The Bobrick B-7128: A Comprehensive Overview

Color Finish: Stainless Steel

Voltage: 115v

Activation: Automatic

Mounting: Surface

Sound Level: 71 dBA

Rated Power: 1.7 kW

Compliance: ADA, 3-15/16" Depth

Cover:
22-gauge galvanized steel with exposed surface type-304 stainless steel with #4 satin-finish vertical grain (B-7128) or 22-gauge mild steel zinc plated with high-gloss white epoxy paint finish (B-7120). Covers with UL 94-5VA black plastic trim and side panels. Cover equipped with uniquely designed dual air outlets. Air-inlet has a vandal-resistant grille. Cover projects no more than 4" (100mm) from the wall and is secured to the mounting base with two vandal-resistant, recessed hex screws.

Mounting Base:
20-gauge (1.5mm) plated steel with four 0.236" (6mm) diameter mounting holes.

Motor:
Universal, 1/7 hp, 8000 rpm, on resilient mounting. Sealed ball bearing at drive-shaft end and self-lubricating sleeve bearing at the non-drive end. Equipped with an automatic thermal-overload switch.

Fans:
Two balanced, double-inlet centrifugal fans mounted on the motor shaft; directs airflow over the heating element at 71 cfm.

Heating Element:
Two coiled nickel-chrome heating elements mounted in a mica frame and protected by automatic thermal-overload switches. Heating elements heat air without hot spots and are inaccessible to vandals.

Electronic Control:
An infrared sensor automatically turns the dryer on when hands are held under the air-outlet opening and across the sensor's path. Removing hands from the path stops the dryer. The sensor includes an automatic shutoff approximately 1-1/2 minutes after activation if an inanimate object is placed across the air-outlet opening. Once the object is removed, the sensor resets, and the dryer operates normally.

Wall Preparation

Use the provided template to locate the mounting base on the wall.

For brick, stone, or concrete walls:

  • Drill four 0.315" (8mm) holes to fit wall plugs (0.315" x 1-1/4" or 8mm x 45mm) and screws (#10, 4.8mm x 2" or 50mm long).
  • Refer to the template for wall plug and screw installation details.

For plaster or drywall:

  • Ensure concealed backing complies with local building codes.
  • Secure with four #10 (4.8mm) round-head sheet-metal screws or 3/16" (5mm) toggle bolts (not included).

Provide electrical service from the nearest distribution panel to the mounting base according to local electrical codes.

Wiring Instructions

For 115-Volt Dryers:

  • Connect the ground wire to the terminal marked with a ground symbol.
  • Connect the black (hot) wire to the terminal marked L1.
  • Connect the neutral (white) wire to the terminal marked N.

For 208–240-Volt Dryers:

  • Connect the ground wire to the terminal marked with a ground symbol.
  • Connect the 208–240-volt wires to terminals L1 and L2.

Notes

  • The electronic sensor in automatic dryers detects movement within 6" (150mm) of the air-outlet opening.
  • Avoid installing the dryer in confined areas or close to doorways and high-traffic spaces to prevent accidental activation.
