Page 7: Installation And Accessories
Installation and Accessories Before installing the coffee roaster, unpack the appliance and read the installation and operation manual. Locations For your Roaster - Basic Requirements We believe the roaster will prove most valuable to your business if its located where your customers can see it in operation. You may or may not be able to do that, but there are a few essential requirements for the installation of the roaster. - Page 8 Venting options include placing the roaster under an existing exhaust hood such as in a commercial kitchen, venting directly into a steel vent pipe, or the Sonofresco vent hood. We recommend the dedicated vent hood shown in Figure 1. The vent hood will allow the roaster to be vented greater distances and will eliminate the possibility of back pressure and wind affecting the roaster associated with direct venting.
- Page 9 The Sonofresco Vent Hood also incorporates a halogen light aimed at the roast cham- ber, to highlight the roasting process. The basic hood installation is shown below.
