5.4 Maintenance of water side
After the bottom plate is horizontal, connect the water pipe of SHELL&TUBE heat exchanger. Because the
SHELL&TUBE heat exchanger will be cleaned or changed, the exterior pipe should be disassembled. The
discharging valve should be installed on the higher position to ensure the air can be exhausted completely. The
water relief valve is installed on the lower position to discharge water easily.
On the water circuit, there is the temperature indicator and the pressure indicator. In order to
disconnect the unit and the exterior pipe in maintenance, the stop valve is installed on the water circuit. To
reduce the block in the evaporator, it is important to deal with water before the chilled water enters the
evaporator. After the whole system is full of water, startup the pump to exhaust the air in the system.
Even if the cool load changes, heat pump unit also need to operate under the stable water flow. Generally,
the unit can operate normally under the design water flow with tolerance of plus/minus 10%. The changing water
flow can result in unstable operation control, especially for the control of cool/hot water inlet/outlet temperature.

Note:
1.The above supporting points do not include the weight of water circuit
out of the unit and the exterior power cable bracket
2.The foundation must be plane
3.The installer can adopt the expansion bolt M16 or embedded foundation
bolt, the embedded depth is about 240mm(for reference) and the
extention length is about 50mm(for reference)
4.When used rubber shock absorber, there need not joint among the unit,
the foundation and the rubber shock absorber, only to place the shock
absorber between the unit and the foundation
5.When used spring shock absorber, there is joint between the unit and
the absorber,while we suggest no joint between the absorber and the
foundation. After the absorber is installed, please adjust it until the bottom
plate is horizontal.
