The Friedrich

C-90A Electronic

Air Cleaner

CAUTION:

Before operating

the unit

The Friedrich Electronic Air Cleaner is a self-contained console model consisting of a high voltage DC power supply, electronic cell, 3 speed fan, pre-ﬁ lter and activated carbon postﬁ lter in a rugged plastic cabinet.

It is designed to remove dust, tobacco smoke, pollen, bacteria and other airborne contaminants from the air. In just minutes, you will notice improvements in your indoor air quality as your Friedrich air cleaner begins the job of removing the billions of irritating microscopic particles from your home or ofﬁ ce. The activated carbon post-ﬁ lter also helps eliminate many objectionable indoor odors.

• Carry unit by handle indentations on side panels or carry from base, as the top removes for ﬁ lter maintenance and will not support the unit.

• Remove the plastic cover from the activated carbon ﬁ lter, and place the ﬁ lter with label facing out.

• Make sure the electronic cell is properly placed in the cabinet - airﬂ ow arrow on the end plate should be pointing toward the fan.

• Make sure that the top cover is securely in place.

• This unit is equipped with a three-prong (grounded) plug for your protection against shock hazards and should be plugged directly into a properly grounded three-prong receptacle.

DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR REMOVE THE GROUNDING PRONG FROM THIS PLUG.

• Electronic air cleaners should NOT be placed in any area where potentially dangerous gasses or vapors exist, nor should they be used in wet environments.

CONTROLS

All controls for the Friedrich electronic air cleaner are located on the top of the unit and are accessible through an opening in the top cover. The controls are: OFF, HI, MED and LOW. An indicator lamp lights when the cleaner is on and operating normally.

Generally, HIGH fan speed is used in extreme conditions for rapid cleaning; such as during or after a party where there were many smokers; or for larger areas to circulate the clean air in all areas of the room. MEDIUM and LOW settings are usually adequate to maintain a clean air environment.

At initial start-up, the indicator lamp may ﬂ icker on and off and is not cause for alarm. Should the lamp completely fail to come on, review the "BEFORE OPERATING" and "TROUBLESHOOTING" sections.

During initial use, “snapping” sounds may be heard. This is normal, and the unit may continue to make these noises during the ﬁ rst few days of operation. After this initial break in period, on ly an occ asional "snap" will be heard, indicating t he u nit is c leaning your air. NOTE: As th e air cleaner’s electronic cell becomes dirty, it will "snap" more frequently. When this occurs, you should wash the cell.

The best location for the air cleaner is a place closest to the source of tobacco smoke, dust or other indoor contaminants.

Position the unit so that the airﬂ ow around the intake and discharge grilles is not blocked. For best results, do not place the intake grille (rear) closer than eight (8) inches from a wall. Provide a clear, unobstructed path for the discharge air. The farther the discharge air travels, the greater the effectiveness of the air cleaner. For greater comfort, position the air cleaner so that the discharge air does not cause uncomfortable drafts.

Cleaning

To use a room air cleaner most effectively in rooms that share an open doorway or archway, position the unit near the common opening and direct the airﬂ ow into the adjacent room to promote good air circulation.

ECONOMICAL CLEAN AIR

The Friedrich electronic air cleaner costs no more to operate than a standard household light bulb. The beneﬁ ts from clean air far outweigh the low operating costs of continuous cleaning. Remember, the more you operate your electronic air cleaner, the cleaner your air will be.

IMPORTANT PRECAUTIONS

The collector plates of the electronic cell and the pre-ﬁ lter can become extremely dirty. With an excessive amount of contamination buildup on the collector plates and the pre-ﬁ lter, the electronic air cleaner’s efﬁ ciency decreases. Also, as dirt builds up on the ionizing wires, the charging process becomes less efﬁ cient.

To prevent this loss of efﬁ ciency, the electronic cell and pre-ﬁ lter must be cleaned regularly. How often will depend on actual usage. Cleaning will be more frequent if the air cleaner is operated continuously or under severe conditions.

Turn off and unplug air cleaner before opening top cover to remove electronic cell and preﬁ lter for cleaning. Always be careful when handling the electronic cell. Sharp edges and wires are capable of inﬂ icting wounds. Care should also be taken when cleaning because of extremely hot water and potentially harmful effects of detergents on your skin.

Cleaning

(Continued)

CLEANING THE PRE-FILTER

Remove the pre-ﬁ lter and shake out or brush off the accumulated dust and lint. If this is not adequate, a vacuum may be used or the pre-ﬁ lter can be cleaned with an all-purpose cleaning agent to remove tobacco smoke and cooking grease stains. A thorough rinsing is required after each cleaning. After cleaning, allow to dry and reinsert.

CLEANING THE CARBON FILTER

Occasionally, the carbon ﬁ lter will need cleaning. Use a stream of air or a vacuum to remove the dirt. THE CHEMICAL AND ODOR ABSORPTION CAPABILITIES CAN NOT BE RESTORED. When the carbon ﬁ lter can no longer remove odors from the air, it must be replaced. (See Carbon Filter Reorder Form packed with this unit or contact your nearest Friedrich dealer.) Under normal operating conditions the carbon ﬁ lter should be replaced every 3-6 months. THE CARBON FILTER MUST BE IN PLACE FOR THE AIR CLEANER TO OPERATE.

CLEANING THE ELECTRONIC CELL

The simplest method of cleaning the electronic cell is to use an automatic dishwasher. The dishwasher provides the correct cycle of wash, rinse and dry. Water temperatures normally found in dishwashers will not harm the cell.

1. After turning off the air cleaner, remove the cell and gently place on the dishwasher rack

with airﬂ ow arrows pointing up. In some dishwashers, it may be necessary to remove the top rack. BE EXTREMELY CAREFUL WHEN PLACING ON DISHWASHER RACK TO NOT DAMAGE IONIZER WIRES OR BEND COLLECTOR PLATES.

2. Use any available household dishwasher detergent recommended for use in your

appliance and follow manufacturer’s instructions.

3. Not all dishwashers may be capable of holding the electronic cell. Be sure to compare

the internal size of the dishwasher to the dimensions of the electronic cell (16" high x 12 1/2" wide x 4 1/2" deep.) All parts of the dishwasher must be able to move freely.

4. Take care to avoid damaging the cell when removing it from the dishwasher. GENTLY

LIFT THE CELL STRAIGHT UP TO PREVENT DAMAGE TO IONIZER WIRES AND COLLECTOR PLATES.

5. The cell may be hot when removing it from the dishwasher. Allow to cool or wear

protective gloves. Make sure that all water is drained off when removing the cell from the dishwasher.

6. If dirt stains or detergent residue remain after washing, it may be necessary to rewash

the cell or switch detergent.

7. The electronic cell must be COMPLETELY dry before replacing it in the air cleaner

for use.

Cleaning

(Continued)

ALTERNATE CELL CLEANING METHOD

If an automatic dishwasher is not available or not of sufﬁ cient size to accommodate the cell, a large container capable of holding the electronic cell can be used.

1. Mix an automatic dishwasher detergent with hot water in a ratio of 4 oz. of detergent

to one gallon of water. Water temperature should be between 150° F and 170° F. Be careful to avoid prolonging skin contact with solution and DO NOT splash solution in the eyes.

2. Soak the cell in the solution for about 15 minutes. The solution should be agitated in

some way every 2 to 3 minutes by sloshing or stirring the solution.

3. Remove the cell from the cleaning solution and place in a clean container of hot water

(150° F to 170° F) for rinsing and let set for 10 minutes.

4. Remove the cell from the rinse water and allow to drain and dry before using.

5. If there is any detergent residue remaining, rinse again, since it may affect the efﬁ ciency

of the air cleaner.

NOTE: The ionizer wires may become so dirty that an occasional cleaning is

recommended. With a damp cotton ball, wipe the ionizer wires by placing the wire between ﬁ nger and thumb.

Discoloration

of the Cell

Replacing the

Cell in Cabinet

Occasionally, after the cleaning process, the cell may seem stained. If the stain is black or very dark, it is probably detergent residue and should be rinsed off at once. If yellowing appears, it is probably stain from tobacco or other smoke. The yellowing does not affect air cleaner efﬁ ciency. Use an ammonia-based detergent to clean tobacco tar and other smoke residue from the collector plates.

After the cell has been washed, check for broken ionizer wires and bent collector plates. If broken wires are observed, return unit to Authorized Warranty Station for wire replacement. If bent collector plates are observed, carefully straighten with a screwdriver or other ﬂ at object. BE CERTAIN THAT NO TWO COLLECTOR PLATES ARE TOUCHING AS THIS WILL CAUSE AN ARC AND PREVENT THE AIR CLEANER FROM OPERATING PROPERLY. The operation light will not light and the electronic cell will not function.

Remember that the electronic air cleaner has a cell key which prevents the cell from being pos ition ed inc or rectl y. If the cell s eems s tuck when b eing i nser te d or th e acces s cove r wil l not ﬁ t securely, check to be sure that the cell is being positioned properly. If excessive force is used, the cell or air cleaner unit could be damaged. Airﬂ ow arrows point toward fan motor.

If the cell is placed into the air cleaner while still damp, the indicator light may not come on until the cell is dry, which would normally take about two hours. If the cell is energized and annoying snapping sounds occur, the cell should be removed from the air cleaner and allowed to thoroughly dry.

Troubleshooting

Guide

The activated carbon ﬁ lter must be replaced when it is no longer effective in eliminating odors. The life of the carbon ﬁ lter will depend on the concentration of odors and fumes in the air passing through the air cleaner. Under normal operating conditions, the carbon ﬁ lter should last from three to six months. The carbon ﬁ lter must be in place for the air cleaner to operate.

If you experience problems with the operation of your air cleaner, please:

• Make sure electronic cell is clean, dry, and properly installed.

• Make sure pre-ﬁ lter and carbon ﬁ lter are both properly installed.

• Make sure the top cover is properly snapped in place.

• Check fan motor and indicator lamp on all speed settings starting with low.

If your air cleaner still has any of the following problems, proceed step by step as shown

below until no further action needs to be taken.

PROBLEM 1 - Fan Off, Lamp Off

• Make sure the supply cord is plugged into a standard household receptacle.

• Make sure there is voltage to the receptacle by using any other electric device.

• Make sure the carbon ﬁ lter is in place.

• Make sure the top access cover is properly in place in order to actuate the interlock switch. The interlock switch is provided for consumer safety and should never be bypassed.

• No further corrective actions should be taken by the consumer. Return unit to Regional Authorized Warranty Station for repair (see page 10.)

PROBLEM 2 - Fan On, Lamp Off

• Allow the electronic cell to dry completely before reinstalling it into the unit.

• Unplug the unit and check electronic cell to see if any of the collector plates are touching. Gently straighten and evenly space the plates.

• Check electronic cell to see if any of the ionizer wires are broken. See page 8 for location. If broken wires are observed, no further corrective actions should be taken by the consumer. Return unit to Regional C-90A Authorized Warranty Station for repair.

PROBLEM 3 - Fan Off, Lamp On

• This condition represents an unserviceable failure of the air cleaner. Return to Regional Authorized Warranty Station for repair.
