Installation
Initial Considerations
Unpack the Urn
Remove the cardboard carton from around the urn. Be careful not to scratch the stainless
steel with any tools. Unwrap any plastic wrapped items. Open both liner covers and
remove materials inside the liners. Remove the control enclosure to expose electric
connections.
Select a sight for the urn
The Urn must be placed on a sturdy, leveled table. The table must have a tray to collect
liquid from the faucets. To set up initially and adjust later, the installer must have access to
the side of the urn where the controls are located. Be sure to allow for space in the sight
selection.
Water and Electric
The electric ratings are printed on the nameplate of the urn and on the rough-in drawing.
The urn must be connected to a branch circuit with its own shut-off.
A water line must be run to the connection location. The urn has a 3/8” NPT water inlet as
shown on the rough-in drawing. Use 3/8” OD copper tubing for the connection. For
especially long runs where pressure drop is likely to be a problem, use larger tubing. The
water line should have a shut-off valve near the urn. The water pressure at the urn should
be between 30 and 70 psig.
Softened water does not make good coffee. For best results, use cold tap water. Cold
water will require a recovery time between brews. You may connect hot water if it is
necessary to brew in both liners continuously. Chlorine and lime in water are the biggest
problems in the operation of coffee brewers. Be sure the water is free of chlorine which will
deteriorate the stainless steel. Filters may be purchased to help control lime. American
Metal Ware’s warranty does not cover water problems.
Place Urn
Position the urn on the table in its operating position. Level the urn front to back and left to
right. The height of the feet is adjustable for this purpose.
Complete the Hook Up
Water Hook-Up
