DESCRIPTION AND USAGE
The ECM motor simulator is designed to assist the service
technician in troubleshooting the variable speed gas-fired
furnaces. Use the procedure outlined below to troubleshoot with
the ECM motor simulator.
Installing and servicing heating equipment can be hazardous due
to gas and electrical components. Only trained and qualified
service personnel should install, repair, or service heating
equipment.
Untrained personnel can perform basic maintenance functions
such as cleaning coils, or cleaning and replacing filters. All other
operations should be performed by trained service personnel.
When working on heating equipment, observe precautions in
literature, on tags, and on labels attached to or shipped with the
unit, and other safety precautions that may apply.
Follow all safety codes. In the United States, follow all safety
codes including the National Fuel Gas Code (NFGC) NFPA
54/ANSI Z223.1. In Canada, refer to the National Standard of
Canada Natural Gas and Propane Installation Codes
(NSCNGPIC), CSA B149.1.
Wear safety glasses and work gloves. Have a fire extinguisher
available during start-up, adjustment procedures, and service
calls.
Recognize safety information. This is the safety-alert symbol
AX. When you see this symbol on the furnace and in instructions
or manuals, be alert to the potential for personal injury.
Understand the signal words DANGER, WARNING,
CAUTION, and NOTE. The words DANGER, WARNING, and
CAUTION are used with the safety-alert symbol. DANGER
identifies the most serious hazards which will result in severe
personal injury or death. WARNING signifies hazards which
could result in personal injury or death. CAUTION is used to
identify unsafe practices which may result in minor personal
injury, or product and property damage. NOTE is used to
highlight suggestions which will result in enhanced installation,
reliability, or operation.
