SET UP DEHUMIDIFIER FOR INSTALLATION
LOCATION CONSIDERATIONS
The dehumidifiers should be spaced evenly
throughout the area to be dehumidified with
the following recommendations:
1. Avoid placement where the discharge of
one dehumidifier is pointing toward the
inlet of another See FIGURE 1.
2. Account for handling dehumidifier
condensate by considering drain or sump
pump locations. See FIGURE 2.
3. Leave appropriate room on the electrical
service side to remove panel for field
connections. See FIGURE 3.
The recommended orientation is to install
the dehumidifiers around the perimeter
of the room with the dehumidifier inlet
pointing toward the wall and the outlet
pointed to distribute the dry air over the
canopy. This installation maximizes allowable
plant space and works with the existing
room fans to distribute air over the canopy.

INSTALLATION
IMPORTANT: Remove plywood shipping base before proceeding to the next installation steps.
The preferred method of installation is hanging – see HANGING section on page 5.
The alternate method is floor level placement. Replace the eye bolts with the included 1/4"–20, 1.0" thread length rubber cushioned leg levelers.
In each installation the unit must be level for proper draining.
DUCTING & FILTER INSTALLATION
The preferred methods of installation are hanging, followed by floor level placement with straight through airflow. There are alternate discharge
openings on the top, bottom, and side of the unit. See FIGURE 5. If ducting the inlet, all duct connections should be installed in accordance with local
and national standards. For the highest fan efficiency, any duct bends and transitions should be made to minimize airflow losses. For the A200V1, at
least one discharge opening must remain uncovered and for the A300V1 or A300V3, at least two discharge openings must remain uncovered, one
of which must be the large opening on the panel opposite the inlet panel. More discharge openings uncovered will provide the highest capacity and
efficiency. Covers are included with the dehumidifier to close off discharge openings that are not to be used.
Before installing the unit, remove the shipping platform from the unit and install the inlet duct with filter using the 6 provided screws. Install the filter
access door using the knob to secure. See FIGURE 6.

FIGURE 11 – FLEXIBLE DRAIN TUBINGFIGURE 10 – PVC DRAIN TUBING
DRAIN INSTALLATION
The blower draws air through the dehumidifier putting the cabinet under negative pressure. As a result a P-trap is required for proper draining.
The drain outlet on the dehumidifier can be hard piped using a 3/4" PVC Slip x 1" MNPT right angle fitting and 3/4" nominal drain tubing. If flexible,
clear PVC tubing is preferred, the provided drain fitting with a right angle bend to a 3/4" hose barb fitting can be installed. NOTE: PTFE thread seal
tape is recommended for threaded connections and hand tighten only. If hard pipe is used, PVC primer and cement is recommended for the slip
fit connections. After installing the drain, pour enough water (about 2 pints) into the dehumidifier to prime the traps. Remove the air filter from the
dehumidifier to access the drain pan.
