REQUIRED STEPS AFTER FINAL
PLACEMENT
The compressor is secured to the base with two (2)
bolts for shipping. Although the unit will perform as
designed with the shipping bolts in place, there may
be noticeable additional noise and vibration noted. To
obtain the lowest noise and vibration levels, remove
the shipping bolts after the unit is in its final operating
location. To gain access to the compressor, the
compressor access panel must be removed (Figure 7).
Once this panel is removed, the CRV air duct must be
removed. See Figure 4.
The air duct is removed by pulling it straight out;
there are no screws securing it in place. Both the top
and bottom slide at the same time (
pull hard
). Once
removed, the compressor is visible as well as the tags
on the shipping bolts (Figure 3).
After the compressor shipping bolts have been
removed, the CRV air duct can be slid back in place
and the compressor access panel attached.
MINIMUM INSTALLATION CLEARANCES
The minimum installation height to the bottom of
the roof or fixed ceiling for ducted applications is 9'
7". This provides enough clearance to install the duct
work. See Figure 5A.
The IWS Series wall sleeve has a built-in vertical
adjustment to fit window sill heights from 31-34".
If additional height is required, two riser platform
accessories are available. The IRZ3 increases the unit
height by 3" (Figure 5B) and the IRZ6 by 6" (Figure
5C).
Several construction options are available for unit
installation of the IZ Series. Serviceability and filter
access must be considered before installing. See
Figure 5D for required clearances and recommended
service access dimensions.
SECURING UNIT TO STRUCTURE
Shipped with the I-TEC unit is a wall mounting bracket
(screwed to shipping skid on backside of unit). This
bracket can be utilized to secure the top portion of the
unit to the wall using the appropriate field-supplied
hardware based upon the material being fastened to.
(There are several offset holes, sized to accept up to a
1/4" diameter fastener, that will easily allow studs to be
hit on a framed wall.)
See
Bracket Wall Section View
for locating this top wall bracket which will need to be
applied after the unit is located in the final position.
Additional/optional mounting holes for up to a 3/8"
diameter fastener are also available in the backside and
base of the unit. These can be accessed by:
• removing the air filters (uppermost set)
• removing the compressor section service door (lower
set)
• removing vent door and vent partitions (base set)
Refer to
Wood Framed Installation
for additional
framing required to secure unit to wall.
The additional/optional mounting holes will require a
long extension to drive the fasteners.
SEISMIC CONSIDERATIONS
The I-TEC product features several locations for
product securement but all site conditions are
different. Consult with a licensed Seismic Engineer
to advise of particular needs when attaching the I-TEC
unit to the structure.
RUBBER MAT
Unit rests on rubber mat placed under base rails during
installation. Place mat on floor flush with wall and
centered over wall opening.
