Installation technical notes
•
The connection pipes must be suitably supported so that they do not weigh down on the machine.
•
Avoid rigid connections between the machine and the pipes, and install vibration dampers.
•
For temperatures values, minimum and maximum water flow rates and the volumes of water in the heat exchanger
water circuit, refer to the Data Book.
•
Any heating elements installed to prevent the pipes from freezing must be kept away from devices, sensors and
materials that the heating elements could damage or cause to malfunction (for example, temperature sensors, plastic
components and power cables).
•
The carrier fluid in the water circuits must be prevented from flowing in the reverse direction as this can damage the
pumps or cause by-passes, affecting the flow and temperature of the system.
•
Install suitable devices to ensure the correct fluid flow rate even with one or more machines switched off, so as to avoid
exceeding the flow rate limits indicated in the tables available in the machine Data Book.
