Recessed

Fan / Fluorescent

Light

BLOWER:

 

Plug-in, permanently lubricated, motor

MODEL 744SFLNT

Dynamically balanced centrifugal blower wheel for quiet,

efficient performance

 

Quiet operation

 

 

HOUSING:

Fits in 2” x 8” construction

Rugged, 26 gage, galvanized steel construction

4” round, polymeric duct connector with 2” tapered sleeve and no metallic clatter

Adjustable mounting brackets span up to 24”

CONTROLS: (purchase separately)

Model VS-96 - One rocker switch with “on” indicator light

Model VS-86SN - Two rocker switches - fits single outlet box

AUTOMATIC CONTROL:

Humidity control automatically turns fan ON when either of these conditions is detected:

-a rapid to moderate (user adjustable) increase of humidity

-humidity above user-adjustable set-point (50%-80% RH)

Two wire manual operation for odor control - Turns fan ON when power line through wall switch is cycled ON, OFF and back ON

Remains ON for a user-adjustable 5 to 60 minutes after

humidity has stabilized and is below set-point or after

manually initiated through power line cycling

 

 

 

 

 

 

 

 

 

 

Saves energy because unit runs only for the time required. A

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

unit controlled with a wall timer may keep fan ON longer than

 

 

 

 

required or turn it OFF before room is sufficiently ventilated

HUMIDITY SENSING RECESSED

FAN / FLUORESCENT LIGHT

MODEL 744SFLNT

TYPICAL SPECIFICATION

Fan / Light shall be NuTone Model 744SFLNT as manufactured by NuTone according to specifications listed:

Fan / Light shall have corrosion resistant steel housing and adjustable mounting brackets.

Motor assembly to be removable and permanently lubricated. Non-metallic damper/duct connector to be included.

Fan and Light to operate separately or in combination.

Fan / Light must use an R30-shaped, 2700K, 16W, high efficacy, GU24-based, compact fluorescent lamp.

Air delivery shall be no less than 70 CFM and sound level no greater than 1.5 Sones. All air and sound ratings shall be certified by HVI.

Fan / Light must be U.L. and cU.L. Listed for use in insulated ceilings (Type I.C.).

Fan / Light must be Title 24 compliant.

Fan / Light must be ENERGY STAR qualified.

The unit will have a control that will automatically turn fan ON when humidity increase is rapid to moderate (user adjustable), or when humidity is higher than user-adjustable set-point (50%-80% Relative Humidity), or when supply power is cycled from ON (for more than a second) to OFF (for less than a second) and back ON. It shall be user-adjustable to turn OFF 5 to 60 minutes after humidity has stabilized and is below user-adjustable set-point, or after manually initiated by supply power cycling.
