I. PRINCIPLE OF OPERATION

The purpose of the Aprilaire® Dehumidifier is to keep humidity in the house at acceptable limits to reduce the unwanted effects of high humidity. The dehumidifier measures the condition of the house air to decide when to run.

INSTALLER – PLEASE NOTE!

TROUBLESHOOTING GUIDE

SYMPTOM	TROUBLESHOOTING PROCEDURE/POSSIBLE REASON
	• Reheat of outgoing air willcause 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

1.INSTALLATION MUST CONFORM TO ALL APPLICABLE STATE OR LOCAL CODES.

2.A DEDICATED 15 Amp circuit is required for proper operation of the dehumidifier. If a dedicated circuit is not available, use a lightly loaded circuit. Do not use an extension cord.

3.For protection of the compressor, unit must be transported and installed in an upright position. If the unit was shipped or stored on its side, a 24 hour settling period is required before running the unit.

4.Note the dehumidifier is not intended to be used in pool applications.

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

ADJUSTING THE DEHUMIDIFIER SET POINT

WARNING

•120 volts may cause serious injury from electric shock.

•Unit weight and dropping may cause personal injury or equipment damage. Handle with care.

SPECIFICATIONS

Use the main control knob (Figure 1) on the outside of the
	FIGURE 1
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

II. OPERATINGINSTRUCTIONS

The dehumidifier dryness can be set from “1” or “LESS” to “7” or “MORE” based on desired comfort level. Most installations should be initially set between “3” and “5” or “NORMAL” setting; however this can be adjusted to your individual needs.

DRAIN LINE

The included condensate trap must be installed to the Model 1710. Use PVC cement to connect the trap to the drain outlet on the Model 1710. The drain outlet is located near the On/Off toggle switch. Note orientation of trap prior to cementing. The high side of the trap mates with the Model 1710. Complete the assembly by piping the trap to the drain. The trap must be primed with water prior to start-up.

SYSTEM CHECKOUT

1.Rotate the main control knob clockwise to the “TEST” position

2.If all is set up properly, the dehumidifier blower will turn on. The compressor will turn on after the dehumidifier blower has run for 3 minutes, then both the compressor and blower will run for 1 minute. The dehumidifier and compressor will then shut off (“TEST” mode only).

3.If the dehumidifier blower does not activate in TEST mode, refer to the Troubleshooting Guide.

III. MAINTENANCE

AIR FILTER

Under normal circumstances, the filter in the dehumidifier should be cleaned or replaced once a year. A clean filter is necessary to prevent damage to the dehumidifier and allow it to function at full capacity. To remove the filter, first unplug or disconnect power to the dehumidifier, then remove the air filter via the access panel on the side of the dehumidifier. To clean, flush with warm water and detergent solution. After a clean or new filter is reinstalled, replace the access panel and reconnect power to the dehumidifier. The replacement filter for the dehumidifier is Model 4510 and is available from most HVAC contractors in your area or Aprilaire.com

DRAIN

The drain trap or outlet should be checked and cleaned of debris annually.

NOTE: The drain trap needs to be primed with water prior to start-up and after extended periods of unit shut down (winter months).
