Leveling and door reversal

Leveling the Dryer
Proper leveling is important for performance. The dryer must be level to help provide optimal drying performance. A perfectly level, solid floor helps minimize vibration, noise, and unwanted movement.
Before you begin - Wear long-sleeved gloves and safety glasses. - The appliance is heavy. Two or more people are required for installation. - If the dryer is being installed on the optional pedestal, use the leveling feet on the pedestal to level the appliance. The dryer’s own leveling feet should be fully retracted.

Steam water inlet connection

Connecting the Steam Water Inlet Hose
To use steam, the dryer must be connected to the cold water tap with a new water supply hose. Do not use old hoses.
Before you begin: - Make sure you have a suitable cold water faucet. - Use only new hoses for installation. - If your water supply has a lot of debris, a whole home water filter may help keep debris from reaching the dryer inlet. - Do not install or store the appliance where it may be exposed to freezing temperatures.
