5.When both the yellow and the green status lamps are on, the water level is detected as being at the top of the cylinder. This is normal on start-up, but as the contained water concentrates, the water will stabilize at a lower water level and the yellow lamp will be off.

6.When the cylinder is fully used, the water level will have returned to the top of the cylinder. Since there is no longer any clean electrode surface available at end-of-cylinder-life, the required steam output rate can no longer be maintained.

7.At this stage, the yellow lamp flashes and the green lamp is on, telling the user that the cylinder is reaching the end of its life and will need to be replaced shortly. The humidifier continues to operate.

8.The NHB relay for remote indication is not intended to indicate end-of-cylinder-life. It is intended to indicate other detected faults explained later in this manual.

9.The NHP at end of cylinder life will not operate, the yellow lamp will “flash”, and the green lamp will be “off”.

HOW TO REMOVE THE STEAM CYLINDER

1.(It is advisable to keep a spare cylinder in stock throughout the humidification season.) When ordering a replacement steam cylinder, always quote the three or five digit model number on the label applied to the cylinder or quote the unit’s serial number, model and voltage located on the spec label (nameplate).

2.Turn off water supply to unit.

3.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 less than 10 minutes).

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

5.Once drained, open the main electrical disconnect during the entire cylinder change operation.

6.Open plumbing door.

7.Cylinder plugs are attached to the primary voltage cylinder wires. (The plugs remain attached to the wires unless they have to be replaced due to damage.) The plugs are press-fitted over the electrode pins protruding from the top of the cylinder. Remove cylinder plugs from cylinder by pulling vertically.

8.Using slot screwdriver, loosen the steam hose clamp(s) and pull steam hose off the cylinder vertically.

9.Using a small slotted screwdriver, depress tab on the re-usable tie wrap, if present, around the middle of the cylinder. This will loosen the tie wrap to come apart for re-use later on.

10.Cylinder is now ready to be lifted out of the unit. CAUTION: Cylinder and any undrained water might still be HOT.

MANDATORY CLEANING OF THE DRAIN

VALVE

Always clean the drain valve before installing a new cylinder since the valve port may be as dirty as the used cylinder.

1.Remove 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.

2.Note that ring terminal for drain valve green ground wire is sandwiched between drain valve body and drain pan.

3.Remove two screws securing drain valve body to drain pan. Disconnect the two slip-on terminals from the two tabs on the (24VAC) drain valve coil.

4.Remove hose clip and hose connection from drain valve body.

5.Drain valve assembly is now free to be taken to a sink for disassembly and cleaning.
