About the ERV/HRV Ventilation System
The ERV/HRV Balanced Ventilation System provides
improved indoor air quality through its high performance
and efficiency.
Benefits
• Ventilation with sensible heat recovery (ERV and HRV)
• Ventilation with latent heat recovery (ERV only)
• Simplified mounting (hanging)
• Optional hanging with included straps.
• Removable duct collars for easy ducting to the unit
• Intuitive balancing via two variable speed motors and
a speed control
• Fits in tight spaces (VNT5070)
CAUTION: Electrical shock and fire hazard. Can cause personal and equipment damage.
• Before servicing or cleaning the system, always remove the power cord from the AC
wall outlet.
• Wear protective clothing and safety glasses when installing ventilator and working
with sheet metal.
• To reduce the hazards of electric shock or fire, do not perform any service to the
system other than those stated in the operating manual instructions.
• To reduce the risk of electric shock, this ventilation system 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 120 VAC outlet only.
• Do not use an extension cord.
• 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 how the operation of the ventilation system may interact with vented
combustion equipment (i.e. Gas Furnace, Oil Furnace, Combustion, Appliances, etc.)
• Ensure unit is properly installed and suspended to prevent falling or dropping injuries.
