.Installation steps of the damper
Step
Make sure that the flatness of the concrete foundation is within ± 3mm, and then place the unit on the
1
cushion block.
Raise the unit to the height suitable for installation of the damping device. Remove the clamp nuts of the
2
damper.
Place the unit on the damper, and align the fixing bolt holes of the damper with the fixing holes on the unit
3
base.
4 Return the clamp nuts of the damper to the fixing holes on the unit base, and tighten them into the damper.
Adjust the operational height of the damper base, and screw down the leveling bolts. Tighten the bolts by
5
one circle to ensure equal height adjustment variance of the damper.
6 The lock bolts can be tightened after the correct operational height is reached.

2. Water system installation

Notice:
● After the unit is in place, chilled water pipes can be laid.
● The relevant installation regulations should be abided with when conducting connection of water pipes.
● The pipelines should be free of any impurity, and all chilled water pipes must conform to local rules and
regulations of pipeline engineering.

2.1 Basic requirements of connection of chilled water pipes

No.
All chilled water pipelines should be thoroughly flushed, to be free of any impurity, before the unit is operated.
1
Any impurity should not be flushed to or into the heat exchanger.
2 Water must enter the heat exchanger through the inlet; otherwise the performance of the unit will decline.
The inlet pipe of the evaporator must be provided with a water flow switch, to realize flow-break protection for
the unit. Both ends of the water flow switch must be supplied with horizontal straight pipe sections whose
diameter is 5 times that of the inlet pipe. The water flow switch must be installed in strict accordance with
"Installation & Regulation Guide for Water flow switch". The wires of the water flow switch should be led to the
3
electric cabinet through shielded cable. The working pressure of the water flow switch is 1.0MPa, and its
interface is 1 inch in diameter. After the pipelines are installed, the water flow switch will be set properly
according to the rated water flow of the unit.
