Optional cooling

Circulating pressure must not exceed 0.8 bar (12 psi) above ambient pressure. Do not
connect the cooling core to an unregulated coolant source such as a water tap.

To connect the cooling core to a circulator bath, follow these steps:

Action

Step

Slide hose clamps (4 in total) onto each end of two lengths of 8 mm (5/16")
vinyl or silicone tubing.

1

Attach one end of each length of tubing to a cooling core port.

2

Attach the free ends of each length of tubing to the circulator bath ports;
one to the inlet and the other to the outlet.

3

Secure the connections with the hose clamps.

4

Install the upper buffer chamber
core

CAUTION

Circulate only water or 50/50 water/ethylene glycol through the
heat exchanger. Never use anti-freeze or any organic solvent in
the heat exchanger.

Action

Step

Steady the lower chamber with one hand and then hold the core with the
other hand.

1

Position the lower chamber on the positioning tabs.

2

Press down, listening for the core to snap into place. (Alternatively, depress
both release tabs at either side, position the core on the positioning tabs,
press into place, and release the tabs. Check that the core is secure.)
