means complying with local wiring codes.
• To limit a voltage drop, and insure efcient operation, use No.12 AWG (14 mm2) wire or larger as required by
local electrical codes.
• Always connect to a branch circuit with circuit breaker or fuse protection with an electrical rating greater than the
model hand dryer’s rated amperage shown in Table 1 - Electrical Specications.
• To avoid a hazard due to inadvertent resetting of the thermal cutout, the hand dryer must not be supplied through an
external switching device, such as a timer, or connected to a circuit that is regularly switched on and off by the utility.
• Each automatic model hand dryer must have a dedicated circuit.
• Route all eld wiring away from moving parts within the hand dryer.
CAUTION Improper mounting could result in personal injury or property damage.
• Follow the mounting height recommendations in Table 2.

Installation
1. Disconnect the power source.
2. Using Table 2 to determine the recommended mounting height, select a mounting location for the hand dryer where
no reective surfaces or objects (such as a hand basin) are directly under the infra-red sensor eye. The infra-red
sensor eye is visible from the bottom of the dryer. The minimum mounting distance from bottom of the dryer to a
reective surface is 18 in (46 cm). When two or more dryers are installed, they should be spaced apart 24 in (61
cm)
3. Use the security hex key supplied to turn the cover mounting screws clockwise to remove the cover from the dryer.
4. Using the mounting template provided, mark locations for the 4 mounting bolt holes on the wall.
5. Fasten the base to the wall, using the type of bolts recommended in Table 3
6. Each dryer must have its own dedicated circuit.
7. Connect the dryer to the nearest suitable distribution panel.
8. Replace cover, turn screws counter-clockwise making certain not to over-tighten.
IMPORTANT: Consult local and general regulations before performing dryer installation. Ensure the electrical
network is not overloaded. Always connect to a dedicated branch circuit with circuit breaker or fuse protection and an
electrical rating greater than the model hand dryer’s rated amperage shown in Table 1 - Electrical Specications.
