3.6.Trial running
After installing the multi-functional flow control valve on the resin tank
with the connected pipes, as well as setting up the relevant parameter,
please conduct the trail running as follows:
A. Close the inlet valve B & C, and open the bypass valve A. After cleaning
the foreign materials in the pipe, close the bypass valve A. (As Figure 2
shows)
B. Fill the brine tank with the planned amount of water and adjust the air
check valve. Then add solid salt to the tank and dissolve the salt as much
as possible.
C. Switch on power. Press and go in the Backwash position; when
light on, slowly open the inlet valve B to 1/4 position, making the water
flow into the resin tank; you can hear the sound of air-out from the drain
pipeline. After all air is out of pipeline, then open inlet valve B completely
and clean the foreign materials in the resin tank until the outlet water is
clean. It will take 8～10 minutes to finish the whole process.
D. Press , turning the position from Backwash to Brine& Slow Rinse;
light on and enter in the process of Brine& Slow Rinse. The air check valve
close when control valve finished sucking brine, then slow rinse start to
work. It is about 60～65minutes for whole process.
E. Press to Brine refill position. light on and it indicates the brine
tank is being refilled with water to the required level. It takes about 5～
6minutes, then add solid salt to the brine tank.
F. Press , turning to Fast Rinse position. light on and start to fast
rinse. After 10～15minutes, take our some outlet water for testing: if the
water hardness reach the requirement, and the chloridion in the water is
almost the same compared with the inlet water, then go to the next step.
G. Press , making the control valve return to Service Status; light on
and start to running.
Note:
When the control valve enter into the regeneration status, all
program can be finished automatically according to the setting time;
if you want one of steps terminated early, you can press .
If water inflow too fast, the media in tank will be damaged. When
water inflow slowly, there is a sound of air emptying from drain
pipeline.
After changing resin, please empty air in the resin according to the
above Step C.
In the process of trial running, please check the water situation in
all position, ensuring there are no resin leakage.
The time for Backwash, Brine& Slow Rinse, Brine Refill and Fast
Rinse position can be set and executed according to the calculation
in the formula or suggestions from the control valve suppliers.
