17.3 Connection of Waterway System
If connection between water tank and indoor unit should be through the wall, drill a
holeφ70 for pass of circulating water pipe. It is unnecessary if the hole is not needed.
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.
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.
Installation of blow-off pipe at the bottom of water tank: Connect a piece of PPR pipe
with drainage outlet to floor drain. A cut-off valve must be installed in the middle of the
drainage pipe and at the place where it is easy to be operated by the users.
After connection of all waterway pipelines, perform leakage test firstly (refer to debugging
of the unit). After that, bind up the water pipes, water temp sensor and wires with
wrapping tapes attached with the unit.
Refer to Installation Sketch of Unit for details.
