IMPORTANT -

PLEASE READ THIS MANUAL

BEFORE INSTALLING UNIT.

• Due to ongoing research and product

development, specifications, ratings, and

dimensions are subject to change without notice.

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 HRV, by using the balancing procedure found in this manual. NEVER install a ventilator in a situation where its normal operation, lack of operation or partial failure may result in the backdrafting or improper functioning of vented combustion equipment.

• Disconnect the power from the unit before cleaning or servicing.

• To prevent electrical shock, it is extremely important to confirm the polarity of the power line that is switched by the safety (disconnect) switch. The hot line (black) is the proper line for switching. Use either a voltmeter or test lamp to confirm the absence of a voltage between the disconnect switch and ground (on the cabinet) while the door is open. This procedure must be followed, as dwellings are occasionally wired improperly. Always enure the proper grounding of the unit.

• Do not apply electrical power to the unit until after the completion of the installation (including the installation of low voltage control wiring).

• Ensure the Installation and wiring is in accordance with CEC, NEC, and local electrical codes.

• Due to ongoing research and product development, specifications, ratings, and dimensions are subject to change without notice.

• Plug the unit into a standard designated (120 VAC) electrical outlet with ground.

•The use of an extension cord with this unit is not recommended. If the installation requires further wiring, have a licensed electrician make all of the electrical connections. The recommended circuit is a separate 15 amp/120 volt circuit.

Getting to Know your Heat and Energy Recovery Ventilator (FC Series)

Thank you for purchasing a Field Control Heat/Energy Recovery Ventilator (HRV/ERV). The HRV/ERV provides fresh air to your home while recovering energy from the air it exhausts. There are numerous benefits to a properly installed, operated, and maintained HRV/ERV:

• Exhausts the stale, contaminated air, found in today’s tight buildings.

Ventilation and Control Options*

Optional Controls are available to adjust the amount of ventilation in your home:

• The Healthy Home System™ Control (HHSC) will automatically deliver fresh air to your home.

• The Dehumidistat Control (DHI) can be used in conjunction with the HHSC to provide additional ventilation for high indoor humidity levels.

How the Dehumidistat Works (Colder Climates)

High indoor humidity levels, during the heating season, have become a problem in many well insulated, tight homes. Excessive condensation on the windows is a visual sign of high indoor humidity levels. High indoor humidity levels can result in mold and mildew and the eventual degradation of the building structure itself.

Your HRV/ERV reduces indoor humidity levels when the outdoor air is drier than the indoor air. These conditions usually occur during the heating season when outdoor temperatures are less than 15°C (59°F). During the heating season, the operation of the HRV/ERV may reduce indoor humidity levels sufficiently to eliminate the need for further dehumidification.

If your home requires further dehumidification, use the dehumidistat feature located on any optional main control (refer to the Operation and Installation Manual for Optional Control information). This feature aggressively addresses high indoor humidity levels by initiating high speed ventilation when the indoor humidity levels rise above the adjustable set point on the control.

• Recovers the majority of the energy contained in the exhausted stale air.

• Uses the recovered energy to preheat or precool the fresh outdoor air introduced into the house

• Distributes the fresh air throughout your home.

• The Dehumidistat Ventilation Control (DHVC) is a manual control which features ON/OFF, High speed, Low Speed, and an electronic dehumdistat.

*Refer to the individual control pages of this manual for more information about these controls.

Refer to the main control instructions located in the Operation and Installation Manual for instructions on how to set the dehumidistat. The dehumidistat function on the main control should be set to OFF for all seasons except the heating season, because a dehumidifying effect occurs only when the outdoor air is dryer than the indoor air. Set the RH level to 80 to turn the dehumidistat OFF. (Refer to the control instructions for information on how to set the Dehumidistat). DEHUMIDISTAT DISABLE - automatically disables the dehumidistat function on the main control when outdoor temperatures exceed 15°C (59°F) for a full 24 hour period. All other HRV features and functions operate normally while the dehumidistat function is disabled. DEHUMIDISTAT RE-ENABLE - automatically re-enables the dehumidistat function if either the outdoor temperature drops below 15°C (59°F) for a full 24 hour period or if the HRV is reset (unplugged for 30 seconds).

Glossary and Additional Information

DEFROST MODE - To ensure reliable operation during cold weather, the HRV automatically cycles through its defrost mode when the outdoor temperatures drop below freezing.

HRV/ERV - a Heat Recovery Ventilator (HRV/ERV) is designed to provide fresh air into a building while exhausting an equal amount of stale air. During the winter months, heat recovered from the stale air, before it is exhausted to the outdoors, warms the incoming cold fresh air. During the summer months, when the indoor space is air conditioned, the HRV/ERV helps to cool the incoming fresh air with the cool exhausted stale air.

Warranty

Heat Recovery Ventilators (HRV) carry a Lifetime Warranty on the heat recovery core and a 5 (five) year replacement parts warranty. Energy Recovery Ventilators (ERV) carry a 5 (five) year warranty

SELF-TEST - Each time the HRV/ERV is powered/energized, the self-test function automatically initiates. The HRV/ERV cycles through the available speeds and tests the damper motor operation. The HRV/ERV defaults back to the previous operational mode and speed selection after the self-test (approximately 60 seconds in duration).

STANDBY - The HRV/ERV is powered/energized and waiting for ventilation to be initiated by an external control.

TIMERS - These optional controls may be installed at specific exhaust locations (bathrooms etc.) to initiate high speed ventilation.

Setting the Control

The duration of the ventilation rate is adjustable on the HHSC. Your installer sets up this control during the installation of your system . Refer to the instructions that came with the HHSC for the setup information.

Dehumidistat (Part DH1)

The Healthy Home System™ Control (HHSC)

Your HRV/ERV system produces a dehumidifying effect when outdoor humidity levels are lower than indoor humidity levels. These conditions occur normally when outdoor termperatures are below 60°F. An additional dehumidification effect is achievable with the Optional Dehumidistat (Part DH1).

The Optional DH1 Control may be combined with the Healthy

Home System Control (HHSC). The DH1 will initiate high speed

ventilation when the moisture level in the home exceeds the set

point on the control. Once the humidity in the house is reduced,

the HRV will revert back to the HHSC automatic setting. The

Dehumidistat should be set to OFF for all seasons except the

heating season.

Maintenance Routine for HRV

Electric shock hazard. Can cause injury or death. Before attempting to perform any service or maintenance, turn the electrical power unit OFF at disconnect switch(es). Unit may have multiple power supplies.

WARNING

1. Inspect Exterior Hoods at least once a month.

Make sure exhaust and fresh air supply hoods are not blocked or restricted by leaves, grass, or snow. In winter, it is especially important to make sure snow is not blocking the hoods or that frost has not built up on the wire mesh (bird screen).

WARNING: Blockage of hoods may cause an imbalance.

2. Clean Air Filters (clean twice a year)

The standard filters equipped with your HRV are removable and washable.

a) simply open access door and slide core out

b) remove filter clips

c) once clips are removed filters can be taken off the core to be

rinsed with water or a combination of mild soap and water. Do not clean in the dishwasher

d) to re-assemble, place clean filter(s) (wet or dry) back into their

positions against the core and return clips to their original position

e) slide core back into its’ original position

3. Clean Core Twice a Year

a) open access door.

b) carefully grip ends of core and pull evenly outward. Core may

be snug, but will slide out of the channel

c) once removed from the cabinet remove filters

d) wash core in warm soapy water (do not use dishwasher)

e) install the clean filters

f) install clean core

Note: Core installation label on the outer end of the core.

To install the clean core:

a) first mount the bottom flange of the core guide into the bottom

H channel approximately 1/4” (6mm)

b) mo unt t he left or ri ght s id e fla ng e of th e cor e guide

approximately 1/4” (6mm) followed by the other side

c) mount the top flange of the core guide into the top H channel

approximately 1/4” (6mm).

d) with all four corners in place and the core straight and even,

push hard in the centre of the core until the core stops on the back of the cabinet.

NOTE: Core will appear to stick out from cabinet approximately 1/8” (3mm). This is designed this way so that the access door will fit tight against the core.

4. Motors - Maintenance Free

6. Clean Duct Work if Required

The duct work running to and from the HRV may accumulate dirt.

Wipe and vacuum the duct once every year. You may wish to

contact a Heating/Ventilation company to do this.

7. General Maintenance - Twice a Year

Wipe down the inside of the cabinet with a damp cloth to remove

dirt, bugs, and debris that may be present.

8. Cleaning the Fans

Fans may accumulate dirt causing an imbalance and/or excessive

vibration of the HRV. A reduction in the air flow may also occur.

In new construction this may result within the first year due to

heavy dust and ma y oc cur peri odically after that ov er time

depending on the outdoor conditions.

• unplug the HRV and open the service door

• remove the core

• remove ducting (metal and/or flexible insulated type) from the red and/or blue ports which are connected immediately in-line with the fan assembly

• use a small brush, such as an old toothbrush or pipe cleaner, and insert first

(a) through the lar ge o pe ning of the fan

assembly and then

(b) th rough the sma ll er o pe ning in the end

of the fan assembly.

• scrub individual fan blades until clean. Avoid moving or damaging balancing flat weight, clip is usually found on one or more of the fan blades

• vacuum and wipe

• reassemble making sure ducting is reattached firmly and insulation and moisture barrier are sealed and taped

Before attempting this task, thought should be given to having a qualified service technician complete the service work.

5. Drain (condensate) Line - Clean once a year

Inspect drain line, drain spout, and “P” trap for blockage, mould or kinks. Flush with warm soapy water and replace if worn, bent or unable to clean.

Port Configuration and Airflow Model FC95HRV

In order to make the HRV as space efficient as possible, the INDOOR supply and return ports are converted from round to oval shape. Overall size of the port remains the same. Simply bend a standard duct fitting to the correct shape, and attach to the oval port using the same method as for a round port.

Round port bent to oval

FC95HRV Air Flow

Stale air enters the FRONT-RIGHT side port. The air passes down

the front half of the core, then up the back half of the core and out

the RIGHT-REAR port.

Fresh outdoor air enters the LEFT-REAR port and passes down

the back half of the core. Then the fresh outdoor air passes up the

front half of the core and out the LEFT-FRONT port. This

configuration allows the air to actually travel through the core

twice, which makes the FC95HRV nearly as efficient as a double

core unit.

Installation Methods

ATTENTION

The Three Methods of Installation

Th e fo ll owing three installation m ethods are for the HRV/ERV system:

• The Simplified installation.

• The Partially Dedicated Installation

• The Fully Dedicated Installation

Simplified Installations

The Simplified Installation draws stale air from the cold air return duct of the air handler/furnace and introduces an equal amount of fresh air farther downstream into the cold air return. Refer to "Simplified Installation Diagrams".

The air handler/furnace blower must be running when the unit is operating for this system to be effective. Refer to

"Interlocking the HRV/ERV to an Air Handler/Furnace Blower".

Partially Dedicated Installations

The Partially Dedicated Installation draws stale air from specific points in the house and introduces an equal amount of fresh air into the cold air return. Refer to "Partially

Dedicated Installation Diagrams".

Stale air ducts should be installed in areas of the home where the poorest indoor air quality exists (bathrooms and kitchen). Each location with a stale air duct should have a timer to initiate high speed ventilation. Refer to "Optional Timers" in this manual.

The air handler/furnace blower should be running when the HRV is ope rating to eve nly dis tr ibute the f re sh air throughout the house. Refer to "Interlocking the HRV/ERV to an Air Handler/Furnace Blower".

Fully Dedicated Installations

The Fully D edicated Installation draws stale air from specific points in the house and delivers fresh air to specific locations of the house. This system is not connected to an air h andle r/f urnac e. Re fer to " The Ful ly D edi cated Installation Diagrams" in this manual.

Installing the Ducting Between the HRV/ERV & Living Areas in the House

A well designed and installed ducting system will allow the HRV/ERV to operate at its maximum efficiency.

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. Use "Y" tees instead of straight tees whenever possible.

All duct joints must be fastened with screws, rivets or duct sealant and wrapped with mastic or quality duct tape to prevent leakage. Mastic is preferred but if duct tape is used, we recommend aluminum foil duct tape.

Galvanized (rigid) ducting from the HRV/ERV to the living areas in the house is recommended whenever possible althoug h flexibl e du ct c an b e used i n moderat ion if necessary.

A short length (approximately 12 inches or 300mm) of nonme ta llic flexible ins ul at ed duc t should be c on ne ct ed between the HRV/ERV and the supply/exhaust duct system to avoid possible noise transfer through the duct system.

All ducts running through attics and unheated spaces must be sealed and insulated to code.

Applicat ion s such a s gre enh ous es, a tri ums , swi mming p ool s, s aun as, etc. have uni que ven tilation requirement s whi ch sho uld be addressed with an isolated ventilation system.

Stale air ducts should be installed in areas of the home where the poorest indoor air quality exists (bathrooms and kitchen). Each location with a stale air duct should have a timer which will initiate high speed ventilation. Refer to "Optional Timers" in this manual.

Fresh air ducts should be installed to all bedrooms and living areas, excluding bathrooms, kitchen and utility areas. Grilles sh ould be located high on a wall or in ceiling locations. Grilles t hat diffus e the air comfo rtably are recommended. Refer to "Grilles" in this manual. Special care should be taken in locating grilles if the floor is the only option available. Areas such as under baseboard heaters will help to temper the air.

Optional in-line duct heaters are available for mounting in the supply duct work to add heat if required.

DIRECT CONNECTION of both the HRV SUPPLY AIR STREAM and

EXHAUST AIR STREAM to the FURNACE COLD AIR RETURN

Installation Notes

• Unit is normally balanced on HIGH speed with the furnace blower ON.

• A minimum separation of 40 inches (1m) is recommended between the two direct connections.

• The exhaust air connection should be upstream of the supply air connection to prevent exhausting any fresh air.

• Weatherhood arrangement is for drawing purposes only. Six feet (2m) minimum separation is recommended. The Weatherhood must also be 18" (460mm) above grade minimum.

• The airflow must be confirmed on site using the balancing procedures found in this manual

Key Points

• The HRV/ERV must be balanced.

• It is mandatory that the furnace blower run continuously or HRV/ERV operation be interlocked with the furnace blower. (Refer to “Interlocking the HRV/ERV to an Air Handler/Furnace Blower.”)

• The duct configuration may change depending on the HRV/ERV model. See specifications for your unit.

• Check local codes / authority having jurisdiction for acceptance.

• A backdraft damper is required in the exhaust air duct to prevent outdoor air from entering the unit when the Furnace/Air Handler is running and the unit is in Standby, OFF or Recirculate.

Sizing the Ductwork

It is the responsibility of the installer to ensure all ductwork is sized and installed as designed to ensure the system will perform as intended.

The amount of air (cfm) that an HRV/ERV will deliver is directly related to the total external static pressure (E.S.P.) of the system. Static pressure is a measure of resistance imposed on the blower by length of duct work plus the number of fittings used in the duct work.

Location

Install the unit in a heated space that provides convenient space for service access. A typical location is in either a mechanical room or an area close to the outside wall within close proximity to where the weatherhoods are mounted. If a basement area is inconvenient or non- existent, install the unit in a utility or laundry room.

Attic installations are not recommended due to:

A) the complexity of work to install

B) freezing conditions in the attic

C) difficulty of access for servicing and cleaning

Leave sufficient clearance at the front of the access door for servicing the air filters and core. The recommended clearance is a minimum of 25" (635 mm) for opening and closing the door. Field Controls provides four straps for hanging the unit from the basement floor joists.

Suspend the Unit with the Adjustable Hanging Straps

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.

STEP 1. Insert the screws and washers (not included) through

the Hanging Strap grommets and fasten to the joists.

STEP 2. Unscrew the 4 machine screws located on the upper

side of the unit. Attach the "S" hooks and reinsert the machine

screws.

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. Repeat at opposite end of the unit.

Note: Do not pull the Hand Loops in a horizontal or lateral direction during the installation/adjustment process.

STEP 4. Level the unit from left to right and front to back.

- Adjust the unit down by lifting up on the buckle.

- Adjust the unit up by pulling down vertically on the Hand Loops while lifting up the bottom of the cabinet.

STEP 5. Fold the hand loops and excess strap and secure with a

nylon tie (not included).

CAUTION

Do not mount exhaust grille within 4’ (1.2m) (horizontally) of a stove to prevent grease from entering the unit.

Drain Connection

The HRV may produce some condensation during a defrost cycle. This water should flow into a nearby drain, or be taken away by a condensate pump.

The HRV cabinet has prepunched holes for the drain (see below). Insert the drain spout through the hole in the drain pan. Be sure to install the "O ring" which seals each spout to the pan. HAND TIGHTEN the washer and lock nut which hold the drain spout in place.

Construct a P-Trap using the plastic tee connector. Cut two lengths of 1/2" drain hose (not included) and connect the other ends to the two drain spouts. Position the "T" fitting to point upward and connect the drain line. Tape or fasten base to avoid any kinks. Pour a cup of water into the drain pan of the HRV after the drain connection is complete. This creates a water seal which will prevent odors from being drawn up the hose and into the fresh air supply of the HRV.

Grilles

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.

Field supplied balancing dampers should be installed external to the unit to balance the amount of stale air being exhausted with the amount of fresh air being brought into the house. Refer to Air flow Balancing section.

Note: Secondary drain pan may be required to protect from condensate leakage.

The Techgrille

The TECHGRILLE is a round, fully adjustable grille, which provides superior, quiet air distribution.

ATTENTION

Installing the Ducting from the Weatherhoods to the HRV/ERV

The inner and outer liners of the flexible insulated duct must be clamped to the sleeve of the weatherhoods (as close to the outside as possible) and the appropriate port on the HRV/ERV. It is very important that the fresh air intake line be given special attention to make sure it is well sealed. A good bead of high quality caulking (preferably acoustical sealant) will seal the inner flexible duct to both the HRV/ERV port and the weatherhood prior to clamping.

To minimize air flow restriction, the flexible insulated duct that connects the two outside weatherhoods to the HRV/ERV should be stretched tightly and be as short as possible.

Twisting or folding the duct will severely restrict air flow.

Hard (rigid) ducting which has been sealed and insulated should be used for runs over 10’ (3.3 m). Refer to your building code.

Intake Weatherhood Requirements

• Should be located upstream (if there are prevailing winds) from the exhaust outlet

• At least 6' (2 m) from the exhaust weatherhood

• At least 6' (2 m) away from dryer vents and furnace exhaust (medium or high efficiency furnaces)

• A minimum of at least 6' (2 m) from driveways, oil fill pipes, gas meters, or garbage containers

• At least 18" (460 mm) above the ground, or above the depth of expected snow accumulation

• At least 3' (1 m) from the corner of the building

• Do not locate in a garage, attic or crawl space

Exhaust Weatherhood Requirements

• At least 6' (2 m) from the ventilation air intake

• At least 18" (460 mm) above ground or above the depth of expected snow accumulation

• At least 3' (1 m) away from the corner of the building

• Not near a gas meter, electric meter or a walkway where fog or ice could create a hazard

• Not into a garage, workshop or other unheated space

When installing the weatherhood, its outside perimeter must be sealed with exterior caulking.

Installation of the Healthy Home System™ Control (HHSC)

Choose a Location

The HHSC controller can be installed anywhere in your home. To simplify the installation, locate the HHSC control near the HVAC system and/or the HRV/ERV, since the HHSC does not require routine adjustment or occupant interaction.

To provide the occupants with direct access to the functions of the controls, install optional accessory controls throughout the house.

How To Install the Controller

1. Separate the HHSC controller cover from the wall plate (mounting base) to expose mounting holes (see illustration).

2. Route wires through large hole in the mounting base. Mount base against wall and mark wall through 3 mounting holes.

3. If mounting on a metal or wood surface, drill three 1/8-in. pilot holes in wall where marked for the supplied mounting screws. If mounting on drywall or other surface, drill appropriate holes for wall anchors or other means of attachment.

4. Secure mounting base to wall with either the 3 screws provided or other fasteners, while ensuring that all wires extend through the hole in mounting base.

5. Adjust length and routing of each wire to reach the proper terminal and connector block on mounting base, while leaving a 1/4 in. length of extra wire. Strip only 1/4 in. of insulation from each wire to prevent adjacent wires from shorting together when connected.

6. Connect wires to their respective terminals on the connector block. (Figure 1) Both (R) and (C) must be connected for proper operation. Improper wiring or installation may damage the controller. Ensure wiring is correct before proceeding with installation or turning the unit on.

7. Push any excess wire into wall and against mounting base.

8. Snap cover onto base, while ensuring pins align with sockets in connector.

9. Once powered the HHSC automatically enters into operating mode.

HRV/ERV control. The HHSC is also typically used to control an FAD fresh air damper.

2. Complete all wiring connections before restoring power to the HVAC system and HRV/ERV.

Programming the HHSC Control

1. Balance the fresh and stale airflows as instructed in this manual.

2. Determine the cfm flow rate as instructed in this manual.

3. To obtain the desired rate of fresh air exchange, refer to the HHSC Control Installation Instructions to determine the On/Off timer settings for the HHSC Control. Use the

cfm flow rate determined in step 2 as the computed or

measured fresh air flow rate (as calculated in the HHSC instructions). To ensure adequate ventilation, ensure that the “Fan On” time is equal to or greater than the “Vent On” time, as programmed in the HHSC Control.

4. For continuous operation of the HRV/ERV, set “Fan On” and “Vent On” to “Un” (unlimited), and “Fan Off” and “Vent Off” to any setting except “Un”. This setting also causes the HVAC fan to run continuously.

NOTE: The HHSC Control is factory programmed with the default settings of the two On/Off timer values. No configuration is required to use these factory default settings.

Default settings: FAN OFF 20 minutes FAN ON 10 minutes VENT ON 10 minutes VENT OFF 20 minutes

Complete the Wiring Connections

1. Refer to subsequent wiring diagrams in this manual that correspond to the desired control configuration.

CAUTION

Connecting the HRV/ERV as illustrated will ensure the Air Handler/Furnace Blower Motor is operating whenever the HRV/ERV is ventilating.

The HRV/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.

Consideration should be given to competing air flows whe n con nec tin g the H RV/ ERV i n conjunction with an Air Handler/Furnace Blower system.

Setting “Standby” when using a Main Control

The HRV/ERV will be “fully-off” when the OFF position is selected on the Main Control. Timers and /or other controls will not function when the HRV/ERV is in the OFF position. The “fully-off” feature can be modified to “s ta nd by-off” by adding a j um pe r on the Terminal Block between 2 (ON) and 3 (RED). “Standby” can also be achieved by setting the main control to the ON position and selecting speed 0*. Timers and /or additional controls

Building codes in some areas require “fully-

off” functionality. Check with your local

building authority before modifying the unit

to “standby -off”.

Unintentional operation of the HRV by the

end user may occur if the unit is modified

from “fully-off” to “standby-off”.

Balancing the Air Flows

ATTENTION

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. If these two air flows are not properly balanced, the following issues may occur:

• A positive or negative pressure may occur in the house

• HRV/ERV may not operate at its maximum efficiency

• The unit may not defrost properly

Air Flow Measuring Gauges

The magnehelic gauge and the digital manometer are suitable instruments for the balancing of air flows.

A magnehelic gauge with a scale of 0 to .25" w.c. is suitable for accurately measuring air duct velocity. The value on the gauge will be velocity pressure. A digital manometer requires the ability to display differential pressures at 3 digits of resolution.

Gauge Attachments

When sampling an air flow, various attachments are available for use on a magnehelic gauge or digital manometer.

The following illustration shows a magnehelic gauge with a scale of 0 to .25" w.c. with a pitot tube attachment. This combination will measure the system air velocity pressure accurately, regardless of the duct size or shape (either round or rectangular).

Continuous, excessive, positive pressure may drive moist indoor air into the external walls of the building. Once inside the external walls, moist air may condense (in cold weather) and degrade structural components or cause locks to freeze. Continuous, excessive, negative pressure may have several undesirable effects. In some geographic locations, soil gases such as methane and radon gas may be drawn into the home through basement or ground contact areas, and may also cause the backdrafting of vented combustion equipment.

Balancing Preparation

Prior to performing the air balancing procedure, perform the following steps:

• Seal the ductwork system

• Confirm the installation and proper operation of all the

components of the HRV/ERV

• Fully open the balancing dampers

• Turn off all household exhaust devices (range hood, clothes

dryer, bathroom fans)

• Set the HRV/ERV at high speed

• Prior to balancing the unit, first adjust air flows in branch

lines to specific areas of the house

• If the outdoor temperature is below 0˚C (32˚F), ensure the

unit is not running in defrost

• Place the magnehelic gauge on a level surface and adjust it

to zero

• If t he s ys tem is a S impli fied o r Parti al ly D edicate d

installation, operate the furnace/Air Handler at high speed

Balancing the Air Flows with a Pitot Tube

STEP 1. D

rill a 3/16” hole in the duct (ideally 3 feet downstream of

ny elbows or bends and 1 foot upstream of any elbows

or bends) in the Fresh Air and Stale air streams.

Stale Air From Building

Fresh Air to Building

Drill 3/16” holes in Stale & Fresh Air ducts.

STEP 2. Insert the Pitot tube with the tip facing towards the air

stream in the Stale Air From Building air stream. Move the Pitot tube around in the duct (facing towards the airflow) and take an average reading. Record the reading.

Magnehelic Gauge must be level.

owards the air stream.

STEP 3. Repeat Step 2 to measure the Fresh Air to Building duct.

Magnehelic Gauge must be level.

STEP 4.

A) Review the readings and damper down the duct with the highest duct velocity pressure. Repeat Step 2 and Step 3 until both ducts show indentical readings. For this example, the Fresh Air to Building air stream has the highest duct velocity pressure.

B) Upon completion of balancing, seal the holes (foil tape recommended).

Determining the cfm

After balancing the air flows, calculate the cfm flow rate.

Example

This example shows how to determine the air flow for a 6” diameter duct. As shown in the illustration, the duct velocity pressure reads 0.025” w.c. on the magnehelic gauge. Use the chart that came with the magnehelic gauge to determine a duct velocity of 640 feet per minute for a duct

velocity pressure of 0.025” w.c.

Cfm Calculation

cfm = feet per minute x cross section area of duct

Cross Section Area of some common round duct sizes:

0.087 for 4” diameter duct

0.136 for 5” diameter duct

0.196 for 6” diameter duct

0.267 for 7” diameter duct

= 640 x 0.196 = 125

Illustration of a door with door ports

Door balancing ports (not on all models) are designed to be used in conjunction with a Magnehelic Gauge or Digital Manometer to

measure the Stale and Fresh airflows for balancing.

Step 1

Prepare the air flow measuring device (i.e. Magnehelic Gauge or Digital Manometer) by connecting the hoses to the low and high pressure side of the gauge.

Step 2

Insert the hoses into the rubber fittings from the optional Door Port Adapter Kit (part # 99-182). Use light pressure and rotate until fitting is snug. Do not extend the hose past the rubber fitting.

Step 3

Open the HRV Door. Remove the 4 Door Port Covers by carefully pushing them out from the back side of the door (use the blunt end of a large drill bit etc.).

Step 4

Close the HRV Door. Initiate power and operate the HRV on high speed. Operate the forced air system on high speed (if the HRV is connected to the forced air system) .

Step 5

Insert the 2 rubber fittings from the gauge to the STALE AIR Balancing Ports (upper right and lower left). Seal the FRESH AIR Balancing Ports (upper left and lower right) with tape. Record your reading.

Step 6

Insert the 2 rubber fittings from the gauge to the FRESH AIR Balancing Ports (upper left and lower right). Seal the STALE AIR Balancing Ports (upper right and lower left) with tape. Record your reading.

Step 7

Refer to the "Airflow Reference Chart" for your model and determine the FRESH AIR and STALE AIR flow rates (the chart is located on the lower portion of this page).

Step 8

Damper down the higher airflow and repeat Steps 5 to 7 as required until both airflows are identical (balanced).

Step 9

Remove the tape and rubber fittings and reinstall the 4 Door Port Covers.

Balancing Dampers

NOTE

The FC155HRV and FC200HRV models have factory installed Balancing Dampers located in the “Fresh Air to Building” and “Stale Air from Building” collars.

All other units require the installation of balancing dampers (not included) in the “Fresh Air to Building” and “Stale Air from Building” ductwork. Refer to the installation diagrams in this manual for the Simplified, Partially Dedicated, and Fully Dedicated systems.

Installations where the HRV is ducted directly to the r etu rn of the furna ce/ Air Handler may require additional dampening on the fresh air to building duct. This is due to the high return static pressures found in some furnace installations.

Push and turn with slotted screwdriver. Damper automatically locks when pressure is released.

Illustration of Adjusting the Factory Installed Balancing Damper

Observe the location of the screws when connecting ductwork to the collar. Screws should be located no further than 1/2” from the outside edge of the collar and they should be no longer than 3/4”.
