Connecting an external vessel
Danger from unsealed pump connections.
Secure tubing connections against slipping.
This temperature control system is designed to control the temperature of
an external, closed-loop vessel (temperature loop).
The tubing connections between the temperature control system and the
attached external vessel should be as short as possible. This is the only
way to fully utilize one of the main advantages of this system (its speed!).
•
Remove the screw
caps from the pump
connections (4, 5)
and use appropriate
tubing to connect the
unit to the external
system (M24x1.5 /
27mm wrench).
The pressure line (4,
OUT) must be
attached to the
lowest fluid
connection point of
the external vessel to
prevent air from
becoming trapped.
•
Connect one end of
an appropriate tube
to the overflow (3)
adapter and place
the other end into a
suitable container.
The container must
always be lower than
the "overflow" outlet
(M16x1 / 19mm
wrench).
The below picture shows the W80, but the A80 connects to the
external vessel in the same way.
If bath fluid drains out through the overflow (3) at your highest working
temperature, direct the liquid into a suitable container. If the unit also
triggers a low fluid-level alarm at the lowest working temperature, then
you should use an external expansion vessel to avoid this problem.
