WARNING

• This product earned the ENERGY STAR® by meeting strict energy efficiency guidelines set by Natural Resources Canada and the US EPA. This product meets ENERGY STAR requirements only when used in Canada.
• To ensure quiet operation of the ENERGY STAR certified H/ERV, each product model must be installed using sound attenua-tion techniques appropriate for the installation.
• The way your heat/energy-recovery ventilator is installed can make a significant difference to the electrical energy you use. To minimize the electricity use of the heat/energy recovery ventilator, a stand-alone fully ducted installation is recommend-ed. If you choose a simplified installation that operates your furnace air handler for room-to-room ventilation, an electrically efficient furnace that has an electronically commutated (EC) variable speed blower motor will minimize your electrical ener-gy consumption and operating cost.
• Installation of a user-accessible control with your product model will improve comfort and may significantly reduce the prod-uct model’s energy use.

For residential use only

• Before installation careful consideration must be given to how this system will operate if connected to any other piece of mechanical equipment, i.e. a forced air furnace or air handler operating at a higher static pressure. After installation, the compatibility of the two pieces of equipment must be confirmed by measuring the airflow of the Energy Recovery Ventilator (ERV) using the balancing procedure found in this manual. It is always important to assess how the operation of any ERV may interact with vented combustion equipment (i.e. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.)
• Residential ERV ventilation systems are not suitable for pool or spa applications.
• Products are designed and manufactured to provide reliable performance, but they are not guaranteed to be 100% free of defects. Even reliable products will experience occasional failures, and this possibility should be recognized by the user. If these products are used in a life support ventilation system where failure could result in loss or injury, the user should provide adequate back-up ventilation, supplementary natural ventilation or failure alarm system, or acknowledge willingness to accept the risk of such loss or injury.
• Your ventilation system should be installed in accordance with the local building code that is in effect, in absence of such requirements, it is recommenced to check with local authorities having jurisdiction in your area prior to installing this product.

Installation examples

FULLY DEDICATED SYSTEM BEST FOR NEW CONSTRUCTION

Suggested installation for:

• Hydronic baseboard
• Infloor heating
• Electric baseboard
• Mini split heat pump

Benefits: Provides the best fresh air distribution in the house; lowest operation cost since the furnace/air handler unit is not needed.

Stale air is drawn from key areas of home (bathroom, kitchen, laundry)
Fresh air supplied to main living areas

1. Stale air is drawn from key areas of the home requiring local exhaust (bathroom, kitchen, laundry room).
2. Fresh air is distributed directly to habitable rooms in the house (bedrooms, living room)
3. The ERV’s airflow must be balanced after installation using the procedure found in the section “AIRFLOW BALANCING”

PARTIALLY DEDICATED SYSTEM (BETTER)

Suggested installation for:

• Central furnace (air handling unit or central air conditioners)
• When ducting fresh air to living area is not possible or practical, i.e. expensive or when the central AHU will operate year-round
• Recommended units: P 1.2E-D and P 1.2E-D-EC – to avoid drawing outdoor air directly into the furnace when the unit is not running

Benefits: Conditions the fresh air prior to distributing it throughout the house

1. Furnace blower must operate when ventilation from ERV is required. The furnace should be set to run continuously or interlocked with ERV. See furnace electrical connection on page 19.
2. Stale air is drawn from key areas of the home (bathroom, kitchen, laundry room).
3. Fresh air is supplied to the return air plenum of the furnace.
4. Due to the difference in pressure between the ERV and the equipment it is being connected to the ERV’s airflow must be balanced on site, using the procedure found in the section “AIRFLOW BALANCING”

• In the case of a multi-zone system, please contact Greentek customer service prior to installing any installation type requiring the use of the furnace interlock”

ERV/Furnace ducting for Partially Dedicated System

• For Greentek Energy Recovery Ventilators (ERV) that do not include an outdoor air motorized damper: If you are using a partially dedicated or simplified installation, i.e. connecting the ERV supply air duct to a furnace’s return air duct, the ERV must operate continuously. When the ERV is turned off, no warm exhaust air will flow through the ERV but the furnace’s fan will continue to draw in outdoor air directly into the furnace. If it’s cold outside, cold air will be introduced, without re-heating, directly into the furnace.
• If the ERV is installed such that the homeowner may turn off the ERV during the winter, we recommend installing a motorized damper between the ERV’s supply air and the furnace’s return air duct that closes when the ERV is not operating. To install a damper accessory to the product, locate the auxiliary connector on the side of the electrical box. See Figure 1. Using the included wire harness, connect the damper accessory to the product.

SIMPLIFIED INSTALLATION (GOOD) (RETURN/RETURN METHOD)

Suggested installation for:

• When bathroom and kitchen already have local exhaust system
• May be suitable for retrofitting
• Recommended units: P 1.2ED and P 1.2E-D-EC – to avoid drawing outdoor air directly into the furnace when the unit is not running

Benefits: Least expensive installation type

1. Furnace blower must operate when ventilation from ERV is required. The furnace should be set to run continuously or interlocked with ERV. See furnace electrical connection on page 19.
2. A minimum separation of 1m (3`3’’) is recommended between the two direct connections.
3. In order to prevent exhausting any fresh air, the ERV’s exhaust air connection should be upstream of the ERV’s supply air connection when ducting to the furnace’s cold air return.
4. Due to the difference in pressure between the ERV and the equipment it is being connected to the ERV’s airflow must be balanced on site, using the procedure found in the section “AIRFLOW BALANCING”

• In the case of a multi-zone system, please contact Greentek customer service prior to installing any installation type requiring the use of the furnace interlock”

ERV/Furnace ducting for Simplified Installation

• For Greentek Energy Recovery Ventilators (ERV) that do not include an outdoor air motorized damper: If you are using a partially dedicated or simplified installation, i.e. connecting the ERV supply air duct to a furnace’s return air duct, the ERV must operate continuously. When the ERV is turned off, no warm exhaust air will flow through the ERV but the furnace’s fan will continue to draw in outdoor air directly into the furnace. If it’s cold outside, cold air will be introduced, without re-heating, directly into the furnace.
• If the ERV is installed such that the homeowner may turn off the ERV during the winter, we recommend installing a motorized damper between the ERV’s supply air and the furnace’s return air duct that closes when the ERV is not operating. To install a damper accessory to the product, locate the auxiliary connector on the side of the electrical box. See Figure 1. Using the included wire harness, connect the damper accessory to the product.

EXTERIOR DUCTING INSTALLATION

WEATHERHOOD LOCATION

Decide where your intake and exhaust hoods will be located.

Locating the Intake Weatherhood

• Should be located upstream (if there are prevailing winds) from the exhaust outlet.
• At a minimum distance to 900 mm (3′) away from dryer vents and furnace exhaust (medium or high efficiency furnaces), driveways, oil fill pipes, gas meters, or garbage containers.
• At a minimum height of 460mm (18’’) above the ground, or above the level of expected snow accumulation.
• Ideally, keep weatherhoods 1m (3′) from corners.
• Do not locate in the garage, attic, crawl space, or underneath deck.

Locating the Exhaust Weatherhood

• At least 460mm (18″) above ground or above the depth of expected snow accumulation
• Ideally, keep weatherhoods 1m (3′) from corners.
• Not near a gas meter, electric meter or a walkway where fog or ice could create a hazard
• Do not locate in a garage, workshop or other unheated space

INSTALLING THE DUCTING TO THE WEATHERHOODS

• A well designed and installed ducting system will allow the ERV to operate at its maximum efficiency. The inner liner of the flexible insulated duct must be secured to the sleeve of the weatherhood (as close to the outside as possible) and to the appropriate duct connection on the ERV. The insulation should remain full and not crushed. The outer liner, which acts as a vapor barrier, must be completely sealed to the outer wall and the ERV using tape and/or caulking. A good bead of high quality caulking (preferably acoustical sealant) will seal the inner flexible duct to both the ERV duct connection and the weatherhood prior to securing them.
• To minimize airflow restriction, the flexible insulated duct that connects the two outside weatherhoods to the ERV should be stretched tightly and be as short as possible.
• Twisting or folding the duct will severely restrict airflow.
• See “Installation Diagram Examples” for installation examples.

STEPS FOR HOOD INSTALLATION:

1. Using the duct connection of the outside hood, outline the intake & exhaust holes to be cut. The holes should be slightly larger than the duct connection to allow for the thickness of the insulated flexible duct. Cut a hole for both the intake and exhaust hoods..

2. Pull the insulated flexible duct through the opening until it is well extended and straight. Slide the duct’s inner vinyl sleeve over the hood duct connection and secure. Pull the insulation over the duct and pull the vapor barrier over the sleeve. Secure with appropriate tape or sealant.

3. Push the hood into the opening and then attach the hood to the outside wall with mounting screws.
   Repeat the installation procedure for both the supply and exhaust hoods

4. Using a caulking gun, seal around both hoods to prevent any leaks.

Interior ducting installation

• To maximize airflow through the ductwork system, all ducts should be kept short and have as few bends or elbows as possible.
• 45º elbows are preferable to 90º.
• Use “Y“ ducts instead of “T” ducts whenever possible.
• All duct joints must be fastened with screws or duct sealant and wrapped with aluminum foil duct tape to prevent leakage.
• Galvanized ducting from the ERV to the living areas in the house is recommended whenever possible, although flexible ducting can be used in moderation when necessary.
• To avoid possible noise transfer through the ductwork system, a short length (approximately 300 mm, 12’’) of nonmetallic flexible insulated duct should be connected between the ERV and the supply/exhaust ductwork system.
• The main supply and return line to/from the ERV must have the same diameter as the duct connection or larger.
• Branch lines to the individual rooms may be as small as 100 mm (4’’).

Installing ducting to ERV

• For flexible duct installation, slide flexible ducting onto duct connection. Then install a cable tie over flexible duct to prevent leakage between the ducting and the duct connection.
• In the case of solid ducting, slide duct over duct connection, screw in place and seal.

Supply air grilles location
In homes without a forced air furnace, fresh air should be supplied to all habitable rooms, including bedrooms and living areas. It should be supplied from high wall or ceiling locations. Grilles that diffuse the air comfortably are recommended. In homes with a forced air furnace, you may want to connect the ERV to the furnace ductwork (see information below).

Exhaust air grilles location
The stale air exhaust system is used to draw air from the points in the house where the worst air quality problems occur. It is recommended that return air ducts be installed in the bathroom, kitchen, and laundry room. Additional return air ducts from strategic locations may be installed. The furnace return duct may also be used to exhaust from. In this method, the exhaust air is not ducted back from bathrooms, kitchens, etc to the ERV with “dedicated lines”.

ERV installation

• Have a nearby power supply (120 volts, 60Hz)
• Choose a location which allows the possibility of mounting the unit to supporting beams.
• To minimize noise, do not install unit in living area

LOCATION

• The ERV must be located in a conditioned space where it will be possible to conveniently service the unit. Typically the ERV would be located in the mechanical room or an area close to the outside wall where the weatherhoods will be mounted. If a basement area is not convenient or does not exist, a utility room may be used.
• Attic installation must meet the following conditions:
  • Attic temperature must be above freezing conditions at all times and for best performance should be 12°C (54 °F).
  • The condensate drain (if included) must be installed so that the condensate drains and is protected from freezing.
  • The attic is easily accessible for equipment maintenance and inspection.
• Connecting appliances to the ERV is not recommended. These include:
  • Clothes dryer
  • Range top
  • Stovetop fan
  • Central vacuum system
  • Bathroom exhaust fans unless they are specifically designed for this purpose
    These appliances may cause lint, dust or grease to collect in the ERV, damaging the unit.
    Connecting any of these types of appliances to the ERV will void your warranty.
    The unit should be installed in the wall mounted position in regions where the outdoor temperature is 13°F (-25°C) or less for 48 consecutive hours or more while the indoor relative humidity is at 40% or more.

Mounting

CEILING INSTALLATION

1. Using the screw with washer mount the mounting bracket through the rubber insulator. Ensure the bracket is straight.
2. Using the screw with washer mount the brackets at the bottom of the unit.
3. Slide the unit the bracket as shown above.
4. Secure both side of the unit using the same method as step 1.
   We recommend placing the duct on the unit at this stage of the unit’s installation.

WALL INSTALLATION

1. Using the screw with washer mount the mounting bracket through the rubber insulator. Ensure the bracket is straight.
2. Using the screw with washer mount the brackets at the bottom of the unit.
3. Slide the unit in the bracket and secure with setting screw.

Airflow balancing

Balancing must be completed using the Greentek Programmable Touch Screen Wall Control

ENTERING BALANCING MODE
In the options menu during the initial 5 second countdown sequence, long press on “ECO” area for 5 seconds to enter basic balancing mode. The supply and exhaust fans are adjusted on high speed only and the offsets are proportionally applied to the medium and low speed automatically.

• STAGE 1 (ADJUST LEVEL OF EXHAUST FAN IN HIGH SPEED):

  • In this step, balance exhaust fan and measure airflow on the exhaust air side
  • Pressing on “up” or “down” will adjust the fan speed in increments of 1%.
  • Once the desired exhaust airflow is reached, press on “next” and move on to the next stage.

• STAGE 2 (BALANCE SUPPLY FAN ONLY IN HIGH SPEED):

  • In this step, balance supply fan and measure airflow on the supply air side
  • Pressing on “up” or “down” will adjust the fan speed in increments of 1%.
  • Once happy with the outcome, press on “next” to complete balancing
  • The supply and exhaust offset values will be proportionally applied to low and medium speed as well.

WALL CONTROLS

• Please see instruction manuals for individual controls for proper wiring and set up of control systems.

  1. Ensure that unit is not plugged when connecting the control
  2. Recirculation mode is only available with the Flex100H ES, HERO series and the models with the “R” suffix at the end of the model number.
     The wiring connectors can be removed for easier connection.

CENTRAL CONTROLS
