You can reverse the control panel 180 degrees. Here's how:
- Remove the four screws holding the control panel in place.
- Carefully reverse the control panel 180 degrees to the downward position for wall mounting.
- Tighten the screws back in.
Be very careful during this process not to disconnect the LCD wires behind the panel.
If that didn't work: The ATLAS/MAGNUM units also have reversible attachment tabs on the sides for stacking. Loosen the screws, swing the tab into the upright position, and retighten to install in a rack mount formation.
Heads up: If you have a MAGNUM model and are ever authorized to remove the enclosure cover, only use the original short screw in the middle threaded hole on the right side. A longer screw can puncture the internal ozone gas line, causing a leak and voiding the warranty.
