Heat exchanger DCU 2 (on the left)
The PCU heat exchanger has two connectors which are marked with arrows as gas inlet
and gas outlet. The connectors of the DCU heat exchangers are also marked with arrows.
Connect the gas inlet connectors of the DCU heat exchangers with a tee connector to the
outlet of the pre-cooling heat exchanger.
Route the gas outlets of the DCU heat exchangers through the top panel of the EC-30C to
the inside of the housing. Inside of the device connect the gas outlets of the DCU to the
inlet connectors of the solenoid valve 1. Connect DCU 1OUT to the front and DCU 2OUT
to the back connector of solenoid valve 1.
If you are using an internal flow alarm sensor FA: Connect the outlet of the solenoid valve
1 on the right hand-side to the gas inlet of the flow meter FM 40. Connect the outlet of the
flow meter FM 40 to the gas outlet which protrudes through the bottom plate of the cool-
er close to the front panel on the left-hand side.
If you are using three optional peristaltic pumps: Connect the heat exchanger outlets to
the peristaltic pumps. Each heat exchanger outlet will be connected to one peristaltic
pump at the front panel of the cooler.
Keep the tubing of the heat exchanger condensate outlets as short and structured as
possible. The tubing does not need to be connected in order.
