters, etc., are adequately spaced away from
all metal parts and panels
• All safety grounds (both internal and external) are correctly and securely connected
• All panels are properly and securely re-assembled
NOTE
This service manual is intended for use by persons having electrical and mechanical training and
a level of knowledge of these subjects considered acceptable in the appliance repair trade.
DISPERATOR cannot be responsible, or assume any liability, for injury or damage of any kind
arising from the use of this manual.
Grounding Instructions
IMPORTANT: TO REDUCE THE RISK OF ELECTRIC SHOCK - PLEASE READ CAREFULLY.
FOR PERSONAL SAFETY, THIS APPLIANCE MUST BE PROPERLY GROUNDED.
IF THERE IS ANY DOUBT AS TO WHETHER THE WALL RECEPTACLE IS PROPERLY GROUNDED,
HAVE IT CHECKED AND PROPERLY GROUNDED BY A QUALIFIED ELECTRICIAN.
A 220-240 volt, 50-60 Hz., A.C., 10 amp fused and grounded electrical supply is required (time-delay
fuse or circuit breaker is recommended). It is recommended that a SEPARATE CIRCUIT serving only this
appliance be provided.
DO NOT USE AN EXTENSION CORD OR PLUG ADAPTER WITH THIS APPLIANCE.

How the compactor works
The compactor compresses kitchen trash up to 1/6 of its original volume. It will compact normal kitchen trash
including cartons, glass and plastic bottles, containers and jars, tin cans, wrappings, boxes etc.
When you start the compactor, an electrically powered ram moves down into the trash bucket, compresses the
trash and then returns to the “UP” position and shuts off automatically.
NOTE: The ram travels about 2/3 of the way down into the trash bucket. Because of this, the trash bucket must be
at least 1/3 full before you will notice any compression.

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 built-in 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.
CAUTION
Failure to use Toe Kick Assembly Kit Model 15TCTK
in a free-standing installation may cause the
compactor to be unstable during operation.
Section A – Installation
Built-in Installation
MOUNTING STRAPS
Two under-counter mounting straps are provided. Use
these straps to secure the compactor to the underside
of a countertop.
Fasten the slotted end of the straps to the compactor
using the holes in the top of the compactor cabinet as
shown.
NOTE: When installation compactor under granite or
solid surface countertops, bend the mounting straps
so they can be secured to the adjacent cabinetry.
UNDER-COUNTER OPENING
The compactor requires an under-counter opening 15-in.
wide, 34-1/2-in. high, and 22-in. deep.
Plan to provide an electrical outlet in the opening that
meets all applicable electrical codes and requirements.
See “Grounding Instructions” on Page 2 for specific
information.

Section A – Installation
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.
Leveling the Compactor
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.
To level the back of the compactor:
Tip the back of compactor up and onto a wood block.
Loosen the adjusting screws only far enough to move
the rollers to a higher or lower slot. Retighten the ad-
justing screws and remove the wood block.
To level the front of the compactor:
Tip the front of compactor up and onto a wood block.
Turn the leveling legs in or out to the desired position.
Remove the wood block.
