Location - Installation Notes
Install the unit in a heated space that provides clearance for service access. A typical location is in
either a mechanical room or an area close to the outside wall within close proximity to where the
weatherhoods are mounted. If a basement area is inconvenient or non-existent, install the unit in a
utility room or laundry room. Attic installations are not recommended due to:
The complexity of work to install
Freezing conditions in the attic Difficulty of access for servicing and cleaning
If attic installation is necessary the unit must be situated in a conditioned space.
Leave sufficient clearance at the front of the access door for servicing the air filters and core. The
recommended clearance is a minimum of 25 in (635 mm) for opening and closing the door. Airia
provides four straps for hanging the unit from the basement floor joists.

Pre-Installation Notes
Read this notice before installing unit:
3
Disconnect the power from the unit before cleaning or servicing
To prevent electrical shock, it is extremely important to confirm the polarity of the power line that is switched by the
safety (disconnect) switch. The hot line (black) is the proper line for switching. Use either a voltmeter or test lamp
to confirm the absence of a voltage between the disconnect switch and ground (on the cabinet) while the door is
open. This procedure must be followed, as dwellings are occasionally wired improperly. Always ensure the proper
grounding of the unit.
Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal injury or
loss of life. Installation and service must be performed by a qualified installer or service agency.
Warning
Do not apply electrical power to the unit until after the completion of the installation (including installation of low
voltage control wiring).
Ensure the installation and wiring is in accordance with CEC, NEC, and local electrical codes.
Plug the unit into a standard designated (120 VAC) electrical outlet with ground.
The use of an extension cord with this unit is not recommended. If the installation requires further wiring, have a
licensed electrician make all of the electrical connections. The recommended circuit is a separate 15 A/120 V circuit.
Attention
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 pieces of equipment must be confirmed, by measuring the airflows of the
HRV, by using the balancing procedure found in this manual. 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.
Unit must be installed level to ensure proper condensate drainage. Due to the broad range of installation and
operational conditions, consider the possibility of condensation forming on either the unit or connecting ducting.
Objects below the installation may be exposed to condensate.
Caution
Due to ongoing research and product development, specifications, ratings, and dimensions are subject to change
without notice.
Note

Simplified Installation (Return/Return Method)
Installation Notes

Adjustable grilles should be used to balance the flow rates into and out of various rooms. The
grilles should not be adjusted after balancing the unit.
Grilles or diffusers should be positioned high on the wall or in the ceiling. Kitchen exhaust should
never be connected to the range hood. They should be installed at least 4 ft (1.2 m) horizontally
away from the stove.
Field supplied balancing dampers should be installed external to the unit to balance the amount
of stale air being exhausted with the amount of fresh air being brought into the house. Refer to
airflow balancing section.
The Lifebreath Kitchen Grille includes a
removable grease filter. Most building codes
require that kitchen grilles are equipped

Lifebreath Weatherhood
Fixed covered weatherhoods have a built-in bird screen with a 1/4 in (6 mm) mesh to prevent
foreign objects from entering the ductwork.
Installation Notes
The inner and outer liners of the flexible insulated duct must be clamped to the sleeve of the
weatherhoods (as close to the outside as possible) and the appropriate port on the HRV. It is very
important that the fresh air intake line be given special attention to make sure it is well sealed. A
good bead of high quality caulking (preferably acoustical sealant) will seal the inner flexible duct to
both the HRV port and the weatherhood prior to clamping.
The flexible insulated duct that connects the two outside weatherhoods to the HRV should be
stretched tightly and be as short as possible, to minimize airflow restriction.
Twisting or folding the duct will severely restrict airflow.
Hard (rigid) ducting which has been sealed and insulated should be used for runs over 10 ft
(3.3 m). Refer to your building code.

Mechanical Timers Installation 99-101
The Mechanical Timer is a 2 wire “dry
contact” timer. A jumper wire must
be connected between 2 (ON) and
3 (RED). Connect the 2 timer wires
to ON and HI.
Timers mount in standard electrical boxes
Use 3 wire 20 gauge (min.) 100 ft length (max.) low voltage wire and multiple timers individually wired back to the unit.
Caution:
Consideration should be given to competing airflows when connecting the HRV in conjunction with an air handler/
furnace blower system.
Building codes in some areas require “fully-off” functionality. Check with your local building authority before
modifying the unit to “standby-off”. Unintentional operation of the HRV by the end user may occur if the unit is
modified from “fully-off” to “standby-off”.
Attention/Caution
2 wire timers require a
jumper wire between
ON and RED on the
terminal
block Connect the 2
wires from the
timer to ON and HI on the terminal block.
Interlocking the HRV to an Air Handler or Furnace Blower
Connecting the HRV as illustrated will ensure the air
handler/furnace blower motor is operating whenever
the HRV is venting.
The HRV must be interlocked to the furnace/air handler
with a simplified installation (return/return installation)
and should be interlocked with a partially dedicated
installation.

Setting “Standby” When Using a Main Control
The HRV will be “fully-off” when the off position is selected on the main control. Timers and/or oth-
er controls will not function when the HRV is in the off position.
The “fully-off” feature can be modified to “standby-off” by adding a jumper on the terminal block
between 2 (ON) and 3 (RED). “Standby” can also be achieved by setting the main control to the ON
position and selecting speed 0*. Timers and/or additional controls will initiate high speed ventilation
when activated.
*Speed 0 is not available on all controls.
Operating the HRV Without a Main Control and Adding Dry Contact Controls
A jumper must be in place between 2 (ON) and 3 (RED) on the terminal block to activate the HRV for
timers and/or dry contact controls.
Adding Dry Contact Controls
Low Speed: A jumper between 2 (ON) and 1 (LOW) initiates low speed ventilation.
High Speed: A jumper between 2 (ON) and 6 (HI) initiates high speed ventilation.
Dehumidistat: A dry contact for a dehumidistat is connected between 2 (ON) and 10 (BLK)
The HRV must have a jumper in place between 2 (ON) and 3 (RED) on the terminal block when
installing the unit without a main control.
