About this file
This is an Installation, Operation and Maintenance Manual for Carnes electronically controlled steam humidifiers, Design Series "E," along with a Unit Nomenclature specification guide. The document provides comprehensive technical specifications for steam humidifier models ranging from 5 to 200 pounds per hour (Lb/Hr) output capacity.
The manual details installation requirements including unpacking procedures, mounting specifications with maximum operating weights ranging from 80 to 185 pounds depending on model, water supply connections using ordinary tap water at 20-120 psi, and drain line configurations. Key installation elements include proper ductwork placement with minimum clearances (6 feet minimum, 14 inches minimum from cabinet to distributor pipe, 16 inches minimum from cabinet bottom to floor), steam distributor pipe mounting on plumb surfaces, and condensate return line management. Electrical specifications cover voltage options from 115V single-phase through 575V three-phase with detailed power requirements, circuit breaker recommendations, and maximum line amperage ratings. The nomenclature guide defines model selection codes including cabinet type (stainless steel with or without breakers), unit type (single or dual steam cylinders), voltage configurations, nominal steam output capacity, agency listings (UL/cUL), and communication protocol options (BACnet MS/TP, Modbus RTU, Metasys M2, Siemens FLN). Operation sections cover startup procedures, steam output rate adjustment, automatic drain cycles, and low conductivity water operation. Maintenance guidance includes routine visual inspection at two-week intervals, water strainer cleaning procedures, cylinder replacement instructions, and troubleshooting protocols addressing common issues such as water in duct, arcing/sparking, continuous draining, and fill failures. Cylinder life averages 1150 hours at maximum output with 150 ppm water hardness, with correction factors provided for varying water hardness levels and operating percentages.

*NOTE: AN EXTERNAL FUSED DISCONNECT SWITCH, OR OTHER SIMILAR PROTECTION, AS REQUIRED BY LOCAL, AND NATIONAL ELECTRICAL CODES MUST BE SUPPLIED AND INSTALLED BY OTHERS. An optional circuit breaker (except for select models over 48 amps) is available in the unit to reduce the risk of costly damage in the event of internal failure. It is not meant to be the primary protection as may be required by local and national electrical codes. All units include electronic overload protection as a standard feature.
q UNIT VOLTAGE CHARACTERISTICS Humidifiers may be ordered with the voltage nameplate ratings shown below. The units may be operated at nominal system voltage shown in Table 6.
Table 7 q CYLINDER LIFE Cylinders have an average life of 1150 hours when operating at maximum output with a water supply hardness of 150 ppm. Approximate cylinder life for other water hardness may be determined by multiplying 1150 by the correction factor shown in Table 7.
Table 8
Cylinder life will be extended if operated at less than maximum output. Multiply the cylinder life calculated in Table 7 by the correction factory shown in Table 8.
