Initial Inspection TA Series InITIAl InSPeCTIon less than 6 tons, no more than three high. “Do not stack units larger than 6 tons.” Be certain to inspect all cartons or crates on each unit as received at the job site before signing the freight SAfeTY ConSIderATIonS bill.
Mounting Horizontal units TA Series slightly larger than the base to minimize vibration transmission to the building structure. It is not necessary to anchor the unit to the floor. (See Figure #1). MounTInG HorIZonTAl unITS figure #3 pan is usually placed on a plywood base isolated from the ceiling joists by additional layers of vibration absorbing mesh.
Should your well driller express connections. Refer to the Bosch individual data concern regarding the quality of the well water specification sheet for physical dimensions of the available or should any known hazards exist in your collar and flange.
TA Series eCM Interface board Properly sized fuses or HACR circuit breakers must be installed for branch circuit protection. See unit nameplate for maximum fuse or breaker size. The unit is provided with a concentric knock-out in the front left corner post for attaching common trade sizes of conduit, route power supply wiring through this opening.
