LOCATION CONSIDERATIONS • Allow sufficient clearance for filter removal and to prevent airflow obstruction FIGURE 4 – FILTER ACCESS CLEARANCE • Electrical service access will require the removal of the side panel shown. Allow sufficient space for service on this side of the unit. FILTER • When suspending the unit, a condensate pan with float switch is recommended to prevent any leaks that may occur due to unforeseen drain line obstructions.

DRAIN INSTALLATION The drain outlet on the dehumidifier can be hard piped using a 3/4" PVC Slip x 3/4" MNPT fitting and 3/4" nominal drain tubing or the provided 3/4" MNPT x 3/4" hose barb fitting and 3/4" clear PVC tubing can be used to drain the dehumidifier. Always maintain a constant downward slope from the dehumidifier to the drain and do not allow soft tubing to curl up which may result in air lock. NOTE: PTFE thread seal tape is recommended for the threaded connection and hand tighten only.

MODEL A77 – REMOTE OR EXTERNAL CONTROL AND WIRING NOTE: Use 18-22 AWG wire for control wiring. The internal dehumidifier control can be used to control humidity, or a remote Model A77 Control or other external control (see below) can be wired to the dehumidifier. + - A B ODT Remote Sensor Installing an A77 or other control eliminates the need to run the dehumidifier blower for sampling as the control is constantly measuring the humidity close to the canopy.

AIR SAMPLING INSTALLER TEST MODE Use the UP or DOWN button to adjust how frequently the dehumidifier samples the air to determine whether or not to dehumidify. Fewer minutes means the dehumidifier will sample more frequently to minimize humidity swings, but increases cost to operate due to more frequent fan operation. Press MODE when done to move to the next screen.
