Sensor sound suppression hood (Sssh) upgrade
These instructions tell you how to install the Sensor sound suppression hood 
option (part # 7051A1072) in any 6- or 12-slot Sensor Installation Rack . 
The hood reduces the sound produced by the Sensor ventilation fan by 
surrounding it with an enclosure lined with sound absorbing foam. A properly 
installed enclosure does not reduce ventilation fan efficiency.
Note:
Sensor racks with standard 10 inch clearance above the cooling fan 
have been tested with the hood in place. No significant increase in 
rack temperature was observed. However, installers should be sure 
objects on a wall or ceiling do not impede the free flow of cooling air 
from the hood exhaust openings.
A typical upgrade can be performed without using tools. Cleaning supplies to 
remove dust and oil from the installation will probably be required.
Preparing the hood installation surface
1. Shut off rack power at the main circuit breaker.
Warning!  Servicing a dimmer rack with power on may result in death 
or injury from electrical shock.
2. Clean dust buildup from the top of the rack with a vacuum or a damp rag.
3. Remove any oil or grease residue from the top of the rack with a mild 
detergent or degreaser solution and allow the surface to dry completely.
4. Position the hood on top the dimmer cabinet as shown below. Make sure 
the hood can be positioned with the front flush to the edge of the dimmer 
cabinet while completely covering (not obstructing) the ventilation fan.
Figure 1: Positioning the hood for installation
The hood cannot be repositioned 
after being installed, so check 
positioning with adhesive 
covered and rid of any 
obstructions before installing.
