ACCESSORY CONTROL

MODEL 1012A Timer Switch may be used to control the fan, if it is desirable to run the fan after retiring at night. Time switch can be set manually to run up to 12 hours, turning fan off automatically at the pre-set time.

OPERATING HINTS AND SUGGESTIONS

1.Never operate your Whole House Ventilator with all outside doors and windows closed. Air will be drawn down the chimney bringing soot into the house. This could also impair fuel gas ventilation of furnaces, water heaters, etc. located in the house, possibly drawing fumes into the house. Be sure to open enough doors and windows to provide adequate ventilating air intake.

2.For best results, open windows in OCCUPIED rooms only. This will ensure maximum breeze where you want it most. Before retiring at night, bedroom windows may be opened 15-30 minutes earlier in order to give the fan opportunity to draw out bedroom heat and bring in cooling air from the outside. Windows should be opened 4”- 6” from the bottom for best results.

3.Experiment with the drawing power of the fan. It is possible, by regulating room doors and windows, to get the air movement through several rooms without actually opening windows in all the rooms. Air in the house acts like water in a pipe; it follows the path you provide.

4.DO NOT BECOME ALARMED IF FAN MOTOR FEELS HOT TO THE TOUCH. Its operating temperature is up to 90 degrees above room temperature — much too hot for your hand to stand comfortably.

MAINTENANCE

1.Turn off all electric power — remove fuse or disconnect circuit breaker — before performing any maintenance!

2.DO NOT ATTEMPT TO LUBRICATE FAN MOTOR WHEN INSTALLED. Re-lubricate per instructions on motor.

3.When shutters are in adjustment, the air stream should open the shutter completely. If this does not occur, see directions packed with shutter.

4.ALL FAN SHAFT BEARINGS ARE SEALED. They should never require any maintenance.

5.Check belt tension semi-annually for looseness and/or excessive belt wear. See Fig. 17.

6.DO NOT OVER-TIGHTEN BELT! After tightening belt, turn control to “LOW” while power supply to fan is still dis- connected. While someone watches the fan, turn power on. If fan starts easily on “LOW” belt is not too tight.

7.Check fan periodically for any material such as insulation having fallen into or onto any part of fan.
