System start-up
Make sure all topics in the installation part of this manual is resolved before starting the start-up phase. Depending
on our specific setup, you might have additional parts to consider.
Step by step
1.
Make sure all relevant parts for your system is installed and ready, as described in the installation section.
2.
Make sure
system (9) is not turned on at this time.
3.
Close flow regulation valve (7)
4.
Disconnect hose from bottom of mixing tank (4).
a.
Unscrew the ½ inch hose connection to allow water out of the small tank (4).
5.
Open water connection to system (max 85 psi)
6.
Vent dosing units, by pressing button on top of unit (3&5). Hold down the button until the water
flows out in a steady stream.
7.
Prime the dosing unit (3) by running the unit until HCL is socked into the unit body. Dosing unit scale
can be adjusted to allow faster filling of hose and unit.
8.
Adjust dosing unit scale to half way position.
9.
Let dosing unit run and check pH level in mixing tank. Allow adequate time for changes to take effect
after any changes. Mixing tank pH level should be between pH 1 and 1.5 depending upon feed water
pH. The pH level can be adjusted using the scale on dosing unit 1. Moving the ‘Handle” on the scale
up, lowers the pH level in the tank (4).
10.
When desired pH level is reached the hose at the bottom of tank (4) can be reattached.
11.
Let tank (4) fill with water at the correct pH level and make sure the float valve controls the level as
intended.
12.
Adjust scale on dosing unit 5 to 50 % (half way).
13.
There are two different ways to do the next part.
a.
Run system
b.
Disconnect water inlet (8) from system and let the solution run into a bucket for
testing
and then
drain.
For this start up instruction, I have chosen to use option b.
14.
Open flow valve to allow the solution to flow into the bucket.
15.
Let the solution run into the bucket and watch dosing unit 2 suck in the solution from mixing tank (4).
16.
Test the pH level of solution running into the bucket. The pH level at this point should be 1 to 2 pH
below the desired final product. The exact pH level depends on the setting of the system.
17.
The pH level can be adjusted using the scale on the second dosing unit. Adjusting the “handle” up
towards the unit body will lever the pH level of the solution.
18.
When the correct pH level has been reached close the flow valve to stop the flow.
19.
Reattached the hose to the system inlet (8)
20.
Open the flow control valve. The valve can be adjusted to the desired flow rate later on.
The pressure regulator has been adjusted to 45 psi from factory and therefore does not need further adjustments.
