5.5. Water connection
For technical specifications on water supply, refer to
section 3.4.
• Before the unit is connected to the water supply
pipe, the supply line should be rinsed thoroughly
in order to remove impurities.
• When installing piping, avoid air traps. Use clamp
connections for all pipe connections to the unit for
easy maintenance and disassembly.
• The connection for water must be made at the
top of the unit. Refer to layout drawing in section
12.2.
• Minimum diameter of the supply pipe must be at
least Ø38 external (Ø35mm internal).
• The unit must be fitted with a closing valve for
water on the inlet (see image 110009521).
• For best performance, install a filter on the inlet to
prevent impurities (refer to image below).
To minimize pressure loss in the supply line:
• Avoid long pipe lines.
• Use low pressure resistance ball valves.
• Avoid fittings with high pressure loss.
