1. Product Overview
This TPI Corporation CE 20-DS single phase 20-inch diameter direct drive exhaust fan has a built-in shutter mechanism and is suitable for ventilating a building to the outside. The blade assembly (consisting of a steel hub and spider) holds the fan head’s three aluminum paddles, which are enclosed by front steel spiral wire guards for strength. The built-in shutter mechanism allows the fan to be installed without external framing, and the self-closing shutters protect the fan from rain and snow when not in operation. The permanent split capacitor (PSC) motor provides both starting torque and the ability to run at variable speeds. The motor of the TPI direct drive exhaust fan is totally enclosed, making it suitable for use in conditions that standard, unenclosed motors are not, such as in the presence of dust or other airborne debris. Industrial fans are used in workplace environments to exhaust fumes or direct air flow. Most industrial fans have coated metal parts and lubricated motors that are permanently sealed to help protect against environmental hazards, such as dirt and airborne debris or corrosive fumes. They can have fan blade cages that meet workplace safety standards, as well as a variety of mounting mechanisms for precise placement to direct large volumes of air flow. Electronic circuitry for industrial fans matches the power specifications found in the workplace and provides the initial torque needed to start up a large blade fan. Industrial fans are used in warehouses, gyms, and other commercial environments to ventilate spaces and to circulate air.

3. Setup and Installation
The TPI Corporation CE20-DS exhaust fan is designed for straightforward installation. It features a built-in shutter mechanism, allowing installation without external framing. The fan is intended to be mounted to an exterior wall, on the inside surface, with the shutters facing outward.
3.1. Pre-Installation Checks
- Ensure the mounting surface is sturdy enough to support the fan's weight (approximately 34 lbs).
- Verify power supply: 120 Volt, single phase.
- Confirm the cutout dimensions for installation. The frame outer dimensions are approximately 23.125 x 23.125 inches.
3.2. Mounting Instructions
- Prepare the wall opening: Create a square opening in the exterior wall matching the fan's frame dimensions (approx. 23.125 x 23.125 inches).
- Mount the frame: The fan frame mounts to the wall using a flange with eight holes (two near each corner). Secure the frame to the wall using appropriate fasteners (not included).
- Install the fan assembly: The motor, fan blades, and wire safety screen assembly attach to the frame. This assembly connects via four screws into nylon inserts in the frame. Rubber grommets are used to reduce vibration and noise.
- Electrical Connection: The fan is designed for direct wiring. A junction box is provided. Connect the 120VAC single phase power supply to the fan's pigtail wires inside the junction box. Ensure proper grounding. The manufacturer recommends using flex conduit for power connection.

4. Operating Instructions
The TPI CE20-DS exhaust fan is operated via a pull chain switch. This switch controls the fan's two speeds and the off function.
4.1. Powering On/Off and Speed Control
- Locate the pull chain: The pull chain extends from a small outlet box located under the motor.
- Cycle through settings: Each pull of the chain advances the switch through the following sequence:
- Pull 1: High Speed (1140 RPM, 2950 CFM)
- Pull 2: Off
- Pull 3: Low Speed (1070 RPM, 2380 CFM)
- Pull 4: Off
- Automatic Shutters: When the fan is off, the self-closing shutters will automatically close to protect the fan from external elements like rain and snow.
5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your TPI CE20-DS exhaust fan.
5.1. Cleaning
- Fan Blades and Guards: Periodically inspect and clean the aluminum fan blades and steel spiral wire guards to prevent dust and debris buildup, which can reduce airflow and efficiency. Use a soft cloth or brush.
- Shutters: Ensure the self-closing shutters are free of obstructions and can open and close smoothly. Clean any dirt or debris that may accumulate on the shutter slats or hinges.
5.2. Motor
- The motor is permanently lubricated and totally enclosed, requiring no routine lubrication.
- Inspect the motor for any unusual noises or excessive heat during operation.
5.3. Electrical Connections
- Periodically check all electrical connections for tightness and signs of wear or corrosion. Ensure the junction box cover is securely fastened.
Safety Note: Always disconnect power to the fan before performing any cleaning or maintenance.
