INSTALLATION
RECEIVING EQUIPMENT
1.Check packing slip to ensure ALL material has been received.
2.Inspect box for damage and note on shipping waybill accordingly.
3.After unpacking, inspect unit for damage and if damage is found, advise shipper as soon as possible.
4.Inspect unit (humidifier) to ensure it is the correct model, phase, and voltage. If any are incorrect, advise the factory or your local representative immediately.
NOTE: All products are shipped on an F.O.B. factory basis. Any and all damage, loss, or breakage claims are to be made directly to the shipping company.
The NORTEC
FOR HUMIDIFIERS INSTALLED IN THE CITY OF LOS ANGELES: A city of Los Angeles approved
Recommended valve manufacturer: Watts Regulator (phone
Each drain line from these humidifiers shall be routed, without dips or sags, to terminate above the flood level rim of a City of Los Angeles approved indirect waste receptor.
No combustible materials shall be placed in the duct and/or the air plenum.
PRINCIPAL OF OPERATION
When the humidistat calls, the cylinder fills to 100% of the Full Load Amperage (F.L.A.) or to the top of the cylinder, whichever comes first. See Figure #1.
If it reaches 100% F.L.A. the water heats and boils away to a level giving 80% F.L.A.

An electronic timer uses the rate of amp fall to determine the water level. The objective is to concentrate
This achieves the longest life for the disposable cylinder because of minimal electrode coverage and use of less energy because the high concentration allows a minimal drain rate.
When 80% F.L.A. is reached, the fill valve will open refilling cylinder to 100% F.L.A. On occasion, the drain valve will also come on if water level is too low, indicating too high a concentration and the requirement for a dilution of the water in the cylinder.
If the water reaches top of cylinder before 100% F.L.A., the fill valve shuts off via the sensor and
