Setup
1. Pre-Installation Check
Before beginning installation, perform a power-on test to ensure the fan is functioning correctly. Familiarize yourself with the fan's components and controls.
2. Selecting Installation Location
Choose a wall location between the two rooms where you wish to balance temperature. Ensure there are no electrical wires, plumbing, or structural elements within the wall at the chosen location. The fan is designed for in-wall mounting and can accommodate wall thicknesses from 3.5 inches up to 6.2 inches.
3. Marking and Cutting the Opening
Use the provided installation template to mark the precise cutting area on both sides of the wall. Carefully cut the circular opening for the fan's main body and drill pilot holes for the mounting screws. Measure twice, cut once to ensure accuracy.

4. Mounting the Fan
Insert the fan body into the prepared opening. The adjustable sleeve allows for a snug fit within various wall thicknesses. Secure the fan to the wall using the provided mounting hardware, ensuring it is level and stable. The fan can be hardwired or plugged into a standard 110V outlet using its 6-foot power cord.

Operating Instructions
The fan can be controlled via the integrated control panel or the included remote control. The intelligent controller features 10 precise fan speeds with temperature, timer, and cycle programming.

1. Power On/Off
Press the power button on the control panel or remote to turn the fan on or off. The fan has a memory retention feature, resuming its last settings upon power restoration.
2. Mode Selection
Press the 'Mode' button to cycle through available operating modes: Continuous Operation, Cold Trigger Mode, and Hot Trigger Mode.
- Continuous Operation: The fan runs continuously at the selected speed, regardless of temperature.
- Cold Trigger Mode: The fan activates to blow cold air into the room when the ambient temperature exceeds the set temperature. Ideal for cooling.
- Hot Trigger Mode: The fan activates to blow hot air into the room when the ambient temperature falls below the set temperature. Ideal for heating.
Video: This video provides a detailed overview of the fan's operational modes, including continuous, cold trigger, and hot trigger, and demonstrates how to switch between them using the control panel and remote.
3. Temperature Setting
In Cold or Hot Trigger Mode, use the 'Up/Down' buttons to set your desired temperature. The fan will automatically adjust its operation based on this setting.
4. Fan Speed Adjustment
Use the 'Up/Down' buttons to select one of the 10 available fan speeds. Higher speeds provide greater airflow (up to 300 CFM) but may produce more noise. Lower speeds are ultra-quiet, operating below 25 decibels.

5. Reversible Airflow
The fan features a unique reversible airflow design. Press the dedicated 'Reverse' button on the control panel or remote to change the direction of airflow, allowing you to either pull air into a room or exhaust it out.

Image: This diagram illustrates the fan's two-way airflow capability, showing both intake (pulling air in) and exhaust (pushing air out) functions.
6. Timer and Cycle Programming
Utilize the intelligent controller to set a timer for automatic on/off operation or to program a cycle mode for specific ventilation patterns.
Video: This video showcases the SUPLIFE through-wall fan's quiet operation and its ability to move a significant amount of air, demonstrating its effectiveness in various room settings.
Maintenance
1. Cleaning the Fan Blades and Grille
Regularly clean the fan blades and grilles to prevent dust buildup, which can reduce efficiency and airflow. Use a soft, dry cloth or a vacuum cleaner with a brush attachment. Do not use abrasive cleaners or solvents.
2. Motor Care
The fan uses a next-gen EC motor with PWM control and dual ball bearings, designed for a longer lifespan and quieter operation. No special lubrication or maintenance is required for the motor.

Troubleshooting
- Fan not turning on: Check power connection, ensure the outlet is functional, and verify the power button is pressed.
- Low airflow: Clean fan blades and grilles. Ensure the fan is set to an appropriate speed.
- Unusual noise: Check for any obstructions around the fan blades. Ensure the fan is securely mounted.
- Temperature not balancing: Verify the correct mode (Cold Trigger/Hot Trigger) and desired temperature are set. Ensure there are no significant drafts or open windows affecting temperature readings.
