IMPORTANT - PLEASE READ THIS MANUAL BEFORE INSTALLING UNIT

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 or Energy Recovery Ventilators 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 (i.e. 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!!!

Your ventilation system should be installed in conformance with the appropriate provincial or state requirements or in the absence of such requirements with the current edition of the National Building Code, and / or ASHRAE’s “ Good Engineering Practices”.

Sizing (Example) for maximum airflow normally required.

HRVs are typically sized to ventilate the whole house at a minimum of 0.35 air changes per hour. To calculate, simply take the square footage of the house (including basement) and multiply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by 0.35.

Example:

Introducing the NEW Heat Recovery Ventilators (HRV). As with previous designs, incoming fresh outdoor air is filtered before it is heated by the stale outgoing air through a aluminum heat recovery core. The HRV then distributes the preheated fresh filtered air throughout the home by direct ductwork installed specifically for the HRV or through the ductwork of a forced-air system.

SPECIFICATIONS

CASE 22 gauge galvanized steel on the HRV-200D & 24 gauge galvanized steel on the HRV 150D. Baked powder coated paint. Insulated with 1" (25 mm) high density polystyrene foam to prevent condensation and meet the requirements of the Underwriters Laboratories 94HF.

MOTORS Two (2) German-manufactured, factory-balanced ebm™ motors with backward curved blades. Motors come with permanently lubricated sealed bearings guarantee long life and maintenance-free operation. Seven (7) year limited warranty.*

CORE Aluminum heat recovery core configured for an efficient cross-flow ventilation. Core is 9" x 9" (229 x 229 mm) with a 15" (380 mm) depth HRV 150D or 12" x 12" (305 x 305 mm) with a 15" (380 mm) depth HRV 200D. Cores are manufactured to withstand extreme temperature variations.

FILTERS Two (2) Washable Electrostatic Panel Type Air Filters, HRV 150D is 8.5" (216mm) x 15" (380mm) x 0.125" (3mm), HRV 200D is 11.75" (298mm) x 15" (380mm) x 0.125" (3mm).

CONTROLS External three (3) position (Low/Stand By/Medium) rocker switch that will offer continuous ventilation. We offer a variety of external controls. (see optional controls)

DEFROST A preset 5 minute defrost sequence is activated at an outdoor air temperature of 23˚F (-5˚C) and lower.

During the defrost sequence, its mechanism uses a motorized damper to temporarily block the incoming fresh air stream allowing the warm air from the home to circulate through the HRV. The exhaust blower shuts down & the supply blower switches into high speed to maximize the effectiveness of the defrost strategy.

The unit then returns to normal operation for 25 minutes, and continues cycle.

SERVICEABILITY Core, filters, motors and drain pan can be easily serviced through latched access door. Core conveniently slides out with ease on an improved railing system. Electrical box, placed on the outside of the unit, can also be easily accessed.

* For details concerning warranties, please visit your local dealer.

Introducing the NEW Heat Recovery Ventilators (HRV). As with previous designs, incoming fresh outdoor air is filtered before it is heated by the stale outgoing air through a aluminum heat recovery core. The HRV then distributes the preheated fresh filtered air throughout the home by direct ductwork installed specifically for the HRV or through the ductwork of a forced-air system.

SPECIFICATIONS

CASE 22 gauge galvanized steel on the HRV-200 & 24 gauge galvanized steel on the HRV-150. Baked powder coated paint. Insulated with 1" (25 mm) high density polystyrene foam to prevent condensation and meet the requirements of the Underwriters Laboratories 94HF.

MOTORS Two (2) German-manufactured, factory-balanced ebm™ motors with backward curved blades. Motors come with permanently lubricated sealed bearings guarantee long life and maintenance-free operation. Seven (7) year limited limited warranty.*

CORE Aluminum heat recovery core configured for an efficient cross-flow ventilation. Core is 9" x 9" (229 x 229 mm) with a 15" (380 mm) depth HRV-150 or 12" x 12" (305 x 305 mm) with a 15" (380 mm) depth HRV-200. Cores are manufactured to withstand extreme temperature variations.

FILTERS Two (2) Washable Electrostatic Panel Type Air Filters, HRV-150 is 8.5" (216mm) x 15" (380mm) x 0.125" (3mm), HRV-200 is 11.75" (298mm) x 15" (380mm) x 0.125" (3mm).

CONTROLS External three (3) position (Low/Stand By/Medium) rocker switch that will offer continuous ventilation. We offer a variety of external controls. (see optional controls)

DEFROST A preset 5 minute defrost sequence is activated at an outdoor air temperature of 23˚F (-5˚C) and lower.

During the defrost sequence, the supply blower shuts down & the exhaust blower switches into high speed to maximize the effectiveness of the defrost strategy.

The unit then returns to normal operation for 25 minutes, and continues cycle.

SERVICEABILITY Core, filters, motors and drain pan can be easily serviced through latched access door. Core conveniently slides out with ease on an improved railing system. Electrical box, placed on the outside of the unit, can also be easily accessed.

Introducing the NEW Heat Recovery Ventilators (HRV). As with previous designs, incoming fresh outdoor air is filtered before it is heated by the stale outgoing air. The HRV then distributes the preheated fresh filtered air throughout the home by direct ductwork installed specifically for the HRV or through the ductwork of a forced-air system.

SPECIFICATIONS

CASE 22 gauge galvanized steel. Baked powder coated paint. Insulated with 1" (25 mm) high density polystyrene foam to prevent condensation and meet the requirements of the Underwriters Laboratories 94HF.

MOTORS Two (2) German-manufactured, factory-balanced ebm™ motors with backward curved blades. Motors come with permanently lubricated sealed bearings guarantee long life and maintenance-free operation. Seven (7) year limited warranty.*

CORES Two (2) aluminum heat recovery cores configured for an efficient cross-flow ventilation. Core is 12" x 12" (305 x 305 mm) with a 15" (380 mm) depth. Cores are manufactured to withstand extreme temperature variations.

FILTERS Two (2) synthetic high quality filters for better indoor air quality and clean air.

CONTROLS External three (3) position (Low/Stand By/Medium) rocker switch that will offer continuous ventilation. We offer a variety of external controls. (see optional controls)

DEFROST A preset 5 minute defrost sequence is activated at an outdoor air temperature of 23˚F (-5˚C) and lower.

During the HRV-300 defrost sequence, its mechanism uses a motorized damper to temporarily block the incoming fresh air stream allowing the warm air from the home to circulate through the HRV. The exhaust blower shuts down & the supply blower switches into high speed to maximize the effectiveness of the defrost strategy.

The unit then returns to normal operation for 25 minutes, and continues cycle.

SERVICEABILITY Core, filters, motors and drain pan can be easily serviced through latched access door.

OPERATION

A Heat Recovery Ventilator (HRV) is designed to bring 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 HRV will help in cooling the incoming fresh air with the stale air that is being exhausted.

Our HRV’s are designed to run continuous or on intermittent, giving the homeowner complete control over their air quality. Continuous low speed ventilation is recommended, which will help eliminate carbon dioxide, voc’s and other gases as well as freshen up the home. Intermittent high speed ventilation can be obtained through a variety of optional remote controls found in this manual (page 13 ). Below are some examples of seasonal operation of an HRV.

Winter:

Humidity control is very important during the winter months. This is when problems will be most apparent since condensation on the windows will often occur. The colder the outside temperature, the greater the risk of condensation in the home. The average relative humidity should be maintained between (30-60) to avoid conden-

sation. Low speed continuous ventilation with high speed override is recommended.

Summer:

The air is sometimes hot and humid. To stop the warm humid air from entering, set the dehumidistat at its highest level. If the digital control is installed, the air exchanger can be set to cycle the unit on and off as desired from that wall control. However, continuous ventilation is recommended.

Spring:

Temperatures are more moderate and become warmer each day. To keep the humidity and temperature uniform, set the dehumidistat higher (if installed). You may also switch the HRV to standby mode if desired.

Fall:

Rain and rapid temperature changes make it difficult to control the internal humidity level and may result in condensation on the windows. A remote dehumidistat may help give greater control over the inside environment.

The entire line of Heat Recovery comes equipped with our new electronic uni-control board which offers a wide variety of features making it the ultimate ventilation control system. Our engineers have used the latest technology to provide solid, trouble free operation under any conditions.

The uni-control board offers stand alone operating capabilities as well as an exclusive 2 wire communication to most external controls. The troublefree optional controls include: two different rotary dial dehumidistats, an air quality sensor (3 wire communication required), a 15 minute remote push-button timer, as well as the most sophisticated line of remote wall mounted controls, the digital control.

An on-board diagnostic LED helps find problems quickly and efficiently. For example the LED can be used to signal a broken or shorted electronic wall control wire. Electronic air temperature probe gives this board accurate readings in order to minimize unnecessary defrost operation, and the on-board jumpers provide the user with the option of adjusting defrost time and sequence to optimize performance under abnormal conditions. The defrost operation is automatic and is usually never adjusted.

1. Continuous / Ventilation Mode

In this mode of operation both fans are operating and exchanging air with

the outside. The heat recovery venti-

lator (HRV) constantly exchanges the air at the rate you select, either at low or medium speed, and switches to high speed when activated by an optional remote control. The "Low" and "Med" fan speed selection will cause the unit to operate in continuous exchange mode at an exchange rate of 35% and 50% maximum airflow rating respectively. Continuous mode is recommended, since pollutants are slowly but constantly being generated in your house.

The automatic defrost cycle consists of a damper defrost which allows air

to recirculate throughout the unit & home. When the supply air stream

temperature goes below -5°C (23°F), the exhaust motor shuts down, the supply motor goes to high speed, and a damper closes the supply, opening a 5th collar. The ambient air is then recirculated through the unit & home for a period of 5 minutes. The unit will then resume normal operation for a time period of 25 minutes. This damper defrost cycle continues until the supply air stream rises above 0°C (32°F). The recirculation feature can be obtained with the use of an optional digital control.

The automatic defrost cycle con-

sists of a fan shutdown. When the

supply air stream temperature goes below -5°C (23°F), the sup-

ply motor shuts down and the exhaust motor goes into high speed. Ambient air is passed through the unit for a period of 5 minutes. The supply motor will then re-start and run at the preset speed. The exhaust motor will also slow down to the preset speed, and the unit will operate in the run cycle for 25 minutes. This fan shutdown defrost cycle continues until the supply air stream rises above 0°C (32°F).

Dehumidistat - MD-2W - The wall mount dehumidistat monitors the humidity level in the area it is installed. When the humidity level rises above the desired set-point, the HRV will activate to high speed/override mode. Once the humidity level returns to desired condition, the unit will return to the normal mode.

Air Quality Sensor - AQS - The wall mount Air Quality Sensor (AQS) monitors indoor air quality and activates the override mode when carbon monoxide, formaldehyde, benzene, volatile organic compounds and other pollutants are detected. The unit will then return to normal mode once the air pollutants are reduced to a pre-determined lower level.

* This control is not a warning device.

15-min Timer - RT-15M - The 15-minute remote timer is typically installed in areas where contaminated such as moisture and odors, are produced. Simply push the button and the HRV will activate to high speed for 15 minutes. Up to 5 electronic timers can be installed throughout the building at a distance of up to 500 feet (152 meters) from the HRV.

PRACTICAL

TIPS

NOTE:

When an digital control is installed, the rocker switch located on the right hand side of the HRV will be automatically deactivated giving the user complete control from wherever he/she wishes to mount the control pad.

NOTE:

The override speed cannot be set at a fan speed lower or equal to the normal operating fan speed. For example, if the unit is normally operating at a medium fan speed, the override fan speed will be automatically set to high.

NOTE:

DMFC-REC model, changing the override speed will change default override speed for other external controls.

EXAMPLES:

If on the DMFC-REC control, you have set the override control at medium, and you start an external remote control, the unit will run at medium speed for 15 min.

INSTALLATION

PRACTICAL TIPS

Install the unit close to the outside wall on which the supply and exhaust hoods will be mounted.

Have a nearby power supply 120 Volts, 60Hz.

Have the possibility of mounting the unit to supporting beams.

Mount the unit as level as possible in order to allow proper condensate drainage.

Have access to

a water drain for the condensate of the unit during defrost.

Have a certain amount of heat around the unit (attic installation is not recommended).

Minimize any noise level that would be created by the unit in the living area.

Have access for future maintenance.

LOCATION

The HRV must be located in a heated space where it will be possible to conveniently service the unit. Typically the HRV 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:

-the complexity of work to install

-freezing conditions in the attic

-difficulty of access for service and cleaning

Connecting appliances to the HRV It is not recommended, including:

-clothes dryer

-range top

-stovetop fan

-central vacuum system

These appliance may cause lint, dust or grease to collect in the HRV , damaging the unit. NOTE: Connecting any of these type of appliances to the HRV will invalidate your warranty

Installing Drain Line

Through normal operation and during its defrost mode, the HRV may produce some condensation. This water should flow into a nearby drain, or be taken away by a condensate pump. The HRV and all condensate lines must be installed in a space where the temperature is maintained above the freezing point. A “P” trap should be made in the drain line. This will prevent odors from being drawn back up into the unit.

INSTALLING DUCTS GOING TO / FROM OUTSIDE

PRACTICAL

TIPS

•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 least 4' - 6’ (2m) from the exhaust weatherhood

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

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

At least 18” (457mm) above the ground, or above the depth of expected snow accumulation

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

Do not locate in a garage, attic or crawl space

A well designed and installed ducting system will allow the HRV to operate at its maximum efficiency. Always try to keep duct runs as short and straight as possible.

See Installation Diagrams for installation examples.

INSTALLING THE DUCTING

TO THE WEATHERHOODS

The inner liner of the flexible insulated duct must be clamped to the sleeve of the weatherhoods (as close to the outside as possible) and to the appropriate port on the HRV. The insulation should remain full and not be squished. The outer liner, which acts as a vapor barrier must be completely sealed to outer wall and the HRV using tape and or caulking. A good bead of high quality caulking (preferably acoustical sealant) will seal the inner flexible duct to both the HRV 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 should be stretched tightly and be as short as possible. Twisting of folding the duct will severely restrict air flow.

13

INSTALLING DUCTS TO / FROM INSIDE

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 are preferred to 90º elbows. Use “Y” tees instead of 90º elbows whenever possible.

All duct joints must be fastened with screws or duct sealant and wrapped with a quality duct tape to prevent leakage. Aluminum foil duct tape is recommended. Galvanized ducting from the HRV to the living areas in the house is recommended whenever possible, although flexible duct can be used in moderation when necessary.

SUPPLY AIR DUCTING

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.To avoid possible noise transfer through the ductwork system, a short length (approximately 12”, 300 mm) of nonmetallic flexible insulated duct should be connected between the HRV and the supply/exhaust ductwork system.

The main supply and return lines to/from the HRV 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.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 to the furnace ductwork (see information below).

PRACTICAL TIPS

Building Codes and Combustion Appliance Installation Codes do not allow location of return air grilles or any opening such as a “breathing tee” in an enclosed room with spillage susceptible combustion appliances.

The fresh air inlet from the HRV needs to respect a minimum distance from the furnace return drop to ensure proper air mixing and temperature at the furnace core.

See furnace manufacturer for appropriate specifications.

Direct Connection

A direct connection requires that the fan of the furnace runs continuously. It may be inter-linked electrically (low voltage) with the HRV (Accessory Control Contacts) for intermittent demand. Should you wish to hard duct the supply air directly into the cold air return of the furnace, remember to check the airflow balance of the HRV with the furnace fan both “on” and “off” to determine that it does not imbalance the HRV more than 10%. Make sure you respect the 1m minimum distance from the supply air in of the HRV and the furnace (Refer to your local and National Building & Heating Codes for any variations in these notes).

For minimum distance See local building codes and practical tips.

INSTALLING DUCTS TO / FROM INSIDE (CONT'D)

Exhaust Air Ducting

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 (i.e. greenhouse, atrium, swimming pool, sauna, etc.) may be installed. The furnace return duct may be also used to exhaust from. In this method, the exhaust air is not ducted back from bathrooms, kitchens, etc to the HRV with “dedicated lines”. This method has become popular and provides good ventilation when installed in accordance with the instructions. The furnace blower must be running when the HRV is operating for this method to be effective.

PRACTICAL TIPS

For new construction, the rigid ducts are run in the walls.

Choose the location for your Supply and Exhaust grilles. The Supply grilles should be located in every habitable room and the Exhaust Grilles should be located in the wet rooms.

A piece of flexible ducting should be placed between the Supply Air In and Out collar of the HRV and the rigid ducting to absorb any noise or vibrations.

For proper network

of ducting, see TYPES OF

INSTALLATIONS.

Dedicated Installation for Existing Home -

(non forced air heating / cooling system)

1Begin with the duct collar marked “Exhaust Air In”. Slide a short piece (12”) of flexible duct over the duct collar. Using duct tape, tape the flexible duct to the collar. Run the flexible ducting to the main rigid duct trunk line, which connects to the remainder of the ducts going to and from rooms in the house. Repeat the steps for the “Supply Air Out” on the side of the HRV.

2Working from a closet, attic or inside your joist wall, run the length of ducting required for the proper grille location and cut a hole in the drywall. Fasten the mounting collar (optional) to the ducting and fasten the collar to the wall or ceiling with screws.

3The grille airflow can be adjusted by rotating the inside unit. It is recommended that the grilles be completely opened at first and then adjusted later as needed.

The grilles are to be installed on the ceiling or on the wall 6” (152

mm)to 12” (305 mm) from the ceiling.

4 Push the grille into the optional mounting collar or directly into installed elbow.

15

INSTALLATION EXAMPLES

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.

Ducting Fifth Port Units

All HRV(D)’s have a fifth duct port on top of the unit. This duct port is for both defrost and the recirculation mode. A motorized damper installed in the port closes during defrost or recirculation temporarily blocking the incoming fresh air-stream, allowing the warm air from the house to circulate through the HRV. You may wish to duct this port to a common clean air room (living room or dining room) so when recirculation is activated, household odors from the kitchen, bathroom or basement won’t be introduced into the living spaces of the home environment.

RADIANT HEATED HOMES

NOTE:

The recirculation function can be accessed with a optional digital control. It allows air to move gently throughout the home without exchanging air to the outside, until needed.

AIR FLOW BALANCING

CAUTION

If the unit’s airflows are not properly balanced...

-The unit may not operate at it’s maximum efficiency.

-Heat recovery core damage may occur.

-The unit’s use could cause negative or positive pressure in your home causing cold air to enter or other combustible equipment to backdraft.

-The unit may not defrost properly.

PITOT TUBE BALANCING PROCEDURE

PITOT TUBE

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. (0-62 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). Reduce this airflow using either the electronic balancing system (if applicable) or damper. The flows should now be balanced. Actual airflow can be determined from the gauge read-

ing. 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 meters per second. To determine the actual airflow, the velocity is multiplied by the cross sectional areas 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" diameter (D) duct has cross sectional area (A) of

A = 3.14 x (D/24) 2

A = 3.14 x (6/24) 2

A = 0.196 or about 0.2 ft2

The airflow is then: 640 ft/min x 0.2 ft2 = 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.)

50.14

60.20

70.27

80.35

The accuracy of the airflow 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.

Place pitot tube a minimum of 18" from blower elbows.

Note:Ductconnections may vary, depending on model.

Magnehelic

*Pitot tube should be kept at least 12” away from fans elbows and dampers to ensure accurate reading.

*A calibration decal is included to place over electronic balancing system adjustments after it has been balanced.

The balancing procedure consists of measuring the exhaust air leaving the system and the supply air entering the system and ensuring that these two are equal. A deviation of 10% or less is acceptable. In such cases, it is recommended to have a greater amount of exhaust air than supply

20

air as so to increase the supply air’s temperature.

AIR FLOW BALANCING (CONT'D)

AIRFLOW STATION (GRID) METHOD

B

1For this flow measuring station, cut the duct and place the flow measuring station between each station. Make sure that the flow measuring station’s air direction arrow points in the direction of the airflow. Secure the flow measuring station with duct tape.

2Before taking the reading, make sure that the magnehelic gauge is level and at 0. Refer to the flow measuring station’s chart to determine your unit’s airflow velocity.

MAINTENANCE

CAUTION MAKE SURE UNIT IS UNPLUGGED BEFORE ATTEMPTING ANY MAINTENANCE WORK

The following components should also be inspected regularly and well maintained.

PRACTICAL

TIPS

To prevent electrical shock, check that the unit is unplugged before doing any repairs or maintenance.

A yearly inspection is recommended to ensure the efficiency and troublefree use of your system. Run through the system and verify the different operating modes.

The motor - The motors are factory balanced and lubricated for life. They require no maintenance.

The unit - The inside of the unit should be vacuumed yearly. Be careful not to damage any of the mechanical components and electrical connections.

The drain pan and drain line - Units with drain lines should have their line and connection checked regularly.

Outside hoods - The outside hoods need to be checked every season to make sure there are no leaves or insects blocking the airflow. Check regularly that there are no pollutants near the intake hood. Make sure they are clear of any snow accumulation during the winter months.

Filters need to be checked regularly

FILTERS

The filters (2) need to be checked and cleaned every three months or when they appear dirty. Wash in warm sudsy water (mild detergent) or use a soft brush vacuum. The filters should be replaced when they can no longer be cleaned properly.

HEAT RECOVERY CORE

The heat recovery core needs to be checked and cleaned every six months. The core can be cleaned using a mild soap and water. Rinse thoroughly. Handle with care. Hot water and a strong detergent will damage the heat recovery core. It is recommended to clean the core in the summer or when the temperature is mild. Never clean the heat recovery core during winter.

Clean Core and Filters Every 3-6 Months.

Unplugged before doing any repairs or maintenance

a)Open access door.

b)Carefully grip ends of core and pull evenly out ward. 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.

To Install the Clean Core and Filters.

a)First mount the bottom flange of the core guide into the bottom 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 channel approximately 1/4” (6mm).

d)With all four corners in place and the core straight and even, push hard in the center of the core until the core stops on the back of the cabinet.

NOTE: Some products may not be exactly as illustrated in Installation, Operation and Maintenance manual.

TROUBLESHOOTING

Problem

 

Causes

Solutions

 

 

 

 

 

Air is too dry

 

Dehumidistat control is set too low

Increase the desired level of humidity. Change ventilation mode from

 

 

 

 

continuous mode to standby.

 

 

 

 

Balance HRV

 

 

HRV out of balance

 

 

 

 

 

Air is too humid

 

Dehumidistat control is set too high

Reduce the desired level of humidity. Combine this step with use of con-

 

 

 

 

tinuous exchange mode.

 

 

Sudden change in temperature

Wait until outside temperature stabilizes (winter). Heating will also

 

 

 

 

improve situation.

 

 

Storing too much wood for heating

Store a majority of your wood outside. Even dried, a cord of wood con-

 

 

 

 

tains more than 20 gallons of water.

 

 

Dryer vent exhaust is inside home

Arrange outside vent for dryer.

 

 

Poor air circulating near windows

Open curtains or blinds. Bay or bow windows may require mechanical

 

 

 

 

method.

Balance HRV

 

 

Well sealed basement door is closed

Open the door or install a grill on the door.
