Installation
Door Closures
The compact air-handling unit service doors are equipped with
safety closures. When the door handle is moved down, the safety
closure keeps the doors just ajar. To fully open the door, the door
handle must be moved back to the horizontal position. Then the
door is released. To close the door, proceed in the reverse order of
steps. Each door is equipped with one lockable closer.
