• Use Lock Out/Tag Out procedures.
• Wear suitable personal protective clothing and use protective equipment for performing mechanical and
electrical installations.

The TFA STS is front-access-only for installation as well as maintenance, service, and operation. In constrained
spaces, the Installer may not be able to reach the rear mounting holes of the side floor brackets. Consequently,
the TFA STS comes with (3) rear-mounted floor brackets that should be installed
before moving the TFA STS
into place. The following placement procedure assumes that rear access is not available.
Placement procedure:
1. Determine the position of the TFA STS precisely, including clearances.
2. Install the (3) rear floor brackets based on your measurements and dimensions in the illustration below.
