Safety Information
IMPORTANT SAFETY
INSTRUCTIONS
WARNING
Risk of a lack of oxygen.
• Vehicle exhaust gases contain carbon
monoxide.
• Refrigerant gas can displace air in work
area.
Use your
1090AT diagnostic™ unit in
locations with mechanical ventilation
providing at least four air changes per
hour.
Impairment of breathing can cause injury.
Power
WARNING
Risk of electric shock and fire.
• To avoid electric shock the power cord
protective grounding conductor must
be connected to a properly grounded
A.C. outlet.
• Use proper A.C. outlet for unit to
operate correctly. See unit ID plate on
back of unit. Extension cords are not
recommended. If an extension cord is
necessary, then use:
— 16 AWG for cords up to 50 feet
long, and
— 14 AWG for cords greater than 50
feet but less than 100 feet long.
• Connect power cord to properly
grounded outlet.
• Do not remove or bypass the
grounding pin.
• Do not use on wet surfaces or expose
to rain.
• Use only fuses with the rating
specified near the fuse holder.
Electric shock and fire can cause injury.
Refrigerant
WARNING
Risk of expelling refrigerant under pressure.
• Wear safety goggles and protective
gloves, user and bystander. Everyday
eyeglasses only have impact resistant
lenses, they are NOT safety glasses. If
any refrigerant gets into eyes, flush
with water and seek a doctor's aid
immediately, even though irritation
may cease.
• Do not remove master filter/dryer while
under pressure. Perform maintenance
procedure for removing master
filter/dryer, refer to
Changing the
Master Filter/Dryer.
• Prevent refrigerant from contacting the
skin.
Expelled refrigerant can cause injury.
WARNING
Risk of explosion.
• Do not use compressed shop air for
leak detection or to pressure test a
system containing refrigerant.
Refrigerant can form combustible
mixtures at pressures above
atmospheric and with air
concentrations greater than 60% by
volume.
• Do not heat a container of refrigerant
above 125°F (52°C).
Explosion can cause injury.
WARNING
Risk of fire.
• Do not use this equipment in the
vicinity of spilled or opened containers
of gasoline.
• Do not use your
1090AT diagnostic™
unit or leak detector equipment if R-12
substitutes are suspected. R-12
refrigerant substitutes may be
flammable.
Fire can cause injury.
