Filling the Water Bath
Step 1. Raise the drive unit to its home position and slide it back to allow full
access to the vessels.
Step 2. If applicable, remove one of the vessels and set it aside. Fill the water
bath with ultrapure water by pouring the water through the hole in the
vessel plate. Fill to the level indicated by the operating water level tag
located on the right side of the water bath.
Step 3. Turn on the heater / circulator.
Step 4. Check all connections for leaks. You may notice bubbles from the water
bath inlet as the air in the system is purged. After a few minutes flow into
the bath should be smooth and steady.
Note
If possible, preheat the water to speed achievement of the
desired bath temperature. Use purified water whenever possible
to minimize scale and mineral buildup. Algaecides may be used
to inhibit algae and bacteria growth. Check the label to ensure
the formulation is compatible with the plastic materials used in
the bath construction. See “Water Bath / Acrylic Care” on
page 101.
Note
Though the heater / circulator is designed to be self-priming, it
might be necessary to help the priming process in a dry unit.
With the unit below the level of the water bath, lift one end and
then the other for a minute or two to help air clear from the unit.
