MATERIALS:
Cover — One-piece, minimum 1/8'' (3mm) thick, white iron-casting is finished in high-gloss, acid-resistant, multicoat vitreous
enamel. Equipped with a two-position, self-returning, chrome-plated air-outlet nozzle. Air-inlet and -outlet openings are
equipped with vandal-resistant grilles. Cover is secured to mounting base with two concealed, vandal-resistant, recessed hexscrews.
Mounting Base — 14-gauge (2.0mm) plated steel with four 19/64'' (8mm) diameter mounting holes.
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 cfm.
Heating Element — Coiled nickel-chrome heating element is mounted in mica frame and protected by an automatic thermaloverload 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 airoutlet 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.

OPERATION:
No-touch operation: electronic sensor automatically turns dr yer on when hands or self-returning nozzle are held under
air-outlet opening and across path of sensor. Two-position nozzle is adjustable to direct airflow: up position directs airflow down
for hand drying and down position directs airflow up for face drying. After dr ying face, release nozzle and it automatically
returns to up position. Remove hands or release self-returning nozzle from path of sensor and dryer stops. Dryer will not stop
by itself before user is satisfied hands or face are dry. Dryer operates only when actually drying hands or face, which saves
energy and operating costs. Electronic sensor will automatically shut dryer off 1-1/2 minutes after dr yer turns on if inanimate
object, such as tape or chewing gum, is placed across air-outlet opening. After inanimate object is removed, electronic sensor
automatically resets itself and dryer operates normally.
