Technical data for the plumbing system:
- Minimum working pressure: 2 bar
- Working pressure: recommended operating field 3 ÷ 4 bar
- Maximum working pressure: 5 bar (Install a pressure reducer for higher hydraulic pressures)
- Maximum working temperature: 65°c
- Floor waste required with capacity ≥ 60 l/min.
- 18,2 kg empty weight of the complete head shower (with water about 20,7 kg)
