Step 4 - Calculate Ion-exchange Cartridge Life
1. Calculate the maximum ion-exchange cartridge
pack life. Under emergency by-pass processing
and with your mains water conditions, to maintain
a supply purity of 1 M
.cm to the analyzer.
Time between
pack changes
=
55,000
(Conductivity of
mains water)
x (Water consumption of
analyzer l/hr)
Example
Mains water conductivity
= 605µS/cm
Water consumption of analyzer = 20 l/hr
Time between
pack changes
=
55,000
605 x 20
Time between
pack changes
=
4.5 hrs
In the absence of information on mains water conductivity assume a
pack life of 2 hrs if the analyzer consumes 20 l/hr.
If flow starts to decline this may be solved by changing the 0.2µm filter.
Step 5 - Return to Normal Operation
1. ONCE the unit has been repaired the unit must
be returned to normal operation.
2. RE-CONNECT the mains supply to the inlet of
the
MEDICA
and re-adjust supply pressure.
3. ENSURE the emergency by-pass valve is closed
inside the
MEDICA
.
4. CHANGE Ion-exchange cartridge pack and
0.2µm filter.
(See Section 7.2 and Section 7.4).
5. PERFORM 'Initial Start up' routine.
(See Section
5.6).
