INSTALLATION
RECEIVING
All units leaving the factory have been inspected to ensure the shipment of high quality products and
reasonable means are utilized to properly pack the fan coil units to protect them in transit.
Carefully inspect all shipments immediately upon delivery. When damage is visible, note this fact on the
carrier’s freight bill and request that the carrier send a representative to inspect the damage. This may be
done by telephone or in person, but should always be confirmed in writing.
The shipment should be unpacked in the presence of the agent so that the damage or loss can be
determined. The carrier’s agent will make an inspection report and a copy will be given to the consignee for
forwarding to the carrier with a formal claim.
