Does my exhaust fan always need to be installed in the ceiling?

MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE SERVICING THE UNIT. Clean your exhaust fan's grill with a mild detergent, such as dishwashing liquid, and dry with a soft cloth. NEVER USE ANY ABRASIVE PADS OR SCOURING POWDERS. Completely dry before restoring power. NEVER IMMERSE ELECTRICAL PARTS IN WATER. The fan assembly can be vacuumed when build up (dirt, lint, etc.) accumulates over time.

A sone is an internationally recognized unit of loudness. The sones translate laboratory decibel readings into numbers that correspond to the way people sense loudness. Double the sone is double the loudness. In everyday terms, one sone is equivalent to the sound of a quiet running refrigerator in a quiet kitchen. The lower the sone, the quieter the exhaust fan is.

When the exhaust fan ventilates air out of the room, the amount of air ventilated needs to be replaced, this is called make-up air. If there is not enough make up air, the exhaust fan's performance will be diminished. Typically make up air for bathroom exhaust fan's is accomplished by a gap cut at the bottom of the door entering into the bathroom.

This is probably attributed to one of the following:1. The motor is loose - turn off power to the unit, remove the grill and check that all screws are fully tightend around the motor. 2. The fan blade is hitting the housing of the unit - turn off power to the unit, remove the grill and check that the blade is fully inserted on the motor shaft.
