Brookfield Bath, Model TC-602 - Manual (Page 5)

1.5 Pump Inlet and Outlet Connections
The pump inlet and outlet ports are female ¼ inch NPT connections that permit use of barbed tubing
adapters or hard plumbing fittings. ½ inch (13mm) ID tubing may also be slid over these connections
and held in place with a hose clamp. If the pump inlet and outlet are not used for external circulation,
they should be connected using the tubing provided with the unit in order to optimize fluid mixing
within the reservoir.
Picture 1: Inlet to Outlet Connection. When bath is not circulating with an external
device, the tubing provided with the unit should be used as shown above.
The nylon barbed tubing adapter fittings supplied with the unit are intended for temperature control from
-40°C to 93°C. For controlling temperature above 93°C, brass, stainless steel, or Teflon
® fittings are
recommended. ¼ inch NPT to M16 stainless steel male adapter fittings are provided with all 50Hz
models.
IT IS THE USER’S RESPONSIBILITY TO ENSURE THAT THE TUBING AND FITTINGS
CONNECTED TO THE CIRCULATOR ARE COMPATIBLE WITH THE BATH FLUID AND
TEMPERATURE RANGE BEING USED.
NOTE: The use of quick-connect fittings will restrict flow rate. Therefore a high or maximum pump
speed should be used.
1.6 Closed Loop Circulation
Connect the pump inlet and outlet to the external apparatus (See Picture 2 below). To maintain
adequate flow, avoid restrictions in the tubing. When connecting the Circulator to more than two
closed loops, the use of a manifold made of "Y" adapters to divide the fluid into multiple banks is
recommended. After setting up multiple closed loops, check for adequate flow at the return manifold
of each loop and check that the bath fluid is at an adequate level. A booster pump may be added to
closed loops without damaging the Circulator’s bath pump.
