DESCRIPTION

These products are listed by UL under UL file No. E78414.
These products use a sirocco fan driven by a DC motor powered by an Integral transformer. The motor Is designed to have a long operating life, high dynamic response, higher speed ranges and saving energy. The grille covering the fan body is a spring-loaded, quick removal type. A damper for preventing air counter flow is provided. The blower uses a high-capacity sirocco fan developed to reduce the noise level. The lighting unit is an energy-saving LED lighting device that uses one 10 W LED lamp and produces almost the same illumination as a standard 40 W incandescent lamp. Night light feature consumes around 0.1 to 0.4 W.
This Panasonic ventilating fan model is equipped with a humidity sensor that tums the fan on automatically when humidity increases rapidly, or when humidity rises above a 30% – 80% relative humidity set-point.

OPERATION

*1 The product will continue to run for about 20 minutes after the sensor detects that the humidity is -5 % RH lower than the humidity setting before stopping.
Note:

1. The power switch should be left on at all times.
2. The product will also run when the humidity rises rapidly but does not reach the humidity trigger setting, and then stop after the time delay.
3. The activation humidity settings on the dial are continuous from 30 %RH – 80 %RH.
4. The humidity detected by the sensor may differ from the value on your hygrometer.
5. The product may cycle on and off if the humidity is constantly near the trigger point. This can be addressed by raising the humidity trigger setting on the dial.
6. The fan will run for 20 minutes when power switch is first turned on, regardless of the humidity sensor settings. After 20 minutes, the fan will retum to sensor mode.

PRACTICAL GUIDE TO INSTALLATION

Properly insulate the area around the fan to minimize building heat loss and gain. Loose fill or bait insulation can be placed directly over the fan housing in the attic. Our fans do not create excessive heat that is a common problem with recessed light fixtures or some competitor’s fan/light combination. Our efficient cool-running motors do not create enough ambient heat to be subjected to these limitations. The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated air flow.
