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
operating at a higher static. After installation, the
compatibility of the two pieces of equipment must
be confirmed by measuring the airflows of the
Heat Recovery Ventilator (HRV) by using the
balancing procedure found in this manual.
It is always important to assess how the
operation of any HRV 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!
Application
Heat Recovery Ventilators (HRV) are designed to provide
fresh air while exhausting an equal amount of stale air.
General
The HRV is equipped with an aluminum core. The
device uses the stale air that is being exhausted to
condition the fresh air as it is being brought in.
These instructions are intended as a general guide and
do not supersede local codes in any way. Consult
authorities who have jurisdiction before installation.
Do not apply electrical power to the unit
until installation has been fully completed
(including low voltage control wiring).

Roof Curb Assembly Instructions
Frame Assembly
1. Take one end piece (locking tabs) and one side
piece (slots). Stand both pieces vertically on the
floor or roof. See Figure 1.
2. Raise slightly the corner of the end piece
(locking tabs) and mate with side piece (slots),
ensuring that lower locking tab with leading edge
is through slot opening. See Figure 2.
3. Push down on top edge of end piece. Ensure
that all 3 of the locking tabs are feeding into
each corresponding slot. Once both pieces are
flush, the process is complete. See Figure 3.
4. Drive one spike provided into wood nailer strips
at each corner. See Figure 3.
FrameApplicationandLocation
This roof mounting frame provides necessary
support when the unit is installed. The frame can be
installed directly on deck having adequate structural
strength or on roof supports under deck.
SecuringtheFrame
To ensure proper mating with unit, it is critical
that mounting frame be squared to the roof, as
follows:
1. With frame situated level in desired location on
roof trusses, tack weld one corner of frame.
2. Measure frame diagonally from one corner to
the opposite corner. Repeat with the remaining
two corners. These dimensions must be equal for
the frame to be square.
3. It is extremely important to sight frame from all
corners to ensure that the frame is not twisted
across top side. Shim frame under any low sides.
4. After frame has been squared, straightened and
shimmed, weld or attach frame securely to roof.

Ducting - General
Drains
Connect the drain pans in the bottom of the HRV to a
drain line fastened to the holes provided. Create a "P"
trap to prevent odors from being drawn through. Make
sure the drain line slopes down to drain properly and if
this is not possible a condensate pump will be required
for removal of the water. Note that stagnant water is a
leading cause of indoor air quality problems; confirm
drainage after installation by pouring water into trays.
Drain line must be installed where it will not freeze.
TheDuctworkSystem
A well designed ducting system will allow the HRV to
operate at its maximum efficiency. Avoid the use of
under-sized ducting and sharp radius bends and tees
which can significantly increase the system pressure
drop and reduce the air flows.
NOTE: Fully insulated ducting with an integral vapor
barrier must be used on all runs passing through
unheated areas in order to avoid condensation problems
and energy losses from the air streams.
* ConsultlocalCodes
To minimize pressure drop and noise, galvanized metal
ducts sized for 725 fpm (3.68 m/s) (maximum velocity)
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 duct. Use flexible duct connectors at the
HRV to avoid noise transmission.
All duct joints must be secured with screws, rivets or
duct sealant and sealed with aluminum duct tape to
prevent leakage.
OutsideWeatherhoods
The 1500E-ECM is shipped with 2 weatherhoods inside
the cabinet which attach to the outer ends of the
cabinet using bolts provided. The 1500I-ECM requires
hoods to be built elsewhere and provided by the
contractor.
NOTE: It is extremely important to design and install
the fresh air intake in an area where the hoods will
gather the freshest air, free from restriction.
Recommended:
• no less than 10 ft. (3 m) apart from each other
• at least 18 in. (46 cm) above ground level
• away from sources o
f contaminants, such as
automobile exhaust fumes, gas meters, garbage
containers, cooling towers, etc.
• not exposed to prevailing winds, whenever
reasonably possible.
The outside perimeter of the weatherhood must be
caulked to prevent leakage into the building.
The design and size of the weatherhoods or louvers
chosen by the installer must allow for adequate free
area. Water and snow penetration of the system is
minimized when the airflow does not exceed 750 FPM
(3.81m/s) free area velocity.
DuctingfromtheWeatherhoods
Galvanized sheet metal ducting with sufficient cross
section with an integral single piece vapor barrier
should be used to connect the HRV to the
weatherhoods. All ducting must meet ULC Class 1 Fire
Rating.
A minimum R value of insulation should be equal to 4
(RSI 0.75), or as stated in local codes.
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 and the weatherhood.
Warm-sideDucting - General
Ducting from the HRV to different areas within 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. 45Þ elbows are preferred
to 90Þ elbows, whenever possible. Use Y tees instead
of 90Þ tees whenever possible.
All duct joints must be fastened securely and wrapped
with a quality duct tape to prevent leakage. We
recommend aluminum foil tape.

Ducting - Distribution
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. Return air suction points should be
located at the opposite side of the room to 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, vapors 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
heat recovery 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 remo
ve 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 the chemical data sheets.
FreshAirSupplySystem
The fresh air supply ductwork from the HRV may be
directly connected to the return air duct of the forced
air system. When directly connected it is recommended
that the air handler blower be in constant operation to
move the fresh air about the building Also, it is
advisable to include a short length of fabric flex
duct o
r other non-metallic connector in this hard
ducted line in order to keep the HRV 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, the designer and installer
should be aware of local codes that may require smoke
detectors and/or fire stats in the HVAC or HRV
ductwork. Because an HRV is designed to bring fresh
air into the building, structures may require a supply
voltage interrupt when smoke or flame sensors are
triggered or 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. Information
on electric or hydronic heaters is available through Airia.
ElectricalConnections
System is 240V, 1 phase, 60 Hz. This unit meets all
local codes and requirements.
I
t is STRONGLY recommended that an electrical
disconnect be installed prior to the HRV, and that it is
turned off and locked out before servicing the unit.
Balancing
The 1500I-ECM/1500E-ECM has been programmed to
provide constant airflow on each airstream for external
static pressures of up to 1” w.g.
Within this range, each airflow can be adjusted
as described in “Adjusting the Airflow” section of this
manual.
All electrical connections should be made by a qualified
electrician.
Two (2) knock-outs are provided. One is to be used for
line voltage, and the other one for 24V control wires.
Beyond 1” w.g. of external static pressure, a balancing
damper may be required on the higher
airflow. See “Pitot Tube Air Flow Balancing” in this
manual.

TheIntegratedHVAC
System
The HRV/ERV has become an integral component of the
HVAC sy
stem. 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.
FigureA
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 wo
uld 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 .
CAUTION
When interlocking a rooftop unit with
an HRV/ERV, care must be taken to ensure
the fans of both units operate in the correct
rotation.
It is necessary to have balanced air flows in an HRV. 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 may not operate at its maximum efficiency
•A negative or positive air pressure may occur
in the building
•The unit may not defrost properly
•Failure to balance HRV properly may void warranty
Excessivepositivepressure 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.
Excessivenegativepressure 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'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
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 adjusted back to match the lower reading. See Adjusting theAirflow.
7. Return unit to appropriate fan speed for normal operation
BALANCINGPROCEDURE
The following is a method of field balancing an
tube, advantageous in situations when flow stations are not installed
in the ductwork. Procedure should be performed with the
speed.
The first step is to operate all mechanical systems on high speed,
which have an influence on the ventilation system, i.e. the
itself and the forced air furnace or air handler if applicable. This will
provide the maximum pressure that the
HRV
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
manometer capable of reading 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.
HRV
using a Pitot
HRV
on high
HRV
will need to overcome,
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 manometer).
Adjust the higher airflow by reducing the fan speed (see
“Adjusting the Airflow”). 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 meters 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:
DUCTDIAM. (inches)
5 (127 mm)
6 (152 mm)
7 (178 mm)
CROSSSECTIONAREA (sq. ft.)

0.20

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.
