Safety Information/Warnings
2.1 Safety Information and Warnings
Every practical safety feature has been incorporated into the design and manufacture of
the Thrush Co. Aar-O-Vent. If questions are not answered by this manual, or if specific
installation, operation, and/or maintenance procedures are not clearly understood,
contact your local representative before proceeding. Personnel must, at all times,
observe all safety regulations while performing maintenance or repairs.
All installation, operation, and maintenance procedures should be performed by
qualified, experienced and well trained personnel. The potential exists for severe
personal injury if proper procedures are not followed.
Depending on the size of Aar-O-Vent, the bundle can be quite heavy. It is
recommended that supports be used when removing the head and bundle. Once
all bolts have been removed from the head, the head and bundle are free to drop.
Risk of severe personal injury and/or property damage may occur if the bundle
and head are not supported.
5” and larger Aar-O-Vents have lift lugs to aid in lifting and locating the unit. The
lift lugs are not intended to be used to support the Aar-O-Vent during operation.
Adequately sized and spaced supports/hangers should be used to prevent
damage or strain on the system piping.
The Aar-O-Vent is not designed to be used as a make-up water inlet point. Using
any of the connections for make-up water would impede proper operation and
void the warranty.
System water over 100°F can be very hazardous. Keep flow away from the body
when flushing the unit. Failure to do so could result in serious bodily injury or
property damage.
