i CAUTION!
Do not install in a cooking area or connect directly
to any appliance. Turn off all integral disconnects
before servicing.
Notice: Prior to installing, serious consideration must
be taken to ensure this ventilation system will operate
properly if integrated with any other type of mechanical
system such as a forced air system or an air handling unit.
To ensure proper operation and compatibilities of both
systems, the airflows of the Heat Recovery Ventilator
(HRV) or Energy Recovery Ventilator (ERV) must be
balanced by the installer, by following the procedures
found in this manual.
The way in which your HRV/ERV is installed may make a
significant difference to the electrical energy consumed
when operating. To minimize the electricity use of the
HRV/ERV, a stand-alone fully ducted installation is
recommended. If you choose a simplified installation that
operates your furnace or air handler for room-to-room
ventilation, electrical energy consumption and operating
cost will be greatly reduced if the blower of the system's
furnace or air handler has an electronically commutated
(ECM) motor.
Limitations: The product is for residential applications
only and must be installed in accordance with all national
and local regulations, building and safety codes.

VENTILATION REQUIREMENTS
Determine Your
Ventilation Needs
Good indoor air quality is based
in part on the capacity of the
home’s ventilation system.
The two most common
methods for determining the
ventilation needs of a home are
the Room Count Calculation
method and the Air Change
Per Hour method. Both
methods calculate an
approximate ventilation rate
(in CFM or L/s). Their calculation
methods are described on
this page.

1 CFM = 0.47189 L/s
1 L/s = 3.6 m3/hr
B. Air Change Per Hour Calculation Method
TOTAL volume of the house (in cubic feet) X 0.35 air changes/hour = CUBIC FT/HR
Take total CUBIC FT/HR and divide by 60 to get CFM
Example: A 25'x 40' house with basement:
25' X 40' = 1,000 sq. ft.
1,000 sq. ft. x 8' room height x 2 storeys
(1st floor + basement) = 16,000 cu. ft.
16,000 cu. ft. x 0.35 ACH = 5,600 cu. ft.
5,600 cu. ft. / 60 = 93.3 CFM
93.3 CFM is your ventilation requirement

TYPES OF INSTALLATIONS
Independent System Installation
From an Indoor Air Quality standpoint, this is the preferred method of installing a ventilation system in a home.
This installation uses a dedicated duct system for both the
supply of fresh air and exhausting of stale air accumulated
in the home.
With an Independent System installation, fresh air is
supplied to all bedrooms and living areas and stale air is
exhausted from the bathroom, kitchen and laundry room.
See Figure 1.
Important: For correct performance of your HRV or ERV,
the installation of a 6" round galvanized backdraft damper is
required on the ductwork supplying fresh air to the home.
Figure 1
Exhaust at the Source and Supply
in the Return
This application uses a dedicated duct
system for exhausting the stale air
from the home. The fresh air is routed
to the return air duct and is distributed
through the home by the existing
supply air ductwork of the forced-air
system. See Figure 2.

Make sure when using this installation that
your fresh air duct connection to the forced
air system return air duct is not less than 10ft (3 m)
upstream of the return plenum connection to the
forced-air system. Check with your local building codes
or the manufacturer of the forced-air system. The HRV
and forced-air system must be set to operate in continuous mode to achieve maximum comfort and to avoid
cross-contamination.
Note to Installer: Dwellings with multiple forced-air
systems require one HRV/ERV per system.
Ensure the unit runs in conjunction with the forced-air
system. Refer to wiring diagram for furnace interlock
instructions.

damper to balance the outdoor airflow.
Important: For optimal performance of your HRV or
ERV, the installation of an optional 6" round galvanized
backdraft damper is required on the fresh-air-to-home
duct work. When performing duct connections, always
use approved tools and materials. Also use steel duct
connections for this type of installation.

TYPES OF INSTALLATIONS
Exhaust and Supply in the Return
When using this installation, make sure that there is
minimum of 3 feet (0.9m) between the fresh air
and exhaust air connections of the HRV/ERV in
the return air duct. See Figure 3. Make sure
when using this installation that the fresh air duct
connection to the forced-air system return air
duct is not less than 10ft (3 m) upstream of the
return plenum connection to the forced air system.
Check with your local code or the forced air system's
manufacturer. The HRV and forced-air system must be
set to operate in continuous mode to achieve maximum
comfort and to avoid cross-contamination.
Note to installer: Dwellings with multiple forced-air
systems require one HRV/ERV per system.
Ensure the unit runs in conjunction with forced-air system.
Refer to wiring diagram for furnace interlock instructions.
Important: Building and combustion appliance installation codes
do not allow return air grilles or
openings such as "breather tee" or
indirect connections in an enclosed
room that is susceptible to spillage of
combustion appliances.

Installation Kit
Installation Kit Includes:
• 4 Collars
Finding a Suitable Installation Location
• 12 screws (#10 x 11/4”)
• 4 Caps, Pressure Taps
• 2 screws (#8 x 3/8”)
• 1 Condensation Drain Line • 120VAC power cord
• 1 Drain Adapter with Nut
• Wall-Mounting Bracket
The HRV/ERV unit should be installed in a mechanical room
or as close to an outside wall as possible. This would ensure
a short run of insulated flexible duct.
The HRV/ERV unit must always be installed in an area where
the air is tempered to avoid freezing of the condensate
line. The contractor should install the unit in an area that
is accessible to allow the homeowner easy access for for
performing maintenance.
It is very important to install an electric receptacle (120VAC)
near the HRV/ERV. A separate circuit breaker is also recommended. Installing the HRV/ERV close to a drain for the
condensate would avoid the need for a condensate pump.
Figure 4
Tip to Installer: Removing the core unit will facilitate
your installation.

INSTALLATION
Installation of the HRV/ERV
IMPORTANT Minimum installation requirements:
a) Minimum two 2"x 4" (50.8 mm x 101.6 mm) wood
wall studs and minimum ⅜" (9.5 mm) thick drywall is
required to secure the HRV/ERV wall bracket.
b) Support for weight of 80 lbs, which includes HRV/
ERV, duct connections and accessories. Proper installation requires that the unit be secured to the wall. If
there are no wall studs available, secure a sheet of ¾"
plywood to wall then fasten wall mounting bracket
to plywood.
Tip to installer: If the unit is not level, improper
drainage will occur and could lead to moisture and
leakage problems.
It is recommended that approximately 16 inches of flexible
duct be installed between the HRV or ERV and your rigid
duct. The flexible duct is connected to the HRV or ERV in
the same way as the insulated flex.
NOTE: Clean Comfort Ventilators (HRV/ERV) that use a
fan shut down defrost sequence for frost protection are
NOT equipped with a motorized outdoor air damper.
Special consideration is required when one of the following types of installations is chosen:
a) Exhaust at the source and supply in the return air duct,
or
b) Exhaust and supply in the return air duct
The HRV/ERV must operate in the continuous ventilation
mode to avoid cold, unconditioned air being introduced
through the unit and directly into the furnace during
heating season. However if the homeowner chooses to
run the unit in Intermittent (“INTER”) mode or turn it
“OFF”, cold supply air will be drawn in through the HRV/
ERV when the system’s blower fan is operating e.g. during
a heating cycle. We recommend installing a motorized
damper between the HRV/ERV supply air connection
and the furnace’s return air duct that will automatically
close when the HRV/ERV is not operating. You may also
consider the installation of a backdraft damper on the
ventilator’s exhaust air connection to prevent cold air
infiltration.
Alternatively, installing a ventilator that employs a
recirculating defrost sequence and is equipped with
an integrated motorized outdoor air damper, such as
the VH30120R or VH30160R, would avoid the problem
described above.
Figure 5 Installation of the wall bracket. Secure with two
#10 x 11 ⁄4" screws.
Figure 6 Hang HRV/ERV on
the wall-mounting bracket.
Insulated Flex from Unit to Outside Wall
Tip to installer: To ensure a better installation and to
avoid an undesired bend in the duct, align the flexible duct
with the collar before securing over the four hooks on the
inner surfaces of the collar.
Figure 7 Before completing
the installation, make sure
that the HRV/ERV is level.
All ducting to and from the HRV/ERV must be adequately
insulated to minimize heat loss and gain. All tapes,
mastics, and nonmetallic clamps used for field installation
of flexible ducts shall be listed and labeled to Standard UL
181B - Closure Systems for Use With Flexible Air Ducts and
Air Connectors.
Once insulated flex is attached to the collar, slide collar into
the keeper section and attach collar to the unit with four,
#10 x 5/8" screws supplied in installation kit to ensure a
proper seal. See Figures 9-13 on following page.

CAUTION! Always consult
your national and local
regulations, building and
safety codes.
i WARNING!
Always secure the 5" detachable collars with the screws
provided. If this is not done, condensate may accumulate
inside the ventilator causing damage.
Condensation Drain Line
Insert the threaded drain adapter through the bottom of the
HRV/ERV and hand tighten the plastic nut supplied with the
installation kit. Use a wrench to tighten the nut another half turn
to ensure a complete seal.
Figure 15 Use a condensate pump if you don’t have access to a drain.
Supplying Power to the HRV/ERV
IMPORTANT: Only qualified service technicians should
install, repair, or service this HRV/ERV.
NOTE: If the LED light on the unit's control is lit (green),
but the unit's motors do not energize and the controls do
not operate, this indicates that the polarization in the main
power supply outlet is inverted. Correct polarity of supplied
power before continuing with the installation.
Daikin recommends that the unit be connected to a dedicated 120VAC receptacle; use of an extension cord to power
the unit is not recommended. If no receptacle is available
near the unit, have a licensed electrician install one.
Install the condensate line (included in installation kit) by
pushing the clear plastic tubing over the drain adapter. Make
a condensate trap by looping the clear plastic tubing. The
function of this condensate trap is to prevent unpleasant odors
from entering the HRV/ERV. See Figures 14-15.

SEQUENCE OF OPERATIONS
Sequence of Operations for Ventilator and
Connected Wall Controls and Timer
There is a low voltage ventilator control mounted on the
HRV/ERV to operate the ventilator in Intermittent (INTER)
or Continuous (CONT) operation. When a VHP-RD3P wall
control is connected to the ventilator, it can override the
setting on the ventilator as described in the table below.
Ventilator Control
Setting
In addition, the VHP-RD3P has the ability to operate
the ventilator at a reduced speed by setting the RANGE
selector on the VHP-RD3P to the REDUCED position. In
this position, the ventilator will run at 15% slower fan
speed in CONT mode and 30% slower in Override (High)
speed when responding to a high humidity signal from
the VHP-RD1 or VHP-RD3P wall control or when the
VHP-T3 timer is activated.

INTER position, the unit runs only on a call for ventilation from an external wall control or timer. It will then
run on high speed until the call is satisfied.
The low voltage ventilator control mounted on the HRV/
ERV has a three-position selector switch and buttons
(marked “+” and “–” ) to adjust fan speed. The color of the
LED light located above the selector switch indicates the
operating mode of the control as follows:
• LED is GREEN = Control is in Run mode
(normal operation)
• CONT (Continuous): With the selector switch in the
CONT position, the unit runs continuously (low speed)
until there’s a remote call for ventilation (override)
from an external control.
• OFF: When the selector switch is in the OFF position,
the ventilator will not operate even if there’s a remote
call for ventilation from an external control.
• LED is YELLOW = Control is in Balancing mode

(+) and (–) buttons: These buttons are used for adjusting
both the high and CONT fan speed settings when the
control is in RUN mode.
4. When in Balancing mode, the selector switch becomes
the motor selector switch. The switch position selects
which fan motors will be adjusted during balancing.
BALANCING Mode
When the control is set to Balancing mode, the LED
indicator turns yellow and the selector switch is used for
setting the high speed of the fans for balancing purposes
(Supply (fresh) air, Exhaust air, and Both). The options are:
• INTER (Intermittent): With the selector switch in this
position, the speed of the exhaust air fan can be set
• CONT (Continuous): With the selector switch in this
position, the speed of BOTH the exhaust and supply air
fans can be set
5. Adjust the airflow rate in the fresh air duct by setting
the selector switch to the OFF position.
6. Connect the airflow measuring device to the integral
balancing taps on the ventilator's collars.
• OFF: With the selector switch in this position, the speed
of the supply air fan can be set.
HIGH (Exhaust Air to Outside)
(+) and (–) buttons: These buttons are used for adjusting

Procedure for Setting High (Override)
Airflow Rate and Balancing the Ventilator
To balance the ventilator, you will need to independently
adjust the flow rate in both the fresh air (supply) duct as
well as the stale air (exhaust) duct. You will need an airflow
measuring device such as a pitot tube or a Magnehelic gauge.
NOTE: Turn the HVAC equipment fan ON while
performing these balancing steps
1. Once the total CFM needed is determined (see
Ventilation Requirements section), you can start
balancing the HRV/ERV.
2. Set the three-position selector switch on the ventilator
control to either the INTER or CONT position.
3. Press and hold both the (+) and (–) buttons
simultaneously for 5 seconds until the LED light turns
yellow, indicating the unit is now in Balancing mode.

BALANCING THE UNIT
2. Release both buttons
8. Perform the same operation on the stale air side by
selecting the INTER position on the selector switch.
Adjust the airflow rate in the stale air duct to be the
same as the airflow rate in the fresh air duct, so the
airflow entering and leaving the building is balanced.
Testing the Ventilator to Confirm Operation
9. If necessary, the selector switch can be set to the CONT
position, which will adjust the speed of both fan motors
at the same time.
1. Apply power to the ventilator. Set the selector
switch to the CONT position. Verify that the unit
turns on and operates at continuous speed
10. Once this is done, you have set and locked the high
speed on your ventilator and balanced the fresh and
stale airflow rates.
2. Turn the wall control to minimum humidity setting to
create a call for ventilation. Verify that the ventilator
turns on and operates at high speed. Return wall
control to normal humidity setting.
3. Unit has now been reset and is ready for rebalancing, if necessary
11. To exit Balancing mode, press the (+) and (–) buttons at
the same time until the LED turns green, indicating that
the control has returned to Run mode.
Procedure for Setting Low
(Continuous) Ventilation Rate
When the unit is in Run mode, the continuous airflow rate
can then be set by using the (+) and (–) buttons and reading
the CFM using the airflow measuring device.
1. When the unit is in Run mode, the continuous
airflow rate can then be set by using the (+) and (–)
buttons and reading the CFM using the airflow
measuring device.
2. When the selector switch is set to the CONT position,
the ventilator runs at the low (continuous) speed until
there’s a remote call for ventilation (override) from an
external control such as the VHP Series of controls.
Balancing Reset
Balancing of the ventilator is locked upon exiting Balancing
Mode and can only be changed with a reset of the control.
To Reset Control
1. Press the (+) and (–) buttons simultaneously for 10
seconds. After 5 seconds, the LED will turn yellow and
after 10 seconds, it will turn green
3. Repeat for timer control, if one is installed
4. Return the selector switch to the desired position
(INTER or CONT) and the wall control to the desired
settings
5. Inspect the ductwork to verify there are no bends,
kinks or obstructions to airflow. Correct as needed.
*Important: Once balancing is complete, ensure all four
pressure taps are sealed with the rubber caps. Pressure taps
are supplied in the installation kit.
Balancing chart
This balancing chart is based on a Delta P (DP) reading from the
airflow measuring device. A copy of this chart is also located on
the access panel of the ventilator.
Note: To perform a proper installation, the External Static
Pressure (ESP) needs to be measured at each of the 4 stations.
Proceed to measure the Delta P (DP) to determine the corresponding airflow (e.g. 50 CFM), then repeat until the unit is
balanced for both the ESP and airflows.

MAINTENANCE
Routine Maintenance
4. Clean the condensate drain and pan
Seven-Step Maintenance Schedule
With routine preventative maintenance, you can avoid
unnecessary problems, ensure the effectiveness of
your ventilator, and prolong its life.
i WARNING!
Twice a year, check the condensate drain, pan and
tubing to ensure that they are open and free-flowing.
The tubing can be disconnected for cleaning. The
condensate drain must have a “trap” in the tubing
that traps a quantity of water and helps prevent
unpleasant odors from entering the ventilator via this
tubing.
5. Inspect the fans
BE SURE TO DISCONNECT THE ELECTRICAL
POWER BEFORE SERVICING YOUR SYSTEM
1. Clean or replace air filters
Filters, which are located within the ventilator, should
be cleaned every two to three months. Filters should
be vacuumed first, then washed with a mild soap and
water. Most washable filters will last several years
before needing to be replaced.
2. Clean the exterior intake and exhaust vents
of obstructions
Check the outside vents regularly to ensure that the
screen openings are not obstructed by grass, bushes,
leaves, snow or other debris.
3. Clean and inspect the heat-exchange core
Do this twice a year and clean the core as required.
Consult the Installation and Operation manual for
instructions on inspecting and cleaning the core. A
build-up of dust and dirt can restrict airflow and reduce
the efficiency of the ventilator. After inspection and
cleaning, make sure the core is replaced right-side-up.
The fan motors on the ventilator are designed to
operate continuously without lubrication and should
not require inspection. Inspect the blower fans
periodically for dirt on the blades, and remove it by
gently brushing the blades or using a vacuum cleaner.
6. Clean the grilles and inspect the ductwork
Clean the grilles when they are dusty. At least once
a year, visually inspect the ductwork leading to and
from the ventilator. Damaged ducts can lead to
condensation problems, including wet insulation,
water on the floor and, ice build-up.
7. Arrange for an annual servicing
Your ventilator should undergo annual general
servicing by a certified contractor who is familiar
with its operation. If possible, have your furnace and
ventilator serviced at the same time.
