For applications near the ambient temperature, the cooling coil (20)
must be connected to the water mains.
Using tubing, connect the cooling coil to the tap water supply,
and lead the tap water in a sink through the return connector.
A specific water flow rate of 750 ml/minute (15 °C) is sufficient
to compensate for the characteristic temperature.
For applications near ambient temperature (20 °C), the cooling
water temperature should at least be 5 °C below the working
temperature.
