2. How many stages encompass the air purification system used in the RH Hood?
  Air purification system incorporates three stages of filtration to maximize the capture of particulates in the airstream. The air purification system, used by the RH Hood, is tested to and complies with the EPA Test Method 202.

3. What filters are used in the three stages of the air purification system?
  Stage one can be a high efficiency (HE) stainless steel baffle filter or the Captrate Solo baffle filter to ensure capture of larger particulates. Stage two is a HEPA filter designed to capture 99.9995% of particles at 0.12 microns. The last stage is a charcoal filter, which is used for odor control.

  An exhaust skirt is fitted to the bottom of the hood to maximize the capture and removal of vapor associated with food service applications and equipment. Dimensional data for the exhaust skirt is provided. The exhaust skirt is shipped attached.

5. Is the integral electrical package on the RH hood able to be interlocked with the appliance under the hood?
  The appliance under the hood can be interlocked with the integral electrical package on the RH Hood. The Off-Delay Timer included in the package allows the hood to be interlocked with the cooking appliances under the hood. As-built wiring diagrams are provided for all connections needed.

6. How are the filters and electrical compartment accessed?
  Access panels on the front and side of the RH Hood allow access to the filters and electrical components. Please see submittal drawings or spec sheet for more information.

7. What are the electrical specifications for the RH hood?
  120 Volt, Single Phase and 60 Hz is needed. MCA is 3.0 Amps and the MOP is 15 Amps.

8. Should heat generated by the electric appliance be included in HVAC load calculations?
  Yes, heat generated should be included in the calculations.

9. How often do the filters need to be cleaned for the hood? If replacement filters are needed, then where can they be purchased?
  The frequency of cleaning is dependent on cooking load and type of cooking. The filter used in the first stage of the air purification system can be cleaned in a dishwasher. The recommendation is to remove the filter and clean weekly. The second and third stages are not washable, and will need to be checked and replaced on a quarterly basis.

10. Is there an indicator light for dirty filters?
