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 sav e
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.
