temperature is over 178 °C (350 °F), then the casin g
support legs may need to be cooled. Cool water - less
than 32 °C (90 °F) - should be run through the legs at a
flow rate of at least 0.06 l/s (1 gpm) as shown below.

4.6.5.4 Piping connection - Heating/cooling fluid
for jacketed/casing
The piping connections for jacketed casings are shown
below. The flow rate of the cooling water - less than
32 °C (90 °F) - should be at least 0.13 l/s (2 gpm) .

Notes:
1. When circulating steam, use top hole for inlet. Both bottom
holes must be plumbed together for outlet, to ensure draining
both sides of jacket.
2. When circulating liquid use both bottom holes as inlets. Use top
hole as outlet.
