Inc. Food Warmer User Manual
The Alto-Shaam appliance 
must be installed in a 
location that will permit 
the unit to function for its 
intended purpose and  
to allow for proper 
cleaning, and maintenance.
1.   The appliance must be installed on a stable and 
level surface. A non-combustible, heat resistant 
surface is highly recommended.
2.   DO NOT install this appliance in any area where 
it may be affected by any adverse conditions 
such as steam, grease, dripping water, high 
temperatures, etc.
3.  The outer walls of the hot well can reach 200°F 
(93°C) to 260°F (127°C). Verify countertop material 
temperature rating with manufacturer before 
installing to ensure counter can withstand heat.
LEVELING
The heated well 
should be leveled before the 
electrical supply is connected. Level the appliance 
from side-to-side and front-to-back with the use of 
a spirit level. For appliances installed on a mobile 
stand, it is important that the floor surface be level 
due to the probability of frequent repositioning.
NOTE
It is important to apply a food grade silicone 
underneath the decor flange to seal flange to the 
countertop.
