F79 Residential Water Softener Valves

Featuring a flow rate of 2m³/h, the F79 achieves different functions, including service, backwash, brine& slow rinse, brine refill and fast rinse through parameter modifications.

The F79 is a multifunctional softening valve, where up-flow regeneration, down-flow regeneration are all accomplished. The F79 is also furnished with an F70D bypass valve, allowing for original water passage during the regeneration process.

Product Characteristics

• Simple structure and reliable sealing

  It adopts hermetic head faces with high degree pottery and corrosion resistance for opening and closing. It combines with Service, Backwash, Brine & Slow Rinse, Brine Refill and Fast Rinse.

• Manual function

  Realize regeneration immediately by pushing manual button at any time.

• Long outage indicator

  If outage overrides 3days, the time of day indicator “‡” will flash to remind people to reset new time of day. (Refer to the figure)

• LCD screen display

  Adopt wordage to display all status, clear and briefly.

  Users can choose English or Chinese display interface in 2 ways:

  A. Connecting power then press buttons “Menu/Confirm” and “Manual/Return” for five seconds to enter language choice interface.

  B. Enter into “Set Language” to choose the language.

• Buttons lock

  No operations to buttons on the controller within 1 minute, button lock indicator light on which represent buttons are locked. Before operation press and hold the “Up” and “Down” buttons for 5 seconds to unlock. This function can avoid incorrect operation.

• The F79 with weather cover can be installed outside

• Has water bypass and no hard water bypass two choices

  No hard water bypass refers to the control valve no water pass when valve in regeneration. Model: A for no hard water bypass (No raw water flow out from outlet when in regeneration process); B for with hard water bypass. (With raw water flow out from outlet when in regeneration process)

• With partial bypass function

  Service time, by adjusting bypass screw can let part of raw water flow into the outlet without being softened.

• Down-flow regeneration, up-flow regeneration and filter can be implemented with a valve.

  By program selection to choose following modes

• Interval backwash times (Only for up-flow regeneration valve)

  It could set up interval backwash times for up-flow type A-11, 12, 13, which means several times of services but one time of backwash. The setting of interval backwash time is depending on the local water turbidity. (The lower the turbidity is, the longer of the interval backwash time can be set)

• Rinsing frequence

  It could set up rinsing frequence when selection of filter mode A-21, which means several times of backwash and fast rinse but one time of service (Need set). In this mode, the brine line connector need be sucked in this working mode.
