11.3.7 Adapter plate with damper below the unit
Adapter plate
The adapter plate has no openings for supply connections. You can also route the supply lines for downflow
units through the left side panel into the unit. To do this, you must knock out the required knock-out openings.
The side panel for downflow units is the same as for upflow units. The dimensions for the four sizes can be
found on pages 27-30.
If you want to run the supply lines into the unit from below, you must drill the required openings in the adapter
plate. You cannot always pass the pipes straight down.
• Refer to the drawings on the following pages.
• Provide membrane grommets for the drilled openings to seal the adapter plate.
Damper
• Connect the enclosed cable at the actuator according to the enclosed manufacturer‘s instructions.
• Place the damper so that the protruding axis on which the motor has to be mounted is at the rear left.
• Mount the actuator on the left-hand side of the damper according to the enclosed manufacturer‘s
instructions.
• Attach the prepared (with openings) adapter plate to the damper with the enclosed screw connections.
• Route the cable through the knock-out opening in the adapter plate.
• Place the adapter plate with the damper underneath on the raised floor stand.
• Place the A/C unit on the raised floor stand.
• Route the cable up the left side into the e-box.
The adapter plate can be fastened to the left and right of the unit frame with two self-tapping screws each.
The fastening prevents the plate from slipping slightly due to vibrations.
