Pre-Installation Notes
Note
•
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.
Attention
•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 the electrical connections. The
recommended circuit is a separate 15 A/120 V circuit.
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 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 back drafting 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.
Warning
•
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.

1LOCATION 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 proximity to where the weather
hoods are mounted. If a basement area is inconvenient or non-existent, install the unit in a utility
room or laundry room.
Leave enough 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. Four
straps are provided with the unit for hanging it from the basement floor joists.
Attic installations are not recommended due to:
•The complexity of work to install
•Difficulty of access for servicing and cleaning
•Freezing conditions in the attic
If attic installation is necessary, the unit must be situated in a conditioned space.

7DRAIN CONNECTION
The ERV cabinet has pre-punched holes for the drain. The ERV may produce some condensation
during a defrost cycle. This water should flow into a nearby drain or be taken away by a condensate
pump.
Figure Callouts:
(1) Drain Spout
(2) Drain Pan
(3) Drain Spout Nut
(4) Tee Connector
(5) 1/2 in. Drain Hose
(6) Drain Line
(7) Zip Tie
Installation Steps:
1. Insert the drain spout through the hole in the drain pan.
2. Install nut and washer on the drain spout.
3. Construct a P-trap using the plastic tee connector. Tighten the nut.
4. Cut two lengths of 1/2 in. drain hose (not included) and connect the ends to the two drain spouts and
the other ends to the plastic tee connector.
5. Position the tee connector to point upward and connect the drain line. Use a zip tie to secure the drain
line to one of the 1/2 in. drain hoses.
6. Tape or fasten base to avoid any kinks.
7. Pour a cup of water into the drain pan of the ERV after the drain connection is complete. This creates a
water seal which will prevent odours from being drawn up the hose and into the fresh air supply of the
ERV.
Caution
•
A drain is required. However, the climates where the outdoor temperature remains above -25°C
(-13°F) combined with an indoor humidity less than 30%, the use of a drain is optional.
•The ERV and all condensate lines must be installed in a space where the temperature is
maintained above the freezing point or freeze protection must be provided.
