circulating water pipe. It is unnecessary if the hole is not needed.
(2) Preparation of pipelines: Circulating water outlet/inlet pipe must be hot water pipe, 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.
(3) Installation of circulating water inlet/outlet pipes: connect the water inlet of the unit with circulating outlet of
water tank and water outlet of unit with circulating inlet of water tank.
