Installation Methods The Three Methods of Installation Installing the Ducting Between the ERV and Living Areas in the House The three methods of installation for the ERV system are: • The Simplified installation. A well designed and installed ducting system will allow the ERV to operate at its maximum efficiency. • The Partially Dedicated Installation All ducts should be kept short and have as few bends or elbows as possible to maximize airflow. Forty-five degree elbows are preferred to 90° elbows.
Simplified Installation Diagrams (150ERV and 200ERV) Simplified Installation (Return/Return Method) Key Points • The ERV must be balanced. • It is mandatory that the furnace blower run continuously or ERV operation be interlocked with the furnace blower. • The duct configuration may change depending on the ERV model. See specifications for your unit. • Check local codes / authority having jurisdiction for acceptance.
Partially Dedicated Installation Diagrams (150ERV and 200ERV) Partially Dedicated System This installation enables stale air to be drawn from the poorest air quality areas of the home (bathrooms, kitchen). Key Points • The ERV must be balanced. • It is recommended that the furnace blower run continuously or ERV operation be interlocked with the furnace blower to evenly distribute the fresh air throughout the house. • The duct configuration may change depending on the ERV model.
Fully Dedicated Installation Diagrams (150ERV and 200ERV) Fully Dedicated System This is a stand alone ERV system which is not connected to a force air system. Stale air is drawn from key areas of the home (bathroom, kitchen) while fresh air is supplied to main living areas Key Points • The ERV must be balanced. • The duct configuration may change depending on the ERV model. See specifications for your unit. • Check local codes / authority having jurisdiction for acceptance.
Simplified Installation Diagrams (120ERV) Key Points Sizing the Ductwork • The ERV must be balanced. • It is mandatory that the furnace blower run continuosly or ERV operation be interlocked with the furnace blower. • The duct configuration may change depending on the ERV model. See specifications for your unit. • Check local codes / authority having jurisdiction for acceptance.
Partially Dedicated Installation Diagrams (120ERV) Key Points Sizing the Ductwork • The ERV must be balanced. • It is mandatory that the furnace blower run continuosly or ERV operation be interlocked with the furnace blower. • The duct configuration may change depending on the ERV model. See specifications for your unit. • Check local codes / authority having jurisdiction for acceptance.
Fully Dedicated Installation Diagrams (120ERV) Fully Dedicated System for ERV • Stale air drawn from key areas of home (bathroom, kitchen, laundry) • Fresh air supplied to main living areas of home WARNING ERV must be balanced. Outdoors Exhaust Air to Outside STALE AIR from various parts of home. Field-supplied Balancing Damper (optional) i.e. bathrooms (if required), kitchens (if required). Fresh Air from Outside *Unit is normally balanced on HIGH speed with air handler blower ON.
Installation Requirements (ERV) WARNING 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. After installation, the compatibility of the two pieces of equipment must be confirmed, by measuring the air flows of the ERV, by using the balancing procedure found in this manual.
Suspend the Unit with the Adjustable Hanging Straps (150ERV and 200ERV) Use 4 screws and 4 washers (not incldued) to attach the hanging straps to the floor joists. The washer must be wider than the eyelet of the grommet on the hanging strap. By design, the adjustable hanging straps reduce the possibility of noise, resonance and harmonics. STEP 3. Hook the bottom grommets of the straps through the "S" hooks. Pull down vertically on the hand loops while lifting up the bottom of the cabinet.
Weatherhood Installation (ERV) Lifebreath Weatherhoods Available Parts 5” (125 mm) Part No. 99-185 6” (150 mm) Part No. 99-186 7” (200 mm) Part No. 99-187 Fixed, covered weatherhoods include a 1/4” (6mm) screen to prevent foreign objects from entering the duct work. Hoods are labelled Supply and Exhaust. The kit also includes 2 sleeve of pipe and 2 collars. WEATHERHOOD INSTALLATION Weatherhood Clearances OUTSIDE CORNER 36" (1m) recommended min.
Grilles The Lifebreath Techgrille Adjustable grilles should be used to balance the flow rates into and out of various rooms. The grilles should not be adjusted after balancing the unit. Grilles or diffusers should be positioned high on the wall or in the ceiling. Kitchen Exhaust grilles must never be connected to the range hood. They should be installed at least 4 feet (1.2 m) horizontally away from the stove.
Grille Fittings Rough-in Metal Fitting (Part # 99-RIMF 4/5/6/8/) Stack Head Elbow (Part # 99-WF4/ 99-WF6) Use this rough-in fitting before the drywall is installed. • Nail or screw the fitting onto the floor joist. • Available sizes are 4”, 5”, 6”, and 8” sizes. Use this rough-in fitting before the drywall is installed. This fitting is ideal for running ducting through 2” x 4” (min.) studded walls. • Nail fitting to stud. • Available sizes are 4” and 6” sizes. Nail Stack Head Elbow onto stud.
Installation of the Main Control The Lifestyle Controls may be installed onto a flush mounted 2" x 4" electrical switch box or it may be surface mounted onto a wall. Only 1 master control should be installed to a ventilation system (the Face Plate on this illustration may not be exactly the same as yours). 1. Remove the Operating Instructions Card from the top of the Control (Figure A). 2. Separate the Face Plate from the Back Plate by firmly pulling apart (Figure B).
Installation and Operation of 20 Minute and 20/40/60 Minute Timers Operating your Lifestyle 20 Minute or 20/40/60 Minute Timers Press and release the Select Button to activate high speed override. The High Speed Status Light illuminates and the unit runs on high speed ventilation for 20 minutes. High Speed Status Lights The Lifestyle 20/40/60 Minute timers provide an extended override time of 20 - 40 additional minutes by pressing and releasing the Select button.
Interlocking the ERV to an Air handler/Furnace Blower Connecting the ERV as illustrated will ensure the Air Handler/Furnace Blower Motor is operating whenever the ERV is ventilating. CAUTION Consideration should be given to competing airflows when connecting the ERV in conjunction with an Air Handler/Furnace Blower system. The ERV must be interlocked to the Furnace/Air Handler with a Simplified Installation (Return/Return Installation) and should be interlocked with a Partially Dedicated Installation.
Balancing the Air Flows (Applicable of All Models) Balancing the air flows is critical to ensuring that the amount of air introduced from the outside of the building equals the amount of air exhausted to the outside of the building.
Balancing the Air Flows with a Pitot Tube (applicable to All Models) STEP 1. Drill a 3/16” hole in the duct (ideally 3 feet downstream of STEP 2. Insert the Pitot tube with the tip facing towards the air any elbows or bends and 1 foot upstream of any elbows or bends) in the Fresh Air and Stale air streams. Note: The duct configuration in these illustrations may stream in the Stale Air From Building air stream.
Balancing Collar Instructions Push and turn with slotted screwdriver. Damper automatically locks when pressure is released. Hard/Rigid ducting 1/2” When connecting ductwork to the collar, take note where screws are located. Screws should be located no further than 1/2” from outside edge of collar, so as not to impede operation of the damper. Insulated flexible ducting Install with the dampers fully open. Damper down the duct with the higher air flow to equal the lower air flow.
Maintenance Routine for ERV 1. Inspect Exterior Hoods at least once a month. 5. Clean Duct Work if Required Make sure exhaust and fresh air supply hoods are not blocked or restricted by leaves, grass, or snow. WARNING: Blockage of hoods may cause an imbalance. The duct work running to and from the ERV may accumulate dirt. Wipe and vacuum the duct once every year. You may wish to contact a Heating/Ventilation company to do this. 2. Clean Air Filters (clean twice a year) 6.
Troubleshooting your ERV System SYMPTOM CAUSE SOLUTION Poor Air Flows • 1/4” (6 mm) mesh on the outside hoods is plugged • filters plugged • core obstructed • house grilles closed or blocked • dampers are closed if installed • poor power supply at site • ductwork is restricting HRV • improper speed control setting • HRV airflow improperly balanced • clean exterior hoods or vents • remove and clean filter • remove and clean core • check and open grilles • open and adjust dampers • have electrician chec
