Follow these steps to install the articulated arm, as shown in
fig. 4.3.3a
through
4.3.3d
:
•
Bolt mounting bracket (A) to wall or steel column; to
ensure a level mounting, level to the pivot pin on the wall
bracket, and not the edge of the steel plate.
•
If included, mount the fan (B) with a MB-FUA-C1/C2
bracket (also referred to as the FUK bracket).
•
Mount the extractor arm (C). Tighten to torque values
noted in the table above.
•
Set friction by tightening the bolt at swivel joint, until the
arm remains in one position; this is done while attaching
the reel and duct (D).
•
Mount hose reel to boom arm.
•
Mount spiro-tubing and hose on the boom arm (E).
•
Mount ducting bend to hose reel, then mount the hose to
the ducting bend (F).
•
Readjust friction as needed (G).

4.3.4 Factory-installed mechanical damper
Based on the facility design requirements, a sealed closing
damper, as shown in
fig. 4.3.4
, may have been factory
installed on the duct portion of the hose reel. In a facility that
includes multiple hose reels, this
built-in mechanical damper allows
airflow only through hose reels
currently in use, reducing energy
costs. The damper opens
automatically when the hose is
lowered (2 rotations), and closes
when the hose is raised by the
operator.
This damper is typically used when
there are no other dampers
installed in the duct work, and no
electronic control units are being
installed.
