Question / Item Diagnosis / Solution
• Venlator not
running
• Verify breaker in main electrical panel
• Verify the HRV or ERV is in the ON posion
• Verify all wall controls connected to the venlator are acvated to supply power to the unit
• Unplug venlator and verify that the wall control is wired correctly to the connecon box on
the side of the unit
• Verify main outlet polarizaon
• Air is too dry • Increase the humidity level on the wall control (Turn dial towards 60%)
• Reduce connuous airow rate
• Switch venlaon mode from connuous to intermient
• Increase the humidity level in the home by installing a whole-home humidier
• Air too humid • Suggest connuous operaon of venlator
• Reduce humidity seng on the wall control (Turn dial towards 30%)
• Increase connuous airow rate (venlator fan speed)
• Insucient venlaon, check that the capacity of the venlator is sucient
for the size of the home
• Internal source of moisture, e.g. heang wood stove in basement, possible water leaks in
foundaon or poor insulaon R-value and or clothes dryer is venng in basement
• Vibraon or noise • Verify that the correct mounng equipment (wall-mounng bracket) was used when hang-
ing the venlator.
• Verify that a secon of exible duct is installed between the venlator and the rigid duct.
• Verify that the motors are operang properly and the fans are rotang freely and are not
obstructed by any debris
• Cold air • Misplaced supply outlets
• Defrost not operang correctly
• The venlator is not properly balanced
• High airow on furnace connuous mode
• Ensure venlator is interlocked when integrated with forced-air system
• Pollutants • Ensure proper clearance of venlaon hoods from source of pollutants
Refer to secon "Installing Venlaon Hoods for Fresh Air and Exhaust"
• Condensaon • Verify that the venlator is level to ensure proper drainage
• Verify that the duct connecons are secured with screws to the venlator.
• Verify the fresh (supply) side duct connecons are fully insulated and that the home has a
properly-installed vapor barrier to ensure the home is sealed ghtly.
• Look for any secons of crushed ducng, failing duct straps, punctured vapor barrier, or
missing insulaon.
• Look for signs of water accumulaon/leakage/dripping
• Ensure proper seal of vapor barrier to outside wall.
• Verify that the drain connecon is not kinked; i.e. that the “P” trap is not too close to the
venlator or is blocked with debris.
