MAINTENANCE

WARNING: To reduce the risk of electrical shock and fire please observe the following instructions. Cleaning the Unit regularly will help to maintain its efficiency.

• Always unplug the cord before moving, servicing or cleaning.

SAVE THESE INSTRUCTIONS

The DH76 Dehumidifier reduces humidity in enclosed structural environments by removing water vapor from the air. With proper use, the DH76 can help to dry out damp structural materials, insulation, contents, and maintain a healthy level of humidity. Using the DH76 may also prevent secondary damage caused by high humidity.

SETUP DRAIN HOSE

The DH76 condensation pump connects to a plastic drainage hose. This hose is equipped with a quick- connect fitting for quick attachment to the provided 25 ft. (7.5 m) drain hose. Unwrap the entire hose and place the unattached end in a sink, drain, bucket or outdoors – anywhere that water can drain out safely. If you use a bucket or other container for water collection, check it regularly to prevent overflows.

NOTICE: Uncoil and straighten the entire drain hose. Do not leave any part of the hose coiled and do not place the end of the hose higher than 17 ft. (5 m) above the bottom of the unit. Also check for kinks or other obstructions that might restrict the flow of water. Obstructions may cause a water backup and result in overflows.

DISPLAY MODES

When unit is first plugged in to AC power, the control panel display will briefly cycle through a series of readouts. This is part of the unit’s self- diagnosis procedure and no user intervention is required.

NOTICE: The DH76 must be plugged into a 120VAC/ 60Hz outlet rated for at least 10 amps. Always plug the cord firmly into the unit first, and then plug the other end into a suitable wall outlet.

CONTROL PANEL

Runtime| Shows Job hours & life hours| STATE| Shows the state of the dehumidifier

HUMIDISTAT SETTING

The default operating mode keeps the dehumidifier running at its maximum capacity. This is ideal for most restoration application. To control humidity at a specific level, described below:

1. Press MENU once, and screen shows as FIG A, Press SET once so the screen shows as FIG B, with an arrow pointing at the line Moisture line.
2. Press SET to adjust the target Moisture, Each press of the button increases the setting by 5% increments, cycling through 90%RH and starting again at 0%RH.
3. Press MENU once to confirm you %RH, and then two more times to return to the main screen.

TEMPERATURE SETTING

To change unit of temperature, described below:

1. Press MENU once, and screen shows as FIG C, Press SET once, and then MENU once, so the screen shows as FIG D, with an arrow pointing at the Temperature line.
2. Press SET to select Fahrenheit or Centigrade.

AFTER THE JOB

To reduce the possibility of drips when moving the unit, follow these additional steps to ensure that all water is removed from the unit.

NOTICE: To ensure the condensate tank empties completely while purging, make sure the unit is positioned horizontally on a flat surface.

1. Gently rock the machine to ensure any water remaining on interior surfaces falls into the sump area.
2. Press the PUMP key. When the purge cycle is complete, turn the unit off.
3. Remove the external drain hose, drain it carefully, coil it and secure it with one of the Velcro straps provided on the side of the unit.
4. Unplug power cord from power supply and from base of the machine, coil neatly, coil it and secure it with one of the Velcro straps provided on the side of the unit.

TRANSPORTATION AND STORAGE

NOTICE: Handle the unit carefully. Do not drop, throw, or place the unit where it could fall. Rough treatment can damage this equipment and may create a hazardous condition or void warranty.

• Do not expose the control panel to moisture, snow or rain.
• Protect from freezing.
• Store and transport securely, and in the upright position, to avoid damaging of internal parts.
• Secure during transport to prevent sliding and possible injury to vehicle occupants.

MAINTENANCE SCHEDULE

WARNING:  ELECTRIC SHOCK HAZARD. Unplug unit before cleaning or servicing.

WARNING: Risk of dust and contaminants exposure. Use of respirator mask and gloves is recommended. If unit has been exposed to potentially dangerous contaminant, clean thoroughly and sanitize before reuse.

NOTICE: The unit is fitted with sensitive electronic sensors. Protect the sensors and their lead wires from damage and do not expose them to water or cleaning solution.

Before Each Use: Inspect the electrical cord for damage. Look for fraying, cuts, etc. Replace the cord if you find any damage. Inspect, vacuum or replace filter. Monthly Inspect coils. Clean when dust accumulation is visible. In normal use, dust can accumulate and can restrict airflow, reducing performance and causing the unit to overheat. Use a vacuum cleaner with a brush tool and a soft cloth to remove any debris. Take care not to damage any interior components. To maintain appearance, wipe interior surfaces with a damp cloth.

Clean Pump Check Valve and Basin: If the unit displays the message “STATE PUMP”, which means the pump may be blocked, check valve and pump basin may need to be cleaned. This operation must be performed by a qualified technician. Unplug the dehumidifier before

Cleaning:  Remove grills and cover. Remove screws from pump base and lift out pump. Wipe out pump basin with a damp cloth. Inspect the pump base for build-up of debris and clean if needed. Unthread barbed fitting with check valve and rinse fitting and check valve with clean water. Reinstall check valve into barbed fitting and install the barbed fitting into pump. Do not over-tighten. Reinstall pump in base. Reinstall cover and grills.

Clean Coils: With the cover removed, inspect both coils. If excessive dust and debris is present, vacuum thoroughly and/or clean with coil cleaner. This operation must be performed by a qualified technician.

SYSTEM MESSAGES

The DH76 control system constantly monitors internal operating conditions. If the system detects a problem, the state row will change to an ERROR message instead of RUN/OFF. If the display shows an ERROR message, first unplug the unit and then plug it back in. This will usually reset the electronics, and the unit will begin operating normally. If the ERROR message reappears, refer to the explanation and solution shown below.

Control Panel Explanation and Solution Message     Meaning

STATE COMP| Compressor may not work, Check compressor cable for proper connection. If error persists, contact service.
STATE: MOIS| Check inlet Temp/RH sensor for proper connection. If error persists, contact service.
STATE: TEMP 1| Check inlet Temp/RH sensor for proper connection. If error persists, contact service.
STATE: TEMP 2| Check outlet Temp/RH sensor for proper connection. If error persists, contact service.
STATE: PUMP| Check for obstructions in drain hose. If clogged, remove hose from unit and blow hose out with compressed air. Inspect and clean the pump check valve and pump basin.
