Fan

Battery

Solar panel

PCB

CO2 sensor

Filter

Place the filter with the pink side up into the hat.

Insert the filter holder in the hat. Start with one of the short sides, and align the pins on the filter holder with the holes in the hat.

Now push the filter holder in all the way.

Remove the plastic protective film from the solar panel.

Slide the solar panel all the way into the solar panel holder.

Note the air direction on the fan. The arrow should be pointing up.

The wires need to be on the top of the fan and not go through the case on the side.

Insert the fan all the way into the fan holder

Pull the fan wires through the hole in the bottom of the case.

Push the fan holder tightly into the case.

Find the hole on the side of the case just below the "Sigrow" text.

Insert the solar panel cable through this hole.

The Sigrow logo should be towards you.

The rectangular hole should be to the left of the middle.

The hole for the fan wires should be to the top right.

Pull the solar panel wires through the PCB plate.

Push the PCB plate all the way down into the case.

Snap off the two thin strips of the PCB on each side.

Ensure that the ports of the connectors are open before inserting the wires.

Open

Closed

Attach the wires of the CO2 sensor in the same way as in the photo.

Twist the CO2 sensor one time so the wires are not lose.

The blue and green wire should be on the outside of the PCB.

Use a zip tie to secure the CO2 sensor the the top of the PCB.

Connect the fan to the watermellon connector.

Connect the solar panel to the watermellon connector.

Make a loop of the excess fan wire.

Place a small piece of plastic from a filter on the negative side of the battery holder. The negative side is marked with (-) and is on the side towards the solar panels.

Insert the battery with the correct orientation into the battery holder.

Secure the battery with a zip tie.

The zip tie is inserted from the front, just below the "Sigrow" text and goes around the battery and through the PCB again.

The zip tie is then sequred with another zip tie.

Cut off the remaining parts of the zip tie.

Slide the PCB into the case.

Remove plastic from the solar panels.

Put the hat on the case.

Make sure that the holes in the side of the hat are on the side with the solar panels.
