What are HRVs?
To understand these products and their functions, here are a few
things to remember.
Heat Recovery Ventilators (HRVs)
are recommended for colder areas of the country that have longer
heating seasons as well as drier desert areas of the South.
Heat Recovery Ventilators are complete whole house ventilation
systems that incorporate a supply fan and an exhaust fan in one
unit. The supply fan draws fresh air in from the outside and the
exhaust fan pushes stale contaminated air out. The two air streams
are separated by a heat recovery core which tempers the air,
making it the most comfortable solution for a healthy indoor
environment.
For information on how these units can help you save energy and
lower heating or cooling costs, read “How Do They Work?”.
Port Configuration
Five Port Models feature motorized damper for recirculation mode and defrost. Positive shut off of supply port when unit is in standby.
Four Port Models provide constant ventilation even in defrost mode without the need for additional parts. An exhaust only (fan shut down) defrost
strategy is an effective method at an affordable price.

How do They Work
Heat Recovery Ventilators (HRVs)
An HRV is designed to be a cost-effective and reliable way to bring a
continuous supply of fresh air into a home while exhausting an equal
amount of contaminated air. If it is properly maintained, an HVR can
meet a home’s total ventilation requirements by itself. HRVs use
what is called a “sensible” heat recovery core. This special aluminum
core transfers heat from the exhaust air stream to the incoming air
stream. Fresh incoming air is tempered by the heat that is
transferred from the outgoing air so you save on energy costs.
Fantech HRVs are equipped with automatic defrost mechanisms so
even if you live in the coldest climates, you can use your HRV all
year long.

Operation
Winter:
Humidity control is very important during the winter months. This is when problems will be most apparent
since condensation 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 continuous 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 using the stale air that is being
exhausted.
Fantech HRVs are designed to run continously or intermittently, giving the homeowner complete control over their air quality. Continuous low speed
ventilation is recommended, which will help eliminate carbon dioxide, VOCs 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.
Some products may not be exactly as illustrated in the Operation Manual.
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 dehumidistat may help give greater control over the inside
environment.
Summer:
The air is sometimes hot and humid. To stop the warm humid air from entering, set the dehumidistat at its
highest level.
Spring:
Temperatures are more moderate and become warmer each day. To keep the humidity and temperature
uniform, set the dehumidistat higher (if installed). You may also switch the HRV to standby mode if desired.

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 ventilator (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.
The switch on the side of the unit is used to toggle between STANDBY, LOW speed and MEDIUM speed modes.
In order to activate HIGH speed, a jumper must be placed between the DEHUM + and DEHUM - contacts.

4. Defrost/Fan shutdown (4 port models)
The automatic defrost cycle for SHR/VHR models of HRVs consists of a
fan shutdown. When the supply air stream temperature goes below
-5°C (23°F), the supply fan shuts down and the exhaust fan goes into
"High" speed. Ambient air is passed through the unit for a period of 5
minutes. The supply fan will then re-start and run at the presetspeed.
The exhaust fan 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).
3.Defrost/Recirculation Mode (5 port “R” models)
The automatic defrost cycle for SHR R(D) / VHR R models of HRVs
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 fan shuts down, the supply fan 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).
2. Intermittent / Standby Mode (SHR(D) / VHR Series of HRVs)
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).

experiment with various
settings until you find a level
that is comfortable for you.
Adjust the control when
needed.
• A dehumidistat is ideal for
use in energy efficient
houses where indoor
humidity (during the
heating season) is higher
than outdoor levels. High
humidity is a major cause
of structure damage and
IAQ problems such as mold
and mildew.

Maintenance
MAKE SURE UNIT IS UNPLUGGED BEFORE ATTEMPTING ANY MAINTENANCE WORK
The following components should also be inspected regularly and well maintained.
Filters
The lters (2) need to be checked and cleaned every
three months or when they appear dirty. Wash in
warm sudsy water (mild detergent) or use a soft
brush vacuum. The lters should be replaced when
they can no longer be cleaned properly.
Heat recovery core
The heat recovery core needs to be checked and cleaned every six months. The core can be cleaned
using a mild soap and water. Rinse thoroughly. Handle with care. Hot water and a strong detergent
will damage the heat recovery core. It is recommended to clean the core in the summer or when the
temperature is mild. Never clean in the heat recovery core in the winter.
Clean Core and Filters Every 3-6 Months.
Unplug unit before doing any repairs or maintenance
a) Open access door.
b) Carefully grip handle of core and pull out. Core will slide out of the channel.
c) Once removed from the cabinet remove lters.
d) Wash core in warm soapy water (do not use dishwasher).
e) Install clean core by:
a) First mounting the bottom ange of the core guide into the bottom channel approximately
1/4” (6mm).
b) Mount the left or right side ange of the core guide approximately 1/4 “ (6mm) followed
by the other side.
c) Mount the top ange of the core guide into the top channel approximately 1/4” (6mm).
d) With all four corners in place and the core straight and even, push hard in the centre of
the core until the core stops on the back of the cabinet.
f) Install the clean lters.

Troubleshooting
Problem Causes Solutions
Air is too dry Dehumidistat control is set too low Increase the desired level of humidity. Change ventilation mode from
continuous mode to standby.
HRV out of balance Have contractor balance HRV airows
Air is too humid Dehumidistat control is set too high Reduce the desired level of humidity. Combine this with the use of continuous
exchange mode.
Sudden change in temperature Wait until outside temperature stabilizes (winter). Heating will also improve
situation.
Storing too much wood for heating Store a majority of your wood outside. Even dried, a cord of wood contains
more than 20 gallons of water.
Dryer vent exhaust is inside home Make sure the dryer vent is exhausting outside.
Poor air circulation near windows Open curtains or blinds.
HRV out of balance Have contractor balance HRV airows
Well sealed basement door is closed Open the door or install a grill on the door.
Failed damper system may be stuck in recirculation
mode
Check defrost damper. If damper is always blocking incoming fresh air, have
contractor verify damper system.
Persistent condensation
on window
Improper adjustment of dehumidistat control Reduce the desired level of humidity. Combine this step with use of continuous
exchange mode.
HRV out of balance Have contractor balance HRV
Poor air circulation near windows Open curtains or blinds.
Poor Air Flows 1/4" (6mm) mesh on the outside hoods is plugged Clean exterior hoods or vents
Filters plugged Remove and clean lter
Core obstructed Remove and clean core
Indoor grilles closed or blocked Check and open grilles
Inadequate power supply at site Have electrician check supply voltage
Ductwork is restricting airow Check duct installation
Improper speed control setting Increase the speed of the HRV (i.e. change unit control from REDUCED to NORMAL
speed)
HRV airow improperly balanced Have contractor balance HRV airows
Ducting has fallen down or been disconnected from HRV Have contractor reconnect ducting
Supply air feels cold Poor location of supply grilles, the airow may irritate
the occupant
Locate the grilles high on the walls or under the baseboards, install ceiling
mounted diffuser or grilles so as not to directly spill the supply air on the
occupant (eg. Over a sofa)
Turn down the HRV supply speed. A small duct heater (1kw) could be used to
temper the supply air
Placement of furniture or closed doors is restricting the movement of air in
the home
Outdoor temperature extremely cold If supply air is ducted into furnace return, the furnace fan may need to run
continuously to distribute ventilation air comfortably
HRV and/or Ducts frosting up HRV air ows are improperly balanced Have HVAC contractor balance the HRV airows
Malfunction of the HRV defrost system Note: minimal frost build-up is expected on cores before unit initiates defrost
cycle functions
Condensation or Ice Build Up in
Insulated Duct to the Outside
Incomplete vapor barrier around insulated duct Tape and seal all joints
A hole or tear in outer duct covering Tape any holes or tears made in the outer duct covering
Ensure that the vapor barrier is completely sealed.
