Cabinet Cooling Guide
To effectively cool a cabinet using the Airframe Series Closet

Cooling System, follow these guidelines:

• Ensure there is an intake and exhaust system in place, which can be fans or ventilation holes. This helps balance the static pressures inside and outside the cabinet.
• Position fans near the top of the cabinet to exhaust warmer air, and position fans near the lower part of the cabinet to push in colder air.
• Calculate the required CFM (cubic feet per minute) rating for the fans by dividing the dimensions of the cabinet by 1728 to get the cubic feet area, then multiply by three to account for real-world variables.

CABINET COOLING GUIDE

INTAKE AND EXHAUST
All cabinet fan systems should contain an intake and an exhaust variable which can either be fans or ventilation holes. This is required to balance the static pressures between the inside and outside room.

FAN POSITIONING
Due to natural convection, warmer air, which is less dense than colder air, will rise on its own. It is ideal to position fans near the top of the room configured to exhaust out the warmer air and position fans near the lower part of the room to push in colder air.

CFM REQUIREMENTS
A fan or set of fan’s CFM rating measures the rate at which air flows in of a space. To obtain the required CFM rating, divide the dimensions of a cabinet by 1728 to get the cubic feet area then multiply by three to account for various real world variables.

PRODUCT CONTENTS

INSTALLATION

STEP 1
Determine where you wish to mount the cooling fan unit onto your door or wall. Position the stencil and apply tape to the outer edges.

STEP 2
Use a pencil to outline the center square and four outer screw holes on the one stencil. Check for accuracy before proceeding to the next step.

STEP 3
Remove the plastic stencil and tape. If you prefer machine screws instead of wood screws to mount the fan and controller, use a power drill to create four screw holes. Recommended drill bit size around 16/64”.

STEP 4
Using a saw, cut out the center piece as outlined by your markings from step one. You may need to first drill a hole at each of the corners to fit your saw through. A power jigsaw may be preferred for thicker wood.

STEP 5
Place the fan unit into the newly cut square so that each screw hole is properly aligned. Make sure that the cut center hole is large enough that the plastic backside of the fan does not come into contact with the cabinet. This is to minimize vibrations which will can cause noise.

STEP 6
Using the four machine screws, secure the fan unit’s frame onto the cabinet or wall. Push each screw through their corresponding hole located on the frame and wall. The included wood screws can also be used instead. Tighten the nuts on the other side.

STEP 7
After mounting the fan unit onto a door or wall, locate the filter piece. If it has not yet been installed, align and insert the filter piece into the docking holes located on the backside of the fan unit.

STEP 8
Push the filter piece against the back of the fan unit to click it into position. Note that using the detachable filter will reduce air performance of the cooling fan unit.

POWERING AND SETUP

STEP 1
To power the fan unit, locate the corded wall adapter. Plug the adapter’s connector into the port marked “POWER” located on the backside of the fan unit.

STEP 2
Plug the adapter head into a standard outlet or power strip and check to see if the fan’s unit screen is on. You may need to press the leaf button if the unit was previously set to ECO Mode.

STEP 3
To set up temperature readings, locate the corded thermal probe. Plug the probe’s connector into the port marked “PROBE” located on the backside of the fan unit.

STEP 4
After plugging in the probe, check the fan unit’s screen to see that there is now a temperature reading. Position the thermal probe near your devices with the highest temperatures.

FILTER MAINTENANCE

STEP 1
To detach the filter piece, pull on its lever to release it from the backside of the fan unit. The filter should be cleaned periodically to avoid decreasing the fan’s airflow performance.

STEP 2
Rinse the filter piece with running water or wipe it down with a damp cloth to remove dust and other particles.

STEP 3
Wipe down the filter piece thoroughly with a cloth and leave it out to dry. The filter piece should be completely dry before reattaching it to the fan unit.

STEP 4
Lastly, push the filter piece against the back of the fan unit to put it back into position.

ADDING MORE FANS

You may connect an additional fan to this fan to create an intake/exhaust system. Your fan will power this additional fan and eliminate the need to connect it to its own power source.

CREATING A CHAIN
Connect the EXT cable’s Molex connector to the EXT port of your primary fan, and its DC connector to the DC port of your secondary fan.
The secondary fan will be powered by the primary fan, which will provide programming for the connected system.

PROGRAMMING

1. MODE BUTTON: Cycles through the modes: AUTO, SMART, SPEED, ALARM, BUFFER. Holding for three seconds will lock or unlock the display.

2. UP/DOWN BUTTONS: Changes the setting temperature, alarm temperature, display brightness, or
   the speed of the fan.

3. LEAF BUTTON: Turns the display off while programs run in the background. Holding will change degrees to Fahrenheit or Celsius.

4. SETTING TEMP. Shows the temperature you set the fans to trigger in AUTO and SMART Mode.

5. FAN SPEED
   Shows what speed the fans are currently running at. Six speeds are available.

6. ALARM TEMP.
   Shows the temperature that you set the fan’s alarm system to trigger. See page 22 for more information.

7. BUFFER
   Shows the buffer settings of AUTO and SMART Mode programming. See page 21 for more information.

8. PROBE   TEMP. Actively shows the current temperature that the probe is measuring.

9. ALERT ICONS Flashes to indicate if check fan alert, alarm, or display lock is being triggered.

QUICK START
Press the MODE button until you are on AUTO mode. This mode works like a thermostat. Press the up and down triangle buttons to change the SETTING temperature on the screen. The PROBE temperature is what the thermal probe is measuring. When the PROBE temperature exceeds the SETTING temperature, the fans will start running.

SPEED SETTING
In this mode, the fans will run non-stop regardless of temperature. Pressing the up and down buttons while in this mode will change the speed of the fan. Whichever speed is designated in this mode will also be the speed used in AUTO Mode and the max speed of the fans in SMART Mode.

AUTO MODE
This is the thermostat setting where the fans will start running when the PROBE temperature reaches or surpasses the SETTING temperature. The SETTING temperature can be designated by pressing the up and down buttons while in this mode. Once the fans start running, the PROBE temperature will need
to fall at least 4° F below the SETTING temp for the fans to stop running. This variation buffer can be changed. See page 21 for more information.

BUFFER SETTING
In AUTO mode, a buffer is built in to prevent your fan from turning on and off too quickly due to small variations in the environment. In SMART mode, there is a range of temperatures between each speed. You can increase or decrease this buffer or range by pressing the up and down buttons.

SMART MODE
This is the energy saving mode where the fans will change speed depending on the temperature. The SETTING temperature can be designated by pressing the up and down triangle buttons while in this mode.
For every 4° F increment that the PROBE temperature is below the SETTING temperature, the speed of the fans will decrease by one level. This increment can be changed to 2° F, 6° F, or 8° F by adjusting the Buffer Setting instructed above.
The fan speed you designated in ON Mode will also be the max speed the fan can reach. This occurs when the PROBE temperature reaches or exceeds the SETTING temperature.

ALARM SETTING
In this mode, you can set what temperature the system’s alarm will trigger by pressing the up and down triangle buttons.
When the PROBE temperature reaches or exceeds the ALARM temperature, the alarm will activate. The alarm will only activate while the controller is in ON, AUTO, or SMART Mode so remember to exit ALARM Mode once the alarm has been set.
When the alarm is triggered, the fans will run at max speed regardless of the setting and will make an audible beep every three seconds. This will keep occurring until the temperature drops below the ALARM temp. or if any buttons are pressed. The alarm can be disabled
by pressing the up triangle button until the temperature is at 140° F, then pressing the up button once more to show “OF”.

FAHRENHEIT OR CELSIUS
The temperatures displayed can be set to Fahrenheit or Celsius scale by holding the LEAF button until °F or °C is shown after the digits. All digits displayed will be automatically converted to the designated scale.

DISPLAY BRIGHTNESS
To adjust the brightness of the display, hold down the MODE button while pressing the up button repeatedly to increase the brightness. Hold down the MODE button while pressing the down button repeatedly to decrease the brightness. There are three brightness settings available.

CONTROLLER LOCK
Holding the MODE button for three or more seconds will lock the controller. The controller will still work as programmed; however, pressing any buttons will not have an effect and will cause the screen lock icon to flash and will make an audible beep three times per second. This option was designed to prevent your controller settings from being changed by accident. Holding the MODE button again for three or more seconds will unlock the controller.

ECO-DISPLAY
To conserve energy, you can choose to set the display into Eco Mode by pressing the button with a leaf on it to turn the display off. All programs will be operating in the background and fans will still be triggered to run according to the settings. Press any button will turn the display back on.

ALERT ICONS
On the bottom right of the display there are three alert icons. They are visible to show that the system’s functions are being monitored. They will flash when the controller wishes to alert you that a particular function is being triggered.
