INSTALLATION
RECEIVING THE RANGE
Upon receipt, check for freight damage, both visible and concealed. Visible damage should be noted on the
freight bill at the time of delivery and signed by the carrier's agent. Concealed loss or damage means loss or
damage, which does not become apparent until the merchandise has been unpacked.
If concealed loss or damage is discovered upon unpacking, make a written request for inspection by the
carrier's agent within 15 days of delivery. All packing material should be kept for inspection.
Do not return damaged merchandise to Lang Manufacturing Company. File your claim with the carrier.
Prior to un-crating, move the range as near its intended location as practical. The crating will help protect the
unit from the physical damage normally associated with moving it through hallways and doorways.
