IV. operating instructions

Use the main control knob (Figure 2) on the outside of the unit to set the dehumidifier dryness setting. Start with a “Normal” setting for most installations. Moving the knob clockwise to “more” will make conditions drier. Moving the knob toward “less” allows for higher moisture levels.

Based on the indoor temperature, use the following table to determine the control knob setting to reach the desired RH value. The dehumidifier will work to achieve these values.

III.installation instructions

1.Install the drain line

NOTE: The provided condensate trap must be installed to the dehumidifier.

•Verify the bottom of the dehumidifier is 2 1/2” or higher above the floor.

•Insert the high side of the trap into the drain outlet (water flow direction is shown on the trap and should point away from the dehumidifier)

•If there is not enough room to install the trap directly into the dehumidifier, use the provided 90° elbow to position the trap close to the dehumidifier

%RH (± 5%) based on Control Knob Setting and Indoor Temperature

Control Knob			Indoor Temperature
	Setting	65°F	70°F	75°F	80°F
1	– “LESS”		84%	71%	60%
2		86%	73%	61%	52%
3	– “NORMAL”	74%	63%	53%	45%
4	– “NORMAL”	64%	54%	45%	39%
5	– “NORMAL”	55%	46%	39%	33%
6		47%	39%	33%	28%
7	– “MORE”	40%	34%	28%	24%

Example: At an indoor temperature of 75°F with a dehumidifier control knob setting of 3, the dehumidifier will work to achieve an RH value of 53%.

NOTES:

1.%RH values are ±5% and are to be used as a GUIDE ONLY for initial set-up.

2.Indoor Temperature is measured at the inlet to the dehumidifier.

IMPORTANT: The bottom of the trap outlet must be at least 1/2 inch below the bottom of the dehumidifier to ensure a proper drainage slope (see Figure 1).

•After verifying that the trap is in the proper orientation, use PVC primer and cement to secure the trap in place. Cement the supplied threaded coupler to the outlet of the trap.

•Screw the supplied hose barb fitting into the coupler and attach the supplied 1/2 inch I.D. drain hose. Route the hose to the nearest drain.

IMPORTANT: To prevent a pressure lock within the drain line, the tube must be installed with a constant downward slope.

Prime the drain system by filling the drip pan in the dehumidifier with water until flow is completed to the drain.

2. Plug the dehumidifier directly into an outlet – do not use an extension cord.
NOTE: A 15 amp circuit is required for proper operation.
3. Turn the ON/OFF switch to ON.

V. Troubleshooting guide

SYMPTOM	TROUBLESHOOTING PROCEDURE / POSSIBLE REASON
	• Reheat of outgoing air will cause a temperature increases across the dehumidifier
Dehumidifier is producing hot air	• Unit will possibly run continuously initially. After unit has “dried” home, dehumidifier
	will cycle, reducing load
	• Unit will need time to “dry” materials in home before effectively changing RH.
Dehumidifier not adequately dehumidifying	• Compressor is not turning on
	• System undercharged
Dehumidifier is not draining properly	• Check condensate trap to be sure it is clear
	• Check drain line for continuous slope
	• Follow all of the system checkout procedures. Make sure power switch is on!
Dehumidifier does not run	• Check that circuit breaker is not tripped. The dehumidifier requires a minimum of
	8 amps. The dehumidifier should be placed on its own dedicated 15 amp circuit

LED CODES

Green LED

Activity		Status
ON Solid		Compressor ON
Blinking 1 second on, 1 second off		Sampling
Blinking 1/2 second ON, 1/2 second OFF		Defrosting
Red LED
Activity		Status
1	Blink every 5 seconds	There is an error with the RH sensor
2	Blinks every 5 seconds	The board temperature sensor is opened or shorted
3	Blinks every 5 seconds	The Model 70 Living Space Control fails to respond after 3 consecutive attempts
4	Blinks every 5 seconds	The refrigerant charge has been detected as low
5	Blinks every 5 seconds	The temperature sensor is out of the operating range
6	Blinks every 5 seconds	The internal frost sensor is opened or shorted
7	Blinks every 5 seconds	The float switch has opened

Test Mode

At the end of test mode (3 minutes of DEH Fan + 1 minute of Compressor ON & DEH Fan), the Red and Green LEDs will turn ON and OFF alternately until the knob has been turned away from “TEST”.
