Page 3 of 16 P/N 780107801 06/24 RevB ABOUT FIELD CONTROLS DEHUMIDIFIERS Field Control Dehumidifier controls the humidity level in your entire home and ensures the home is maintained at the proper humidity levels through high performance and efficiency. The blower inside the unit draws air into the cabinet through a washable pre filter and Merv 10 filter prior to having the moisture removed and released back into the home. P/N 780107801 06/24 RevB Page 4 of 16 BENEFITS OF MAINTAINING THE IDEAL HUMIDITY LEVEL The optimal humidity range defined by industry experts and health professionals is between 40-60% on an average annual basis. The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHREA) state that when indoor humidity exceeds the 60% threshold the home is more susceptible to bacteria, viruses, mold, and mildew. Dew points and relative humidity (RH) affect the way your body senses temperature. Higher humidity levels cause the air to feel much hotter that the actual temperature. When RH is maintained properly, your cooling equipment may not run as often because dehumidified air feels cooler.

When relative humidity goes above the selected set point, the dehumidifier will energize. A blower inside the dehumidifier draws the air into the cabinet where it passes through a washable prefilter and a Merv 10 filter. The air is then drawn across an evaporator coil, which is cooler than the dew point causing the moisture to condense on the coil and drip down to the pan and out the drain. The air is then moved over another coil to be reheated before it is sent back into the home. The air leaving the dehumidifier will be warmer and drier that the air that entered. DEHUMIDIFIER LOCATION · Electrical service access and drain cleaning will require the removal of the side panel. Allow applicable space for service on the side of unit. · Filters can be accessed from either side of the unit. Allow enough space for filter to remove and reinstall the filter. · If unit is going to be in area not readily accessible (Attic or Crawl Space) consider a control such as the Field Controls Remote Control Model WHD1-RCK which can be mounted in the living space and wired to the unit. · The area where the dehumidifier is located should be sealed with a vapor barrier. · If the unit is installed in a crawl space, all vents should be sealed. · For proper ventilation, do not position the inlet or discharge against a wall. The inlet needs a minimum of 12" clearance and the discharge require a minimum of 36" clearance. · For the best air diffusion, install the unit so that a side panel faces the wall. · Field Controls dehumidifiers are only intended for operation when the unit is upright and level with the feet on the ground (unless using a Field Controls Hanging Kit). P/N 780107801 06/24 RevB Page 6 of 16 Applications Above a Finished Space ALWAYS ADD A CONDENSATE PAN UNDER THE DEHUMIDIFIER WHEN LOCATING IT ABOVE A FINISHED SPACE. Make sure to adhere to local codes regarding draining of the condensate pan. If a condensate pump is needed, make sure the pump is located inside the pan as well. Install a float switch in the condensate pan and use the overflow wires/terminals on the condensate pump to turn off the dehumidifier if overflow should occur. See Wiring Diagram. SET UP - ALL APPLICATIONS 1. Place the dehumidifier on a level surface. a. Do not place unit directly on vapor barrier. b. NOTE: If the unit has been turned or flipped so that the compressor did not remain upright, place unit on level surface and wait a minimum of 2 hours before proceeding. 2. Duct Collars c. Attach duct collars to inlet and outlet of dehumidifier with included screws. While not needed for freestanding installation, they can be used to help reduce the sound level. d. Maximum recommended combined duct length (Inlet and Outlet) is 10'. e. Note that for 60 / 85-pint units there will only be 6 screws provided as 2 can be reused from the unit. 3. Set up the drain line. f. The drain line should be routed to a suitable drain option. g. THE DRAIN MUST FLOW DOWN WITH NO LOOPS OR DIPS h. Recommended Drain Option- Transition to PVC Pipe i. Cut a piece of 3/4" OD PVC that is approx. 6" long. ii. Attach PVC + elbow to a 3/4" OD piece of PVC to drain. Keep the length of PVC as short as possible. iii. Insert the open end of the dehumidifier drain tube into a 6" piece of PVC so that it does not extend into elbow fitting. iv. For a proper flow, a minimum downward slope of 1" per 10' run is required. v. Support the PVC tubing so that it maintains a smooth downward flow to drain. 4. Plug unit into a dedicated 15-amp GFCI protected outlet. 5. Auxiliary Terminals: i. Auxiliary Terminals A5/A6 (Normally Open Accessory) i. The A5/A6 on the terminal strip can be used as a safety switch for an external float switch or condensate pump with Normally Open Contacts. ii. If an E4 error occurs immediately, remove the wires from terminal strip and unplug the dehumidifier. Plug in dehumidifier with nothing attached to terminal strips. If E4 occurs again, contact Field Controls customer support. If not, see step three. iii. Double check that external device is intended to be Normally Open. You may need to switch to Normally Closed (see below). Note that you may need to unplug the unit to reset the error code. Page 7 of 16 P/N 780107801 06/24 RevB j. Auxiliary Terminals A8/A9 (Normally Closed Accessory) i.

If an E4 error occurs immediately, remove the wires from terminal strip and unplug the dehumidifier. Plug in dehumidifier with nothing attached to terminal strips. If E4 occurs again, contact Field Controls customer support. If not, see step three. iii. Double check that external device is intended to be Normally Open. You may need to switch to Normally Closed (see below). Note that you may need to unplug the unit to reset the error code. iv. Double check that external device is intended to be Normally Closed. You may need to switch to Normally Open (see above). Note that you may need to unplug the unit to reset the error code. SET UP - HVAC SYSTEM This dehumidifier will automatically detect external controls. It is NOT necessary to adjust the dehumidifier display panel or control board. Once connected to the external controls, the dehumidifier buttons will no longer be active. NOTE: Check local building codes prior to connecting the dehumidifier to the HVAC system. P/N 780107801 06/24 RevB FIGURE 3: WIRING DIAGRAM Page 8 of 16 1. Connect controls per diagram on previous page (Figure 3). 2. A 24VAC input to terminal #A3 and #A4 from the HVAC controller will turn the machine "on". The power light on the dehumidifier display will light up and the two-character LED display will read "CC" for central control. The unit will run until the HVAC controller has met the desired humidity level. 3. When the humidity level is satisfied, the HVAC controller will remove the external 24VAC supply signal. This will cause the power light on the dehumidifier display to turn off and the 2 character display will now read " - - ". 4. If a power outage occurs, the dehumidifier will return to the state it was in and cycle on and off based on the 24VAC external control signal. 5. If desired, the dehumidifier can turn the HVAC fan on. To do so, install a jumper on the dehumidifier terminal strip between #A3 and #A2. Connect terminal #A1 back to the HVAC controller as shown on previous page (Figure 3). The fan will come on whenever the dehumidifier is running. HVAC CONNECTION OPTIONS 1.
