6.3 Indoor unit suspension
◇Select the suspension foundation
◇The suspension foundation is a structure of either wooden frame or
reinforced concrete. It must be firm and reliable to bear at least 4 times
weight of itself and capable of bearing vibration for long periods;
Fixing of suspension foundation
◇Fix the suspension bolts either as shown in the picture or by a steel or
wooden bracket;
◇Adjust the relative positions of the suspension hooks to ensure the indoor
unit is level in all directions. Use a spirit level to ensure this, otherwise
water leakage, air leakage etc. will be resulted;
◇Tighten the nuts and ensure that the hooks are tightly connected to the nuts and sMDms, and there is no
phenomenon of virtual hanging;
◇After the unit is installed ensure it is secure and does not shake or sway.
6.4 Drainage pipe installation
◇The drain pipe should be properly insulated to prevent the generation of condensation, see picture as
follows:
Heat insulation material: rubber insulation pipe with the thickness of more than 8mm
◇Drainage pipe must have a downward gradient (1 / 50 1 / 100).If the drain pipe is installed ups and
downs, it will cause water backflow or leakage etc.
The pipe should not rise at any point.
◇When finish installation,please carry out the drainage test to ensure that the water flow through the
pipeline fluently, and carefully observe the junction to ensure that there is no water leakage at the
junction. If the unit is installed in the newly built house, strongly recommend that this test taken before
the ceiling installation. Even it is the heating only unit, this test is unavoidable.
