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 SET FOR HOME APPLIANCES.
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. Viking Range
Corporation cannot be responsible, or assume any liability, for injury or damage of any kind arising
from the use of this manual.
Grounding Instructions
FOR PERSONAL SAFETY, THIS APPLIANCE MUST BE PROPERLY GROUNDED.
This power cord on this appliance is equipped with a three-prong (grounding) plug which mates with a
standard three-prong (grounded) receptacle.
If there is a two-prong outlet located where you will install the compactor, it is your responsibility to have
it replaced with a properly grounded three-prong wall receptacle.
DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR REMOVE THE THIRD (GROUND) PRONG FROM
THE POWER CORD.
A 120-volt, 60 Hz., A.C., 15 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 WITH THIS APPLIANCE.

SAVE THESE INSTRUCTIONS
REVIEW ALL SERVICE INFORMATION IN THE APPROPRIATE SERVICE MANUAL AND
TECHNICAL SHEETS BEFORE BEGINNING REPAIRS.
Pride and workmanship go into every product to provide our customers with quality products. It is possible, how-
ever, that during its lifetime, a product may require service. Products should be serviced only by a qualied service
technician that is familiar with the safety procedures required in the repair and who is equipped with the proper
tools, parts, testing instruments, and the appropriate service manual.
Safety Information
We have provided many important safety messages in this
manual and on the appliance. ALWAYS read and obey all
safety messages. This is the safety alert symbol.
This symbol alerts you to hazards that can kill or hurt you
and others. All safety messages will be preceded by the
safety alert symbol and the word “DANGER”, “WARNING”, or
“CAUTION”. These words mean:
All safety messages will identify the hazard, tell you
how to reduce the chance of injury, and tell you
what can happen if the instructions are not followed.

Safe Servicing Practices

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.
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 o 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.
