The Anden Model A320V1 and A320V3 Dehumidifiers are designed to control humidity levels in various environments. These units are capable of removing significant amounts of moisture from the air, contributing to improved air quality and preventing issues associated with high humidity.

Function Description:

The primary function of these devices is dehumidification. Air is drawn into the unit through an inlet, passes through a filter, and then over cooling coils where moisture condenses. The dehumidified air is then reheated and discharged through an outlet. The units feature an on-board control panel with an ON/OFF button to power the unit, UP/DOWN buttons to adjust the desired humidity setting, and a MODE button for accessing optional features and installer settings. The display shows the current humidity setting, measured humidity, and operational status (e.g., "AIR SAMPLING," "DEHUMIDIFYING," "REMOTE," "EXTERNAL").

The dehumidifiers can operate in two primary modes:

1. Using the Dehumidifier Control: The unit samples the air, compares the measured humidity to the setpoint, and activates the compressor if the humidity is above the setpoint. It continues to dehumidify until the humidity drops 3% RH below the setpoint. The sampling rate can be adjusted in the installer set-up.
2. Using an External Control (e.g., Model A77 or dry contact control): The dehumidifier can be wired to an external control that measures humidity and signals the unit to turn on or off. In this mode, the dehumidifier's on-board display will show "REMOTE" or "EXTERNAL," indicating that it is being controlled externally. This setup is particularly useful for precise humidity management in specific areas, such as near a plant canopy, and eliminates the need for the dehumidifier's blower to run solely for sampling.

Usage Features:

• Flexible Installation: The dehumidifiers can be floor-mounted (requiring a leveling feet kit, not included) or suspended using hanging brackets (included) and threaded rods. Proper leveling is crucial for effective drainage.
• Ducting Capability: A duct kit (part number 5807, not included) can be used to integrate the dehumidifier into a ductwork system, allowing for remote air intake and discharge.
• External Control Options: The units support control via the Anden Model A77 control or any alternative dry contact humidity control system. This allows for centralized or specialized humidity management.
• Daisy Chain Wiring: Multiple dehumidifiers can be wired in a daisy chain configuration, controlled by a single Model A77 or dry contact dehumidistat. This enables synchronized operation of several units to manage humidity across larger or multiple areas.
• Adjustable Humidity Setting: Users can set their desired relative humidity level using the UP/DOWN buttons on the control panel or external controls.
• Installer Set-up Menu: A dedicated installer menu allows for configuration of settings such as air sampling rate and RH offset, and enables/disables external control.
• Installer Test Mode: A four-minute test mode verifies proper wiring and operation of all components, including the compressor and blower.

Maintenance Features:

• Filter Access: The MERV 11 filter is easily accessible for removal and replacement, requiring a minimum of 18 inches of clearance at the inlet side. Regular filter changes are essential for maintaining airflow and efficiency.
• Drainage System: The unit includes a 3/4" FNPT drain for condensate removal. A P-trap (included) is required for proper draining, and a vacuum break is recommended if connecting to a condensate pump or shared drain line.
• Float Switch Integration: A condensate overflow safety switch (float switch) can be wired to the dehumidifier's control board to prevent overflow in case of drainage issues.
• Diagnostic Codes: The control panel displays error codes (E1-E8) to indicate specific failures such as sensor malfunctions, communication loss, insufficient capacity, or float switch open. These codes aid in troubleshooting and identifying the root cause of operational problems.
• Troubleshooting Guide: The manual provides a comprehensive troubleshooting guide with common symptoms, possible reasons, and step-by-step procedures to resolve issues, including checks for power, filter condition, ductwork blockages, and unit leveling.
• Service Parts List: A detailed list of service parts with corresponding part numbers is provided, facilitating easy identification and ordering of replacement components.
