PLANNING THE INSTALLATION

Application

The F50E is used in a forced air heating, cooling, or ventilating system. It operates when the system blower is on. Models with internal solid state air flow switch require only line voltage connection. Models without the air flow switch can be energized through the fan switch, a dpdt fan relay or an air flow switch such as the S688 Sail Switch. Unless the F50E with solid state air flow switch is used, an isolating fan relay or air flow switch is required if the system has a multispeed or modulating blower motor.

Review Installation Requirements

The air cleaner should be installed where all the air passing through the system circulates through it. The best location is in the return air duct next to the blower compartment so the air cleaner can help keep the blower motor and evaporator coils clean. Do not mount in the discharge air duct.

For most efficient air cleaning, airflow must be spread evenly across the face of the air cleaner. If the duct is a different size than the air cleaner cabinet, gradual transitions are recommended. If the duct turns sharply just before the air cleaner, turning vanes are recommended.

M4697

Applications with Air Conditioning

The air cleaner should be installed upstream of the evaporator coil. The air cleaner helps keep the coil clean, reducing maintenance. Also, if the air cleaner is downstream, the high relative humidity of the cooled air leaving the evaporator coil can cause water condensation on the cells, reducing air cleaner efficiency.

Applications with a Humidifier

An evaporative humidifier can be mounted upstream of the air cleaner. An atomizing humidifier should be mounted downstream of the air cleaner, even though hard water salts will be blown into the living space and deposited as dust. If an atomizing humidifier must be mounted upstream of the air cleaner:

1. Mount it as far as possible upstream of the air cleaner.

2. Install a standard disposable furnace filter between the

humidifier and the air cleaner to trap water droplets and hard water salts.

3. Clean the air cleaner frequently to prevent a hard water

salt buildup.

4. Note that the volume of water that passes through an

atomizing humidifier can overload the air cleaner, resulting in hard water salts being deposited as dust in the living space.

68-0072—5

Applications with an Activated Carbon Filter

If desired, an activated carbon (charcoal) filter can be used to remove odors or other gaseous contaminants (not particlebased), which are not removed by the air cleaner. Locate the carbon filter:

•Downstream from the air cleaner. This means, of course, that dust from the carbon filter will not be collected by the air cleaner and will be deposited in the living space.

• Outside the air cleaner cabinet. Some carbon filters are combustible, and contact with high voltage could result in smoke or fire.

• Where carbon granules cannot fall into the electronic cell(s). Use a disposable furnace filter if necessary between the carbon filter and the electronic cell(s).

• With proper transitions, if the activated carbon filter requires a different size duct than the air cleaner. Allow 20 degrees expansion per side, per fitting.

Applications with Outdoor Air Intake

Return air temperature must be at least 40°F (4°C). Lower temperatures can cause ionizer wire failure. If outdoor air is used, warm it ahead of the air cleaner by:

• Making sure the outdoor intake is far enough ahead of the air cleaner so the return and outdoor air is thoroughly mixed. Stratified air can dump a stream of very cold air into one section of the air cleaner.

• Adding baffles ahead of the air cleaner to force thorough air mixing.

• Installing a preheater, if large amounts of outdoor air are used. The preheater, which could be an electric strip heater or hot water coil, should be controlled by a thermostat. Hot water or steam coils should be protected by a freeze-up control.

Choose Location

Choose a location that is readily accessible for regular inspection and cleaning. Allow at least 13 in. (330 mm) in front of the access door for removing the prefilters and electronic cells. Allow enough room above the power supply so the power supply can be serviced without removing pipes, ducts, or other heating system components.

WARNING

Heavy Equipment. Can cause injury or equipment damage.

If the access door faces down, the latch may not hold, and the cells and prefilters can fall unexpectedly. Also, nothing holds the cells and prefilters in place once the access door is opened.

The air cleaner can be mounted in any position except with the access door facing down. Figs. 3-10 show proper air cleaner mounting with a variety of furnace installations.

Determine Sheetmetal Requirements

The air cleaner is adaptable to all new or existing residential forced air heating, cooling and ventilating systems. Sheetmetal transitions, turning vanes, or offsets may be needed in some applications.

Transitions

Tr ansitions are needed when the duct is a different size than the air cleaner cabinet. Gradual transitions reduce air turbulence and increase efficiency. Limit expansion to 20 degrees (about 4 in. per running foot [100 mm per 300 linear mm]) on each side of a transition fitting. See Fig. 11.

(2-cell model shown).

Clean Blower Compartment

❑ Remove and discard the existing furnace filter. ❑ Thoroughly clean the blower compartment. ❑ If possible, power vacuum ductwork to remove accumulated

dust in existing home, or construction dirt in a new home. The electronic air cleaner cannot remove dust that has settled in the blower compartment and distribution ducts.

❑ Check the edges of the furnace fan blades for dirt buildup

and clean as necessary. The fan will not deliver the rated cfm if the blades are dirty.

Review the Installation Plan

❑ Temporarily place the cabinet on the floor; position as it will

be when installed.

❑ Remove and set aside the access door, electronic cells

and prefilters, checking that the selected location provides enough clearance for easy removal and replacement of these components. Unless the power supply will be remotely mounted, make sure there is room above the unit to wire and service the power supply, including the optional W8600E.

❑ Make sure that shop-fabricated sheetmetal components,

such as turning vanes, are on hand.

Remote Mount Power Supply, if Desired

❑

If remote mount is not desired, go on to Fasten the Cabinet to the Furnace section.
