General

The Deluxe Food Warmer (steamer) produces a steam 

using plain tap water for quick heating and reconstitut-

ing of food items.  Simple push-button action delivers 

a shot of water which is immediately converted into 

steam.  Because the amount of steam is consistent, it 

removes the guesswork and produces a uniform fin-

ished product from one operator to the next.
This manual provides the safety, installation and oper-

ating procedures for the Deluxe Food Warmer (steam-

er). We recommend that all information contained in 

this manual be read prior to installing and operating the 

unit. 
Your Deluxe Food Warmer (steamer) is manufactured 

from the finest materials available and is assembled to 

Roundup’s strict quality standards.  This unit has been 

tested at the factory to ensure dependable trouble-free 

operation.
