Circulator Installation (optional)
In order to successfully install a user-supplied circulator on a Cell Logic Biosafety
Cabinet with Temp-Zone™ package please follow the steps below and refer to Figure 4-
10:
Note: The work surface is heavy and two Easy-Clean™ Prop Rods are provided to
pivot and support the Temp-Zone work area and the work surface.
1. The Temp-Zone work area has supply and return lines for the user-supplied
circulator. Refer to Figure 4-10 and locate the two quick connect elbows on the
left side of the cabinet behind the left side panel.
2. Find a suitable place next to the cabinet or underneath the cabinet to place the
circulator. Accessory shelves for small circulators are available from
labconco.com. Larger circulators should be placed on the floor.
3. Pivot the work surface up and use the Easy-Clean Prop Rods to support the work
surface. Then locate the tubing, insulation, and quick connect fittings shipped
with your Cell Logic. The tubing is 3/8" OD (9.5 mm) and tube inserts must be
placed inside the tubing to properly support the tubing inside the quick connect
fitting. 20 feet (6.1 meters) of tubing length is provided for your convenience.
Note: The tube inserts prevent the tubing from collapsing at connection points and must
be used.
4. Plan, route and cut the tubing from the two elbows on the left side of the cabinet
to the circulator.
5. Locate the quick connect fittings (3/8" tube x 1/8 NPT, 3/8" tube x 1/4 NPT, and
3/8" tube x 3/8 NPT) and install the appropriate fittings to the user-supplied
circulator with appropriate pipe sealant or PTFE tape.
6. Place tube inserts in all ends of the cut-to-size tubing.
7. Cut and install the insulation around the cut tubing lengths.
8. Insert cut tubing lengths into the elbows on the cabinet and then install both
tubing lengths into the circulator to complete the water circulator loop.
9. Read and follow the circulator instructions before operating. The circulator should
have a minimum flow rate of 0.5 GPM (1.9 LPM). In all cases, the temperature of
the circulator will not equal the temperature of samples on the Temp-Zone.
Factors such as the sample vessels, sample sizes, aluminum tube racks, and
length of tubing connecting the circulator to the Temp-Zone can influence the
sample temperature. Circulator settings to hold heated incubator sample
temperatures may require 0.3-2.0°C higher temperatures than the desired
