TOOLS REQUIRED:
1. Power Screwdriver
• Phillips #3 Bit - oor panel screws
• Phillips #2 Bit - grille trim ring screws
2. Panel Lifter (Suction Cups) - remove oor panel
3. Jigsaw - cut opening in oor panel (if panels are not pre-cut)
4. Carpet Knife - cut opening in carpet tile / oor covering
MATERIALS REQUIRED:
1. MIT3-CN Underoor Air Distribution Terminal
2. Plug & Play Cable (PAP-1)
3. #8 – 32 x 1-1/2" (38.1mm) Self-Drilling/Tapping Sheet Metal
Screws (1-1/2" screws work in most applications; using other
screws could void warranty)
PREPARATION:
1. Verify that MIT3-CN is the correct model, unit count and
location(s) per scheduled placement.
2. Remove oor covering (carpet tile) / oor panel at desired
location(s) (if installed).
3. Verify that all adjacent oor panels are properly installed.
INSTALLATION:
The MIT3-CN is designed to be installed into a oor panel that
has been removed from the oor. The completed assembly is
then installed back into the oor and connected to a designated
VAV operational zone with Plug & Play Cables.
If the oor panel / carpet tile was installed with a 10-1/2" x 5-1/2"
[+1/8"/-0"] (267mm x 140mm [+3.175/-.00]) rectangle hole pre-cut,
skip to Step 2. If the unit is being added to an existing installation,
begin with Step 1.
IMPORTANT: It is HIGHLY RECOMMENDED by the
manufacturer that each zone be checked for faulty
or improper wiring DURING INSTALLATION. Each
zone should be tested thorougly for full connectivity
before proceeding with installation of the next
zone. The manufacturer cannot be responsible for
any improper installation as a result of failure to
follow this procedure as outlined in the FlexSys
Connectivity Testing Procedures.

INSTALLATION (CONTINUED):
1. Remove oor panel and cut 10-1/2" x 5-1/2" [+1/8"/-0"]
(267mm x 140mm [+3.175/-.00]) rectangle opening for MIT
terminal. Cut opening in carpet tile using same dimensions /
position.
NOTE: Floor panels with pre-cut openings may be
supplied by ooring manufacturer.
2. Remove trim ring and grille insert from MIT terminal. Remove
package of trim ring screws from interior of terminal (screws
may be provided in a separate box on shipping pallet).
3. Set MIT terminal on work surface. Lay oor panel on top of
terminal, so that rectangle collar ts through pre-cut opening.
Place carpet tile in position on top of oor panel.
4. Insert trim ring into MIT terminal.
IMPORTANT: Align trim ring screw holes with
corresponding holes on sides of rectangle collar.
5. Secure trim ring to MIT terminal, using included screws to
hold assembly together.
6. Replace oor panel (with installed MIT terminal / trim ring).
Orient panel so that air valve opening is directed away from
exterior walls.
7. Connect MIT terminal to designated VAV operational zone,
using Plug & Play Cables connected to molex inputs located
on air valve actuator.
8. Conrm air valve operation – spin damper by hand to verify
it is free to move. Incorrect routing of cables and other
underoor obstructions can interfere with operation.
9. Replace oor panel screws to secure oor panel / MIT
assembly in place.
10. Place grille insert into trim ring in desired orientation.
OPTIONAL: Tighten security screws (if provided).
11. For protection of diffuser grille nish during construction,
a Grille Cover is recommended.
Use only #8 Phillips Head Sheet Metal Screws.
Using other screws could void warranty.
