Direct Air PHRV 140 User manual

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 piec-
es of equipment must be confirmed by measuring the airflow’s of the Heat Recovery
Ventilators 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 com-
bustion 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 par-
tial failure may result in the backdrafting or improper functioning of vented combustion equipment!!!

period.
* This warranty is the exclusive and only
warranty in effect relative to the ventilation
system and all other warranties either
expressed or implied are invalid.
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 multi-
ply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by 0.35.
Example: SQFT of House 1100
Basement 1100
Total SQFT 2200
Height of ceiling x 8
Cubic volume 17600
/ 60
Maximum airflow required (CFM) 293
x 0.35
103
* Always consult your local code for sizing requirements in your area.

OPERATION
Winter:
Humidity control is very important during the winter months.
This is when problems will be most apparent since condensa-
tion 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 condensation. Low speed continu-
ous ventilation with high speed override is recommended.
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.
Powrmatic 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. Below are some examples of seasonal operation
of an HRV.
Spring:
Temperatures are more moderate and become
warmer each day. To keep the humidity and tem-
perature uniform, set the dehumidistat higher (if
installed). You may also switch the HRV to standby
mode if desired.
Summer:
The air is sometimes hot and humid. To stop the warm
humid air from entering, set the dehumidistat at its high-
est level. If the Intellitek series controller is installed, the
air exchanger can be set to cycle the unit on and off as
desired from that wall control. However, continuous ven-
tilation is recommended.
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 dehu-
midistat may help give greater control over the
inside environment.
The entire line of PHRV & PHRVR series Heat Recovery Ventilators comes equipped with Powrmatic's new electronic uni-control board which offers
a wide variety of features making it the ultimate ventilation control system. Powrmatic engineers have used the latest technology to provide solid,
trouble free operation under any conditions.
The Powrmatic uni-control board offers stand alone operating capabilities as well as an exclusive 2 wire communication to most external controls.
The trouble-free 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 Intellitek 5MR.
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.
4. Defrost (PHRV Models)
The automatic defrost cycle PHRV
models of HRVs consists of a fan
shutdown. When the supply air
stream temperature goes below
-5°C (23°F), the supply 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).
MODES OF OPERATION
1. Continuous / Ventilation Mode
In this mode of operation both fans
are operating and exchanging air with
the outside. The heat recovery ventila-
tor (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.

2. Intermittent / Standby Mode
The system is always on standby and operates
at high speed when activated by an optional
remote control. "Standby" should be selected if
the user wishes to stop the unit from continuous
exchange. We recommend that the "Standby"
mode only be used if your system is equipped with an optional external
control, in which case, the unit would activate to "High" fan speed, until
the control is satisfied and then return to standby (off).
* no exchange of air
3.Defrost/Recirculation Mode
(PHRVR Models)
The automatic defrost cycle PHRVR mod-
els of HRV 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 Intellitek EDF5 (5MR) control.

15-min Timer - 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.
Air Quality Sensor - 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.
Dehumidistat II - The wall mount dehumidistat II offers the same features of the
dehumidistat I plus additional off/on control for the HRV. Dial illuminates when
in override mode.
Dehumidistat I - 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.
To avoid window condensation:
• It is not necessary to
change the humidity control
every day. Monitor the
average weekly
temperature or experiment
with various settings until
you find a level that is
comfortable for you. Adjust
the control when needed.

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

PRACTICAL TIPS
3 Hang the unit by
slipping a link onto the
hanging hooks, making
sure the unit is level.
2 Attach a hanging chain
(provided) to each 10 3/4”
(19 mm) bolt (provided) in
the top 4 corners of the
unit and tighten.
1 Place Fastening hooks
on the strapping board
or the floor joists.
1 Install the drain nipple.
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.
MOUNTING
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

3 Push the hood into
the opening. Attach
the hood to the
outside wall with
mounting screws.
Repeat the installation
procedure for both
the Supply and
Exhaust hood.
2 Pull the insulated
flexible duct through
the opening until it is
well extended and
straight. Slide the
duct’s inner vinyl
sleeve over the hood
collar and secure, pull
the insulation over
the duct and then the
vapor barrier over the
sleeve and secure
with duct tape.
4 Using a caulking
gun, seal around
both hoods to
prevent any
leaks.
1 Using the collar of
the outside hood,
outline the intake &
exhaust holes to be
cut. The holes should
be slightly larger
than the collar to
allow for the
thickness of the
insulated flexible
duct. Cut a hole
for both the intake
and exhaust hoods.
• Decide where your intake and
exhaust hoods will be located.
PRACTICAL
TIPS
INSTALLING DUCTS GOING TO / FROM OUTSIDE
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 weath-
erhoods (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 caulk-
ing (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.
Locating the Intake
Weatherhood
• Should be located upstream
(if there are prevailing winds)
from the exhaust outlet
• At least 6’ (2m) from the
exhaust weatherhood
• At least 6’ (2m) away from
dryer vents and furnace
exhaust ( medium or high effi-
ciency furnaces)
• A minimum of at least 6’ (2m)
from driveways, oil fill pipes,
gas meters, or garbage con-
tainers
• At least 18” (457mm) above
the ground, or above the
depth of expected snow accu-
mulation
• At least 3’ (1m) from the cor-
ner of the building
• Do not locate in a garage,
attic or crawl space
Locating the Exhaust
Weatherhood
• At least 6’ (2m) from the ven-
tilation air intake
• At least 18” (457mm) above
ground or above the depth of
expected snow accumulation
• At least 3’ (1m) 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 weather-
hood, it’s outside perimeter
must be sealed with exterior
caulking.

PRACTICAL TIPS
INSTALLING DUCTS TO / FROM INSIDE
• 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 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). from HRV
For minimum distance
See local building codes
and practical tips.
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 such as Powrmatic grille 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).

16
• 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.
• 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.
INSTALLING DUCTS TO / FROM INSIDE (CONT'D)
PRACTICAL TIPS
2 Working 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.
3 The 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.
Dedicated Installation for Existing Home -
(non forced air heating / cooling system)
1 Begin 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.
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 recom-
mended 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.

DUCTING FIFTH PORT UNITS (R)
All PHRVR HRV’s have a fifth duct port on top or side 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.
INSTALLATION EXAMPLES
Example diagram only-duct configuration may change depending on model
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 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.
