HERO HS300 Whole House Filtration Unit

Introduction

You have purchased a very effective air cleaning and treatment system incorporating HEPA (High Efficiency Particulate Arrestance) filter technology. This is the type of air cleaning equipment that respiratory specialists recommend most.

To optimize the performance of your HEPA Filtration System, it should be installed by a professional contractor who is familiar with your indoor air quality situation and the operation of other heating, ventilation and air conditioning equipment that you may have.

Planning Installation

For integrated system installation

• Verify clearance on the ductwork to mount the unit using the Forced Air heating/cooling system.
• Minimum clearance requirements for maintenance and service.
• Electrical power requirements.
• Interaction between the HEPA filter unit and other mechanical devices.

The Whole House HEPA unit is a versatile appliance with multiple installation configurations. It is recommended to take your time in planning the installation. Several installations are illustrated for Whole House filtration applications:

• Return to return integrated with the forced air heating/cooling system.
• Central draw points using dedicated duct system.
• Consult the manufacturer for other special applications.

Types of Installation

I. RETURN TO RETURN INTEGRATED SYSTEM

DUCTING FLAIR SYSTEM

Installation: The Whole House HEPA Filtration system is designed to install directly onto the return air plenum of the forced air heating/cooling system. Choosing this type of installation eliminates the need to externally duct the HEPA filter unit to the plenum system. If you choose this type of installation, it is recommended that you run the fan on your forced air system continuously to maximize its cleaning ability.

Diagram: Illustration shows the 'Ducting Flair System' where the unit is mounted on the return air plenum.

COLLAR MOUNT SYSTEM

Installation: The Whole House HEPA Filtration system can be converted to use 8-inch round collars for applications requiring ducting. The kit includes two 8-inch round collars, two mounting brackets for wall or floor mounting, an installation guide, and fasteners.

Diagram: Illustration shows the 'Optional Collar System' where the unit is mounted on a wall.

Tips to Installer: The Whole House HEPA Filtration system does not replace the filter from the forced air heating/cooling system. Regular maintenance of this filter is necessary to permit the good operation of the forced air heating/cooling system.

Installation Note: Installation should be performed by a certified professional. Consult your HVAC product manufacturer if the usage of this product will affect the performance of your forced air heating/cooling system.

II. STAND ALONE SYSTEM

ATTIC INSTALLATION

Ideal for homes without a forced air heating/cooling system. Allows for air filtration and circulation throughout the home. The HEPA system must be operated continuously whenever a part or all of the system is located in an unconditioned space to avoid condensation in the ductwork below freezing (0°C, 32°F).

BASEMENT INSTALLATION

Ducting will usually consist of one return with grille from one side of the home, and one supply with grille at the opposite end of the home.

Installation Step-by-Step

Tools Required

• Phillips #2 or Robertson #1 screwdriver
• 3/32" drill bit
• Tin snips or metal shear
• Power Drill

Location

Return side connections are to be installed after the last branch on the return air plenum and minimum 2 linear ft distance from furnace.

A 5-ft power cord is supplied with the unit. If not available, a 120VAC outlet needs to be supplied.

Note to Installer

Refer to the general operation information section for details on how to remove the unit's door and filters.

Tips to Installer

Please consult local authorities to find out whether the installation of electrical products requires the services of a certified technician or electrician. Removing the filters from the unit will facilitate your job.

Ducting Flairs Mounting System

The Whole-House HEPA Plenum Systems are designed for single person installation. Once the holes are made in the main return duct and the unit is aligned, the installer just has to unfold the "Ducting Flairs" and screw the unit in place.

Step-by-Step Installation

Step 1: Preparing Return Air Plenum

Find a location that satisfies both service and maintenance requirements and proceed to cut holes as illustrated below.

Diagram: A template is taped to the return air plenum. The opening is cut with metal shears, pre-drilled for securing screws, and the template is removed. The diagram shows the required hole placement and dimensions (16" x 3.5").

Step 2: Preparing Ducting Flairs

Remove the door and filters and proceed to cut the insulation as illustrated below.

Cut the insulation along the inside edge of both inlet and outlet ports to remove the insulation from the port openings. A single cut allows for clean removal of the insulation piece. The unit should look like this when the foam piece is removed.

Cut the four metal tabs to release the mounting flairs for the inlet and outlet ports. Apply plenum seal tape all around both openings on the back of the unit. Bend tabs outward approximately 90 degrees.

Step 3: Mount HEPA

Align unit into place. Unfold the ducting flairs completely to sandwich the return air plenum between the ducting flair and the filtration unit. Install unit as usual using all supplied fastening hardware.

Step 4: Finishing

Remove protective plastic covers from all filters and replace them in their proper location (Stage 1, 2, and 3). Replace door and insert power cord into the receptacle of the filter units and the other end into the wall outlet.

Diagram: An illustration shows the unit with filters installed and the power cord connected.

General Operating Information

Door Switch

The unit has an access door at the front for filters and the speed selection switch. Opening the latch on the right side allows the door to swing open. A safety door interlock switch cuts power to the motors for safety. The door can be removed by holding the top and gently tapping the bottom edge.

Mode Selector

• II (280 CFM)
• I (208 CFM)

Operations

Maximum Filtration: 280 cfm

Normal Filtration: 208 cfm

Function

The Whole House HEPA system is comprised of a ventilator, speed selection switch, and 3 stages of filtration. The ventilator draws air through a pre-filter, an impregnated carbon pad for odor control, and finally the HEPA filter, which removes 99.97% of particles 0.3µm in size.

Mode of Function

The unit features two speeds: 208 CFM (low) and 280 CFM (high). It is recommended to operate the unit at the highest speed at all times to maximize the benefits of the HEPA filtration system. The low speed can be used if filtration needs are less critical.

Recommended Operation

For return plenum mount models, operate in conjunction with your forced air heating/cooling system. The system circulates air continuously, and the HEPA filter cleans a portion of it on each pass. It is recommended that the furnace blower be in operation whenever the filtration system is running. For stand-alone attic installations, operate continuously, especially in unconditioned spaces, to prevent condensation in ductwork below freezing temperatures (32°F, 0°C).

General Maintenance Information

When Should I Service My Unit?
