Checking and Refilling the DI Water Reservoir
Water from the DI reservoir can be lost when using the analyzer with the
autosampler or grab sampling. The level of the DI Water reservoir should be
checked periodically and refilled as necessary. To check the level of DI water
in the reservoir:
WARNING
Checking and refilling the DI water reservoir requires access to the inside of the
analyzer. To avoid potentially dangerous shock, disconnect the power cord
before opening the analyzer's top panel.
For this procedure, 10 to 20 mL of deionized water will be needed and the
water bottle from the TOC accessories kit.
CAUTION
The water used to replenish the DI Reservoir must be deionized from a pure
source. This water may not be post-RO water!
1. Turn the power switch off on the left-hand side of the analyzer and
disconnect the power cord.
2. Open the analyzer top panel by pushing back on the two black
latches and lifting the panel upward. The DI reservoir is the black
plastic box with a valve and two fittings attached on top. The valve is
located between the resin bed and the circulating pump at the back,
center of the analyzer (see Figure 8-15).
When the reservoir is completely filled, the plastic box will have a uniform dark
color. If an air bubble is present, the bubble will appear as a lighter colored
(almost white) area in the plastic box. There is no need to refill the reservoir if
the box appears to be a uniform dark color. If an air bubble is present, follow
the steps listed below to add DI water to the reservoir.
