Question: Does this fan come with it's own power supply from this seller? If not, how did you get power to it?
Document: Awesome dryer fan booster for applications where you have a vent pipe going through the roof. It needs the extra power to prevent it from being clogged up. My client (an architect) was very happy.
All in all, the AC power connection is poorly designed in this unit even if you are using NM-B. Also, it would be helpful if they just put an arrow marking on the fan indicating the direction of airflow.
I wired a grounded pigtail to the unit so I did not have to hard wire the unit, just plugged it in to an available outlet. Make sure you read the instructions to get the unit properly spaced from the dryer, I have had people tell me that they installed a fan unit like this too close to the dryer and they have had problems... follow the instructions and it will work great. Make sure you need a boost fan and that your dryers heat element is not going bad.
At this price, they can't give me two clamps? I found two old clamps in the junk box in the garage and attached the dryer hoses.I attached the power cable (again, not supplied) and powered the unit up. Problem - fan runs with the dryer off (yes, the flow switch is vertical per instructions). Instructions tell me how to adjust the flow switch sensitivity.
The fan works as advertised and wasn't very difficult to install, but the support bracket is very flimsy. I built a small frame out of 2x4s to give in more support. Also, the compartment where the AC wire attaches is too small and is poorly designed. The terminal strip works ok for attaching NM-B solid wire; but it does not accommodate connecting an AC power cord (with stranded wire) that is plugged into an outlet.
Our brand new dryer was taking nearly 3 hours to dry an average size load of laundry. We had GE come out to check out the dryer and they told us that the dryer vent run was too long given the size of the dryer. We researched options for boosting the dryer ventilation and chose this fan after reading several customer reviews. This fan has solved all of our dryer issues. Now I can dry a large load of laundry in about 45 minutes. This fan was worth every penny!
So if you are not really equipped for all this, you may want to get a pro to protect your purchase and make it safe, and possibly save you a couple of bucks.
this is the second one the first one we orderd for customer wouldn't shut off talked to tech support they told us to order new one and send other back we are waiting for our customer to get back from vacation to install replacement well let you no tks
I've oriented the switch as directed and followed every instruction. I suspect its that the housing is misformed around the sensor so the static pressure won't get high enough. I've invested 4 hours with this project and I am now sending back my second piece of substandard equipment.
Unfortunately, it didn't seem to give us the drastic drying time increase we were expecting, so then we hired a company to come out and clean the exhaust line and that is when we discovered two things. First, the line was clogged with all sorts of lint from years of use without being cleaned, and second, the dryer line was pushing 40 FEET LONG!!
