Visually check the installation. Make sure:
• Airflow is in the direction of the arrow on the
Expandapac media air filter.
• Turning vanes and transitions, if used, are properly
installed.
• Joints in sheet metal between media air cleaner and
furnace are sealed.
• All sheet metal connections are complete.
• Original furnace filter was removed and blower
compartment was cleaned.
Replace any access doors removed during the Installation or
Checkout.
Run the furnace or cooling system through one complete
cycle to make sure the system operates as desired.
Maintenance
Replace the media filter when pressure drop across the
media filter reaches 0.5 in. wc (0.1 kPa) or at least annually. If
the media air filter is installed downstream from an atomizing
humidifier or if the installation includes both heating and
cooling, more frequent replacement may be necessary.
Clogged media filter must be replaced promptly to avoid
restricting airflow and reducing efficiency of the heating-
cooling system. Record the replacement date in the space
provided on the replacement media filter.
Replace the Expandapac Media Filter as follows:
1. Remove the cabinet door and pull out the dirty filter
assembly.
2. Remove all the combs and two frame panels. Set them
aside. Dispose of the dirty filter.
3. Open the new media filter; expand it and set it upright
on a flat surface.
4. Insert one end panel tab into the retainers on the frame.
Fold in the end panel flanges and push the tab
completely in, making sure the end panel flanges are
inside the frame flanges. See Fig. 15.
5. Repeat step 4 on the opposite corner.
6. Flip over the assembly and repeat steps 4 and 5 on the
remaining two corners.
7. Lay the filter assembly down flat so the arrows point up.
Insert the combs as shown in Fig.16, aligning them with
the notches in the end panel flanges. Make sure the
combs are inserted completely.
8. Insert the new filter assembly into the cabinet and close
the door.
See Replacement Parts in the Specifications section. If desired,
install the S830A Clogged Filter Indicator to allow visual
indication of when the media needs replacing. Install and adjust
the S830A by following the instructions provided with the unit.
