Page 4: Electrical Requirements
All electrical components, whether included with the VentCool system or supplied by others, must be rated for the fan system’s electrical load requirements; please refer to the VentCool Tahoe Series specifi cations table for the electrical load requirements of the specifi c model to be installed. -
Page 5: Ventilation Requirements
VENTILATION REQUIREMENTS It is very important that the attic be suffi ciently ventilated for the fan system to operate properly. Without adequate ventilation, hot air exhausted from the home cannot easily escape from the attic, which creates back-pressure that will substantially reduce the fan’s performance. Operating this fan in an attic with less net free ventilation area than recommended will decrease its airfl ow and energy effi ciency. - Page 6 WHERE TO LOCATE THIS FAN The best location for this fan is determined by an understanding of its theory of operation: As a home heats up during the day, a large amount of heat is retained in its structure and contents.
- Page 7 INSTALLATION: GRAVITY DAMPER GRAVITY DAMPER ORIENTATION NOTE The ideal orientation of unit’s gravity damper is in a level position. If necessary, however, the damper can be in- stalled at a slight angle. TIP: before beginning the installation, make sure that the fan assembly is undamaged, and that the fan blade rotates freely.
- Page 8 Make sure that the exact location chosen for the rough opening will allow installation of the eggcrate inlet grille, and will not interfere with any lighting fi xtures, smoke alarms, or other objects installed in the ceiling. 5. Remove any insulation from the area of the exact chosen location, and make sure that no wiring, plumbing, bracing or other building elements will interfere with the damper...
- Page 9 INSTALLATION: FAN & DUCT NOTES: • The fan assembly must be soundly supported by attachment to structurally sound framing. Provide additional framing with minimum 2-by-4 lumber as needed for fan support. • Each fan assembly should be positioned with at least 24” of free space in front of the fan, for air to be freely blown into the attic by the fan.
