UNPACKING THE DEHUMIDIFIER

Remove the unit from the carton. Cut the retaining band that secures the compressor to the shipping bracket and remove the band and the bracket. See FIGURE 2.

INCLUDED IN THE CARTON

• Dehumidifier
• Installation manual
• Hanging brackets
• Model A77 control
• 3/4″ MNPT x 3/4″ hose barb fitting
• 10 feet of 3/4″ clear PVC flexible drain hose
• Terminal screwdriver
• 30 feet of thermostat cable
• MERV 11 filter

LOCATION CONSIDERATIONS

This appliance is classified as to not be accessible to the general public. 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.
2. Avoid locating the dehumidifier inlet too near a supply register. Space is not usually available to totally avoid this, but minimizing the amount of cold air that is discharged to the dehumidifier inlet will improve moisture removal performance of the dehumidifier.
3. Account for handling dehumidifier condensate by considering drain or sump pump locations.
4. Leave appropriate room on the drain side of the dehumidifier for wiring and service.
5. Allow 18″ minimum clearance near the inlet and outlet of the dehumidifier. This will allow easier removal/installation of the filter, as well as ensure no loss of airflow due to restrictions. Clearance of 18″ minimum is also recommend on the service panel side of the dehumidifier, should any maintenance be needed.

FLOOR MOUNTING

The drain hose must continuously slope downward toward the drain. Use solid supports as needed to elevate the unit enough to allow for continuous drain slope. Use the adjustable feet to level the unit right to left and front to back so that unit drains properly.

SUSPENDING THE DEHUMIDIFIER

INSTALL BRACKETS FOR SUSPENDING UNIT

The brackets are designed to accommodate up to 1/2″ threaded rod.

1. Insert bracket into slots on the bottom of the base. See FIGURE 4.

2.  Rotate the bracket up toward the dehumidifier. With a 5/16″ hex socket (not provided), secure the bracket to the side of the dehumidifier using

   10 sheet metal screws (provided). See FIGURE 5.

3. Repeat for remaining three brackets.

HANGING THE DEHUMIDIFIER
Use the threaded rod to suspend the unit from appropriate ceiling structure. The unit weight is 118 lbs. Install vibration isolators if located in an area where noise could be a concern. Level unit right to left and front to back so that unit drains properly.

DUCTING
Use duct kit part number 5790 for installing ductwork to the dehumidifier. Reference the instructions provided with duct kit 5790 for installation details.

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″ 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. If hard pipe is used, PVC primer and cement is recommended for the slip fit connection. Test all joints to ensure they are leak free before completing the installation.

LEVELING

The feet can be adjusted to level the unit, and if required, to accommodate drain fittings and a secondary condensate pan Leveling is required to ensure proper drainage from the dehumidifier. See FIGURE 7.

CONDENSATE PAN, CONDENSATE PUMP AND FLOAT SWITCH

A condensate pan is recommended when suspending the dehumidifier over finished areas or product. Adhere to local codes regarding draining of the condensate pan. If a condensate pump is needed, install it in the condensate pan as well.

Install a condensate overflow safety switch (i.e. float switch) in the condensate pan, remove the factory installed jumper wire between the Float Switch terminals on the control and wire the float switch to the dehumidifier as shown in FIGURE 8. Overflow safety switches on condensate pumps can be wired to the Float Switch terminals in a similar fashion.

3. After three (3) minutes of sampling, the measured humidity will be compared to the setting:
   a. If the humidity is above the setting, the dehumidifier compressor turns on and “AIR SAMPLING” will be replaced by “DEHUMIDIFYING”. The compressor remains on until the measured humidity falls 3% RH below the setting.
   b. If the measured humidity is below the setting, the blowers turn off and the display returns to showing the RH setting.

4. The dehumidifier will sample again after the number of minutes selected during the Air Sampling portion of the SYSTEM SET UP (see page 9), or any time the humidity setting is lowered.

USING THE MODEL A77 CONTROL

1. Press the ON/OFF button to turn the dehumidifier control ON. “REMOTE” will show on the display to indicate that an external control is wired to the dehumidifier.
2. At the Model A77, press the ON button; the Model A77 will display the measured RH.
3. Use the UP or DOWN button on the Model A77 to adjust the humidity setting as desired.
4. If the RH measured by the Model A77 rises above the setting, the dehumidifier will turn on. “DEHUMIDIFYING” will appear on the dehumidifier control display to show that the Model A77 is calling for dehumidification. The dehumidifier will turn off when the RH measured by the Model A77 drops 3% RH below the setting.

SYSTEM SET-UP & CHECKOUT

Skip set up and proceed to INSTALLER TEST MODE on page 9 unless:

WIRING AND SET-UP

MODEL A77 CONTROL

The Model A77 will measure the relative humidity and turn the dehumidifier on and off to control the humidity level to the desired setting. The humidity setting can be adjusted from the control, while the display allows easy access and monitoring of the humidity level in the space. It is recommended that the Model A77 be mounted at/near canopy height. Shield the Model A77 from direct exposure to HPS or LPS lighting.

NOTE: Use 18-22 AWG wire for control wiring.
Humidity can be controlled using the internal dehumidifier control, a Model A77 control, or a different external control like a thermostat.

Instaing an external control eliminates the need to run the dehumidifier blower for sampling, as the control is constantly measuring the humidity close to the canopy. When the humidity level rises above the setting, the dehumidifier is turned on.

TO INSTALL AND USE THE MODEL A77 CONTROL, COMPLETE ALL STEPS:

1. Unplug the dehumidifier or turn off power to the circuit at the breaker or fuse.
2. Run thermostat cable (use 18-22 AWG wire) from the Model A77 to the control of the dehumidifier.
3. Trim about 1/4″ of insulation from the end of the wires on each end. Insert the wire into the terminals as shown in FIGURE 10.
4. Restore dehumidifier power.

TO SET THE DEHUMIDIFIER TO USE THE MODEL A77 CONTROL, COMPLETE ALL STEPS:

1. With power to the dehumidifier, use the ON/OFF button to set the dehumidifier to the OFF position.
   NOTE: If the display backlight is not on, the first button press (any button) will only turn the backlight on. Press the button a second time to achieve the desired function.

2. Hold the MODE button on the on-board control for 3 seconds to enter the Installer Set-up Menu.

3. The display should now read REMOTE on the left and DISABLED on the right. Use the UP or DOWN arrow buttons to set this to ENABLED.

4. Once the display reads REMOTE ENABLED, press the MODE button to cycle through the other settings until the display blinks DONE for 3 seconds.

5. Use the ON/OFF button to turn the dehumidifier ON. The display on your unit should read REMOTE.

6. Locate the Model A77 that you just set up. On the Model A77, press the ON button and use the arrow buttons to set your preferred%RH setpoint. When setting up in REMOTE mode for the first time, your dehumidifier will wait 3 minutes before starting to dehumidify, regardless of ambient conditions.

ALTERNATIVE EXTERNAL CONTROL

Alternatively, use any other humidity control system as long as it has a dry contact, normally open output dedicated to controlling the dehumidifier. Reference the installation literature provided with the alternative control for wiring, set-up, and operating details.

TO INSTALL AND USE AN ALTERNATIVE EXTERNAL CONTROL, COMPLETE ALL STEPS:

• Unplug the dehumidifier or turn off power to the circuit at the breaker or fuse.
•  Run thermostat cable (use 18-22 AWG wire) from the alternative external control to the control of the dehumidifier.
•  Trim about 1/4″ of insulation from the end of the wires on each end. Insert the wire into the terminals as shown in FIGURE 11.
•  Restore dehumidifier power.

TO SET THE DEHUMIDIFIER TO USE THE ALTERNATIVE CONTROL, COMPLETE ALL STEPS:

1. With power to the dehumidifier, use the ON/OFF button to set the dehumidifier to the OFF position.
   NOTE: If the display backlight is not on, the first button press (any button) will only turn the backlight on. Press the button a second time to achieve the desired function.

2.  Hold the MODE button on the on-board control for 3 seconds to enter the Installer Set-up Menu.

3. Press MODE again and the display should change to EXTERNAL in the center, and DISABLED on the right. Use the UP or DOWN arrow buttons to set this to ENABLED.

4. Once the display reads EXTERNAL ENABLED, press the MODE button to cycle through the other settings until the display blinks DONE for 3 seconds.

5. Use the ON/OFF button to turn the dehumidifier ON. The display on your unit should read EXTERNAL. Even if there is a demand for dehumidification according to your external control, the dehumidifier will wait 3 minutes before turning on for the first time only.

DAISY CHAIN WIRING

Anden dehumidifiers can be wired in a daisy chain application, allowing one Model A77 or alternate dry contact dehumidist at to control any number of dehumidifiers wired together. Reference the dehumidifier Installation and Operation Manual for detailed set-up and operation.

MODEL A77 AS DRIVING CONTROL

When a Model A77 is used to control the first dehumidifier, Unit #1 must be set to ENABLE REMOTE in the set-up menu. All downstream units must be set up to ENABLE EXTERNAL in each set-up menu. See page 9 for set up details, and wire as shown in FIGURE 12.

SEQUENCE OF OPERATION

Each unit in the daisy chain responds to the first unit being controlled by the A77. When the humidity level rises above the humidity setting, all units will dehumidify until the humidity measured by the A77 falls below the setting.

IMPORTANT: If the A77 or first dehumidifier experiences a fault or loses power, all downstream dehumidifiers will also stop function. If any dehumidifier in the daisy chain other than Unit #1 experiences a fault, that unit will stop operation as determined by the fault but all other units will continue operating. If any dehumidifier loses power, all downstream units will stop function.

ALTERNATE EXTERNAL DRY CONTACT CONTROL AS DRIVING CONTROL

When a dry contact control is used to control the first dehumidifier, Unit #1 must be set to ENABLE EXTERNAL in the set-up menu. All downstream units must be set up to ENABLE EXTERNAL in each set-up menu. See page 9 for set up details and wire as shown in FIGURE 13.

SEQUENCE OF OPERATION

Each unit in the daisy chain responds to the first unit being controlled by the external control. When the humidity level rises above the humidity setting, all units will dehumidify until the humidity measured by the external control falls below the setting.

IMPORTANT: If the external control experiences a fault, all downstream dehumidifiers will also stop function. If any dehumidifier experiences a fault, that unit will stop operation as determined by the fault but all other units will continue operating. If any unit loses power, all downstream units will stop function.
