.  Remove the front panel of each control valve by pulling the locking tabs on the left and 

right side. Run the power cord through cord guide in each control valve’s backplate and 

connect it to the 12 VAC socket on the circuit board. Connect MAV cord to the lead filter’s 

MAV socket. Connect the lead tank’s circuit board to the reserve tank’s circuit board with the 
3-wire cable by plugging it in the COMM CABLE sockets in each circuit board. Make sure all 
external cables are routed through the guides in control valve backplates, so the front panel 
can be put back on. Plug both power supplies in the mains to power up the system.

.  Enter programming menu and setup both control valves for Twin operation (see 

programming instructions in the next section).

.  Start  manual  regeneration  of  the  lead  filter  by  holding  REGEN  button  for  5  seconds. 

Scroll regeneration to backwash if it isn’t the 1st step of the sequence. When the control 

valve starts the backwash, turn on mains water supply slightly at first. Air will be displaced 
from the system via drain line while the pressure tank is being filled with water. When the 
tank is full, water will start flowing down the drain line. At this point, scroll through the rest of 

the regeneration sequence to end regeneration.

Then start one more manual regeneration (by holding REGEN button of the lead filter) and 

scroll to backwash if it isn’t the 1st step. Wait until all air is displaced from the second tank.
Then scroll through the rest of regeneration sequence to end regeneration.

Fully open mains water supply. Carefully inspect the system for leaks. Manually initiate two 
more complete regenerations, one after another.

3.5. Procedure for installing a DFU Duplex or DFK Duplex systems

DFU Duplex and DFK Duplex systems are equipped with two CE control valves, two No 

Hard Water Bypass Valves, and two microswitches with linking cables. The microswitches 

link each control valve to the other control valve’s microswitch socket. This prevents both 

filters  regenerating  simultaneously  –  if  one  of  the  filters  is  regenerating,  the  other  will  not 
regenerate until the former finishes. No Hard Water Bypass Valves prevent raw water from 
being drawn when any of the filters regenerate.

Duplex systems provide uninterrupted treated water supply with the peak flow capacity of 
both filters online, low flow capacity of one filter online one offline for regeneration.

.  Install both FRP tanks on firm level surface capable of supporting their weight. Put riser 

pipes with bottom distributors down in each pressure tank. Ensure that top ends of riser pipe 
are level with the top openings of the FRP tanks (within ±5 mm).
