SPECIFICATIONS

IMPORTANT

The specifications in this publication do not include normal manufacturing tolerances; therefore, an individual unit may not exactly match the listed specifications. This product is tested and calibrated under closely controlled conditions, and some minor differences in performance can be expected if those conditions are changed.

Model:

F35F Expandapac Media Air Cleaner includes cabinet, access door, Expandapac media filter, filter frame, and combs.

Application:

Use with gas, oil, and electric forced warm air furnaces and with compressor cooling. Can be used with heat pumps if filter is changed regularly to prevent excessive pressure drop.

Arrestance Efficiency:

Efficiency ratings are based on National Bureau of Standards Dust Spot Method using atmospheric dust and American Society of Heating, Refrigerating and Air-Conditioning Engineers Standard 52.1-92.

—Initial Atmospheric Dust Spot Efficiency: 25.8% —Average Atmospheric Dust Spot Efficiency: 32.0% —Average Synthetic Dust Weight Arrestance: 92.0% —ASHRAE Dust Holding Capacity: 55g The above data is for a 16 x 25 in. filter.

Filter Media:

Expandapac.

F35F Expandapac™ MEDIA AIR CLEANER

M939A

Mounting:

Mounts in any position in the return air duct next to the furnace blower compartment. Airflow must be in the direction of the arrow on the filter. Cabinet is sturdy enough to support weight of a residential furnace and evaporator coil.

Underwriters Laboratories, Inc.:

UL 900, Class 2 listed.

Upgrade Path:

The F35 uses the same cabinet as the F50 Electronic Air Cleaner. Upgrade requires installing the cell key, electronic cells, protective screens, and power box installation and wiring.

Accessory:

S830A Clogged Filter Indicator.

Replacement Parts:

Replace Expandapac media filter annually or more often if reduced airflow results in lower heating/cooling equipment performance. See Replacement Parts section for Media Filter and Frame/Comb replacement part numbers.

PLANNING THE INSTALLATION

Location

Install the media air cleaner where all the air passing through the system is circulated through it. The best location is in the return air duct next to the blower compartment so the media air filter can help to keep the blower motor and evaporator coils clean. Do not mount in the supply air duct.

Applications with a Humidifier

The media air filter is compatible with humidifiers. Avoid applications where water mist can reach the media. If an atomizing humidifier is used, the filter media will require replacement more often because of minerals in the water.

Choose Mounting Position

The media air cleaner can be mounted in any position, but the arrow on the cartridge must point in the same direction as the airflow. See Fig. 3-10 for proper location of the media air cleaner for a variety of furnace installations. Note that the media air filter cabinet is sturdy enough to easily support the weight of the furnace and evaporator coil. See Fig. 4.

For most efficient air cleaning, spread airflow evenly across the face of the media. If the duct is a different size than the media air cleaner cabinet, gradual transitions are required. If the duct turns sharply just before the air filter, turning vanes are required (Fig.12).

Choose a location that is readily accessible for checking and replacing the filter. Allow at least 26 in. (660 mm) clearance in front of the unit for removal of the filter.

Install the media air cleaner where the temperature will not exceed the ratings in the Specifications section.

Applications with Air Conditioning

Mount the media air filter upstream of the evaporator coil in a cooling system. The filter will help to keep the coil clean and reduce maintenance.

Applications with a Charcoal Filter

Add an activated charcoal filter to the air handling system to remove gaseous (nonparticulate) contaminants from the circulated air. A common residential application is to remove odors that cannot be removed by mechanical air filters. The activated charcoal filter, if used, should be installed downstream from the media air cleaner to protect the charcoal filter from lint and other particles.
