TO REDUCE OR AVOID THE HAZARDS OF ELECTRIC SHOCK AND FIRE:
CAUTIONS CONCERNING THE OPERATION AND FULL EFFICIENCY OF THIS PRODUCT:
CAUTION:
Do not install in a cooking area or connect directly to any appliance. Turn off all integral disconnects before servicing.
NOTICE:
Prior to installing, serious consideration must be taken to insure this ventilation system will operate properly if integrated to any other type
of mechanical system, i.e. a forced air system, or an air handling unit. To insure proper operation & compatibilities of both system, it is required that the
airflow’s of the Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV) be balanced, by following the procedures found in this manual.
The way that your Heat/Energy-recovery ventilator is installed may make a significant difference to the electrical energy that you will use. To
minimize the electricity use of the Heat/Energy-recovery ventilator, a stand-alone fully ducted installation is recommended. If you choose a
simplified installation that operates your furnace airhandler for room-to-room ventilation, an electrically efficient furnace that has an electronically
commutated (EC) variable speed blower motor will minimize your electrical energy consumption and operating cost.
LIMITATIONS:
The product is for residential applications only. Must be installed in accordance with all national and local regulations, building and
safety codes.
Imperial Air Technologies Inc. is the only manufacturer that offers you a complete range of products designed to improve indoor air quality, and that

• Before servicing or cleaning the HRV system, always remove the
power cord from the AC wall outlet.
• To reduce the hazards of electric shock or fire, do not perform any
service to the HRV system other than those stated in the operating
manual instructions.
• To reduce the risk of electric shock, this ventilation system (HRV/ERV)
comes equipped with a 3-prong plug-in. This plug will fit in a polarized
outlet only one way.
• Do not use ventilation system for outdoor application.
• Do not pull or twist power cord when disconnecting it from the
ventilation system. Grasp the plug firmly, not the cord.
• Do not modify the power plug in any way; if modified, risk of electric
shock fire or even damage to the unit may occur.
• Do not use the ventilation system for removal of flammable fumes,
gases or connect directly to any appliances.
• Use a dedicated AC 120V outlet only.
• Do not obstruct or cover the air intake or air outlet of the ventilation
system.
• Do not modify, repair or disassemble this system. These tasks are to
be performed by authorized serviced personnel only. Fire, electrical
shock and/or bodily injury may occur if these warnings are not
followed.
• To prevent injuries, do not operate the ventilation system, while
servicing or maintaining. There are impeller wheels turning at a very
high speed that must fully stop rotating prior to accessing the inside of
the unit.
• Always assess the operation of the ventilation system on how it may
interact with vented combustion equipment (ie. Gas Furnace, Oil
Furnace, Combustion, Appliances, etc.)
• Do not use for swimming pool/spa applications.
