.  Start manual regeneration of the system. 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 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 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.

3.4. Procedure for installing a DFU Twin or DFK Twin systems

DFU Twin and DFK Twin systems are equipped with two CE control valves, a three-way 
Motorized Alternating Valve, and a communication cable for connecting the control valves. 

The three-way MAV routes water from the filter that is currently in service to the outlet, while 
keeping the reserve filter shut off. Lead filter’s control valve actuates the MAV and controls 
the reserve filter.

Twin systems provide uninterrupted treated water supply without falling back on raw water 
when the system is regenerating.

.  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).

2

.  Put plugs or caps on the top ends of the riser pipes to prevent getting any media inside 

the pipes. Pour the resin in both tanks using the funnel. When loading each tank, keep riser 

pipe vertical. If the pipe tilts, restore it to straight vertical direction. When finished, rinse the 

threads of tank openings with water to remove any beads of media stuck in the grooves.

3

.  Lock the top distributor in circular slot at the bottom of the control valve’s shank. Install 

control valve on the lead tank. Mate the distributor with top end of riser pipe, then screw the 

control valve on. Install the second control valve on the reserve filter tank in the same way.

4

.  Connect drain pipe to the male threaded drain outlet of each control valve. Run the 

drain pipes to floor drain or gravity drain pipe socket. Secure the drain pipe end above the 
receiving fixture with at least 1″ air gap.
