Low temp dishwasher Type II hood

[Meyer]

Hi, my client is telling me that we dont need Type II hoods on low temperature dishwasher. It operates at 120degF. Here is the cutsheet:

As far as I know we have to provide hoods on dishwashers unless this is a ventless or undercounter. Is there a particular code where it sates that low temp dishwashers are excempt from hood?

Check your IMC
Against this wording



Plus ask the nice client, where they are getting their info,,,

And let them know the ahj will more than likely not approve without a hood

507.3 Type II Hoods

Type II hoods shall be installed above dishwashers and appliances that produce heat or moisture and do not produce grease or smoke as a result of the cooking process, except where the heat and moisture loads from such appliances are incorporated into the HVAC system design or into the design of a separate removal system. Type II hoods shall be installed above all appliances that produce products of combustion and do not produce grease or smoke as a result of the cooking process. Spaces containing cooking appliances that do not require Type II hoods shall be provided with exhaust at a rate of 0.70 cfm per square foot (0.00033 m3/s

Check with you local health department, if they will allow that unit.
I believe the CA Food Code requires that commercial dishwashers achieve a utensil surface temperature of160°F.

cda posted the IMC requirement, but didn't point out the obvious …. "except where the heat and moisture loads from such appliances are incorporated into the HVAC system design or into the design of a separate removal system." This can be used in lieu of a Type II hood. I do not believe this option was intended only to be used by cooking appliances. Some cooking appliances will produce more heat and moisture than this dishwasher, and have the ability to utilize this option. Does your code have such language? and let's not discard Mark's suggestion to check with your health department. If they require 160 degrees, this unit won't work, but the next unit may still utilize this option.

I do not think the project is under the IMC. She is in California.
