• 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 or clothes dryer is venng in basement

• Vibraon or noise • Verify that the correct mounng equipment (vibraon mounng straps, hanging chains or

wall bracket) was used when hanging 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

• 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.
