Immediately Inspect for Shipping Damage
All containers should be examined for damage before and during unloading. The freight carrier
has assumed responsibility for its safe transit and delivery. If equipment is received damaged,
either apparent or concealed, a claim must be made with the delivering carrier.
A) Apparent damage or loss must be noted on the freight bill at the time of delivery. It must
then be signed by the carrier representative (Driver). If this is not done, the carrier may
refuse the claim. The carrier can supply the necessary forms.
B) Concealed damage or loss if not apparent until after equipment is uncrated, a request for
inspection must be made to the carrier within 15 days. The carrier should arrange an
inspection. Be certain to hold all contents and packaging material.
Installation and start-up should be performed by a qualified installer who thoroughly read,
understands and follows these instructions.
Local codes regarding installation vary greatly from one are to another. The
Fire Protection Association, Inc. states in its NFPA96 latest edition that local codes are “Authority
Having Jurisdiction” when it comes to requirement for installation of equipment. Therefore,
installation should comply with all local codes.
Install according to the spacing requirements listed in the installation section of this
manual. We strongly recommend having a competent professional install this equipment.
A licensed electrician should make the electrical connections and connect power to the unit. Local
codes should always be used when connecting these units to electrical power. In the absence of
local codes, use the latest version of the National Electrical Code.
