Sensor sound suppression hood (Sssh) upgrade

These instructions tell you how to install the Sensor sound suppression hood
option (part # 7051A1071) in any 24-, 36- or 48-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.

Note:

Modifications to the Sssh hood needed to fit around installed power
and control conduit require tin snips, pliers and protective gloves.

Preparing to install the hood and acoustic pad

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.

Remove dust from the top of the rack and the wall behind it with a vacuum
or damp rag.

3.

Remove any oil or grease residue from the area with a mild detergent or
degreaser solution and allow the surface to dry completely.

4.

Without exposing the adhesive strips, position the hood and acoustic pad
as shown below.
