ANSI Z535.5 DEFINITIONS

• DANGER – 

Indicate[s] a hazardous 

situation which, if not avoided, will 
result in death or serious injury.

• WARNING

 

–

 Indicate[s] a hazardous 

situation which, if not avoided, could 
result in death or serious injury.

• CAUTION

 

–

 Indicate[s] a hazardous 

situation which, if not avoided, could 
result in minor or moderate injury.

• NOTICE –

 

Not related to personal injury

 

–

 

Indicates[s] situations, which if not avoided, 
could result in damage to equipment.

Do NOT remove shipping crate until 

the merchandiser is positioned for 

installation.

Excessive ambient conditions may 
cause condensation and therefore 
sweating of doors. Facility operators 
should monitor doors and floor 
conditions to ensure safety of persons.

Adjust closing torque by turning the bottom

hinge pin in the direction the door closes.  

Use a 1/2 inch (13 mm) wrench, and turn 
the hinge pin until the door closes on its own.

Usually it takes two clicks or a half turn.
