Using this clothes dryer vent kit is simple. First, make sure your dryer has a 100mm flue vent outlet. Then, connect the included 100mm X 1.3m vent hose to the dryer. If you're using it with a Fisher & Paykel rear - vented model, it fits directly, but for wall - mounted setups, you'll need a vent adaptor. For other dryers, you may need a suitable dryer flange kit. The kit allows the moist air from the dryer to be condensed into a container. Just empty the container regularly to keep it working well. As for maintenance, clean the lint and fluff caught by the kit often. This will ensure that it continues to condense moisture effectively and keep your laundry area clean. When using a wall - mounted setup, remember that a vent deflector adaptor (not included) is usually required.
