System Sanitization
Frequency of sanitization will vary, depending on quality of
feedwater and usage. Sanitization is necessary if residual
deposits are evident inside the reservoir, or if a new 0.2
micron final filter clogs rapidly. For sanitization procedure,
see “System Sanitization Procedure” in the “Initial
Operation” section of this manual.
Prefilter Replacement
The prefilter is designed to remove particles from your in-
coming water source. It is impossible to predict expected
life. After 1 year of service or as a pressure drop is detect-
ed by the unit, the display will alert the user to replace pre-
filter. All pressure sensor data can be obtained in the RO
Options screen. The pressure differential represents the dif-
ference between the prefilter inlet pressure and the prefilter
outlet pressure. Before replacing the prefilter, ensure that
all power and water are disconnected from the unit.
1.
Remove the prefilter (see Fig. 21) by first pressing
the upper and lower thumb buttons on the quick
disconnect fittings.
2.
Remove the prefilter by pulling the cartridge
straight out.
3.
Replace the prefilter by following the instructions
located in the “Prefilter Installation” section of this
manual.
4.
Reset the prefilter timer by following the “Timers”
section of this manual.
MPS Replacement
The MPS cartridge incorporated in your DIamond TII is
designed to prevent scale buildup on the membrane(s).
This cartridge must be replaced when the anti-scalant level
is approximately half dissolved. At this point, the quantity
of anti-scalant entering the water is insufficient to effectively
prevent scale accumulation on the membrane(s). Before
replacing the MPS cartridge, ensure that all power and
water are disconnected from the unit.
1.
Remove the MPS cartridge by pressing the upper
and lower thumb buttons on the quick disconnect
fittings.
