Securely attach all tubing to prevent slipping.
Observe the laws and regulations of the water distribution company valid in the
location where the unit is operated.
For applications near the ambient temperature, the cooling coil
must be connected to the water mains.
Using tubing, connect the cooling coil (25a) to the tap water
supply, and lead the tap water in a sink through the return
connector (25b).

A specific water flow rate of 45 ml/minute 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.
