Alto-Shaam 300-HW/D443 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.

 The appliance must be installed on a stable and 

level surface.  A non-combustible, heat resistant 

surface is highly recommended.

 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.

 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.

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.

It is important to apply a food grade silicone 

underneath the decor flange to seal flange to the 

countertop.
