All specifications are subject to change without notice. Installation, maintenance, operating, and any other instructions furnished with the equipment must be carefully followed by installers, owners, and users.
Shipping Models CEJW series: The unit must be laid down for shipment requiring some disassembly. Valves, trim, water level controller, electrodes, and actuator will be removed for shipping and require field installation. The unit may then be field-connected to feedwater, electric power, and the control panel.
Water Treatment: All boilers require adequate water quality as determined by conductivity, pH, softness, and chemical content. The type and degree of water treatment will be determined by local water quality, type of boiler, nature of operation, and quantity of raw makeup water required. It should be noted that the conductivity of the boiler water, alkalinity, pH, and chemical content increases as steam is generated. Most water supply systems are suitable for use with ACME Electrode Boilers when supplied with proper water treatment. A complete water analysis must be furnished to ACME for review to ensure proper water quality.
