INTRODUCTION
Your Whole House Ventilator is designed and engineered to provide years of satisfactory service
in cooling and ventilating your entire house. Hot, humid air is drawn from the living areas and
replaced by cooler outside air. This cooler air may be routed through selected areas of the house
by opening the proper windows and doors. A 3-speed control is supplied. A 12-hour timer, Model
1012A, is also available as an accessory.
The recommended method of installation for 16” O.C. joist construction with the 30” Whole House
fan, Model 3038R, (see pp. 3, 4, 5 & 6) completely eliminates all framing and cutting of ceiling
joists, thus providing the easiest installation available. The shutter for this installation is also
designed to give an attractive flush appearance without cutting the center joist.
