Filling Requirements

Ensure the reservoir drain port is closed and that all plumbing connections are securely plumbed
or capped. Also ensure any residue is thoroughly removed from the reservoir before filling.
To avoid spilling, place your samples/trays into the bath before filling. Also make allowance for
splashing of water from tray oscillation movement.
Slowly fill the reservoir. When adding, point the opening of a container away from yourself.
Fill the reservoir with a minimum of one inch and a maximum level one inch lower than the tank
upper surface.
Note Monitor the fluid level whenever heating the fluid.
To conserve energy, reduce evaporation, and increase temperature control accuracy, use the
supplied gable cover. Do not use aluminum foil as a cover, as it may cause corrosion due to an
electrochemical reaction.

Filling with Thermal Beads

Use the controller to configured the bath before using the thermal bead mode, see Chapter 4
Changing a Setting.
Figure 3-2 – Thermal Beads Reservoir Plug
Before filling the reservoir with beads
ensure the supplied reservoir plug is
securely installed into the drain.
Note For safety considerations,
enabling the mode automatically derates
the bath's heater performance, and
it turns off low fluid protection so the
beads don't trip the alarms.
This mode also derates the bath's
stability and uniformity capability.
