PPR pipe with nominal out diameter of dn25 and S2.5 series (wall thickness of 4.2mm)
being recommended. Cooling water inlet pipe and hot water outlet pipe of water tank
should also be hot water pipe, PPR pipe with nominal out diameter of dn20 and S2.5
series (wall thickness of 3.4mm) being recommended. If other insulated pipes are
adopted, refer to the above dimensions for out diameter and wall thickness.
Installation of circulating water inlet/outlet pipes: Connect the water inlet of unit
with circulating outlet of water tank and water outlet of unit with circulating inlet of
water tank.
Installation of water inlet/outlet pipes of water tank: Safety check valve (→ on the
valve body points at water tank), filter and cut-off valve must be installed for water
inlet pipe according to the installation sketch of unit. At least a cut-off valve is needed
for the water outlet pipe.
