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.

All connections can be made through 1 3/4” hole in the bottom of the oven.

Connections should be made to the wires coming form the circuit breaker.
