2.0 INSTALLATION
2.5 FOUNDATION
2.5.1 AIR COOLED UNITS
The foundation must be level for proper
operation and functioning of controls and
provision must be made for supporting
the individual load points as shown in
Figure 2.5.1, Roof mounted units must be
supported on adequate steel structures. If
units are located on the ground level, a
concrete plinth is recommended.
2.6 VIBRATION ISOLATION
Under certain critical conditions, it may be
necessary to install vibration isolators under the
base of the Packaged Chiller.
Rubber-in-shear or spring vibration isolators are
offered as optional items. When spring isolators
are used, flexible connectors must be installed in
the water piping system and in the refrigerant
lines of split systems. Kindly note that: These
flexible connectors must be suitable for the fluid
and pressures involved.
When using flexible connectors in refrigerant
piping, they must be mounted in the refrigerant
discharge and liquid lines close to the packaged
chiller, in a horizontal position and parallel to the
compressor crankshaft.
All piping which is external to the packaged chiller
must be supported by spring mounted hangers
and any piping which goes through the wall,
ceiling or floor should be properly pivoted to
prevent transmission of piping vibration to the
structure.
