A. MAINTENANCE

WARNING

DISCONNECT MAIN POWER BEFORE ANY SERVICING.

WARNING

THE PLUMBING AND ELECTRICAL COMPARTMENTS CONTAIN HIGH

VOLTAGE COMPONENTS AND WIRING. ACCESS SHOULD BE

LIMITED TO AUTHORIZED PERSONNEL ONLY.

(1)The NHTC and its components are a very low maintenance system. The only maintenance normally required is to change the cylinder, clean out the drain valve assembly, clean out the inlet valve screen and know the procedure for extended shut- down and start-up.

B.WHEN TO REPLACE THE STEAM CYLINDER

(1)The steam cylinder is disposable and must be replaced at end of cylinder life. Cylinder life is dependent on water supply conditions and humidifier usage. Failure to replace the cylinder at the end of cylinder life will cause the unit to lock out. NORTEC is not responsible for any damages resulting from, or attributed to, the failure to replace a spent cylinder (see Manufacturer’s Warranty). There are many indications, each of which signifies the end of cylinder life. See 10-20 Operation, Table 4, for details on how the unit functions and determines end of cylinder life.

C.EXTENDED SHUT-DOWN

(1)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. This feature will reduce or prevent the possibility of corrosion of the electrodes and the accumulation of algae and bacteria growing in the cylinder. The cylinder will remain empty until there is a call for humidity at which time the fill valve will open and refill the cylinder. The unit will go through its normal process for optimum operation.

(2)Should it be required to disconnect power to the humidifier for a period of extended shut-down, always drain the cylinder first. Leave the switch in the OFF position and ‘open’ the main external fused disconnect to stop power to the humidifier. Close the shut-off valve in the water supply line feeding the humidifier.
