Foreword This user guide is intended for users of the Airmix™ and technicians who install and maintain it. The manual and operating instructions are bundled together in a single document. Each chapter is numbered and, where necessary, divided into sections. The table of contents on page 2 contains an overview of the chapters and paragraphs, with references to page numbers.
These valves are controlled by a gear-rack drive. The Airmix™ is equipped with a power cord with a plug for the fan, and a power cord for the gear-rack drive. The Airmix™ has no internal controls.

Airmix™. 1.3 Use The Airmix™ is designed to mix hot humid air from cultivation areas with cool dry air from above the screen cloth in a greenhouse. This circulates air horizontally, and improves the climate distribution in a greenhouse.
(unwanted air flows and temperature differences). The Airmix™ is fitted with the same fan as the Enfan. The inlet side of this fan is attached to the aluminium housing. Two valves are mounted in the housing, so air can be sucked in from both above and below the screen cloth (Figure 2).
Do not connect the fan or the gear-rack drive to the power supply until assembly has been completed and the system has been suspended. Only use self-locking nuts to assemble and mount the Airmix™! Failure to do so may result in parts vibrating loose and falling off.
4.2 Suspending the Airmix™ It is easier to suspend the Airmix™ before attaching the fan to the aluminium housing, so only attach the fan when the Airmix™ is already suspended. Proceed as follows: Choose a suitable location; make sure that any shrinkage of the screen cloth can be compensated by suspending the Airmix™...
4.3 Attaching the fan After the Airmix™ housing has been suspended, the fan can be attached to it. It is more easy to connect the power supply cable at the fan, before you attach the fan to the Airmix™ housing. Follow the instructions in chapter 5.
Figure 5 Levelling the Airmix™ 4.4 Installing the extension If it is not possible to connect the opening on the top of the Airmix™ directly to the screen cloth, an extension must be installed to bridge the gap. This procedure is described below.
The lower screen cloth must still be able to move between the Airmix™ housing and the spacer, so that it can be opened and closed. To ensure that no air is sucked in between the Airmix™ and the spacer, brush strips and PVC flaps must be mounted on the spacer.
In practice, a greenhouse might be divided into multiple sections, where each section has its own climate control. That is why one Airmix™ in each section has to be equipped with a valve position sensor. The valve position sensor must be mounted before the Airmix™ is suspended.
The Airmix™ system requires modifications to the screen cloth, since a hole must be made in it so that the Airmix™ can draw in air from above. This hole must be at least as large as the opening of the Airmix™, and reinforced with triple stitching.

6. Operation/using for the first time Operating the fan of the Airmix™ is simple: if it is connected to the power supply it will start ventilating, if it is disconnected it will stop ventilating. It is possible to set the speed by adjusting the voltage at the plug with something like a control transformer, but this is not part of the Airmix™.
