8.3 Arm and wall/post bracket installation (hanging type,
no exhaust fan)
The installation crew must ensure the arm/bracket assembly is installed
within the arm reach of the area where source capture has to be
performed. The arm bracket must be installed on a wall, post or any
other structure capable of supporting weight of the arm and optional
equipment.
Note on arms equipped with recoil telescopic springs :
Do not attach
spring assembly from socket tube spring bracket to rotating socket before
step # 4 is completed.
1.
Install bracket on support structure at proper height for arm length.
Fasteners to support structure are not supplied. Arm bracket can
also be welded to structure if allowed or permitted.
2 .
The duct flange is inserted from underneath the arm support
bracket into the bracket outlet. The fume arm socket will hold the
duct flange into position.
Note before installing 5" 6" and 8" diameter fume arms :
The
rotating arm socket has a stopper which consists of a socket set
screw bolted on the male part of the socket and a "tooth" on the
female part blocking the arm from doing a full 360 degrees rotation.
If the arm bracket is installed on a wall or a column, ensure the
"tooth" is facing the wall or the column. 3" and 4" arms are able to
rotate 360 degrees and do not have a stopper.
3 .
Lift MAXAIR fume arm into position and align both arm and bracket
bolt patterns.
4 .
Using the fasteners provided, attach the arm onto the support
bracket. Ensure the duct flange is centered with the bracket oultet.
Before proceeding to the next step, push the arm left and then right
to ensure the socket rotates freely.
Do not remove spring tube stopper.
