Refer to the supplied control system manual for a complete description and operating
instructions.
5.8 Plant Placement
Depending on the chamber configuration, a wide variety of plant growth options are available,
from seed to full maturity, and for short to medium and tall plant species.
Plant pots or trays are placed directly on the wire shelves, or directly on the Unifloor in a TA
configuration.
The shelves can be installed in any position within the chamber, depending on the experiment
requirements. Refer to Section 3.6 Install the Light Canopies and Shelving Configuration Kits,
starting on page 15 for installation instructions.
5.9 Bypass Dehumidification – BDH Option
The Bypass Dehumidification (BDH) is an optional dehumidification system used to achieve
relative humidity setpoints below the resultant of ambient conditions and moisture load in the
cabinet. A precisely controlled volume of chamber air bypasses the heat exchanger by means of
a proportionally controlled air damper. Using the cooling system, moisture is removed from the
remaining air by cooling and reheating.
