Mounted or Floor Mounted
- Standard Height Model with Hand or Infrared Control is
ADACompliant
- Factory Tested and Shipped Preassembled
- Vandal Resistant and Easy to Clean
Specifications
Size and Capacity: Accommodates 3
users (36" models) or 4 users (54" models) at a time, using less water, energy,
and space than lavs equipped with conventional faucets. The sectional sprayhead module
(nonsectional is optional) is controlled by a pushbutton which actuates an air valve (hand
or foot control models), or an infrared sensor-actuated solenoid valve. Flow restrictor
keeps flow rate constant at 0.5 GPM per station for all pressures. Operating range is
20–100 PSI.
Bowl and Pedestal: All exposed
materials are type 304 stainless steel polished to a #4 finish. Bowl, pedestal and access
panels, frame, foot control housing; support tube; and sprayhead are heavy gauge stainless
steel. Exposed fittings are chrome plated.
Vandal Resistance: Bowl,
backsplash, and support tube are an integrally welded assembly with the support tube
welded to extruded flange from bowl. Sprayhead nozzles and pushbut-tons/ infrared sensors
are secured to unit from inside the spray-head module. Air valves/solenoid valves are
safely concealed inside the washfountain. Access panels are removable only with a hex key.
All supply and waste connections are concealed with-in the pedestal.
Barrier-Free
(ADA compliant)
Standard Height Models Only:
Wall-mounted models (when mounted at standard height) and standard height floor-mounted
models with hand or infrared control are designed to comply with all ADA guidelines on
reaches, clearances, and operation.
Standard
Equipment
Valves and Fittings: In addition to
the bowl and pedestal, the following valves and fittings are standard: manual mixing
valve, check stops, and strainers. Check valves are 1/2" NPT female.
Activation Controls
Air Valve Hand Control: Each
pushbutton pneumatically actuates a non-hold-open air single temperature valve with field
adjustable timing from 0–60 seconds. Factory set at 10 seconds minimum for ADA. Each
pushbutton actuates one valve which in turn activates one station (sprayhead nozzle).
Air Valve Foot Control: Each
pushbutton pneumatically actu-ates a hold-open air single temperature valve with slow
closing upon release of foot pressure.
Activation
Controls (continued)
Infrared Control: Each of the spray
nozzles is controlled by a separate solenoid valve. Hands placed within the washfoun-tain
bowl are detected by an infrared sensor module which activates a flow of tempered water
from one spray nozzle. Shut-off is automatic after hands are removed from the detec-tion
area.
The infrared sensor module uses two zone-focused infrared
transmitting beams—each creating a detection area not exceed-ing the bowl perimeter.
The detection range projects 6–9 inches forward at a 30° angle to each side, and
reaches 15° below horizontal. The infrared sensor is not affected by vary-ing color
tones or darkness. Direct sunlight or bright wash-room lights (up to 10,000 ft. candles)
will not activate the sys-tem. Infrared models also include solenoid valves and a low
voltage transformer as standard equipment:
- Solenoids—24V, 50/60 Hz, 1/8"
NPT. Few moving parts, and resistant to most chemicals and minerals in municipal water.
- Low Voltage Transformer—Class II,
110/24 VAC trans-former with integral universal mount. Location and junc-tion box (by
others) per local electrical code.
