4.5 Vibration Reduction
The unit shall be securely attached to the foundation through the mounting hole by following the steps
below.
(1)
Be sure the planeness of the concrete foundation is within ±3mm and the foundation shall be covered
by a rubber pad.
(2)
Lift the unit until to the height where it is available to install the spring shock absorber.
(3)
Remove screws fixing the spring shock absorber.
(4)
Place the unit on the spring shock absorber and align the bolt holes of the spring shock absorber with
the mounting holes on the base of the unit.
(5)
Tighten screws removed in step 2.
(6)
Adjust the height of the spring shock absorber and make sure the deflection is equal all round the
spring shock absorber.
(7)
Tighten the locking screws.
4.6 Water System
Considerations stated below shall be taken carfelly for the water system.
(1)
Each water inlet and outlet should be labeled properly to avoid misconnection.
(2)
A flexible connector should be used at the chilled water outlet to reduce vibration transmission.
(3)
A manometer, a thermometer and a gate valve shall be installed at the chilled water inlet /outlet.
Moreover, a drain valve shall be installed at the outlet and an air release valve shall be installed at
the inlet. At the highest point of the water system, another release valve shall be installed, while at the
lowest point of the water system, another drain valve shall be installed to facilitate drainage.
(4)
The water inlet/outlet pipe should be tightly insulated to reduce heat loss and dewing. When pipes are
exposed under 0
℃
, a electric heater shall be installed.
(5)
There surely be some foreign matters in the water system which would generate scale on the surface
of the heat exchanger, so a filter shall be installed upstream of the water pump.
(6)
The unit shall be bypassed during flushing to prevent drain out from entering the system.
