Thank you for purchasing a Cascade® ducted Whole House Fan. This fan has been designed to provide many years of natural, quiet, and energy-efficient cooling. Please take a few minutes to read over this manual and its accompanying documents to make sure you are prepared to install the Whole House Fan system. In particular: • The homeowner/resident should read the WHERE TO LOCATE section so that the fan will be correctly located to maximize its effectiveness and efficiency.

GRAVITY DAMPER INFORMATION The Cascade Series fan systems include gravity-closed gravity damper doors that are opened by air pressure created by fan operation. The dampers serve to block entry of air from the attic into the living space, and are provided with foam sealing and insulating material in the doors to reduce heat transfer from the attic space. The Cascade Series Whole House Fan Systems have different gravity damper sizes, depending on the specific model to be installed.
PAGE 5
VENTILATION REQUIREMENTS It is very important that the attic be sufficiently 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 airflow and energy efficiency.
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. These materials give up their heat slowly and, in doing so, continue to heat the home’s interior even though the outdoor temperature may, in fact, be very comfortable in the evening and at night.

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 installed at a slight angle. TIP: before beginning the installation, make sure that the fan assembly is undamaged, and that the fan blade rotates freely. Brace or clamp the fan assembly to a secure object, and temporarily plug in the fan’s power cord into a grounded power outlet to verify smooth and correct operation.

4. 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 fixtures, 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 assembly installation. 6.

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. • The 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. • Position the fan with a slight upward angle and in a direction minimizing disturbance to attic insulation.

INSTALLATION: WIRING & CONTROLS The Cascade PSC Series Whole-House Fan Systems require a 115 volt electrical power supply of minimum 15A ampacity and maximum 15 Amp circuit overcurrent protection. All electrical components, whether included with the Cascade system or supplied by others, must be rated for the fan system’s electrical load requirements; please refer to the Cascade Series specifications table for the electrical load requirements of the specific model to be installed.

FIGURE 4 : STANDARD 2-SPEED SWITCH OPERATION Before starting this fan for the first time, verify that: • All wiring and connections have been made according to this manual and all applicable wiring codes and standards. • No tools or construction debris have been left in, on, or around the fan. 1. Switch the hi/off/low fan speed switch to off . Turn on power at breaker panel to whole house fan. 2. Switch the fan speed switch to the desired fan speed. 3.

MAINTENANCE & TROUBLESHOOTING Make sure the appropriate circuit breakers at the home’s electrical panel are turned OFF before servicing this fan. There is no routine maintenance required for this fan other than making sure the fan assembly and gravity damper are kept clean of any possible buildup of debris. Blocking this fan’s exhaust can cause it to fail prematurely. Keep the area in front of the fan as unobstructed as possible: no object should be closer than 24” to the face of the fan.
