3 Setting Up the 708-DS / 709-DS
Level Instrument - Re-verification
1 With the water bath filled (if applicable), re-verify the instrument
level front to back and right to left using a bubble or digital level.
Heater / Circulator Power-up (708-DS)
1 Turn on the power to the heater / circulator using the switch located
on the unit.
2 Ensure the water flow through the heater / circulator begins. To
release air trapped in the pump or heater cartridge, follow the
priming instructions located on the heater / circulator.
3 Repeat the procedure, if necessary.
4 Ensure no leaks are present at any of the tubing connections.
NOTE
Use ultrapure water when possible to minimize scale and mineral
buildup. Use algaecide to inhibit mold and bacteria and algae growth.
Check the label to ensure the formulation is compatible with the plastic
materials used in the water bath construction. The flow paths of the
heater / circulator are primarily stainless steel and should tolerate most
clear water bath formulations.
