System design and installation should also, where applicable, fol-
low information presented in accepted industry guides such as the
ASHRAE Handbooks. The manufacturer assumes no responsibility
for equipment installed in violation of any code or regulation. The
mechanical installation of the packaged roof top units consists of
making final connections between the unit and building services;
supply and return duct connections; and drain connections (if re-
quired). The internal systems of the unit are completely factory-
installed and tested prior to shipment.
Units are generally installed on a steel roof mounting curb assem-
bly which has been shipped to the job site for installation on the
roof structure prior to the arrival of the unit. The model number
shown on the unit’s identification plate identifies the various com-
ponents of the unit such as refrigeration tonnage, heating input
and voltage.
Carefully inspect the unit for damage. Any bolts or screws which
may have loosened in transit must be re-tightened. In the event
of damage, the receiver should:
1. Make notation on delivery receipt of any visible damage
to shipment or container.
2. Notify carrier promptly and request an inspection.
3. In case of concealed damage, carrier should be notified as
soon as possible-preferably within 5 days.
4. File the claim with the following supporting documents:
a. Original Bill of Lading, certified copy, or indemnity bond.
b. Original paid freight bill or indemnity in lieu thereof.
c. Original invoice or certified copy thereof, showing trade
and other discounts or reductions.
d. Copy of the inspection report issued by carrier
representative at the time damage is reported to the
carrier. The carrier is responsible for making prompt
inspection of damage and for a thorough investigation
of each claim. The distributor or manufacturer will not
accept claims from dealers for transportation damage.
NOTE:
When inspecting the unit for transportation damage,
remove all packaging materials. Recycle or dispose of the packaging
material according to local codes.
