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) or 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!!!

INTRODUCTION
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).
WARRANTY
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.

ERV Questions & Answers
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. This dramatic advance makes more energy
available for recovery as the unit spends less time in
defrost mode. By optimizing the defrost cycle, the
HRV/ERV combines money saving performance with a
well designed and reliable control system.
FUNCTION & CONTROL
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 40% 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

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 30-45%.
The dehumidistat will overide 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.

INSTALLATION
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 HRVERV
.

INSTALLING AIR DUCTS
A well designed and installed ducting system will allow the
HRV/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 weatherhoods 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.

SUPPLY AIR DUCTING
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 furnace 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.
25
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 be
adjusted 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 duct-
work. 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 con-
nected to the low pressure or reference
side of the gauge.
Insert the Pitot tube into the duct; point-
ing 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 high-
est 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.

BALANCING COLLAR INSTRUCTIONS
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.
27
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) 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.

Technical Bulletin
When using the ControlAir 15 relay contacts to initiate blower operation on a
furnace, certain thermostats will initiate the outdoor cooling condenser when
R and G are closed.
Use this wiring configuration to stop the ControlAir15 relay contacts from initializing
the condenser unit. This problem can occur at the thermostat because the Yterminal
is connected to the Gterminal internal to the stat. When Rand Gare closed at the fur-
nace (by dehumidistat or relay) 24 Volts is sent to Gat thermostat. 24 Volts is then
sent through Ywhich will initiate outdoor condenser.
