cylinder or quote the unit’s serial number, model and voltage located on the spec label (nameplate).

2.The used cylinder must be drained completely before removal. If the water has just been boiling, allow it to cool before draining. Push the ON/OFF/DRAIN switch to the MANUAL DRAIN position. Leave it in this position just long enough to drain the cylinder (usually not longer than 3 minutes).

3.When completely drained, push the main ON/OFF/DRAIN switch back to the OFF position.

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.

9.Remove the used cylinder as previously described. NORTEC does not recommend the use of any acid solutions to clean the used cylinder. Always replace a used cylinder.

HOW TO INSTALL THE REPLACEMENT CYLINDER

1.Reverse procedure should be followed to install a new cylinder. Main power supply to the unit must be disconnected until the cylinder is completely installed and reconnected.

2.The cylinder plug wires are color-coded in accordance with colored dots beside the electrode pins on the top of the cylinder.
