this level, as needed. If the condenser block is overfilled, simply use
the syringe to draw some water out of the fill/drain tube.
•
Fill the syringe with air after filling the condenser block with water, and
syringe the air into the fill tube to remove any water which may adhere
to the side of the tube. This adhesion can cause a false water level
reading in the fill tube if it is not purged. Check the water level reading
in the fill/drain tube, and repeat, if necessary.
•
After filling to the proper level, replace the threaded capnut.
It is recommended that the distilled water in the condenser block
assembly be changed every 2 days with continuous use.
The water level in the condenser should be monitored closely, particularly
if the temperature and water vapor content of the input air stream is
significantly different than the LI-610 set dew point. In this case, water
vapor will either condense out of the input air stream, thereby raising the
water level in the condenser, or evaporate out of the condenser into the
output air stream, lowering the condenser water level.
☞
The condenser water may need to be changed more frequently if the
input air stream contains CO
2
at levels higher than 500 ppm. LI-COR
has found that high CO
2
levels cause the formation of precipitates within
the condenser block, which can cause the water to foam, leading to
unstable flow rates. If the rotameter gauge(s) fluctuates erratically, it
may be an indication that the condenser water needs to be changed.
Power On
1.
The 6200B Rechargeable Battery and the 610-01 AC Module both fit
into the compartment on the back of the LI-610. Loosen the two
thumbnuts, and lift the right side of the retaining strap to access the
compartment. Place the 6200B in the compartment, and replace the
retaining strap. See Table 2-1 for the approximate battery life of the
6000B and 6200B batteries when used with the LI-610.
2.
If you are installing the 610-01, remove the retaining strap. Install
the AC Module and replace the retaining strap. Tighten the thumb-
