PRE-OPERATION PROCEDURES
Installation
15. Calibrate pressure for reverse osmosis membrane.
●
Calibrate pressure for the RO membrane ONLY while taking a water sample.
●
This process must be conducted when WE200 is first installed and each time RO
membrane is replaced.
●
Pressure calibration procedure:
(1) Remove the right cover of main unit and
confirm the location of pressure
calibration valve and pressure gauge.
(See Figure 10.)
(2) Turn ELB
“ON”(
｜
) and begin water
sampling process. (See P.25)
(3) Press and hold UNIT while drawing
water sample to display the current
water temperature. (See Figure 11.)
(4) Using the temperature shown in the
information display, refer to Table 1 for a
corresponding pressure. Calibrate to the
appropriate pressure by turning the
pressure adjustment valve.
Example:
If information display shows
“20” (20°C),
corresponding pressure is 0.60MPa.
(5) When calibration is completed, close
the right cover on main unit.

※
If pressure is not calibrated according to the procedure above, specified sample size cannot be
dispensed. If incorrect sample size is suspected after calibrating pressure, call for service.
※
Replacing the reverse osmosis membrane, hosepipes and the pressurization pump at the
same time, every two years, is recommended. Contact nearest sales office or dealer for
assistance.
