Intended Use
The Fresair Air Cooling Unit is used to supply the interior with cool air. The system is designed for stationary use. It can be used while driving.

NOTE
Only install the Fresair Air Cooling Unit using the installation instructions provided in the manual.

The Fresair unit uses minimal 12V power to pull air from the outside of the vehicle, through an anti-bacterial and anti-fungal pine straw filter, delivering strong directional air through the four adjustable air vents. With the cooling mode on, the pine filter is gradually wetted through a drop system, by repetitive injection and return of circulating water from the water reservoir. The pine straw filter is never oversaturated and water usage is conserved by this regular flow of water between the reservoir and the unit. The resultant air flowing into the vehicle is cooled by an evaporative process.
The unit will continue to produce cool air until it is turned off, the connected power source is depleted, or the water reservoir is exhausted.
The unit can be used both with or without water circulation. To use it without, power on the Fresair unit and power off the pump on the control panel. With no water circulating the system acts like a simple directional fan without cooling.
The system is controlled using the control panel or the included remote control.

NOTE
The Fresair Air Cooling unit can lower the temperature within the vehicle to a certain level. The temperature depends on the type of vehicle, the ambient temperature and the cooling capacity of your unit. For the cooling capacity of your unit, see “Technical data” on page 7.

NOTICE!
Never add anti-freeze, softener, perfume, fragrance or any other substance than pure water in the reservoir. Adding substances could create foam or potentially cause leaks.

Parts: Maintenance

Fan : Located in the center of the tray, the fan draws in external air and blows internal air through the 4 directional vents.
NOTE
The fan contains carbon brushes that can degrade over time. We recommend replacing every 4 years.

Evaporative Straw Filter : Located in the tray, external air is pulled through the moistened straw causing evaporation over a large surface area resulting in the cooling of the passing air which is delivered to the internal vents. It also filters out dust, insects, and acts as a humidifier in very low humidity environments.

NOTE
We recommend inspecting the filter and washing with a hose every 3-6 months to remove dirt and debris. Depending on usage we recommend replacing the filter every 12 months.

Tray Internal Filter : An internal filter located in the tray which is responsible for filtering the excess water descending from the straw filter. The water is then recycled and returned to the water reservoir

NOTE
We recommend inspecting and gently washing the filter every 6 months. Excess amounts of dirt could prevent water from cycling through, possibly cause water leakage.

Tray Pre – Filter : Also located in the tray and is responsible for a second filtering process, avoiding the entry of dirt into the pump, protecting the pump from clogging and breaking down.

NOTE
We recommend inspecting and gently washing the filter every 6 months. Dirt can gradually accumulate which overtime lowers the equipment’s performance and can cause eventual water leakage.

Water Pumps

• INJECTION: The injection pump is located on the outside of the water reservoir and sends water to the Fresair unit.
• RETURN: The return pump is located in the tray and returns excess water to the reservoir.

NOTE
We recommend removing the pumps every 6 months and cleaning them with an air blast. Additionally, we recommend changing the pumps every 12 months.

Float Sensor : The sensor buoy is attached to the water tank and monitors the water level. If the tank is full and the low water warning light remains on, check that the sensor is inserted correctly in the reservoir with the green dot facing up. If the sensor is inserted correctly and the light remains on it should be replaced.

Control Panel : The control panel controls all the product functions. The panel is equipped with an internal safety circuit against motor and pump short-circuits. Should your unit stop working, always check the fan motor and pumps first. The control panel may turn off, protecting itself against some other electrical defects. If the control panel is completely dead, check the main fuse to the battery.

NOTICE!
Periodical maintenance is essential for optimal performance and prolonging the life of your Fresair Air Cooling unit. We recommend preventative maintenance and replacing of wearable parts annually or as outlined in the manual, coinciding with your yearly vehicle maintenance.

How to Install

Please read the instructions thoroughly prior to installing the Fresair unit. We are not responsible for damages and/or improper installation due to user error.

Step 1 – Tracing the Mounting Template
Prep Tip: It is very important that the roof surface is clean to ensure a weather-tight seal between the base of the Fresair unit and your roof. Take time to determine where you wish to install your Fresair. Ensure that the unit is placed between roof support bars so you don’t compromise roof integrity. Plan how the internal harness will run to power and reservoir.

What you’ll need: Cardboard Mounting Template, Masking Tape, Permanent Marker

1. Place the Cardboard Mounting Template over the exact roof area where you plan to mount your Fresair Unit.
2. Ensure the larger notch (side A) is positioned toward the front of the vehicle and the Cardboard Mounting Template is placed between roof supports.
3. We recommend taping the Cardboard Mounting Template to the roof to eliminate movement while tracing the outline and hole cutouts for bolt placement. Simply trace the open area of the Cardboard Mounting Template.
4. We recommend using a permanent marker so the outline is clearly visible. Once the outline has been drawn, remove the template (and tape.)

IMPORTANT: For Van Conversion you do not need to cut the exact template shape. For ease you should just cut an opening of 14.5” wide (side to side of roof) and 13” tall (front to back of roof).

Step 2 – Cutting the Opening for the Fresair Unit
Prep Tip: In order to keep the vehicle free from debris, we recommend temporarily securing a plastic drop cloth around the cutout area inside the vehicle so that debris will land inside of the drop cloth and not in your vehicle.

What you ’ ll need : Angle Grinder/Jigsaw (Cordless tools are strongly recommended), File, Sealant/Anti-Rust Paint, Plastic Drop Cloth, Safety Glasses

• Make sure to wear appropriate safety gear to protect yourself from sparks, metal ricochet, etc. such as safety glasses, gloves, long sleeves, etc.
• Cut the opening of 14.5” wide (side to side of roof) by 13” tall (front to back of roof) along the outline as closely as possible.
• File any newly cut edges and ensure edges are smooth to the touch.
• Seal the newly cut edges with anti-rust paint or sealant and allow to dry for the recommended time.
• Clean away any remaining debris from the roof to prevent rust.

Step 3 – Testing the Fit
What you’ll need: Fresair Unit

• Test the fit of the Fresair Unit by first detaching the mounting bracket and lowering it in the area you’ve just cut out and make any necessary adjustments accordingly. Be careful not to crimp or damage the water hoses.

Step 4 – Adhering the Sealing Foam Tape
What you’ll need: Fresair Unit, Sealing Foam Tape

• With the unit still in place and secure, use a permanent marker to draw an outline around the outside base of the unit on the roof.
• Remove the unit from the roof and turn the unit over.
• Stick the thicker sealing foam tape around the airbox up to the honeycomb plastic line. Cut the sealing foam tape to the correct length ensuring there are no gaps where the sealing foam tape ends meet.
• Apply a single bead of silicone along the middle of both the foam on the unit and the foam on the roof
• Carefully lower the unit back onto the roof being careful to align the bolt holes first so the foam and silicone form a weathertight seal.
• At the same time, make sure to bring wiring and tubing through the opening on the predetermined side the wiring and tubing will run to meet their connections.

Step 5 – Mounting the Fresair Unit
What you ’ ll need : Fresair Unit, Mounting Bracket, Finishing Frame Screws, Screwdriver, Crescent Wrench(es), *Self-leveling lap sealant/Silicone

• Inside the vehicle, secure the unit by attaching the mounting bracket onto each bolt, followed by a nut.
  Tighten each of the 4 nuts gradually and evenly until the sealing foam tape compresses evenly over the roof lines or ridges.

NOTE
Be careful not to over tighten the bolts as this can warp or crack the base.

• Inspect how well the foam has compressed over roof ridge lines. If there are any gaps you need to run self leveling lap-sealant around the outside of the base and outer edge of the sealing foam tape and onto the roof for a better weatherproof seal. Please allow for drying time so as not to remove any of the seal.
• Attach the finishing frame inside the vehicle using the two finishing frame screws
  (This step can be skipped if you are building custom trim to match your vehicle’s interior.)

Step 6 – Electrical
What you ’ ll need : Supplied Electrical Wiring, *Screwdriver

• Please remember to take any safety precautions when working with electrical wire. We recommend disconnecting the main power supply until the wires are connected for safety purposes.
• Run the electrical wiring from the unit to the 12V DC fuse block ensuring it is completely concealed so that the wire is not exposed to elements or incidental damage.
• Connect the positive wire (red) to the positive terminal of your fuse block.
• Connect the negative wire (black) to the negative terminal of your fuse block. Ensure both wire connections are tightened properly and completely secured to the fuse block.
• Next, test the power (using the Fresair power button on the unit) to ensure your unit turns on.

Step 7 – Plumbing
What you ’ ll need : Supplied Water Lines/Tubes, Zip Ties, Water, *Plumbing tape

• Run water lines/tubes to the area(s) you’ve designated for fill and return water. Connect the “in” hose on the water fill connector to your water supply and fill the reservoir.
• When you see water emerge from the “out” hose on the water fill connector the reservoir is full.
• Finally, power on your Fresair and ensure there are no leaks.
• Additionally, test all functions to ensure your Fresair is working properly.

NOTE
Connections to water input and/or output outside of what is included in this manual is not recommended nor is support offered for recommendations, customizations, troubleshooting or likewise.

Cleaning & Care

Please observe the following tops for the cleaning and care of your Fresair Air Cooling Unit.

• Clean the external cover of the unit removing dirt and debris on and around the unit as often as you wash your vehicle.
  

• Check regularly that all the internal and external elements are fastening and tighten when necessary. Be careful not to over tighten as you could warp or crack the base.
  

• Check regularly that the connection lines are undamaged and secure.  Check the filter every 6 months and replace every 12 months.

• Gently wash the trey internal filter every 6 months.

• Gently wash the trey pre-filter every 6 months.

• Remove the pumps every 6 months and clean them with an air blast. Change the pumps every 12 months.

• Check the fan as it contains carbon brushes which we recommend inspecting every 12 months and replaced every 4 years.
