PRE-INSTALLATION

Unpack and Inspect Units — Remove shipping wraps from all units. Check the shipment against shipping order. Make sure that furnished only items, such as thermostat, grilles, etc., are accounted for, whether packaged separately or shipped at a later date. If shipment is damaged or incomplete, file claim with transportation company and advise Carrier im- mediately.

Protect Units from Damage — The equipment must always be properly supported. Temporary supports used during installation or service must be adequate to hold the equipment securely. Equipment should always be stored in the proper ori- entation as marked on the carton. To maintain warranty, protect units against adverse weather, theft, vandalism, and debris on jobsite. Equipment covered in this manual is not suitable for outdoor installations. Do not allow foreign material to fall into drain pan. Prevent dust and debris from being deposited on mo- tor and fan wheels. Manufacturer's warranty is void if foreign

material is allowed to be deposited on the motor or blower wheels of any unit.

Prepare Jobsite for Unit Installation — To save time and to reduce the possibility of costly errors, set up a com- plete sample installation in a typical room at jobsite. Check all critical dimensions such as pipe, wire, and duct connection requirements. Refer to job drawings and product dimension drawings as required (see Fig. 1-36). Instruct all trades in their part of the installation.

Identify and Prepare Units — Be sure power require- ments match available power source. Refer to unit nameplate and wiring diagram.

1.Check all tags on unit to determine if shipping screws are to be removed. Remove screws as directed.

2.Rotate the fan wheel by hand to ensure that the fan is unrestricted and can rotate freely. Check for shipping damage and fan obstructions.
