Place a container under the strainer to collect any water that spills out of the
basket when it is removed.
Unscrew the clear plastic basket. Remove the screen and rinse it with water.
Replace the screen and the basket.
Algae
To restrict the growth of algae in the reservoir, it is recommended that the res-
ervoir cover be kept in place and that all circulation lines be opaque. This will
eliminate the entrance of light which is required for the growth of most
com-
mon algae.
We recommend the use of Chloramine-T, 1 gram per 3.7 liters.
Configuration
The unit top is secured to the cabinet by four ball stud retainers; one at each
corner. Remove cabinet top by prying upward gently (cover pops off) in
order to perform the following adjustments.
In some cases, the side access panels may need to be removed. The
access panels are secured using screws installed through the bottom of the
cabinet.
NOTE
: Some models have a one piece cover rather than separate top
and side panels. This type of cover is secured by five screws on each side of
the case.
Voltage Selection
Remove the top cover from the cabinet.
The VOLTAGE SELECT toggle switch is located on the right side of the
control box. Two ranges are available: 200-208V and 220-240V. Set the
switch for the appropriate range.
Replace the top cover.
Pressure Relief
Valve
Units with TU pumps have a pressure relief valve is located on the pump
discharge line. The relief valve establishes the maximum operating pressure of
the unit. If the pressure of the fluid leaving the pump exceeds the valve setting,
the relief valve will bypass the fluid within the unit to relieve to the pressure. The
relief valve does not determine the actual operating pressure; the actual
operating pressure is determined by the flow control valve setting and pressure
drop through the instrument being cooled.
If adjustment is necessary, consult our Service Department for assistance
(see Preface, After-sale Support).
