GENERAL

The equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians.

The I-TEC must be installed with the Bard
manufactured IWS wall sleeve and ILG louver
grille accessories. These are sold as separate
accessories. Any substitutions will void the
manufacturer’s warranty.

The unit is designed for use with or without ductwork.
For use without ductwork, Plenum Box IPBDFZ18­color (18" height) or IPBDFZ12-color (12" height) is
recommended.

These instructions explain the recommended method
to install the air cooled self-contained unit and the
electrical connections to it.

These instructions and any instructions packaged
with any separate equipment required to make up the
entire heating and air conditioning system should be
carefully read before beginning the installation. Note
particularly “Start Procedure” and any tags and/or
labels attached to the equipment.

While these instructions are intended as a general
recommended guide, they do not supersede any national
and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation is
made. See Page 3 for information on codes and standards.

Size of unit for a proposed installation should be
based on heat loss or heat gain calculation made
according to methods of Air Conditioning Contractors
of America (ACCA). The air duct should be installed
in accordance with the Standards of the National Fire
Protection Systems of Other Than Residence Type,
NFPA No. 90A, and Residence Type Warm Air Heating
and Air Conditioning Systems, NFPA No. 90B. Where
local regulations are at a variance with instructions,
installer should adhere to local codes.

ANSI Z535.5 Denitions:

• Danger: Indicate[s] a hazardous situation which, if
not avoided, will result in death or serious injury. The
signal word “DANGER” is to be limited to the most
extreme situations. DANGER [signs] should not be used
for property damage hazards unless personal injury risk
appropriate to these levels is also involved.

• Warning: Indicate[s] a hazardous situation which,
if not avoided, could result in death or serious injury.
WARNING [signs] should not be used for property
damage hazards unless personal injury risk appropriate to
this level is also involved.

• Caution: Indicate[s] a hazardous situation which, if
not avoided, could result in minor or moderate injury.
CAUTION [signs] without a safety alert symbol may be
used to alert against unsafe practices that can result in
property damage only.

• Notice: [this header is] preferred to address practices
not related to personal injury. The safety alert symbol
shall not be used with this signal word. As an alternative
to “NOTICE” the word “CAUTION” without the safety
alert symbol may be used to indicate a message not
related to personal injury.

SHIPPING DAMAGE

Upon receipt of equipment, the unit should be checked
for external signs of shipping damage. The skid must
remain attached until the unit is ready for installation.
If damage is found, the receiving party must contact
the last carrier immediately, preferably in writing,
requesting inspection by the carrier’s agent.

UNIT REMOVAL FROM SKID

WARNING

This unit is heavy and requires more than one person
to handle during installation and removal from the
skid. Extreme caution must be taken to prevent injury
to personnel and damage to the unit. Use appropriate
safety equipment, including gloves when handling.
Failure to do so may result in serious injury.

A forklift or a lift rated for the load (Figure 2A) is
required to lift the unit off from the skid. This unit is
top heavy and should never be tipped while moving it.

The I-TEC is designed to be lifted off the skid from the
front or rear of the unit without having to remove any
doors or side panels. See Figure 1 for fork openings.
The shipping brackets on front and rear of the unit must
be removed and discarded. The unit can now be lifted
straight up and the skid can be slid out from underneath.

Tip unit from left side only.
Failure to do so may result in injury due to unit
top-heaviness or compressor damage!

HANDLING UNIT AFTER REMOVAL FROM SKID

If a wide and tall opening exists, the I-TEC can be moved as a
complete assembled unit. If not, use the following directions for
dis-assembly to allow it to pass through a 36" wide door.

1. Depress and release both top & bottom door latches and
open doors.

2. Remove doors by lifting straight up & off from the hinge pins.

3. Remove cabinet sides by rst removing the four (4) sheet metal

screws from the front (leading edge) of the side panel. The panel
will not fall off. Swing the panel away from the chassis 20-30
degrees & then pull forward from the two (2) tabs supporting
the rear edge. At this point, the unit can be tipped on its left
side enough to get dolly carts under it. Use dolly carts to
move unit into installation area. Use care not to damage
vent wire harness. This method is not suggested due to unit
weight and if a forklift or unit lift is available, continue with

the following steps for separation of top section & bottom base.

4. On each side of the unit is a tie plate that secures the top &
bottom sections with four (4) cap bolts. Using a ½" wrench
or socket, remove these screws from both plates & set aside.

5. If the unit is equipped with a CRV, you must unplug the
wire harness on the left-hand side of the control box.

6. A forklift or a lift rated for the load is required to lift the
top section off from the bottom base. Do not attempt to
do this manually! Failure to do so could result in the
unit tipping over & causing bodily injury &/or damage to
the unit.

7. The top section can be forked from either the RH or LH
side. See Figure 1 for fork openings.

8. Carefully lift the top section straight up avoiding tipping.

9. Move the top section through the doorway & place on at

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.

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 nal 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 toward you;
there are no screws securing it in place. Both the top and
bottom slide toward you 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 xed ceiling for ducted applications is 9 ft. 7 in.

This provides enough clearance to install the duct work.
See Figure 5A.

The IWS Series wall sleeve has a built-in vertical

adjustment to t window sill heights from 31-34 inches.

If additional height is required, two riser platform
accessories are available. The IRZ3 increases the
unit height by 3 inches (Figure 5B) and the IRZ6 by 6
inches (Figure 5C).

Several construction options are available for unit

installation of the IZ Series. Serviceability and lter

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 eld 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 SECTION VIEW (Page 10) for locating this top
wall bracket which will need to be applied after the unit is

located in the nal 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 lters (uppermost set)

• removing the compressor section service door (lower set)

• removing vent door and vent partitions (base 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.

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 oor ush with wall and

centered over wall opening.
