Water Piping 
• Install water pipes according to the regulations of respective countries. 
• Install water pipes in a freeze-free place. 
• Make sure that water pipes have sufficient pressure resistance (The setting value of the pressure 
relief valve is 0.3 MPa). 
• Do not use zinc plated water pipes. When steel pipes are used, insulate both ends of the pipes. 
 
Water Connections 
• Install a strainer with 30 to 40 meshes (procure locally) at 
the water inlet of the Hydro Unit. 
•  Install drain cocks (procure locally) for water charge and 
discharge at the lower part of the Hydro Unit. 
 
 
Water Piping Limitations 
Design the water pipe length within the QH 
characteristics of the pump (flow-rate and pump 
head). 
The maximum height difference for the water pipes i
7 metres. 
 
 
 
 
Piping to hot water tank (option
Water supplied to the hot water cylinder is branched by a 
motorized 3-way valve (procured locally). 
Connect the hot water cylinder to port A (open when 
energized) of the valve. 
 
Piping to 2-zone operation (option) 
To perform 2-zone temperature control circulate water using another pump (procured locally) 
through a motorized mixing valve (procured locally) and a buffer tank (procured locally).
