Introduction
Your RS4 Whole House IAQ System is a high efficiency air cleaning system designed to remove
all three types of airborne contaminants: particles, biologicals, and gas phase contaminants. The
large surface areas of the air cleaner and activated carbon help to reduce air velocity and static
pressure resistance for more effective filtration.
Section I. Cabinet Installation
1) Turn the thermostat fan switch to the “OFF” position.
2) Turn off power to the furnace/air handler.
3) Remove the existing filter from the furnace/air handler or return air grille.
4) Locate the RS4 cabinet on the return side of the ductwork, adjacent to and upstream of the
blower compartment. This placement will ensure that the furnace blower and cooling coil are
kept clean. Determine the mounting orientation in a location that is readily accessible for
service and maintenance, allowing a minimum of 27” in front of the slide-out access panel.
5) If the cabinet is installed on a flat surface, seat the cabinet on vibration pads (1/2” minimum) to
provide adequate clearance for the door operation.
6) When securing the RS4 cabinet into the HVAC system, do so with the cabinet door in place to
keep the cabinet plumb. This will ensure that the access door fits properly after installation.
7) The RS4 cabinet uses interchangeable block-off plates that can be positioned to allow airflow
through the cabinet at a right-angle or flow-through from side to side or top to bottom.
Mounting holes are provided in the air cleaner cabinet for #10 sheet metal screws or 1/8”
rivets. All system components allow for installation with airflow in any direction.
8) The RS4 cabinet includes one set of adjustable duct flanges that can adjusted to connect the
top/bottom 24”x8” duct opening to duct sizes of 24’x8”, 24”x9”, 24”x10”, 24”x11”, or 24”x12”.
The cabinet is shipped with top flanges in the 24”x10” center position. To adjust the flanges,
remove the flange screws, adjust the flanges to the desired duct size, and secure with screws.
Openings on the side of the cabinet measure 23.5” x 13.5”. Additional duct flange kits for side
connections (part no. RS4-FLANGEKIT) are available as an optional accessory.
