FAQ
Q: What is the difference between the duplex parallel configuration and a single tank softener?
A: The CES-2900E-120-DP duplex parallel system features two mineral tanks that work in alternating cycles. When one tank regenerates, the other continues providing soft water, ensuring uninterrupted service and higher continuous flow rates ideal for 24/7 commercial operations.
Q: How often does the brine tank need to be refilled with salt?
A: Refill frequency depends on water hardness and usage volume. With a 750-pound salt storage capacity and consumption of 36 pounds per regeneration cycle, the system can handle approximately 20 regeneration cycles before requiring refill, typically ranging from several weeks to months in most commercial applications.
Q: What are the electrical and plumbing requirements for installation?
A: The system requires 115 VAC/60 Hz/1 Phase electrical connection, 2-inch MNPT inlet and FNPT outlet connections, operating water pressure between 25-125 psi, water temperature of 40-100°F, and adequate drain line installation with proper air-gap maintained per local plumbing codes.
