Certian units come equipped with a vent cap assembly, this gets installed on top of the unit as shown here. If your unit does not come equipped with this feature call the Lang parts department at 1-800-438-5264 to inquire.

This vent allows:

heat to escape from the electronic controls and motor assemlby more freely, allowing cooler air to enter through the side.

reduces the possiblitiy of blocking the vent or having objects or moisture falling into the controls & motor compartment possibly damaging sensitive electronic components.

Install Vent Cap

1. Unit should be turned off.

2. Align vent ange with mounting holes on top of the unit as shown here.

3. Secure in place with hardware provided.
