INTRODUCTION

These instructions cover the installation, operation and maintenance of an EZXCABCR High-Efficiency Air Filtration System. See Fig. 1. Refer to Fig. 2 for a list of major components.

DESCRIPTION AND USAGE

APPLICATION
This High Efficiency Air Filtration System must be used in a forced air heating, cooling or ventilation system. This High-Efficiency Air Filtration System cleaner should be installed in the system so that all the system air is circulated through this air cleaner. The High Efficiency Air Filtration System cleaner will only remove the airborne contaminants delivered to it. Maximum performance is obtained when the system blower is set for continuous operation.

INSTALLATION REQUIREMENTS
The best location for the High Efficiency Air Filtration System cleaner is in the return air duct next to the blower compartment. In this location, the blower motor and cooling coils will be kept clean. Do not install the air cleaner in the discharge (supply) air duct. Before installing this High Efficiency Air Filtration System cleaner, consider the application. If a transition is required, refer to Fig. 3 or Fig. 4. The unit must be readily accessible for periodic inspection and replacement of the EZ-Flex™ filter to maintain maximum efficiency and trouble-free operation.

SELECT THE LOCATION FOR THE AIR CLEANER

Select a location that is readily accessible for periodic inspection and cleaning. Allow a minimum of 26-in. (660mm) in front of the access panel for EZ-Flex filter removal and replacement. For complete unit, dimensions refer to Fig. 5.
DIRECTION OF AIR FLOW THROUGH THIS AIR CLEANER

The High Efficiency Air cleaner is set up for left-to-right airflow, when facing the access door. For the right to left air flow remove the EZ-Flex filter, turn it around and replace in the cabinet. The directional arrows on the filter must point in the direction of airflow.

AIR CONDITIONING

The High Efficiency Air cleaner should be installed upstream of the cooling coil. This will help keep the coil clean and reduce air conditioning coil maintenance. Improved cooling efficiency is the result, which directly affects energy costs. A clean coil will reduce utility costs.
IMPORTANT: Failure to replace EZ-Flex filter can cause damage to the cooling system.

TURNING VANES

If the air cleaner is installed adjacent to a 90° duct connection, add turning vanes inside the duct to improve the air distribution across the face of the high efficiency air cleaner. See Fig. 6.

HUMIDIFIERS

Location of the system humidifier is important to the operation of the air cleaner. When an evaporator type humidifier is used, it may be installed between the furnace warm air duct and the return air duct without affecting the air cleaner.

INSTALLATION

WARNING

CARBON MONOXIDE HAZARD
Failure to follow this warning could result in personal injury or death. Do not remove door during blower operation or operate blower with door removed or improperly latched.

CAUTION

CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and wear appropriate protective clothing and gloves when handling parts.

1. Turn off power disconnect and install lockout tag.

2. Check the rating given on this product to make sure it is suitable for your application.

3. Remove the old furnace filter and discard it.
   NOTE: The air cleaner cannot remove existing dirt from the blower and ducts.
   NOTE: The following is a typical installation of this air cleaner on an upflow furnace. You may have to alter the installation to fit your specific application.

4. Locate the cabinet in the cold air return duct so that all of the return air flows through the unit. If the furnace and air cleaner openings are different, use a transition. See Fig. 3.

5. Mounting holes are provided for simple connection to ductwork and unit cabinet. See Fig. 7. The 0.14 in. holes are sized for #8 sheet metal screws, or 1/8 in. rivets. If the adjoining ductwork is flanged, install the screws so that the screw heads are inside the cabinet. This will prevent damage to the EZ-Flex filter during removal and installation.

6. After the cabinet has been secured, use caulk or tape to seal seams airtight.

7. Remove Filter from box, assemble then place in cabinet. See Fig. 8.

8. Install access door and ensure a tight seal.

MAINTENANCE

HOW TO MAINTAIN YOUR AIR CLEANER

The filter media in your cabinet MUST be replaced periodically. Filters of this type should be replaced, on average, every 6 months but can vary based on the environmental conditions in the home.

STEPS FOR REPLACING FILTER

1. Turn off the power to the blower.
2. Open the access door by pulling the handle and lifting upward. Remove the door completely.
3. Pull the used filter straight out of the cabinet and disassemble and discard media only.
4. Remove the new filter from the box and assemble it. See Fig. 8.
5. Slide the newly assembled filter into the cabinet with Air-Flow arrow pointing in the direction of airflow.
6. Replace the access door.
