HRV LED function indicators
Note: a flashing LED is an indication that an external timer
or dehumidistat has initiated a high speed ventilation sequence.
Operating Features
Any of the following operating functions may be selected at the push button
located at the left hand side of the HRV immediately below the illuminated leds,
or at the optional Shepherd Digital control if installed.
System Off
The Ventilation system is turned off and will not respond to any control devices.
Caution, HRV control device is powered in this mode.
Auto/Off
The ventilation system remains in standby mode. When an optional timer control
is activated the HRV will turn on to high speed ventilation until the timer has
expired or is turned off. The system will reset to Auto/Off
Ventilation Low
The System operates in continuous low speed ventilation. When an optional
timer control is activated, the system will switch to high speed ventilation until
the timer has expired or is turned off. The system will then reset to low speed
ventilation.
Ventilation Med
The system operates continuously in medium ventilation speed. When an
optional timer is activated, the system will switch to high speed ventilation until
the timer has expired or is turned off. The system will then reset to medium
speed ventilation.
Ventilation High
The ventilation system operates continuously in high speed ventilation.
Intermittent
Off
During this cycle the ventilation cycle remains in the off state for a period of 40
minutes. However, should an optional timer be activated, ventilation will turn on
to high speed until the timer expires or is turned off.
On
During this cycle ventilation is ON for a period of 20 minutes in low speed.
8
However, should an optional timer be activated, ventilation will turn on to high
speed until the timer expires or is turned off.
This intermittent cycle of 20 minutes ventilation ON followed by 40 minutes of
ventilation OFF repeats automatically until another selection is made.
Defrost
When all LED’s are illuminated the HRV is in an automatic defrost cycle for
approximately 7 minutes. During this time minimal ventilation occurs. The HRV
will automatically reset to the selected mode upon completion of the defrost
cycle. There may be water flowing in the drain line during this cycle. This is
normal.
All operating cycles may be automatically interupted by defrost cycle.
Should a power interruption occur, the HRV control will reset to the mode of
operation selected.
The current mode of operation is displayed at the LEDs located on the front
panel of the HRV.
OPTIONAL CONTROLS
Installation of a user-accessible control with your product will improve comfort
and may significantly reduce the product’s energy use.
Guardian Control
The Guardian control allows the user to monitor and set
the system operating mode. The currently selected mode
is displayed in bold. The diagram at left shows the LCD
display with Fan Medium Speed mode selected.
If desired, the push-button may be pressed ONCE to turn the
backlight on for easier viewing.
The control also allows Relative Humidity to be monitored.
The Guardian acts as an automatic humidity control. A humidity
threshold is set. When the measured humidity exceeds the
setting the system switches to high speed ventilation until
the humidity has been reduced below the threshold.
NuWave Digital Control Model - SHEPHERD
This SHEPERD control must be connected to the LCD &
COM terminals on the HRV exterior. The SHEPHERD is a
wall mount liquid crystal display device.
This control provides the opportunity to select all available
operating features of the HRV.
Simply push the select button once to highlight the screen.
9
Continue to press the select button until the desired fearture
is highlighted.
The HRV will then assume the selected mode of operation.
Install using 18/2 thermostat wire or telephone wire up to
two may be installed per HRV. No electrical box is required.
Refer to wiring diagram in this manual.
20 Minute Remote Timer Touch Pad
Model ECPBT
This 20-Minute Touch Pad MUST be connected to the PBT
& COM terminals on the HRV exterior.
Install using 18/2-thermostat wire or telephone wire. No
electrical box is required. Maximum number of ECPBT
controls per HRV is six (6).
Maximum cumulative lead length is 2000 lineal feet. Touch
pads are typically installed where 20 minutes of high speed
ventilation may be desired.
Once activated by a momentary push of the SELECT
button on the Touch Pad, the HRV switches to high speed
ventilation and the Touch Pad LED will illuminate. The
HRV will reset to the previously selected mode of operation
once the 20 minutes have expired. To cancel the selection,
momentarily depress the SELECT button on the 20-minute
Touch Pad. The selection can also be cancelled at any fan
timer control by momentarily depressing the SELECT button.
Should a dehumidistat be activated then the LED on this 20
minute timer will illuminate until the dehumidistat is turned
off or automatically resets.
NOTE: This control will not respond while a crank timer or
dehumidistat is operational.
Wall Mount Dehumidistat Model - SRDEH
This dehumidstat must be connnected to CT & COM terminals on the HRV exterior. This control is typically installed
in an area of the home where humidity may require automatic
monitoring. This could be a central location (i.e. near furnace
thermostat) or in a specific room (i.e. kitchen, laundry etc.).
Connect to HRV using 18/2 thermostat wire or telephone
wire. No electrical box is required.

1. Selecting a location
Typically the HRV is located in the
mechanical room with close proximity
to an outside wall. Other installation
locations are acceptable provided that
the ambient air temperature does not
fall below freezing. This is to prevent
the condensate drain lines from freezing.
11
2. Mounting the HRV
Included with the HRV are four (4) laminated rubber hanging straps. These are
to be secured at each of the four corners of the HRV using the screws provided.
The other ends of the straps should be secured to the floor joists using large head
screws. To ensure proper condensate flow, HRV must be installed level in both
directions.
To ensure quiet operation of ENERGY STAR qualified HRV/ERV’s, each
product should be installed using sound attenuation techniques appropriate for
the installation.
3. Condensate Drain hose installation
Two (2) drain spigot assemblies are provided. These are to be installed through
the drain pan holes provided. Simply install the spigot through the openings
and secure in place by installing the nylon washer and nut on the outside of the
cabinet. Once installed, attach 1/2” plastic tubing (not supplied) to the spigots.
Create a trap by forming a loop in the tubing. This will prevent the cross
contamination of the air streams through the tubing. Ensure that the condensate
drain tubing is not exposed to freezing temperatures. Typically the drain line is
connected into a floor drain, sink or stand pipe.

ATTENTION!
Contact your local building authority before installation of the Concentric Vent
to verify compliance with local building codes.
CAUTION!
Sealant must be applied as per instructions or leakage and condensation may occur.
ATTENTION!
Insulate the Fresh Air Supply and Stale Air Exhaust ductwork back to the unit.
Weather hoods should be installed:
• Separate air intake and exhaust outlet openings, when located on the same
wall or roof, shall be installed so as to avoid contamination of the ventilation air
by the exhaust air.
• Intake openings shall be located so as to avoid contamination of the
ventilation air from other local sources such as automobile exhausts and exhaust
from adjacent buildings.
• The distance from the bottom of an air intake opening to finished ground
level or to any nearer and lower permanent horizontal surface shall be not less
than 450 mm or the depth of expected snow accumulation, whichever is greater.
• The distance separating air intakes from building envelope penetrations that
are potential sources of contaminants, such as gas vents or oil fill pipes, shall be
not less than 900 mm.
• Locate away from prevailing winds whenever possible.

Vapour Barrier
The outside weather hoods must have built in bird screens to prevent birds and
rodents from entering the duct system. Minimum mesh size of 1/4” must be
used. Smaller mesh size will result in restricted air flows with increased potential
for the development of blockages.
The size and design of the weather hoods shall be selected to ensure adequate
free area to minimize air flow restrictions.
It is recommended that 6” insulated ducting with a integral single piece vapour
barrier be provided. Due to the high air flow restrictions in insulated flex duct
it is recommended that run lengths be kept to a minimum, stretched tightly and
with as few elbows as possible, if length greater 25 ft. use 7” insulated duct.
Minimum RSI value of 0.75 (R4) is required.
Weather hood collar should be screwed to inner surface of sill plate and sealed
with high quality caulking or aluminum faced tape. Both the inner and outer
liners of flexible ducting should be securely attached to the weather hood
tubing and collar and to the HRV collar. A good bead of high quality caulking
(preferably acoustical sealant) should be used prior to clamping the liners. It is
very important to ensure that the fresh air intake line is well sealed and that the
vapour barrier is sealed.

Dedicated Installation
In this arrangement the HRV is installed with a dedicated duct system. All
applicable rooms are exhausted and provided with fresh supply air as required.
This type of installation provides exhaust and supply air to each serviced room.
The HRV system operates independent of the home’s heating system.
Please refer to fig III. below.

6. Interior Ducting
Ducting to the central forced air ductwork system, or if used, a dedicated duct
system, should be made of galvanized metal whenever possible.
To minimize airflow losses, runs should be kept as short as possible using 45
degree elbows instead of 90 degree. Whenever possible use “Y” fittings instead
of “T” fittings.
All joints must be fastened with screws, rivets or duct sealant and wrapped
with a quality duct tape to prevent leakage. If standard grills are used, it is
recommended that wall grills of not less than 6” x 12” and floor grills of no less
than 4” x 10” be used to minimize air flow restrictions.
7. Fresh Air Supply Ducting
Fresh air supply ducting to the living space may be either a dedicated or an
indirect duct system. Please refer to figures II and II.
Should the indirect method be used it is suggested that at the point of
connection to the HRV that a short length of flex duct be used to electrically
isolate the two systems.
Fresh air supply grills may be either wall or ceiling mounted. Avoid locating
these grills where room occupants may be exposed to the fresh air supply as this
air temperature may be slightly less than the room air temperature.
Also, it is recommended that adjustable grills such as round “Tech Grills” be
used to permit balancing of the ventilation by room application.
20
8. Stale Air Return System
The stale air return system is used to extract humid, stale air from the areas
of the dwelling where the worst air quality conditions might exist. These may
include areas such as laundry rooms, bathrooms and kitchens. Note that C.S.A.
Standard F326 requires that air be exhausted from each room with a forced air
furnace.
Wall stud spaces can be used as ducting for high wall returns provided that they
are lined with galvanized metal.
Note: Check local code compliance before implementing.
Adjustable “Tech Grills” are recommended for use in the return air system. They
can be wall or ceiling mounted thereby permitting balancing of the air being
exhausted. Stale air return grills should be located at opposite ends in the room
to the fresh air grills to ensure good air exchange.
Please note that the exhaust air stream from a kitchen area must never be
connected to the kitchen range hood. Instead an exhaust grill should be mounted
high on the wall as required by local codes so as not to extract cooking by
products.
9. Air Flow Balancing
READ THE APPLICATION WARNING AT THE FRONT OF THIS MANUAL.
A magnehelic gauge and pilot tube flow measuring system is used for
easy and accurate air flow measurement
Upon completion of the installation it is necessary that the Ventilation System
be balanced. This is necessary to ensure that the volume of air being exhausted
from the dwelling is equal to the volume of air being supplied. Balancing will
also ensure that the HRV is operating at it’s maximum efficiency.
Detailed check list to be carried out prior to balancing.
a)
b)
c)
d)
e) Install air flow station in each of the warm air streams.
Ensure that all ductwork is secured and sealed.
Drain connections are in place and drain trap filled with water.
Dwelling vapour barrier is complete and intact.
Fireplace dampers, windows and doors are closed.
21
f) Clothes dryer off, (if vented to the outdoors)
g) Furnace, hot water heater, (non direct vent) are turned off.
h) All other exhaust fans are off.
i) Ensure that HRV filters and core are in place and integral balancing dampers
are wide open.
j) Power up HRV and set to high speed.
k) Adjust all branch tech grills and registers to desired air flows.
l) After taking readings at both the stale air being exhausted and the fresh
air supply air stream, damper down the higher air flow stream with the
integral balancing damper to equal the lower volume air stream.
m) Once the air flows are balanced lock the balancing dampers in place.
n) While it is necessary to ensure that both air streams are balanced within
10% of each other, a near balanced condition should be possible.
o) Upon completion, return the fan speed selection to the normal speed of low.
A positive pressure situation within the dwelling may drive moist air into
the external walls of the dwelling where, in cold weather, it may condensate,
potentially causing structural damage.
A negative pressure within the dwelling may have severe undesirable effects.
In some geographic locations, radon gas may be drawn into the living space.
A negative condition may also cause back drafting of vented combustion
appliances such as fireplaces and furnaces.
When it is possible for excessive pressurization or depressurization of a dwelling
to occur it may be necessary to perform a House Pressure Test. This test is most
important where fuel fired devices are installed that are susceptible to spillage.
IT IS YOUR RESPONSIBILITY TO DETERMINE IF THE “HOUSE
PRESSURE TEST” IS REQUIRED.

Summeraire HRV Air Flow Balancing
Models: NW140, NW160, NW220, NW260
A. Preliminary Procedures:
1. Seal all the unit’s ductwork with foil tape.
2. Close all windows and doors and fireplace damper, turn off all exhaust
devices (range hoods, clothes dryer, bath fan, etc.), make sure all filters are clean.
3. Set build-in balancing dampers fully open. Tap 1/8” hole in ductwork for
pitot tube insertion.
B. Balancing Procedures:
1.Set HRV to high speed. Make sure that the furnace blower is ON if the
installation is in any way connected to the ductwork of the furnace. If not,
leave the furnace blower OFF. Adjust air flow in branch lines if using source
point exhaust and/or supply.
2. If outside temperature is below -3°C (26°F), make sure defrost light is not
on while balancing.
3. Place magnahelic gauge on a level surface and adjust it to zero. Insert pitot
tube into exhaust air ductwork with tip aligned with ductwork, pointing away
from HRV, into air flow. Record the reading on gauge.
4. Move kit to other air stream HRV, insert pilot tube into fresh air ductwork
with tip aligned with ductwork, pointing towards HRV , into air flow.
Record reading on gauge. Adjust fresh air balancing damper until reading is
approximately the same as in exhaust air ductwork. If the reading in the fresh
air ductwork is less than in the exhaust air, go back and adjust the exhaust
balancing damper to equal the fresh air flow.
5. Secure dampers in place with fastening screw. Duct tape over pitot tube
holes.Convert FPM reading on gauge to CFM with conversion chart and
record on balancing sticker and affix to HRV near label.
6. Note: Unit is considered balanced if readings are within +/- 10%.
