Installation

RECEIVING THE APPLIANCE

Upon receipt of the appliance, 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, 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.
Uncrate the appliance 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.

DATA PLATE INFORMATION

A data plate is located on the right side, lower front corner.
The voltages, wattage, serial number, wire size and clearance specifications are on the data plate.
This information should be carefully read and understood before proceeding with the installation.
