IMPORTANT -
PLEASE READ THIS MANUAL
BEFORE INSTALLING UNIT.
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 air flows 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.
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 enure the proper grounding of the unit.
• Do not apply electrical power to the unit until after
the completion of the installation (including the
installation of low voltage control wiring).
• Ensure the Installation and wiring is in
accordance with CEC, NEC, and local electrical
codes.
• Due to ongoing research and product
development, specifications, ratings and
dimensions are subject to change without notice.
•
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 amp/120 volt circuit.
• Due to ongoing research and product
development, specifications, ratings and
dimensions are subject to change without notice.
