Step 11: Replace top tank/flange/strainer assembly (removed in Step 1) and tighten. Fit
pipe work supplied and hand tighten each union. Check that main valve and pipe
work is vertical, tighten all unions. Fit air release valve to the Tee at the top of the
pipe work. Check all joints and flanges are tight. Do not overtighten.
Step 12: Remove the lid of the brine tank and remove the brine tube (black poly flexible
tubing). Connect the brine tube to the throttle/stop valve on the main control
valve.
Step 13: Remove the brine valve from the brine well of the brine tank. Ensure brine tank is
free from foreign matter and set brine valve and float height as follows:-
Determine if wet salt or dry salt is required, using the formula
shown in “Determining Frequency of Regeneration”. If sufficient
information is not available to do the calculations shown in
“Determining Frequency of Regeneration”, contact our office. The
brine valve is supplied factory fitted with a dry salt riser, a wet salt
riser is also supplied (short black screwed riser pipe - refer Fig.
19). Store the riser tube not used, DO NOT DISCARD it may be
needed at commissioning.
Step 14: Replace the brine valve in the brine well and connect brine tube - this tube is
supplied long and can be cut to the desired length.
Step 15: Now add the No 4 gravel to the brine tank (120kg - 6 bags) and level. Ensure no
gravel enters brine well - add salt to the tank (refer Table 7 for correct quantity),
replace lid.
Step 16: Plumb the unit, noting the following:-
a)
Check arrow markings on the valve for correct inlet/outlet plumbing (Fig.1).
b) Use minimum 50mm pipe size.
c)
Fit a pipe union to drain line for ease of access for maintenance or cleaning.
d) Install inlet and outlet isolating valves and a Manual Bypass Valve (if
desired).
e)
Install optional water meter if required.
f)
Connecting pipe work and valves MUST be supported to prevent loading on
the valve and pipe work. Before connecting pipe work, flush all lines, close
inlet, outlet and bypass valve.
