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" 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.

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.

FIGURE 7 – LEVEL THE UNIT

CONDENSATE PAN, CONDENSATE PUMP AND FLOAT SWITCH

A condensate pan is recommended when suspending the dehumidifier 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 8. Overflow safety switches on condensate pumps can be wired to the Float Switch terminals in a similar fashion.

MODEL A77 – REMOTE OR EXTERNAL CONTROL AND WIRING

NOTE: Use 18-22 AWG wire for control wiring.

The internal dehumidifier control can be used to control humidity, or a remote Model A77 Control or other external control (see below) can be wired to the dehumidifier.

FIGURE 9 – MODEL A77 REMOTE CONTROL WIRING

Without an external control, the dehumidifier will turn on its blower for three minutes every 15, 30 or 45 minutes depending on how often the

unit is set to sample the air. The dehumidifier can also be set to sample the air continuously (see AIR SAMPLING on page 8). The blower is turned on to get a representative reading of the room relative humidity. A shorter sampling period reduces the duration of any humidity spikes

MODEL A77 CONTROL

that might occur when neither the air conditioning nor the dehumidifier are running. To reduce energy consumption the sampling time can be set to a longer period.

Installing an A77 or other 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.

B C/R/+ DH DH

90-1860

To install the Model A77 control:

1. Turn off power to the dehumidifier using the ON/OFF switch.

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 9 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. Go to REMOTE CONTROL on page 7 to configure the dehumidifier control to respond to an 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.

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 & Operating Instructions for set-up.

ALTERNATE EXTERNAL CONTROLS

A Model 8840 thermostat can be used to control the HVAC equipment, and for dehumidifier control in place of the Model A77. The Model 8840 thermostat has Wi-Fi capability so the conditions in the room can be monitored at any time from any location. Additionally, up to four remote sensors can be mounted near the canopy and connected to a single thermostat. The four humidity measurements can be averaged and the thermostat will turn on the dehumidifier based on the averaged value.

Reference the 8840 Installation Instructions and Owner’s Manual for wiring, set-up and operating details.
