Heat Exchanger
The heat exchanger does not require any mainte-
nance other than to maintain the level and
quality of the liquid coolant. If the level drops
too low, or the coolant becomes contaminated,
this could result in problems with your instru-
ment.
Do not put any liquid other than distilled
water in the heat exchanger reservoir.
Maintaining Heat
Exchanger Coolant
You should check the level and condition of the
heat exchanger coolant periodically. We recom-
mend routine checks every three to six months,
depending on use of the instrument.
Add distilled water to the reservoir, if necessary,
to keep the reservoir at least 2/3 full. If algae
growth is visible, drain the reservoir bottle, refill
it with distilled water, and add TA Instruments
TGA Conditioner, as described in the next
section.
Draining and Refilling
the Water Reservoir
Drain and refill the heat exchanger water
reservoir as follows:
1. Turn off the POWER switch and disconnect
the heat exchanger cable and water lines
from the instrument cabinet (see Chapter 2
for instructions).
