HOW TO INSTALL THE REPLACEMENT CYLINDER

1.Reverse procedure should be followed to install new cylinder. Main disconnect is to be left open until cylinder is completely installed and reconnected.

2.Ensure that the re-usable cable tie and mounting brackets, within the unit, secure the cylinder properly.

3.The cylinder plug wires are colour-coded in accordance with coloured dots beside the electrode pins on top of the cylinder.

4.This colour coding must be adhered to when replacing cylinder plugs on pins.

5.With cylinders having six primary voltage cylinder plugs, it should be noted that there are two of each colour.

6.Care must be taken so that cylinder leads of the same color are always directly opposite each other as indicated by the dot formation on the top of the cylinder.

7.The white cylinder plug on all units is for the high water sensor electrode, which always goes on the single pin surrounded by a plastic shoulder.

8.Ensure that cylinder plugs fit snugly on the pins.

9.If cylinder plugs become loose, it is best to obtain a new replacement plug. Consult factory.

EXTENDED SHUTDOWN:

1.Before disconnecting power to the humidifier for a period of extended shutdown, ALWAYS DRAIN the cylinder first.

2.‘Open’ the main external fused disconnect to stop power to the humidifier.

3.Close the shut-off valve in the water supply line feeding the humidifier.

ACCESS SHOULD BE LIMITED TO AUTHORIZED PERSONNEL ONLY.

4.NHTC 3 day drain: As long as the NHTC is powered, it will automatically drain the cylinder when there has not been a call for humidity for an extended period of time.

5.The cylinder will remain empty until there is a call for humidity at which time the fill valve will open and refill the cylinder.

This feature will reduce the possibility of corrosion of the electrodes and the possible accumulation of algae and bacteria growing in the cylinder.
