PRE-INSTALLATION
Unpack and Inspect Units —
All units are carefully
inspected at the factory throughout the manufacturing process
under a strict detailed quality assurance program, and, where
possible, ALL major components and sub-assemblies are care-
fully tested for proper operation and verified for full compli-
ance with factory standards. Operational testing of some cus-
tomer-furnished components such as electronic control valves
and digital controllers may be a possible exception.
Each unit is carefully packaged for shipment to avoid dam-
age during normal transit and handling. Equipment should al-
ways be stored in a dry place, and in the proper orientation as
marked on the carton. All shipments are made F.O.B. factory
and are the responsibility of the receiving party to inspect the
equipment upon arrival. Any obvious damage to the carton
and/or its contents should be recorded on the bill of lading and
a claim should be filed with the transportation company, and
Carrier should be advised. After determining the condition of
the carton exterior, carefully remove each unit from the carton
and inspect for hidden damage. At this time, check to make
sure that “furnished only” items such as thermostats, grilles etc.
are accounted for whether packaged separately or shipped at a
later date. Any hidden damage should be recorded and imme-
diately reported to the transportation company, a claim should
be filed with the transportation company, and Carrier should be
notified. In the event a claim for shipping damage is filed, the
unit, shipping carton, and all packing must be retained for
physical inspection by the transportation company. All equip-
ment should be stored in the factory shipping carton with inter-
nal packing in place until installation.
At the time of receipt, the equipment type and arrangement
should be verified against the order documents. Should any
discrepancy be found, the local sales representative should be
notified immediately so that proper action may be taken.
Should any questions arise concerning warranty repairs, the
factory must be notified BEFORE any corrective action is tak-
en. Where local repairs or alterations can be accomplished, the
factory must be fully informed of the extent and expected cost
of those repairs before work is begun. Where factory opera-
tions are required, the factory must be contacted for authoriza-
tion to return equipment and a Return Authorization Number
will be issued. Unauthorized return shipments of equipment
and shipments not marked with an authorization number will
be refused. In addition, any claims for unauthorized expenses
will not be accepted by the manufacturer.
Protect Units from Damage —
All equipment is de-
signed and fabricated with robust materials and presents a
rugged appearance. Still, great care must be taken to assure
that no force or pressure is applied to the coil, piping, or drain
stub-outs during handling. Depending on the options and ac-
cessories, some units may contain delicate components that
may be damaged by improper handling. All units shall be han-
dled by the chassis or as close as possible to the unit mounting
point locations. In the case of a full cabinet unit, the unit must
be handled by the exterior casing. This is acceptable provided
the unit is maintained in an upright position, and no force is ap-
plied that may damage internal components or painted
surfaces.
The equipment must always be properly supported. Tempo-
rary supports used during installation or service must be ade-
quate to hold the equipment securely. Equipment should al-
ways be stored in the proper orientation as marked on the car-
ton. To maintain warranty, protect units against hostile
environment (such as rain, snow, or extreme temperatures),
theft, vandalism, and debris on jobsite. Equipment covered in
this manual is not suitable for outdoor installations. Do not al-
low foreign material to fall into drain pan. Prevent dust and de-
bris from being deposited on motor, fan wheels and cooling/
heating coils. Failure to do so may have serious adverse effects
on unit operation, and in the case of the motor and blower as-
sembly, may result in immediate or premature failure. Manu-
facturer's warranty is void if foreign material is allowed to be
deposited on the motor or blower wheels of any unit. Some
units and/or job conditions may require some form of tempo-
rary covering during construction.
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. 1-28). 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. Adjust blower motor as
required.
3. Perform "Dry Fit" of valve assembly that may be shipped
unattached to unit coil assembly. Should any questions
arise on fit up please contact your local representative.
4. Horizontal plenum type 42CE units may be shipped with
a bottom return-air inlet. These units may be converted to
rear return as outlined in Appendix C.
5. Hi-Performance plenum-type 42DC units may be
shipped with a bottom return-air inlet. These units may
be converted to rear return as outlined in Appendix C.
