Step Content
1
Make sure that the flatness of the concrete foundation is within ±3mm, and then place the unit on the
cushion block.
2
Raise the unit to the height suitable for installation of the damping device. Remove the clamp nuts of the
damper.
3
Place the unit on the damper, and align the fixing bolt holes of the damper with the fixing holes on the unit
base.
4 Return the clamp nuts of the damper to the fixing holes on the unit base, and tighten them into the damper.
5
Adjust the operational height of the damper base, and screw down the leveling bolts. Tighten the bolts by
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.
11.2 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.
12.2.1 Connection requirements of chilled water pipes
a. All chilled water pipelines should be thoroughly flushed, to be free of any impurity, before the unit is
operated. Any impurity should not be flushed to or into the heat exchanger.
b. Water must enter the heat exchanger through the inlet; otherwise the performance of the unit will decline.
c. 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 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.
d. The pump installed in the water pipeline system should be equipped with starter. The pump will directly
press water into the heat exchanger of the water system.
e. The pipes and their ports must be independently supported but should not be supported on the unit.
f. The pipes and their ports of the heat exchanger should be easy to disassemble for operation and cleaning,
as well as inspection of port pipes of the evaporator.
g. The evaporator should be provided with a filter with more than 40 meshes per inch at site. The filter
should be installed near to the inlet port as much as possible, and be under heat preservation.
