B-750 230V

Wall Preparation: Provide framed rough wall opening 13-3/4'' wide x 9-1/2'' high (350 x 240mm). Minimum recessed depth required to finish face of wall is 3-3/4'' (95mm). Allow clearance for construction features that may protrude into rough wall opening from opposite wall. Coordinate with mechanical engineer to avoid pipes, vents, and conduits. If installed in plaster wall, it is recommended that opening be grounded on all four sides with metal plaster trim. If unit projects above top of wainscot, provide aluminum channel or other filler to eliminate gap between flange of mounting box and finish face of wall. If two units are installed back-to-back, a sound-barrier is recommended between units. Provide shims between framing and mounting box at all points indicated by an S, then secure with four #10 (M4.8) screws (not furnished). Provide electrical service from nearest distribution panel to recessed mounting box in conformance with local electrical codes

Cover — One-piece, minimum 1/8'' (3mm) thick, grey iron-casting is finished in high-gloss, acid-resistant, multicoat vitreous
enamel. Equipped with a two-position, self-returning, chrome-plated air-outlet nozzle. Graphic operating instructions are permanently fused with vitreous enamel cover for maximum vandal- and wear-resistance. Air-outlet opening is equipped with vandal-resistant grille. Cover is secured to base unit with two concealed, vandal-resistant, recessed hex-screws. Recessed Mounting Box — 16-gauge (1.5mm) steel with baked enamel finish. Rust-resistant. Base Unit — One-piece aluminum casting. Incorporates concealed, vandal-resistant air-inlet vanes on both sides and bottom. Motor — Universal, 1/10 hp, 6200 rpm, on resilient mounting. Sealed ball bearing at drive-shaft end and self-lubricating sleeve bearing at nondrive end. Equipped with automatic thermal-overload switch. Fan — Dynamically balanced, single-inlet centrifugal fan is mounted on motor shaft; directs airflow through heating element at 150 cfmHeating Element — Coiled nickel-chrome heating element is mounted in mica frame and protected by an automatic thermal-overload switch. Heating element, which is located on inlet side of fan, heats air without hot spots — inaccessible to vandals. Electronic Control — Infrared sensor automatically turns dryer on when hands or self-returning nozzle are held under air-outlet opening and across path of sensor. Remove hands or release self-returning nozzle from path of sensor and dryer stops. Electronic sensor has automatic shutoff approximately 1-1/2 minutes after dryer turns on if an inanimate object is placed across air-outlet opening. After inanimate object is removed, electronic sensor automatically resets itself and dryer operates normally
