Location - Installation Notes
Install the unit in a conditioned 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.
If attic installation is necessary the unit must be situated in a conditioned space with access to service.
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.

Pre-Installation Notes
Read this notice before installing unit:
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
ERV, 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.
Do not install control wiring alongside electrical wire.
Caution
Due to ongoing research and product development, specifications, ratings, and dimensions are subject to change
without notice. Refer to www.LIFEBREATH.com for the latest product information.
The plugs found in the manual bag, must be installed at the base of the 130ERV and 130ERV-R models before
the unit is operated. Refer to page 19 of this manual.

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 ERV. 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
ERV port and the weatherhood prior to clamping.
The flexible insulated duct that connects the two outside weatherhoods to the ERV should be stretched
tightly and be as short as possible to minimize air flow restrictions.
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 local building code.

Selecting the Ventilation Rate That is Right for You
The modes of operation and speeds are used to adjust your indoor ventilation rate. Experiment with the
ventilation levels in your home to evaluate the ideal amount of ventilation to suit your home and
personal preferences. Operational modes available to you will depend on the main control that is installed.
Come features and modes may be unavailable to you.
Recirculation
Recirculates existing household air without introducing fresh air. Recirculation modes (II and V) are not
applicable if your ERV is connected to a forced air system, since your forced air system already circulates the
household air. Recirculation modes are unavailable on some models.
I. Continuous Ventilation
This mode of operation provides continuous ventilation within the home. You may, for example, select
Continuous Ventilation at low speed for normal operation and increase to high speed during increased
activity levels, such as cooking and showering, etc.
II. 20 Minutes On, 40 Minutes Recirculation 20/hr 40/hr
This mode ventilates for 20 minutes and recirculates the household air every 40 minutes each hour. This
mode is not applicable if your ERV is connected to a forced air system.
III.20 Minutes On, 40 Minutes Standby 20/hr 40/hr
This mode of operation provides 20 minutes of ventilation each hour. You can use this ventilation mode at
low speed for low household activity levels or when the home is unoccupied.
IV. 10 Minutes On, 50 Minutes Standby 10/hr 50/hr
This mode of operation provides 10 minutes of ventilation each hour. You can use this ventilation mode at
low speed for low household activity levels or when the home is unoccupied. This mode is useful when
20/40 mode is providing too much ventilation.
V. Continuous Recirculation or
This mode continuously recirculates your household air (no ventilation). This mode is not applicable if your
ERV is connected to a forced air system.
VI. Continuous Low Fan Speed LO
This mode will operate the fan in low speed continuously at the selected operating mode (Ventilation or
Recirculation).
VII. Continuous High Fan Speed HI
This mode will operate the fan in high speed continuously at the selected operating mode (Ventilation or
Recirculation). This mode is useful when occupancy in the home or activity is high for an extended period
of time.

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 ERV by the end user may occur if the unit is
modified from “fully-off” to “standby-off”.
Attention/Caution
17
The ERV will be “fully-off” when the off position is selected
on the Main Control. Timers and/or other controls will not function when the ERV 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 ERV With Dry Contact Controls
A jumper must be in place between 2 (ON) and 3 (RED) on the terminal block to activate the ERV 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)
Installer Selectable High Speed Settings
The circuit board on this unit has adjustable DIP switches for the selection of HIGH speed Hi1, Hi2 or
Hi3. The factory setting is Hi3, which is the highest speed possible H2 will result in a lower airflow
than H3, with H2 the lower of the high speeds. Refer to the specification page found online at;
www.lifebreath.com for the airflow rates on Hi1, Hi2 and Hi3.
Note: Low speed is not adjustable.
