4.Once drained, disconnect all power supplies to the unit.
5.Open the front cover door.
6.Cylinder plugs are attached to the primary voltage cylinder wires. Remove cylinder plugs from cylinder pins by pulling vertically.
7.Using a slotted screwdriver, loosen the steam hose clamp(s) and pull the steam hose off the cylinder vertically.
8.The cylinder is now ready to be lifted out of the unit. CAUTION: Cylinder and any undrained water might still be HOT.
