5 Installation of Unit
5.1 Installation of Product
5.1.1 Pipeline Connection for Hot Water System
Preparation of pipeline: cooling water inlet tube and hot water outlet tube for water tank must
adopt hot water tube. It is recommended to use the PPR tube with nominal external diameter of
G1/2, and should adopt S2.5 (3.4mm wall thickness) series.
Installation for inlet and outlet tube of water tank: inlet water tube must be installed with check
valve (note the installing direction of check valve, the "→" arrow directs to the heat insulating water
tank), filter, cut-off valve, and the installing order must be the same as the installing sketch map of
unit. At least one check valve should be installed in the water outlet tube.
Installation for blow-off pipe in bottom of water tank: lead the drain outlet with PPR tube to the
floor drain, one check valve must be installed in the blow-off pipe and it should be installed in the
position that is convenience for operation.
After all the pipelines are well connected, conduct leak detection first (for specific leak
detection operation, please refer to debugging part of the unit). After confirming there is no
leakage, conduct thermal insulation for all the water pipeline system, especially for the joints such
as valves and pipe joints. It is recommended to use the thermal insulating cotton with thickness not
less than 15mm. After covering the cotton, use the tieline to truss the water pipe, water
temperature sensor, and electric wire.
5.1.2 Pipeline Connection for Refrigerant System
The pipeline for hot water converter to connect to indoor unit has been sealed by welding
before leaving the factory. The copper tube for refrigerant of indoor unit is led out from hot water
converter; the sealed tube of indoor unit should be unsoldered. Sketch map for installation is as
below. Conduct thermal insulation for the refrigerant copper tube, and thickness of thermal
insulating material should not be less than 8mm. Make sure that the refrigerant copper tube is
firmly sealed and connected without leakage.
