SAFETY INSTRUCTIONS Be sure to read and understand all safety precautions and instructions before installing and operating the unit. ! WARNING The following precautions indicate a hazardous situation that, if not avoided, could result in death or serious injury. • Always disconnect electrical power before starting installation or servicing to avoid electric shock. • Always wear glasses/goggles and gloves when installing the unit. Sharp edges may cause serious cuts.
2. Use the ON/OFF Button (see Figure 2) on the control panel to turn the dehumidifier ON. The first press of a button will turn on the display light, so if the display was dark, you might need to press it again. Once ON, the display will show the current dehumidifier setting. ENERGY SAVINGS TIPS ENERGY SAVINGS TIP #1: Adjust the humidity setting to be as high as is comfortable to reduce dehumidifier run time. If it feels clammy or “smells musty,” lower the humidity setting.
CLEANING THE DRAIN 1. With the filter door on the drain side of the dehumidifier removed, reach in and pull out the drain insert using the finger loop (see Figure 6). 1 90-2607 Figure 6: Drain Cleaning 1 - Drain Insert 2. Clean the drain pan and drain insert using a mild detergent. 3. If the drain has a capped tee or elbow to allow cleaner to be poured directly in the drain, remove the cap and pour approximately one cup of vinegar into the tube (see Figure 7).

REPOSITIONING THE CONTROL FOR THE APPLICATION Locate the onboard control panel on the top of the dehumidifier or at the front of the dehumidifier if the control panel cannot be seen/accessed in the top orientation. It may also be rotated 180 degrees in either orientation (see Figure 10). 1 2 INSTALLING THE DUCT COLLARS • Use the screws in the parts bag to attach the duct collars to the inlet and outlet of the dehumidifier. The outlet collar has a backflow damper.
INSTALLING THE DEHUMIDIFIER LEVELING AND RAISING THE DEHUMIDIFIER DEHUMIDIFIER LOCATION • Electrical service access and drain cleaning will require the removal of the electrical service side panel (see Figure 12). Allow sufficient space for service on this side of the unit. • The filter can be removed from either side of the dehumidifier. Allow sufficient space for the filter to be removed and reinstalled.
INSTALLING DUCTWORK INSTALLING THE DRAIN Using Hard Pipe: • Install a 3/4" PVC slip x 3/4" MNPT PVC fitting to the dehumidifier and use 3/4" nominal PVC Schedule 40 pipe to run the condensate line to the nearest floor drain or to an outside location that slopes away from the building. • Always maintain a constant downward slope in drain piping. Ensure that drain tubing does not interfere with removal of the side panel or filter door. • Do not use metal fittings and only hand-tighten threaded fittings.

DUCTING THE DEHUMIDIFIER OUTLET TO THE HVAC SYSTEM WITH DEDICATED DEHUMIDIFIER INLET REGISTER • To direct dehumidified air away from a potentially wet AC coil: 4 2 − Duct to the supply side of the HVAC system for air handler applications where air is pulled through the AC coil (see Figure 16).
WIRING TO THE HVAC SYSTEM When the dehumidifier is ducted to the HVAC system, it is recommended that it also be wired to the HVAC system as shown in Figure 20. If ducted to the HVAC system in a return-to-return configuration, the dehumidifier must be wired to the HVAC system to prevent short-circuiting dehumidified air directly back to the dehumidifier inlet.

SETTING UP REMOTE CONTROL – CRAWL SPACE/SEALED ATTIC If wiring to a Model 76 for remote control (see page 17 for details) press the s or t button to ENABLE. SETTING UP VENTILATION See page 13 for details if using the dehumidifier for ventilation. SETTING UP ZONING See page 14 if zoning the dehumidifier. 16 English SETTING UP EXTERNAL CONTROL If wiring to an external control (see page 12 for details) press the s or t button to ENABLE.
APPLYING AN RH OFFSET An offset can be applied to the onboard humidity reading to avoid discrepancies with other humiditymeasuring devices in the home. Use the s or t button to select an offset from -5% to 5%. Press the MODE button to exit the installer setup screens. USING A MODEL 76 AS A REMOTE CONTROL 1. Press the ON/OFF Button to turn the dehumidifier control ON. The display will show the word REMOTE to indicate that a remote control is to be used to control the dehumidifier. 2.
immediately after the call has been satisfied. When an external control is installed, the Secondary Zone will be sampled once per hour if there has not been a call for dehumidification from the Primary Zone. TROUBLESHOOTING DIAGNOSTIC CODES When an error occurs, the Diagnostic Code along with SERVICE REQUIRED will be displayed on the control screen. Technical support is available Monday through Friday 7:00 a.m. to 5:00 p.m. CST at (800) 334-6011.
Table 1: Diagnostic Codes Diagnostic Code E4 Failure Mode Insufficient Capacity Action Reset 6. Allow the fan and compressor to run for approximately 10-15 minutes and then enter diagnostic test mode by simultaneously pressing the s button and MODE button for 3 seconds.
Table 2: Troubleshooting Guide Symptom Possible Reason Dehumidifier does not turn on/run. No power to unit. Troubleshooting Procedure • Check that the dehumidifier is plugged in. • Check that the control is turned ON. • • Dehumidifier blower is running but with little or no airflow. Dehumidifier blower is running but compressor is not. When zoned, the dehumidifier damper does not open in INSTALLER TEST mode. 20 English Check that the power switch is turned ON.
Table 2: Troubleshooting Guide (Continued) Symptom The ventilation damper does not open when the HVAC fan is active. Possible Reason Troubleshooting Procedure Cycle time has been met. • The damper will not open if the ventilation time has already been met. ODT error or outdoor air outside of ODT range. • Check that the ODT is wired correctly to the dehumidifier control board and connections are secure. • • Dehumidifier is not draining properly. Drain line blocked or unit not level.
