WARNING
Safety Hazard!
Failure to follow instructions below could result in
death or serious injury and equipment or property
damage.
For continued performance, reliability, and safety, use
only accessories and replacement parts approved by
the manufacturer. Using parts and accessories not
approved by the manufacturer may void the
equipment's limited warranty and could lead to risk of
fire, equipment malfunctions, and failures. Refer to
the manufacturer's instructions and replacement part
catalogs provided by your equipment supplier.
WARNING
Electrical Shock, Fire, or Explosion
Hazard!
Failure to follow these instructions could result in
serious injury, death, or property damage.
• Ensure proper servicing of the unit.
• Disconnect all electrical power to furnace
before servicing.
• Label all wires prior to disconnecting when
servicing controls. Reconnect wires correctly.
• Verify proper operation after servicing.
WARNING
Safety Precautions!
Failure to follow the safety precautions could result in
serious injury, death, or property damage.
• Follow instructions according to the controlled
procedures to minimize the risk of the presence of
flammable gases or vapors while working.
• Do not work in confined spaces. All maintenance
staff and others working in the local area must be
instructed on the nature of work.
• Check the area with an appropriate refrigerant
detector prior to and during work to ensure the
technician is aware of potentially toxic or flammable
environment.
• Keep dry powder or CO

fire extinguisher adjacent
to the charging area. Appropriate fire extinguishing
equipment must be available and easily accessible if
any hot work is conducted on the refrigerating
equipment or any associated parts.
• When handling work related to refrigerating
system that involves exposing any pipe work, do not
use any sources of ignition that may lead to the risk of
fire or explosion. All ignition sources should be kept
sufficiently far away from the site of installation,
repair, or removal and disposal of the unit, during
which refrigerant can possibly be released into the
surrounding space.
• Prior to beginning work, the area around the
equipment must be supervised to confirm there are
no flammable hazards or ignition risks. No Smoking
signs must be clearly displayed.
• Ensure that the area is in the open or that it is
adequately ventilated before opening the system or
conducting any hot work. A continous ventilation
must exist during the course of work that safely
disperses any released refrigerant and expels it
externally.
