NOTICE !
1
Dimensions and material for the water inlet and outlet shall be in
accordance with the above table. The hot water pipe shall be S2.5 (wall
thickness: 2.7mm) DN15 (outer diameter) PPR pipe. All used PPR pipes
shall comply with GB/T18742. When other similar pipes are taken as
alternatives, refer to the outer diameter and wall thickness stated above.
When the check valve is used outdoor, it should be made of PPR to prevent
from being damaged by frostbite under the low temperature environment.
2
Water pipes are allowed to be routed only after the unit has been installed
properly. Note that do not let dust or other foreign matters enter the pipe
system.
3
When all pipes have been in place, take a leak test and then insulate all
pipes. Special attention shall be drawn to the valves and joints. The
insulation material shall be at least 15mm thick.
