Pre-Installation Notes
• 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.
• 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.
• 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
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.
• Pool room air/surfaces must have a heating appliance which does not include the pool water as its
source. The pool room and water must be continuously operated at its original design as any deviation
from this could greatly effect the operation of the unit. The pool unit must be fully commissioned after
installation which includes confirming proper operation of the control, normal operation of the unit, and
drainage through the pans without unintentional leakage.
• 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.
