Unpacking the Equipment 1.
Before beginning installation, check the overall condition of the equipment. Remove packing materials, and examine all
components for signs of shipping damage. Any shipping damage is the customer’s responsibility and should be reported
immediately to your freight carrier.
The Munters CSI24 Continuous Sidewall Inlet is a 24"H. door that can be continuous for a total of 150'L. and can be
mounted flush to the wall or offset so the drive pipe can be mounted away from the wall to avoid columns or posts. It
can also use either Straight Racks or Curved Racks. The CSI24 Continuous Sidewall Inlet is sold in 100' Door Kits and
10' Door Kits, an Ending Kit and the Actuator (actuator sold separately). For example: For a system that is 450'L.
with Offset Mount and Straight Racks, operated by 3 Actuators, the customer would receive the following:
(4) CSI24100SF, (5) CSI2410SF, (3) AC2872 and (3) Actuators (actuator sold separately).

Step 1A
The CS2410SF was designed for the door to be installed in the room and the Actuator and Pipe Drive system
be mounted in the hallway. Construct the framed opening to correct size according to Chart A (below) and
your CSI24 Continuous Sidewall Inlet size. See Chart A. If installing 2 or more sections of CSI24 doors,
be sure to leave 24" minimum between each framed opening.
See Figure 1A . Use Treated 2x6's for the
Framing.

Step 1B
On the hallway side of the framing, install a treated 2x4, 18" from the end framing and then every 10'-0"
O.C. down the length of the framing with the last 2x4 being 18" from the opposite end framing. These 2x4's
should span the top and bottom framing. Also, install double treated 2x6's on the end of the framed opening
to be used to moun the LA actuator to. See Figure 1B .

Step 2
After the Framed Openings are completed, make sure the surface of the 2x lumber is clean and free from
debris. The P-Shaped Foam Seal [4], comes in 60" lengths. Starting at 2" from the inside edge of the End
Framing, so that it will overlap the side Foam Seal, peal the back from the adhesive on the back of the Foam
Seal and affix to the framing with the top of the "P" flush with the top of the framing. See Figure 2A and 2B.
For the Foam Seal on the End Framing, the top of the "P" should be flush with the inside edge of the framing
and should run from the inside edge of the Top Framing to the bottom of the Foam Seal on the next frame
member. See Figure 2A and 2B.
Step 3
Continue attaching the P-Shaped Foam Seal until there is Foam Seal attached to 3 sides of each Framed
Opening. Once the Foam Seal is completely attached, go back and permanently attach to the framing
using Staples or Nails in the nailing grove of the Foam Seal Flap. Staples or Nails are not provided and
should be spaced every 4" -- 6". See Figure 2A and 2B.

Step 4
Each CSI24 Inlet system that is 30'L. or longer consists of (1) Left Door, (1 or more) Middle Doors and
(1) Right Door. The number of Middle Doors depends on the length of the run of CSI24 Doors. For example,
if the run of CSI24 Doors is 40'L. then there is (1) Left Door, (2) Middle Doors and (1) Right Door. If the run
is 100'L. then there is (1) Left Door, (8) Middle Doors and (1) Right Door. In the next steps all the doors will
be assembled before installing them to the framed openings. See Figure 3. If the run is only 20'L. then there
is only the Left Door and the Right Door.
