SET UP DEHUMIDIFIER FOR INSTALLATION

IMPORTANT: Cut the strap securing the compressor shipping support bracket and remove the strap, shipping bracket screws, and bracket. See FIGURE 1.

LOCATION CONSIDERATIONS

• Allow sufficient clearance for filter removal and to prevent airflow obstruction
• Electrical service access will require the removal of the side panel shown. Allow sufficient space for service on this side of the unit.
• Always install the dehumidifier in a condensate pan when locating in or over a finished space.

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. 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. If hard pipe is used, PVC primer and cement is recommended for the slip fit connection. Remove drain insert before priming and gluing in the PVC fitting. Replace drain insert after PVC glue has fully dried.
CAUTION
Do not damage drain insert. The drain insert is a critical feature of the dehumidifier drain management system.
WARNING
Running the dehumidifier without the drain insert can lead to condensate leaks. See FIGURE 3.    LEVELING
A level surface is required to ensure proper drainage from the dehumidifier. Refer to top mounted bubble level and adjust position until bubble is within the outer circle.

CONDENSATE PAN, CONDENSATE PUMP AND FLOAT SWITCH
A condensate pan is recommended when locating in or above a finished space or suspending over the canopy. 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 4. Overflow safety switches on condensate pumps can be wired to the Float Switch terminals in a similar fashion.

MODEL A77 – REMOTE CONTROL AND WIRING

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. Installing 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 a 4-wire 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 5 and tighten to secure.
4. Restore dehumidifier power. There is a delay of three minutes after restoring power before the dehumidifier will respond to the control.
5. Set up the dehumidifier to ENABLE REMOTE control as shown on page 7.
6. See USING THE MODEL A77 OR EXTERNAL CONTROL on page 7 for start up instructions.

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. Press the ON button on the Model A77 to turn on the control. The UP/DOWN arrow buttons are used to set the desired humidity setting. At all other times, the Model A77 will display the measured humidity level. Reference the Model A77 Installation and Operating Instructions for set-up.
ALTERNATE EXTERNAL CONTROLS
Alternatively, use any other humidity control system as long as it has a dry contact, normally open output dedicated to controlling the dehumidifier.
When using an external control, set up the dehumidifier to ENABLE EXTERNAL control as shown on page 7. Reference the installation literature provided with the alternative control for wiring, set-up and operating details.

SYSTEM SET-UP & CHECKOUT

Skip set up and proceed to INSTALLER TEST MODE on page 8 unless:

• A Model A77 or other external control is to be installed
• Changing the air sampling rate

1. Make sure the wire access cover has been snapped back onto the on-board control.

2. Plug unit in and turn power switch to ON.

3. The on-board control screen should display OFF. NOTE: If the display backlight is not on, the first button press (any button) will only turn on the backlight. Press the button a second time to achieve function.

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

5. Navigate through the following screens to set up the dehumidifier for the installed application.
   Use the UP or DOWN buttons to select items and use MODE to switch to the next set-up option. To exit installer set-up, all options must be scrolled through using the MODE button.

If using a Model 8800 series thermostat or alternate control as an external control, use the UP or DOWN button to select ENABLED, then press MODE to go to the next screen.  AIR SAMPLING
Use the UP or DOWN button to adjust how frequently the  dehumidifier samples the air todetermine 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. RH OFFSET
An offset can be applied to the on-board humidity reading to avoid discrepancies with other humidity measuring devices in the home. Use the UP or DOWN button to select an offset from -5% to 5%. Press MODE to exit the installer set-up screens. INSTALLER TEST MODE
If everything is properly wired, the dehumidifier and all of the wired components will turn on and off during Installer Test Mode to demonstrate that all are properly operating. Installer Test Mode lasts for four (4) minutes. If the ON/OFF button is pressed during test mode, the dehumidifier will exit Installer Test Mode and return to the OFF screen.
DEHUMIDIFICATION ONLY
If the dehumidifier is not already OFF, press the ON/ OFF button to turn it off.  Press and hold the ON/ OFF button and MODE buttons for 3 seconds. The measured humidity, AIR SAMPLING and TEST will show on the display. After three (3) minutes the dehumidifier compressor will turn on and DEHUMIDIFYING will replace AIR SAMPLING on the control screen. After one minute of compressor operation, all outputs will turn off and DONE will blink for 3 seconds and then return to the OFF screen.

START UP AND SEQUENCE OF OPERATION

USING THE DEHUMIDIFIER CONTROL

1. Press the ON/OFF button to turn the dehumidifier control ON. The display will show the current setting, and the dehumidifier blower will turn on  to start sampling the air.
