CAUTION

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 airflow’s of the Heat Recovery Ventilator (HRV) Energy Recovery Ventilator (ERV) by using the balancing procedure found in this manual.

It is always important to assess how the operation of any HRV/ERV may interact with vented combustion equipment (ie. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.).

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!!!

IMPORTANT - PLEASE READ THIS MANUAL BEFORE INSTALLING UNIT.

HRV - Aluminum Core

A Heat Recovery Ventilator (HRV) is designed to provide fresh air into a building while exhausting an equal amount of stale air. During the winter months, the incoming cold fresh air is warmed by utilizing the heat recovered from the stale air before it is exhausted to the outdoors. During summer months when the indoor space is air conditioned, the Heat Recovery

Ventilator will help in cooling the incoming fresh air with the stale air that is being exhausted.

ERV - Enthalpic Paper Core

An Energy Recovery Ventilator (ERV) is designed to provide fresh air into a building while exhausting an equal amount of stale air. An ERV is designed for use in warm humid areas with heavy air conditioning use. The ERV will transfer both sensible and latent heat from the incoming fresh air to the outgoing stale air thereby reducing the load (due to ventilation) on the air conditioning system.

ERVs are not suitable for climates where the temperature drops below -4°C (25°F).

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

All Energy Recovery Ventilators carry a 5 (five) year warranty on the energy recovery core and a 5 (five) year replacement parts warranty.

During the warranty period, if any core experiences a failure or perforation caused by normal use while owned by the original purchaser, a replacement core (FOB our plant) will be supplied at no expense.

What is the difference between an HRV and an ERV?

The core in an HRV (Heat Recovery Ventilator) transfers heat from one air stream to the other. This is called sensible heat. The term ERV (Energy Recovery Ventilator) is usually used to describe a unit with an enthalpic core that transfers moisture as well as heat from one air stream to the other. This (moisture transfer) is called latent heat.

Enthalpic - what does it mean?

Enthalpy is the term used to describe the energy content of air. This energy is a combination of the sensible and latent heat. Therefore, a core which transfers energy is called an enthalpic core.

Is an ERV better than an HRV?

NOT NECESSARILY! In cold climates such as most of North America, an HRV works better than an ERV. This is because the air inside the home during the winter months will be more humid than the outside air. An ERV would transfer the latent heat (humidity) from the exhaust air back into the incoming airstream. This will aggravate moisture problems in the home and encourage the growth of mold and mildew. If the air in the home is too dry for comfort, an ERV will not help. A humidifier should be used to increase the humidity to a comfortable level.

Where do you use an ERV instead of an HRV?

An ERV is recommended for warm, humid areas with heavy air conditioning use. As there is no defrost in an ERV it is not recommended for areas where the temperature drops below -4°C (25°F).

Why transfer moisture in the summer (cooling season)?

The enthalpic core will allow moisture to be transferred from a humid air flow to a dry air flow. This property is useful in the cooling season if an air conditioning system is used to lower the indoor humidity. You will then have dry, cool air in the exhaust of the ERV, and warm humid air in the supply stream. With these conditions, the ERV will be able to transfer the moisture and heat of the supply air to the exhaust air. In this way, the ERV will supply to the home air which is cooler and drier than outside. Remember that an ERV is not a dehumidifier, and on its own will not take moisture out of the air.

So why use an ERV?

A properly operating air conditioner will not only lower the temperature in your house, but will also lower the humidity level. This prevents an uncomfortable cold

and damp situation. In fact, about 2/3 of the energy used by the air conditioner system is to remove moisture. Therefore, when ventilating in the summer, less moisture brought into the home means less work for the air conditioner, and energy savings for you.

During the winter, an ERV recovers some humidity from the exhaust air, reducing the need for humidification, if the required ventilation rate would make the home too dry.

What's the difference between this type of core and a rotary type?

Here's a list of characteristics of the fixed plate core.

1. No rotating parts, so maintenance is easy and the unit lasts a long time.

2. It is very flexible in terms of installation.

3. The core can easily be changed.

4. Because the supply and exhaust air streams are completely separate, there is very little cross leakage of any dust or germs.

Can the core become clogged with dust?

Because the surface of the core is a turbulent flow area, dust sticks to it easily; however, because the inside of the element is a laminar flow area, virtually no dust sticks to it.

What is the maintenance?

About once a year you should use a vacuum cleaner to remove the dust from the core's surface. DO NOT WASH WITH WATER!

Is an air filter needed?

To prevent clogging of the core, an air filter should always be installed on the supply and exhaust sides of the core.

How much ventilation do I need?

During seasons when your windows and doors are closed, the ERV should operate continuously when the dwelling is occupied, and either continuously or intermittently when not occupied.

For most installations the ERV will normally be set to operate continuously on low speed with the option of going to high speed as the need arises. For example; if you are entertaining and there is a large number of people present (some may be smoking), the unit should be switched to high speed.

Your ERV may be equipped with automatic or manual switches, but all ERVs will have a manual speed control override.

Operating the ControlAir 15

Plugging in the HRV/ERV energizes the unit. A self test function will be performed every time the HRV/ERV is energized (refer to “Self Test” for more details). After the self test has completed successfully the HRV/ERV will default to Speed 1. This is the factory default setting. Follow the instructions found on the HRV/ERV door to select desired mode and speed, or refer to the instructions found on the following page.

Removing and relocating the Control Pad

The Control Pad can be removed and installed in a remote location (100’ wire length max). The Control Pad can be installed in a 2x4 box with a “Decora” type cover plate or can be installed in the optional “Ventilation Dehumidistat” or “Air Sentry”. When the Control Pad is installed in a remote location, all optional controls will still be wired to the Control Module on the HRV/ERV. When remotely mounted on its own, the Control Pad is wired to the Control Module by 3 wire (min. 20 gauge). Connect the colour coded terminals to the corresponding terminals on the Control Module. When the Control Pad is remotely mounted in the Ventilation Dehumidistat or Air Sentry, refer to optional controls page for wiring requirements.

Self Test

Each time the

HRV/ERV

is powered/energized the self test function will automatically initiate. During the self test the

HRV/ERV

will cycle through all the speeds available (1-5), test the damper motor operation and will default back to the previous mode/speed selection, (factory default is Speed 1). Total self test duration is approximately 1 min. 30 sec.

Automatic Defrost Operation

(Not on all models)

The advanced technology of the digital microprocessor automatically activates the defrost system only as it is needed. To be an efficient heat recovery device, the HRV/ERV must effectively provide for core defrost as well as providing efficient heat exchange. As outdoor conditions cool, the temperature sensor (thermistor) tracks the supply air temperature. The thermistor then sends its signal to the microprocessor (circuit board) which initiates only the defrost cycle time required to clear the core. On recirculating defrost models, the core is defrosted when the supply air port is automatically blocked off and exhaust air is redirected back through the HRV/ERV. On damper defrost models, the core is defrosted when the supply air port is automatically blocked off and the warm air surrounding the HRV/ERV is drawn in through the defrost port. The mode indicator will flash RED during the defrost cycle. By optimizing the defrost cycle, the HRV/ERV combines money saving performance with a well designed and reliable control system.

Glossary

DEFROST MODE - to ensure reliable operation during cold

weather, the HRV/ERV will automatically cycle through its defrost mode as needed. (not on all models)

DEHUMIDISTAT - a control device that senses the amount of moisture in the air and will activate high speed fan operation when the air moisture level exceeds the control setting. The optimum air moisture level (or relative humidity [Rh]) in the typical home is in the range of 30 to 50% Rh.

RESET - whenever resetting of the HRV/ERV is required, simply disconnect power for 30 seconds.

STANDBY MODE - the HRV/ERV is energized and waiting for fan operation to be initiated by a remote device or manual override.

THERMISTOR

- the

HRV/ERV

's temperature sensor which measures electrical resistance in a known manner, as outdoor temperatures fluctuate.

Connects to RED and BLACK terminals. Use a two 18 gauge low voltage wire. Mounts ina2x4box. The crank timer provides a solution to installing a system where only 2 wires are present for the timers.

ControlAir 15 Optional Remote Controls

Optional Main Controls

The amount of ventilation required in your home will fluctuate according to the activity level in the house. Higher activity levels require more ventilation.

Main controls can be mounted in a central location of the home (i.e. beside the furnace thermostat) which will provide the user with complete control over their ventilation system from a convenient location.

Optional Timers

Timers should be present when the HRV/ERV is exhausting from speciific locations i.e bathrooms, laundry rooms. The Digital Electronic Timer is the best selection, however, the crank timer will be necessary if only 2 lead low voltage wires are present.

Dehumidistat Dial

The dehumidistat is used to reduce high winter humidity levels. The dehumidistat activates high speed ventilation when the indoor humidity level exceeds selected setting.

Knockout for the Control Pad

The control pad from the HRV/ERV fits into this knockout giving full functionality and control of the HRV/ERV from a remote location.

Some models have a built-in dehumidistat (an optional remote wall mount dehumidistat can be installed, see Optional Remote Controls), to control harmful, excess humidity during the heating season. The dehumidistat operates in % of RH (relative humidity) with 80 being high and 20 being low. The average person is comfortable between 30-50%.

The dehumidistat will override the ventilator to high speed when the moisture level in the home exceeds

the set point on the control. Once the humidity in the house is reduced, the HRV/ERV will revert back to its previous setting.The dehumidistat should be set to off for all seasons except the heating season.

Note: If your HRV/ERV is equipped with an internal and an external dehumidistat, the internal one can be turned off and not used.

95 MAX Port Specifications

The 95 Max Heat Recovery Ventilator (HRV) has been designed to allow the installer to choose between two possible positions on the cabinet for the INDOOR EXHAUST (return from building) port. Illustrations in this manual show standard (side mounted) port location. The same specifications apply to both 95 Max setups,

regardless of which port position is selected.

Variable Port Location / Installation (Model 95 Max only)

The exhaust return port collar is not factory installed. Installer may choose either side mounted or alternate top mounted port by simply removing one of the two knock-out plates and attaching a port collar (supplied). To remove knock-out plate, insert a utility knife into the knock-out slits and trace them completely to puncture protective film underneath. Then, cut the solid tabs between the slits, using tin snips or side cutters, and

remove the knock-out plate. If any protective film still blocks the opening, remove it now.

In order to make the 95 Max 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.

95 MAX Air Flow

Stale air enters the FRONT RIGHT side port. The air will pass down the front half of the core, then up the back half of the core and out the RIGHT REAR port.

Fresh outdoor air will enter the LEFT REAR port and pass down the back half of the core. It will then pass up the front half of the core, and out the LEFT FRONT port. This unique configuration allows the air to actually travel through the core twice, making the 95 MAX almost as efficient as a double core unit.

Location

The HRV/ERV must be located in a heated space where it will be possible to conveniently service the unit. Typically the HRV/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 or laundry room may be used.

Attic installations are not normally recommended due to:

A) the complexity of work to install

B) freezing conditions in the attic

C) difficulty of access for service and cleaning

Sufficient clearance at the front of the access door is required for servicing the air filters and core. A minimum of 25" (635 mm) clearance is recommended so the door can be opened. Four PVC reinforced polyester hanging straps are provided for hanging the HRV/ERV from the basement floor joists.

Mounting

The hanging straps should be attached to the unit at the top end corners (mounting screws are already located on the HRV/ERV case). Securely fasten the other end of the straps to the floor joists with wide head nails (not supplied), making sure the unit is level. The straps are designed to reduce the possibility of noise, resonance or harmonics; therefore using the full length of the strap between the HRV/ERV and the floor joists is recommended.

Electrical

The HRV/ERV should be plugged into a standard designated (120VAC) electrical outlet with ground. It is not recommended that an extension cord be used for this appliance. If further wiring is required, then a licensed electrician should make all electrical connections. It is recommended that a separate 15 amp/120 volt circuit be used.

WARNING:

In order to prevent electric shock when cleaning or servicing the HRV/ERV, 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 to be switched. To confirm the proper polarity, use a voltmeter or test lamp to ensure there is no power after the switch when the door is open. Check between that point and ground (on the cabinet). This must be done as dwellings are occasionally wired improperly. Always make sure that the HRV/ERV is properly grounded.

Connecting Appliances to the HRV/ERV

It is not recommended that any of the following appliances be connected to the HRV/ERV:

• clothes dryer

• range top

• stovetop fan

• central vacuum system

Lint, dust or grease will collect in the HRV/ERV, damaging the unit.

NOTE:

Connecting any of these to the HRV/ERV will invalidate your warranty.

Installing the Drain Line and P-Trap

(not on all models)

When defrosting, the HRV/ERV may produce some condensation. This water should flow into a nearby drain, or be taken away by a condensate pump. The HRV/ERV and all condensate lines must be installed in a space where the temperature is maintained above the freezing point.

At the bottom of the cabinet there are prepunched hole for the drain pan connectors (see below). Insert the drain spout through the hole in the drain pan. Do not forget the “O Ring” which seals the connector to the pan. REMEMBER TO HAND TIGHTEN ONLY the washer and lock nut which hold the drain connector in place.

Construct a P-Trap using the plastic tee connector. Cut two lengths of hose and connect each piece to an end of the “T” fitting, then connect the other ends to the two drain spouts. Allow the "T" fitting to point upwards, and connect the drain line. Tape or fasten base to avoid any kinks. This creates a “trap” which will hold some condensate and prevent odours from being drawn up the hose and into the fresh air supply of the HRV/ERV.

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

Always try to keep duct runs as short and straight as possible.See Installation Diagrams for various installation options.

Outside Weatherhoods

The fixed covered hoods have a built-in bird screen with a 1/4" (6 mm) mesh to prevent foreign objects from entering the ductwork.

Locating the Intake Weatherhood

• 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" (457 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

Locating the Exhaust Weatherhood

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

• At least 18" (457 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.

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. See below for the recommended connection of flexible insulated ducts to the the outside weather-

hoods and the HRV/ERV.

Warmside Ducting

To maximize airflow in the ductwork system, all ducts should be kept short and have as few bends or elbows as possible. Forty-five degree elbows are preferred to 90° elbows. Use “Y” tees instead of 90° elbows whenever possible.

All duct joints must be fastened with screws, rivets or duct sealant and wrapped with a quality duct tape to prevent leakage. We recommend aluminum foil duct tape.Galvanized ducting from the HRV/ERV to the living areas in the house is recommended whenever possible, although flexible duct can be used in moderation if necessary.To avoid possible noise transfer through the ductwork system, a short length (approximately 12 " or 300 mm) of non-metallic flexible insulated duct should be connected between the HRV/ERV and the supply/ exhaust ductwork system.

The main supply and return lines to/from the HRV/ERV must be 6 inches (150 mm) minimum. Branch lines to the individual rooms may be as small as 4 inches (100 mm), but 5 inch (125 mm) lines are preferred .

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

In homes without a forced air furnace, fresh air should be supplied to all bedrooms and living areas, excluding bathrooms, kitchen and utility areas. It should be supplied from high wall or ceiling locations. Grilles that diffuse the air comfortably such as the Techgrille™ are recommended.

If the floor is the only option available, then special care should be taken in locating grilles. Areas such as under baseboard heaters will help to temper the air. Also optional inline duct heaters are available for mounting in the supply duct work to add heat if required.

In homes with a forced air furnace, you may want to connect the HRV/ERV to the furnace ductwork (see information below).

Direct Connection to Furnace Ductwork

Should you wish to hard duct the supply air directly into the cold air return of the furnace, remember to check the air flow balance of the HRV/ERV with the furnace fan both "ON" and "OFF" to determine that it does not imbalance the unit more than 10%. Also, it is advisable to include a short length of fabric flex duct or other non-metallic connector in this hard ducted line in order to keep the HRV/ERV separately grounded (electrically) from the furnace. This will avoid a possible shock hazard to service people if a short to ground develops in one of the devices.

Indirect Connection to Ductwork

If permitted by local codes, an indirect connection may be made between the HRV/ERV supply duct and the furnace return plenum. The fresh air from the unit may be directed at a grille installed in the cold air return duct of the furnace. The fresh air supply outlet from the unit should be no closer than 4 inches (100 mm) and no more than 12 inches (300 mm) from the grille.

Stale Air Exhaust System

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 are installed in the bathroom, kitchen, and laundry room. Additional return air ducts from strategic locations (i.e. greenhouse, atrium, swimming pool, sauna, etc.) may be installed. Also, the furnace return duct may be used to exhaust from. In this method, the exhaust air is not ducted back to the HRV/ERV with "dedicated lines" from bathrooms, kitchens, etc. Instead, the exhaust air is drawn out of the cold air return of the forced air furnace. This method has become popular and provides good ventilation when installed in accordance with the instructions. The fur-

nace blower must be running when the unit is operating for this system to be effective.

Dampers and Grilles

The use of balancing dampers and/or adjustable grilles to balance the flow rates into various rooms is recommended. We suggest TECHGRILLE™ air diffusers.

• The TECHGRILLE™ is available in 4", 5", 6" and 8" (100, 125, 150 and 200 mm) sizes.

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

We recommend the use of high mounted wall returns with grilles. The exhaust air duct from the kitchen should never be connected to a range hood. Instead, the exhaust grille should be mounted high on the wall at least 4 feet (1.2 m) horizontally away from the stove. A "flip-up", 6" X 10" (150 X 250 mm) rectangular kitchen grille with removable grease filter is available (Part No. 10-002).

Dampers should be located just prior to the HRV/ERV to balance the stale air exhausted out of the house with a fresh air supply entering the house.

Please Note: 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. All air movement devices have a performance curve. 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/number of fittings used in duct work, duct heater etc.

Page 29

It is necessary to have balanced air flows in an HRV/ERV. The volume of air brought in from the outside must equal the volume of air exhausted by the unit. If the air flows are not properly balanced, then;

• The HRV/ERV may not operate at its maximum efficiency

• A negative or positive air pressure may occur in the house

• The unit may not defrost properly

• Failure to balance HRV/ERV properly may void warranty

Excessive

positive pressure

may drive moist indoor air into the external walls of the building where it may condense (in cold weather) and degrade structural components. May also cause key holes to freeze up.

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/ground contact areas. Excessive negative pressure may also cause the backdrafting of vented combustion equipment.

Read the Application Warning on the front of this manual! Prior to balancing, ensure that:

1. All sealing of the ductwork system has been completed.

2. All of the HRV/ERV's components are in place and functioning

properly.

3. Balancing dampers are fully open.

4. Unit is on HIGH speed.

5. Air flows in branch lines to specific areas of the house should

beadjusted first prior to balancing the unit. A smoke pencil used at the grilles is a good indicator of each branch line's relative air flow.

6. After taking readings of both the stale air to the HRV/ERV duct

and fresh air to the house duct, the duct with the lower CFM ([L/s] velocity) reading should be left alone, while the duct with the higher reading should be dampered back to match the lower reading.

7. Return unit to appropriate fan speed for normal operation

Balancing Procedure

The following is a method of field balancing an HRV/ERV using a Pitot tube, advantageous in situations when flow stations are not installed in the ductwork. Procedure should be performed with the HRV/ERV on high speed.

The first step is to operate all mechanical systems on high speed, which have an influence on the ventilation system, i.e. the HRV/ERV itself and the forced air furnace or air handler if applicable. This will provide the maximum pressure that the HRV/ERV will need to overcome, and allow for a more accurate balance of the unit.

Drill a small hole in the duct (about 3/16"), three feet downstream of any elbows or bends, and one foot upstream of any elbows or bends. These are recommended distances but the actual installation may limit the amount of straight duct.

The Pitot tube should be connected to a magnehelic gauge or other manometer capable of reading from 0 to 0.25 in. (062 Pa) of water, preferably to 3 digits of resolution. The tube coming out of the top of the pitot is connected to the high pressure side of the gauge. The tube coming out of the side of the pitot is connected to the low pressure or reference side of the gauge.

Insert the Pitot tube into the duct; pointing the tip into the airflow. For general balancing it is sufficient to move the pitot tube around in

the duct and take an average or typical reading. Repeat this procedure in the other (supply or return) duct. Determine which duct has the highest airflow (highest reading on the gauge). Then damper that airflow back to match the lower reading from the other duct. The flows should now be balanced. Actual airflow can be determined from the gauge reading. The value read on the gauge is called the velocity pressure. The Pitot tube comes with a chart that will give the air flow velocity based on the velocity pressure indicated by the gauge. This velocity will be in either feet per minute or metres per second. To determine the actual airflow, the velocity is multiplied by the cross sectional area of the duct being measured.

This is an example for determining the airflow in a 6" duct. The Pitot tube reading was 0.025 inches of water. From the chart, this is 640 feet per minute. The 6" duct has a cross sectional area of =

[3.14 x (6"÷12)2]÷4

= 0.2 square feet The airflow is then: 640 ft./min. X 0.2 square feet = 128 cfm For your convenience, the cross sectional area of some common

round duct is listed below:

DUCT DIAM. (inches) CROSS SECTION AREA (sq. ft.)

5 0.14 6 0.20 7 0.27

The accuracy of the air flow reading will be affected by how close to any elbows or bends the readings are taken. Accuracy can be increased by taking an average of multiple readings as outlined in the literature supplied with the Pitot tube.

Installations where the HRV is ducted directly to the return of a furnace 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.

Balancing Collar Instructions

Page 31

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 dish-

washer)

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) mount the left or right side flange of the core 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

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.

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 may occur periodically after that over 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 inline with the fan assembly

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

(a) through the large opening of the fan

assembly and then

(b) through the smaller opening 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.

every year. You may wish to contact a Heating/ Ventilation company to do this.

6. 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.

7. Cleaning the Fans

Fans may accumulate dirt causing an imbalance and/or excessive vibration of the ERV. A reduction in the air flow may also occur. In new construction this may result within the first year due to heavy dust and may occur periodically after that over time depending on the outdoor conditions.

• unplug the ERV 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 inline with the fan assembly

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

(a) through the large opening of the fan

assembly and then

(b) through the smaller opening 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.

Maintenance Routine for ERV (for HRV, see previous page)

SYMPTOM CAUSE SOLUTION

Poor Air Flows

Supply air feels cold

Dehumidistat is not Operating

Humidity Levels are too High Condensation is appearing on the windows

Humidity Levels are too Low

HRV/ERV and / or Ducts Frosting up

Condensation or Ice Build Up in Insulated Duct to the Outside

Water in the bottom of the HRV/ERV

• 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/ERV

• improper speed control setting

• HRV/ERV airflow improperly balanced

• poor location of supply grilles, the airflow may irritate the occupant

• outdoor temperature extremely cold

• improper low voltage connection

• external low voltage is shortened out by a staple or nail

• check dehumidistat setting it may be on OFF

• dehumidistat is set too high

• HRV/ERV is undersized to handle a hot tub, indoor pool, etc.

• lifestyle of the occupants

• moisture coming into the home from an unvented or unheated crawl space

• moisture is remaining in the washroom and kitchen areas

• condensation seems to form in the spring and fall

• HRV/ERV is set at too low a speed

• dehumidistat control set too low

• blower speed of HRV/ERV is too high

• lifestyle of occupants

• HRV/ERV air flows may be improperly balanced

• HRV/ERV air flows are improperly balanced

• malfunction of the HRV/ERV defrost system

• incomplete vapour barrier around insulated duct

• a hole or tear in outer duct covering

• drain pans plugged

• improper connection of HRV/ERVs drain lines

• HRV/ERV is not level

• drain lines are obstructed

• HRV/ERV heat exchange core is not properly installed

• clean exterior hoods or vents

• remove and clean filter

• remove and clean core

• check and open grilles

• open and adjust dampers

• have electrician check supply voltage at house

• check duct installation

• increase the speed of the HRV/ERV

• have contractor balance HRV/ERV

• locate the grilles high on the walls or under the baseboards, install ceiling mounted diffuser or grilles so as not to directly spill the supply air on the occupant (eg. over a sofa)

• turn down the HRV/ERV supply speed. A small duct heater (1kw) could be used to temper the supply air

• placement of furniture or closed doors is restricting the

movement of air in the home

• if supply air is ducted into furnace return, the furnace fan may need to run continuously to distribute ventilation air comfortably

• check that the correct terminals have been used

• check external wiring for a short

• set the dehumidistat at the desired setting

• set dehumidistat lower

• cover pools, hot tubs when they are not in use

• avoid hanging clothes to dry, storing wood and venting clothes

dryer inside. Heating wood may have to be moved outside

• vent crawl space and place a vapour barrier on the floor of the crawl space

• ducts from the washroom should be sized to remove moist air as effectively as possible, use of a bathroom fan for short periods will remove additional moisture

• on humid days, as the seasons change, some condensation may appear but the homes air quality will remain high with some HRV/ERV use

• increase speed of the HRV/ERV

• set dehumidistat higher

• decrease HRV/ERV blower speed

• humidity may have to be added through the use of humidifiers

• have a contractor balance HRV/ERV airflows

• Note: minimal frost build-up is expected on cores before unit initiates defrost cycle functions

• have HVAC contractor balance the HRV/ERV

• ensure damper defrost is operating during self-test

• tape and seal all joints

• tape any holes or tears made in the outer duct covering

• ensure that the vapour barrier is completely sealed

• ensure O-Ring on drain nozzle sits properly

• look for kinks in line

• check water drain connections

• make sure water drains properly from pan
