OREiN OL17001-NA-1 Bathroom Exhaust Fan with Light

Question 1: How to adjust the ceiling hole

Answer:

①Hold the housing up to the hole to check that your fan fits. If the hole is too small, trace the housing onto the ceiling and then cut the ceiling with a keyhole saw.
②If the hole is too big, you’ll need to patch the ceiling. Cut a piece of drywall to make the ceiling hole the right size for your fan. Attach the drywall filler to a larger piece of wood; set it in the hole and drive screws through the ceiling into the wood. The patched areas can be repaired with spackling compound later.

Question 2: The light does not work.

Answer:
① Make sure you are using a non-dimmer switch and that the switch contact is good.
② Make sure that the cables to the light and fan are properly connected. And this product only works with 120V.
③ Make sure the wire connecting the lampshade to the housing is well inserted.
④ If that’s still not helpful, please contact Customer Service, OREiN will provide after-sales service

Question 3: The fan seems louder than it should.

Answer:

①CFM too great. Be sure the CFM rating on the fan matches the size of your room.
②Damper not working properly or damaged. Check damper to ensure it is opening and closing properly. If the damper has become damaged, please contact Customer Service.
③Bend in duct too close to fan discharge. Be sure you do not have any sharp bends in duct closer than 18 in. to the fan discharge.
④Fan discharge reduced to fit smaller duct. Use recommended size ducting to reduce fan noise.
⑤Fan housing not securely attached. Be sure the fan is securely attached to your ceiling joists.

Question 4: How to prevent moisture buildup?

Answer:

①If you have access to the attic, then you can vent a ceiling mounted exhaust fan through either a gable wall or the roof. Letting the fan exhaust into an open attic will cause moisture buildup on the underside of the roof. Avoid venting through a soffit vent or ridge vent. The warm air will exhaust out the duct and enter back into the attic through the soffit vent or ridge vent.
②An insulated duct will help prevent condensation when the warm air from the bathroom meets the cold duct in the attic.

Question 5: The fan is not clearing the room.

Answer:

① Make sure the fan you choose is powerful enough to ventilate your bathroom. The room’s size determines the necessary cubic feet per minute (CFM) rating of the fan. The CFM rating measures the volume of air the fan moves. As a general rule, you’ll need at least 1 CFM per square foot of space. A fan that’s too small won’t remove moisture and odors efficiently and will need to run longer, increasing wear on the motor.
② Be sure a door or window is slightly ajar or opened to allow airflow. The fan is not able to draw air out of the room without enough airflow to draw from.
③ The deep corrugations of flexible ducting can easily flex into the opening and block the damper. Please use semi-rigid ducting, which is made of aluminum and has very shallow corrugations that allow you to flex it or stretch it.
④ Make sure the bathroom fan you choose is ducted properly. Fans should be vented to the outside, not to the attic or crawlspace. If the duct work isn’t accessible through the attic, vent the fan through an outside wall of the house. Be sure the fan is vented with the right size duct. Let the exhaust fan run for 20 minutes after someone showers to ensure the proper amount of ventilation.

Question 6: The bath fan has 3 to 4 seconds delay after I turn it on. Is

it normal?

Answer:

Our bath fans all have slow start and slow stop mechanisms, this is to better protect the motor. Just like a car, it takes time to reach the top speed. The faster the motor will age if it is started too fast.
