GENERAL

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

The I-TECmust 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 IPBDF8-color(8" height) orIPBDF12-color(12" height) is recommended.

These instructions explain the recommended method to install the air cooled self-containedunit 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.

ANSI Z535.5 Definitions:

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.

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.

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-TECis 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-heavinessor compressor damage!

FIGURE 2A — UNIT ON LIFT

HANDLING UNIT AFTER REMOVAL FROM SKID

If a wide and tall enough opening exists, the I-TECcan be moved as a complete assembled unit. If not, it is designed to break down into two sections to allow it to pass through a 36 inch wide door.

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

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

3.Remove cabinet sides by first 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 to 30 degrees & then pull forward from the two (2) tabs supporting the rear edge.

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

5.If the unit is equipped with a CRV or ERV, you must unplug the wire harness on the left-handside 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 and/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 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.

REQUIRED STEPS AFTER FINAL PLACEMENT SECURING UNIT TO STRUCTURE

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 (Figure 9). Once this panel is removed, the CRV/ERV air duct must be removed. See Figure 6.

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 5).

After the compressor shipping bolts have been removed, the CRV/ERV air duct can be slid back in place and the compressor access panel attached.

MINIMUM INSTALLATION HEIGHT

The minimum installation height to the bottom of the roof or fixed ceiling for ducted applications is 9 ft. 7 in. This provides enough clearance to install the duct work. See Figure 7A.

The IWS Series wall sleeve has a built-invertical adjustment to fit window sill heights from31-34inches. If additional height is required, two riser platform accessories are available. The IRP3 increases the unit height by 3 inches (Figure 7B) and the IRP6 by 6 inches (Figure 7C).

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.

Shipped with the I-TECunit 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 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 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 INSTALLATIONfor 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-TECproduct 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 theI-TECunit to the structure.
