DID301-302 Installation, Operation & Maintenance Manual (USA) (06/2015)
3.1 General procedure
Chilled beams should be mounted and connected prior to installing
the suspended ceiling or drywall. The unit should be installed in the
location shown on the design drawings. Deviation from the designed
mounting position should be avoided as the chilled beam location in
relation to the room walls and other chilled beams is critical to the
comfort of the conditioned space.
The chilled beam leaves the
factory with low tack film
applied to the face (see
photo) to protect the painted
surface. Film should remain
on beam during installation.
Remove the film before the
air system is started.
3.2 Installation considerations
3.3 Hanging the chilled beam (by Mechanical Contractor)
STEP ONE —
•
Determine beam locations according to design drawings.
•
Fix anchors (type dependant on building design and determined
by others) into the structure above the chilled beam mounting
location.
STEP TWO —
The beam should be suspended 3” above the finished ceiling
elevation using building code approved threaded rods (recom-
mended) or wires. The rod or wire (both provided by others) allow
the beam’s vertical height to be adjusted so that the beam can be
lowered into the ceiling grid with which it is to be integrated.
It is recommended that the unit be suspended from
linear channels
to provide adjustability in every direction.
The unit is provided with
sliding hanging brackets
that allow for
adjustment along the length and width of the beam (both shown
here):
Guidelines when using rods
Install Unistrut with appropriate support to carry
the beam
Fasten studs to Unistrut with Unistrut nut in proper
location above the beam’s hanging brackets
Adjust beam as needed to final hanging location
Guidelines when using Wire
Distribute sliding brackets evenly spaced along the sliding rail on
the plenum box of the beam
Wire should be looped through and around the
inside
of the
bracket
Wires should run from the bracket straight up or slightly away from
the beam to the anchor location.
Suspension device requirements
Chilled beams up to 6 ft in length should be supported by a
minimum of four (4) suspension devices. Chilled beams above 6 ft
in length must be supported by a minimum of six (6) suspension
devices.
Installation Example
Sliding Hanging Bracket
Rail System
Warning!
Each unit must be supported independently from the sus-
pended ceiling. The fixing points should only carry the
weight of the chilled beam. Separate supports should be
provided for adjacent systems components.
Note
It is recommended that chilled beams be installed
using flexible hoses.
If hard connections are used, the connections
should be made after the chilled beam is
lowered into the ceiling grid and is in its final
position.
Warning!
The hanging wire should NEVER angle across the beam
as it will put undue stress on the sliding bracket and rail.
