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 IPBDFZ18-
color (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.

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

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 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.

DUCT WORK
Any heat pump is more critical of proper operating
charge and an adequate duct system than a straight air
conditioning unit. All duct work must be properly sized
for the design airow requirement of the equipment.
Air Conditioning Contractors of America (ACCA) is
an excellent guide to proper sizing. All duct work or
portions thereof not in the conditioned space should be
properly insulated in order to both conserve energy and
prevent condensation or moisture damage. When duct
runs through unheated spaces, it should be insulated
with a minimum of one inch of insulation. Use
insulation with a vapor barrier on the outside of the
insulation. Flexible joints should be used to connect the
duct work to the equipment in order to keep the noise
transmission to a minimum.
The I-TEC series heat pump has provision to attach a
supply air duct to the top of the unit. Duct connection
size is 20 inches x 24 inches. The anges are shipped
at and must be bent upward using sheet metal anging
pliers. The duct work is eld supplied. See Figure 6 for
suggested attachment method.
Make sure to seal the slots in the bend-up ange at the
time of securing your ductwork to the ange. This can
be accomplished with either foil tape or caulk. Failing
to do so may cause air leakage/whistling of air.
NOTE: Unit cabinet, supply air duct and duct free
plenum are approved for “0” clearance to
combustible material.
The I-TEC series heat pumps are designed for use with
free return (non-ducted) and either duct free with the use
of IPBDFZ Series Plenum Box (18" or 12") or a duct
supply air system.
The IPBDZ Plenum Box mounts on top of the unit and
has both vertically and horizontally adjustable louvers on
the front discharge grille.
When used with a ducted supply, a Cabinet Extension
may be used to conceal the ductwork above the unit to
the ceiling. The ICX28 extends 28" above the unit for a
total height of 10'-2" or can be trimmed to any height.
The unit is equipped with a variable speed indoor
blower motor which increases in speed with an increase
in duct static pressure. The unit will therefore deliver
proper rated airow up to the maximum ESP shown
in Table 1A. However, for quiet operation of the
air system, the duct static should be kept as low as
practical, within the guidelines of good duct design.
FILTERS
Two 2-inch throw away lters (24 x 30) and two 1-inch
throw away lters (16 x 25) are supplied with each
unit. The 2-inch lters slide into brackets on both sides
for the return air openings. If a CRV vent option is
used, there are two (2) additional 1" throw away lters
included with that option. See Figure 7 for specic
locations. The lters are serviced from the inside of
the building by opening the cabinet doors, and do not
require any tools to access.

CONDENSATE DRAIN
There are two condensate drain connections from the
condenser drain pan (compressor area). These are
visible from the rear of the unit. Factory installed tubing
connects the two drains at a tee connection and then a
single drain hose with a barbed hose connector carries
the condensate to the draining option of your choice.
Enough tubing is provided to reach all drain options and
can be cut down in length.
The unit is shipped from the factory with the drain line
on the left-hand side as you look at the rear of the unit.
The tubing can be removed from the drain connections
and ipped for a right-hand drain. See Figure 8.
The drain can be routed directly through the oor or
through the wall. There are also two optional drain
locations in the lower rear back panel. See Figure 8.
The I-TEC design does not require a trap in the
condensate disposal tubing. Check your local codes to
see if a “P” trap is required.
For a stand pipe oor drain or through the wall, there is
adequate hose length to reach needed location behind the
unit. The lower rear portion of the cabinet is recessed
approximately 4 inches allowing room for a “P” trap (if
required) to be installed with the cabinet ush with the wall.
Keep in mind, the drain line must be able to be removed
from the unit if necessary to remove the unit from the wall.
Access plates are located on the rear of the unit for
servicing the drain trap. See Figure 8. If the drain line
is to be routed through an unconditioned space, it must
be protected from freezing.
The condensate drain line can also be routed back into
the unit through either the right-hand or left-hand
optional drain locations on the rear of the unit. The
hole is covered by insulation on the inside of the unit
and will have to be cut away. Located inside the unit,
about 12 inches in from the front on both the left and
right side are drain holes in the bottom of the base.
These holes are covered with insulation and are not
visible from inside vent option area. They are located
very close to the side panels and can be found by
pressing down on the insulation or looking at back of
vent option area (See Figure 8). Cut insulation away
to expose the hole. A drain trap can now be installed
inside of the cabinet, and the drain hose routed directly
through the oor.
Once the I-TEC is installed, the rear drains exiting the
condenser section can be easily serviced with removal
of the pre-painted metal sides (lift-off doors, remove
four [4] screws to remove side).
If side access is not available, the drain lines and trap
can be serviced by removing either one of the drain
access panels on the rear of the unit (in the ventialtion
package area.) See Figure 8.
After drain installation is complete, drain area must
be insulated for sound purposes with 45" x 24
¾" x 6"
piece of insulation. See Figure 8.
WITH NO VENT OPTION
To remove the drain access panels in the rear of this
section, simply remove the front door/cover from the
box. Rear drain access panels are now visible on both
right-hand and left-hand sides in rear of box.
WITH COMMERCIAL ROOM VENTILATOR
1. Open hinged front doors.
2. Disconnect unit power to eliminate shock hazard.
3. Remove front cover/door of CRV vent package.
(Can leave lter access panels in place.)
4. Unplug wires coming in on left side from upper
unit section.
5. Unplug two wire harness from front (intake) blower.
6. Remove two (2) screws securing front (intake)
blower and slide blower out of unit.
7. Remove four (4) screws that retian the partition
behind/beneath intake blower removed in Step #6.
8. Rear drain access panels are now visible on both
right-hand and left-hand sides in rear of box.

MOUNTING THE UNIT
The wall sleeve is attached to the I-TEC unit from the
outside of the building. See Figures 9A & 9B. Refer
to wall sleeve Manual 2100-562 supplied with sleeve.
Following are the steps for attaching the I-TEC to the
wall sleeve.
1. Lift the unit into place making sure that it is
aligned side to side. Align unit with rubber mat.
2. Push the unit back until the rear panel touches
the sleeve gasket.
3. This unit must be level from side to side and
from front to back. If adjustments are necessary,
shim up under the base rails with sheets of metal
or any substance not affected by moisture.
4. Attach the sleeve to the unit using the ten (10) ¾"
long self-tapping screws supplied with the sleeve.
5. Theexhaustsleevehasthree(3)¾"longscrewslots
in each side ange. Line these up with the screw
engagement holes in the fan panel. Attach using six
(6) ¾" long pointed sheet metal screws supplied
with the sleeve. Extend the sleeve out until it is
ush with the louver grill attachment angles.
6. Lock the sleeve in place using two (2) ½" long
pointed sheet metal screws on each side by
shooting through the slot into a pre-punched hole.
7. A bottom trim piece is shipped loose for
installation beneath the doors. Attach the trim
piece to the unit with screws provided.
8. The compressor is secured to the base with two
(2) bolts for shipping. Both bolts are identied
with a tag. Remove shipping bolts (Figure 3).
WIRING – MAIN POWER
Refer to the unit rating plate and/or Table 2 for wire sizing
information and maximum fuse or “HACR Type” circuit
breaker size. Each unit is marked with a “Minimum Circuit
Ampacity”. This means that the eld wiring used must be
sized to carry that amount of current. Depending on the
installed KW of electric heat, there may be two eld power
circuits required. If this is the case, the unit serial plate will
so indicate. All models are suitable only for connection
with copper wire. Each unit and/or wiring diagram will be
marked “Use Copper Conductors Only suitable for at least
75°C”. THESE INSTRUCTIONS MUST BE ADHERED
TO. Refer to the National Electrical Code (NEC) for
complete current carrying capacity data on the various
insulation grades of wiring material. All wiring must
conform to NEC and all local codes.
The electrical data lists fuse and wire sizes (75°C copper)
for all models, including the most commonly used heater
sizes. Also shown are the number of eld power circuits
required for the various models with heaters.
The unit rating plate lists a “Maximum Time Delay
Relay Fuse” or “HACR Type” circuit breaker that is to
be used with the equipment. The correct size must be
used for proper circuit protection, and also to assure that
there will be no nuisance tripping due to the momentary
high starting current of the compressor motor.
See “START UP” section for information on three
phase scroll compressor start-ups.
The eld wiring conduit connections are located on the top
right-hand corner of the unit with a wire raceway to feed
the wires down to the circuit breaker(s). See Figure 10.
