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 a 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 (see Figure
5 on page 13). Once this panel is removed, the CRV/
ERV air duct must be removed (see Figure 5).
The air duct is removed by pulling it straight out; there
are no screws securing it in place. Both the top and
bottom will slide out at the same time (
pull hard
).
Once removed, the compressor is visible as well as the
tags on the shipping bolts (see Figure 6 on page 13).
After the compressor shipping bolts have been
removed, the CRV/ERV air duct can be slid back in
place and the compressor access panel re-attached.
MINIMUM INSTALLATION HEIGHT
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 7A on page 14.
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 IRP3 increases the unit
height by 3" (Figure 7B on page 15) and the IRP6 by
6" (Figure 7C on page 16).
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 you are fastening
to.
(There are several offset holes, sized to accept up
to a 1/4" diameter fastener that will easily allow you
to hit studs on a framed wall.)
See
BRACKET WALL
SECTION VIEW
(page 10) 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 of
the unit. These can be accessed by:
• removing the air filters for the uppermost set
• removing the compressor section service door for
the lower set
Refer to
WOOD FRAMED INSTALLATION
(page 10) for
additional framing required to secure unit to wall.
The additional/optional mounting holes will require a
long extension to drive the fasteners.
9. Move the top section through the doorway and
place on flat surface free of debris.
10. The bottom base can now be moved through the
doorway the same way.
11. Reassemble the unit by reversing this procedure.
