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.

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.

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.

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

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.

Commercial and Institutional Requirements

For outdoor air requirements, ASHRAE has produced the Ventilation Standard 62-1989 that
is used to determine acceptable ventilation rates. This standard is referenced directly or
used as “Good Engineering Practice” in most Code documents or design criteria.

Location for Mounting

The Ductwork System

The HRV/ERV must be located in a conditioned
space where the surrounding air temperature
does not fall below 60˚F (16˚C). The unit must be
mounted level (horizontal). The warranty will be
void if these conditions are not met.

Typically the HRV/ERV is positioned close to
an outside wall or the roof to simplify the
connections and keep the length of insulated
ducting required for the fresh air intake to a
minimum.

A minimum clearance of 36 inches (90 cm) in
front of the HRV/ERV is recommended to service
the ventilator. The HRV/ERV may be mounted on
an equipment platform providing the drain hoses
are clear and there is sufficient space to open the
doors for servicing.

Install the drain pans in the bottom of the
HRV/ERV so the drain (not on all models)
connections protrude through the holes provided.
Use drain hoses with hose clamps to connect the
drain pan outlets to a floor drain or standpipe.
Make sure the drain line slopes down to the
outlet. If this is not possible a condensate pump
will be required for positive removal of the water.
Protect the drain line from freezing.

A properly designed ducting system will allow the
HRV/ERV to operate at its maximum efficiency.
(Air flow will be restricted by undersized ducting,
use of too many elbows, tees, bends, etc.).
Always try to keep duct runs as short and
straight as possible.

NOTE: Fully insulated ducting with an integral

vapour barrier must be used on all runs
passing through unheated areas in order
to avoid condensation problems and
energy losses from the air steams.

All joints must be airtight, sealed and impervious
to moisture. See specification sheets for each
unit for exact duct sizes and location.

To minimize pressure drop and noise, galvanized
metal ducts, properly sized, are recommended.
Keep ducting as short as possible and use a
minimum of elbows and tees. Connecting sections
and shorter runs may be flexible ducting one size
larger than the metal equivalent. Use flexible duct
connectors at the
transmission.

All duct joints must be secured with screws,
rivets or duct sealant and sealed with aluminum
duct tape to prevent leakage.

Outside Weatherhoods

The weatherhoods must have built-in “bird” screen with
1/4 in (63.5 mm) minimum mesh to prevent birds and
rodents from entering into the ductwork. Do not
smaller mesh as it will be very susceptible to plugging
up. Gravity dampers at the vents must not be used as
they will restrict air flow and often “seize up”. The
preferred location of the outside weatherhoods is:

• no less than 10 ft. (3 m) apart from each other

• at least 18 in ( 46 cm) above snow line or
ground level

• away from sources of contaminants, such as

automobile exhaust fumes, gas meters,
garbage cans, containers, etc.

• not exposed to prevailing winds, whenever
reasonable possible

The outside perimeter of the weatherhood must be
caulked to prevent leakage into the building.

The design and size of the weatherhoods or louvres
chosen by the installer must allow for adequate free
area. Water and debris penetration of the system is
minimized when the airflow does not exceed 1000 FPM
(5.08 m/s) free area velocity.

use

Ducting from the Weatherhoods

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 tape.

Stale Air Return System

The stale air return system is used to draw air from the
points in the building where the worst air quality
problems occur. Balancing dampers and/or adjustable
grilles are recommended on all return air lines which
are used during installation to help balance the “draw”
from different areas of the building.

Alternately, the stale air may be drawn directly from
the return air duct. When this system is used, the air
handler’s blower must constantly operate. The exhaust
takeoff connection must be at least a 3 ft (1 m) from
a directly connected HRV/ERV supply duct if both are
connected to the same duct run. Static pressure of the
air handlers return system should be noted and
compensated for if, it is apparent that the static
pressure of the return in the air handler will exceed
.1 to .15” W.C.

A damper located just prior to the HRV/ERV is
required to balance the stale air exhausted with the
fresh air supply entering the building.

Galvanized sheet metal ducting with sufficient cross
section with an integral single piece vapour barrier should
be used to connect the HRV/ERV to the weatherhoods.

All ducting must meet UL Class 1 requirements.

A minimum R value of insulation should be equal to
4 (RSI 0.75)

A good bead of high quality caulking (preferably acousti­cal sealant) and taping with a high quality aluminum foil
tape is recommended to seal the duct to both the
HRV/ERV and the weatherhood.

Warmside Ducting - General

Ducting from the HRV/ERV to the different areas in the
building should be galvanized metal whenever possible.

To minimize airflow losses in the ductwork system, all
ducts should be as short as possible and with as few
bends or elbows as possible. 45° elbows are preferred
to 90° elbows. Use “Wye” (Y) fittings instead of “Tees”
(T) whenever possible.

Return air suction points should be located on the
opposite side of the room from the fresh air inlet. The
inlets may be located in the ceiling or high on the walls
and fitted with inlet grilles.

Many commercial activities produce air contaminants in
the form of dusts, fumes, mists, vapours and gases.
Contaminants should be controlled at the source so that
they are not dispersed through the building nor allowed
to increase to toxic concentration levels. The ventilator
allows for economical operation of the HVAC system
while effectively removing contaminants from the space.
In designing the exhaust portion of the system
the exhaust grilles are placed so as to remove the
contaminants while not allowing them to enter the
breathing zone of the occupants.

For contaminants that are lighter than air, grilles should
be located high on the wall. If contaminants are heavier
than air, a lower placement of the grilles will be
required. Information on a contaminants specific gravity
and toxicity should be available from chemical data
sheets.

14

Fresh Air Supply System

The Integrated HVAC System

The fresh air supply ductwork from the HRV/ERV may
be directly connected to the return air duct of the
forced air system. Check the air flow balance of the
HRV/ERV with the air handler blower both “ON” and
“OFF” to determine that it does not imbalance the
HRV/ERV more than 10%. Also, it is advisable to
include a short length of flex duct or other non-metallic
connector in this hard ducted line in order to keep
the HRV/ERV acoustically isolated and separately
grounded (electrically) from the air handler. This will
avoid a possible shock hazard to service people if a
short to ground develops in one of the devices.

It may be necessary to install a separate fresh air supply
ductwork system if the heating is other than forced air.

When installing an HRV/ERV, the designer and
installer should be aware of local codes that may
require smoke detectors and/or firestats in the HVAC
or HRV/ERV ductwork.

Because an HRV/ERV is designed to bring fresh air
into the building, structures may require supply voltage
interrupt when smoke or flame sensors are triggered,
or when a central fire alarm system is activated.

Supply air grilles may be ceiling or high wall mounted.
Avoid locating incoming fresh air grilles that could
cause a direct draft on the occupants as the incoming
air may be below room temperature. A reheat duct
heater can be installed to improve occupant comfort.

The use of balancing dampers or adjustable grilles to
balance the flow rates into various rooms is
recommended.

The use of balancing dampers or adjustable grilles
as supply air diffusers and air exhaust covers are
recommended. TECHGRILLES™ are round, efficient,
sound absorbing devices available in 4”, 5”, 6” and 8”
(100, 125, 150, and 200 mm) models.

Figure A and B

The HRV/ERV has become an integral component of
the HVAC system. Figure A shows an HRV/ERV unit
providing fresh air directly to the return air plenum of a
rooftop heat/cool unit.

In the balanced airflow system, the HRV/ERV exhaust
removes stale room air (eg. from lunch room, storage
or copy area) and returns to the space an equal
amount of fresh outdoor air, making the use of an
economizer obsolete in conjunction with an HRV/ERV.

Many buildings have ceiling return air plenum as
in Figure B. Fresh air from the HRV/ERV can be
introduced directly into the ceiling space but this
should occur near the air handler’s intake.

By operating the HRV/ERV on a 24 hour/7 day battery
backed timer, the unit can be set to operate only when
occupancy or indoor conditions require the air
exchange.

In installations where it is satisfactory to provide
general exhaust from the space, the air to be
exhausted may be taken directly from the return air
plenum to the HRV/ERV as it is drawn back to the air
handler. Fresh air supplied by the HRV/ERV is then
introduced directly into the return air plenum but at a
location closer to the air handler. The air handler
would have a constant running blower to effectively
distribute the fresh air and remove the stale air.
Balancing dampers would be located in both the
HRV/ERV supply and exhaust ducts between the
return air plenum and the HRV/ERV.

NOTE: At no time should the air handler T.E.S.P. on
the return duct exceed that of the HRV/ERV .

is activated. A motor driven damper door mechanism
opens the defrost port and at the same time closes off
the supply air from outside. After approximately 3
minutes, the damper operates in the opposite direction
to close off the defrost port and reopen the fresh air at
the supply port. The 27.5 minute wait time and 3

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.

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.

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

PITOT TUBE AIR FLOW BALANCING

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

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

degrade structural components. May also cause key holes to freeze up.

positive pressure may drive moist indoor air into the external

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.

Excessive

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

2.

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

negative pressure may have several undesirable effects.

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 =
The airflow is then:

640 ft./min.
For your convenience, the cross sectional area of some common

round duct is listed below:

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

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

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.

SERVICE/MAINTENANCE

Servicing your HRV/ERV on a regular schedule will
result in optimum operating efficiencies and
prolonged life of the equipment.

Due to numerous applications in which this
equipment can be installed, it is difficult to predict
servicing intervals. In certain situations where there
is heavy smoke, servicing the equipment every one ­two months may be needed; whereas ventilating a
meeting room for example for carbon dioxide may
only need service every six months to a year.

MOTOR

Access to the motor is through the front service
doors. Note heat exchanger core can be removed to
provide more room. See CORE in this section.

The motor is a permanent split capacitor type (PSC)
which uses a sleeve mechanism to steady the shaft.
There is an oil wick beside the sleeve which supplies
oil to it on a continuous basis.

If the motor does not have oil tubes, no maintenance
is required.

Access to the wick is through oil tubes, (two per
motor) located in the motor case itself. These oil
tubes are either capped with yellow plugs, (which
need to be removed for oiling) or have clear tubes
protruding from them.

In either case an oiling device such as an “Oil
Telespout” filled with 20 S.A.E. non-detergent electric
motor oil should be used to put oil inside the tubes. A
couple of drops of oil once a year will do.

DO NOT OVER OIL!

HRV CORE (HRV only)

The heat exchange core is accessible through the
front service door. Special care and attention should
be given to this component as the edges may be

sharp, and the core itself susceptible to damage
if dropped.

When removing the core, the location it is removed
from should be noted.

The core is removed by carefully pulling the core
outward from the unit, sliding it evenly along its “H
channel” supports found in each corner of the core.
Note the core may have some resistance when
sliding out. Avoid tilting the core as this will result in
its edges catching the H channel and temporarily
preventing its removal.

In most cases, washing the core in a mild
detergent and warm water will be all that
is needed to completely clean them. Do not use
harsh chemicals as this may cause corrosion in the
HRV. The time between core service will depend
on the application the HRV has been installed in.
It can be as often as one - two months or at the very
least, cleaned every six months. When reinstalling

the core you must note foam location and drip
edge location for proper core placement.

See diagram below.

ERV CORE (ERV only)

Remove core and vacuum or use low pressurized
clean core. Do not wash or submerse in water.

With the core in its proper position, place the
bottom flange, (approximately 1/4”) into its H channel
support, then place the left side, the right side and
finally the top flange into place in the same fashion.
Once all four corners are in place, push the core
evenly into the cabinet until it reaches the back. Be
sure the drip edges are overlapping the drip trays.

Note the core will protrude slightly out from the front
of the cabinet, this is so the access door, when
closed, ensures a tight fit.

FILTERS

Open front service door to access the filters
located in both supply and exhaust air streams.
Note to remove and install filters, it may be easier
to first remove the core(s). See CORE.

The filters are designed to stop large particles
from entering in the core. The filters are fastened
in place by a metal spring rod. To remove filters
from core(s) simply pull the rod from one end,
outward until free from core lip, and remove.

Only use warm water with a mild detergent to
wash the filters. Do not use harsh chemicals.

The time between filter service will depend on the
application the HRV/ERV has been installed in. It
can be as often as one - two months or at the
very least, cleaned every six months.

CONDENSATE DRAINS

The condensate drains consist of two drain pans
which may collect water after the HRV/ERV
initiates a defrost cycle, and a drain line to
remove the condensate.

Maintenance on this portion of the system should
be done as often as possible and should not
exceed six months. Note bacterial growth in
standing water is a major concern to healthy
indoor air quality, and should be avoided whenever
possible.

To clean these components, open the front
service door and flush the pans with water.
Ensure that the pans drain completely and in a
reasonable amount of time. Note if the water
does not drain right away, check for blockage in
the drain line, also check that the drain line has a
good slope to it. (1/8 - 1/4” per foot)

DUCT WORK

It is a good idea to inspect ducting, outside
weather hoods (wall caps), and grilles for blockage
and dirt buildup, at least every six months.

Outside weather hoods should be protected by a
rodent screen which can plug up with debris.
Also, it is a good idea to visually confirm that
the fresh air supply is free from any sources of
contamination, such as other vented combustion
equipment added after the fact.

DAMPER MOTOR

The damper motor, (if applicable) is a self
contained motor and does not require service.
The damper door attached to the motor could use
a little lithium grease on the shaft opposite the
motor, where it enters its holder, once every
two - three years.

General Maintenance

As a final step in a routine maintenance
schedule, it is a good idea to confirm operation of
the system, checking speed control functions and
remote control operation, if applicable.

Wipe the inside of the cabinet to remove dust and
cob webs as needed.

It is a good idea to keep a service/maintenance
log of the unit.

The drain line itself should have a “P” trap in it
below the HRV/ERV which is to be filled with
water to prevent odours or gases from entering
back into the unit. When flushing out the drain
pans, this too will be flushed out, and the water
that was there will be replaced with clean water.
