Frequently Asked Questions - D35B1A Friedrich

How often should I clean the filter on my D35B1A dehumidifier?

It is recommended to clean the filter every 2 weeks of operation. A dirty filter can reduce efficiency. Remove the filter and rinse with warm water, then allow it to dry completely before reinstalling.

Can I use the dehumidifier in a basement with a floor drain?

Yes, the D35B1A supports continuous drainage. Use a standard garden hose (not included) connected to the drain port. Ensure the hose slopes downward to allow gravity flow.

What does the 'Full Bucket' indicator mean?

The indicator lights up when the water bucket is full or not properly positioned. Empty the bucket and reinstall it securely. The unit will resume operation automatically after the bucket is replaced.

Why is my dehumidifier blowing warm air?

This is normal. The dehumidifier extracts moisture and releases dry, slightly warmed air as a byproduct of the refrigeration process. The temperature rise is typically 10-15°F above room temperature.

What is the maximum humidity level I can set?

The built-in humidistat allows setting between 30% and 80% relative humidity. The recommended comfort level is between 45% and 55%.

How do I defrost the unit in cold weather?

The dehumidifier has an automatic defrost cycle. When operating below 65°F, it may cycle off periodically to defrost the coils. Do not attempt to manually defrost with hot water or tools.

Can I leave the dehumidifier running while I am away?

Yes, if properly set up with continuous drainage and a clean filter. Ensure the unit is on a level surface and away from obstructions. The automatic shut-off and adjustable humidistat provide safe operation.

What should I do if the unit displays an error code?

Refer to the troubleshooting section of the manual. Common codes include: E1 (humidity sensor error), E2 (defrost sensor error). Unplug the unit for 5 minutes and restart. If the error persists, contact Friedrich customer support.

How much water does the bucket hold before needing to be emptied?

The water bucket holds approximately 8.8 pints (4.2 liters). The unit will automatically shut off and alert you when the bucket is full.

Is the D35B1A Energy Star qualified?

Yes, this model is Energy Star certified, meaning it meets strict energy efficiency guidelines set by the U.S. EPA. It uses less energy than standard dehumidifiers, saving you money on utility bills.

INSTALLATION INSTRUCTIONS

Follow the steps below for unpacking and set up your unit.

STEP 1. Remove unit from carton and inspect.

STEP 2. Remove accessories from drain bucket.

STEP 3. Set up unit in position with adequate clearance. Installation of unit is complete.

Allow at least 8 inches of space all around the unit and at least 24 inches of space above the unit.

OPERATION INSTRUCTIONS

WARNING
	Electrical HazardsDo not fold power cord as shown at left.
	Make sure the plug is placed fully and firmly into the receptacle.
	Do not use multiple sockets as shown at left.
	Make sure the plug is clean.
	After turning the unit off please take plug out of the receptacle.
	Do not have wet hands when connecting the power plug.
	Do not pull the power cord to avoid a broken cord, which can lead to danger.

Start Operation

STEP 1. Place the unit in an upright position on a flat, steady, stable and heat resistant surface. Make sure there is nothing flammable or heat sensitive within 39 inches. Operating the product in any other position could cause a hazard.

WARNING

Electrical Shock Hazard

Make sure your electrical receptacle has the same configuration as your dehumidifier's plug. If different, consult a Licensed Electrician.

Do not use plug adapters. Do not use an extension cord. Do not remove ground prong.

Always plug into a grounded 3 prong oulet. Failure to follow these instructions can result in death, fire, or electrical shock.

STEP 2. Insert the plug into a suitable wall socket. The dehumidifier is suitable for operation on an electricity supply having the same voltage as that shown on its rating label.

STEP 3. Make sure the Drain Bucket is correctly placed in the proper position (See Figure 5). (After switching the unit 'ON" for the first time, if the Bucket Full lamp illuminates, just pull out the drain bucket; check to ensure that the float lever is able to move freely, then return the drain bucket to the correct position).

Figure 5

FRD004

When Bucket Full Lamp Is On

When the drain bucket is full, the Bucket Full lamp will illuminate and the unit will stop operating. The drain bucket should be carefully removed from the unit by sliding it outwards (See Figure 6) and should be emptied. Then place the empty drain bucket back to its proper position, (See Figure 7) the unit will start operating and run normally.

Figure 6

PLEASE USE BOTH HANDS TO CAREFULLY EMPTY THE DRAIN BUCKET.
FRD005

Defrost

When the unit is operated in low temperatures (less than 54 °F the surface of the evaporator will accumulate a layer of frost which will reduce the efficiency of the dehumidifier. When this happens the unit will go into periodic defrost mode automatically. The Defrost Lamp will illuminate on control panel, this is quite normal (See Figure 7).

The dehumidifier will operate in temperatures down to 41 °F. The time it takes to defrost may vary. If the unit freezes up it should be turned off at the power supply for a few hours and then re-started. If the room temperature remains below 41 °F the unit should be switched off. It is not recommended to use the dehumidifier in temperatures below 41 °F.

CONTINUOUS DRAINAGE

To save having to periodically empty the drain bucket, this unit can be configured for continuous drainage. You can use the supplied drain hose to connect to the continuous drainage connector (See Figure 18).

Unscrew and remove the drain cover at the rear of the unit (See Figure 19). Remove the soft rubber stopper. Put it into the drain bucket for safe keeping (See Figure 19).

Insert the drain hose through the hole of the drain cover. Then connect the drain hose to the drain port (See Figure 20).

Tighten the drain cover in clockwise direction onto the rear of the unit (See Figure 21).

Place the bucket in its original location (See Figure 22).

Continuous Drain Hose Routing

When using the function of continuous drainage, the drain hose must be placed horizontally below the drainage hole (See Figure 23).

You must avoid uneven ground and folding the hose (See Figure 23).

Figure 23

Continuous Drainage using Built-In Pump

Installation:

STEP 1. Connect the supplied water hose to the drainage key.

STEP 2. Connect the drainage key and water hose (1) to the drain pump outlet (2) on the rear panel.

STEP 3. Lead the other end to a suitable location for drainage, like a drain or sink and insert the plug into the water drain.

The maximum distance and the rise may be 15 ft from the unit. Exceeding this distance may damage the unit or cause leaks. When the unit's drain bucket capacity reaches a certain water level, it will drain automatically (See Figure 24).

Dismantle:

Press the drain release button (3) on the unit rear panel. The automatic drainage key will pull out (See Figure 24).

Figure 24

FRD027

NOTICE

The rubber drain plug must be inserted in the continuous drainage outlet (4) for built-in pump feature to work.

Removing the rubber drain plug will cause the condensation to exit through the continuous drainage outlet instead of the drain pump outlet.

MAINTENANCE

For safety reasons, make sure the unit is unplugged before servicing or cleaning.

Cleaning the shell

STEP 1. Wipe the shell with a clean, soft cloth.

STEP 2. If the unit is very dirty, use mild detergent then wipe off the detergent with half dried cloth.

Cleaning the air filter

The purpose of the air filter is to filter dust and other materials from the air. If the filter is blocked by dust the electricity usage will be greater than normal. For optimal moisture removal and efficiency, clean the filter every two weeks.

Cleaning Steps

STEP 1. Pull the air filter out gently (See Figure 25).

STEP 2. Clean the air filter with a vacuum cleaner or wash it with clean water and dry with a dry cloth (See Figure 26).
