Installation Location; Mounting Parts; Pressure Safety Controls; High-Pressure Control - Emerson Copeland Stream 4MF-13X Application Manuallines

In order to avoid refrigerant leaks or other damage the compressors should not be lifted by the
service valves or other accessories.

3.1.4 Installation location

Ensure the compressors are installed on a solid level base.

3.1.5 Mounting parts

To minimize vibration and start/stop impulses flexible mounting should be used. For this purpose
one set of spring mounting parts for each of the Stream models is delivered with each 4M* and
6M* compressor.
Due to differences in weight (cylinder / motor side) different springs have to be used on both
sides. Springs have different colours for easier identification: violet on motor side and orange on
cylinder side.
Operational position
Figure 6: Position of vibration dampers during transport and operation
When Stream compressors are mounted in racks rubber mounting parts should be used.
A compressor may be rigidly mounted, ie, without springs. In this case more shock and vibration
loading will be transmitted to the frame.
Unevenness in the mounting surface will have to be compensated by the rack and/or the
compressor bottom plate/feet. Excessive unevenness can result in too high mechanical stress to
the system and could damage the compressor or rack. Therefore, the flatness of the mounting
location is essential. In addition, both vibration/shock and mechanical stress to compressor can
be avoided by using rubber mounting parts.
If the installation requires a very high level of vibration absorption, additional vibration absorbers
– available on the market – can be fitted between the rails and the foundation.

Pressure safety controls

3.2.1 High-pressure control

A high-pressure control with a maximum cut-out setting of 28.8 bar(g) is required.
The high-pressure cut-out should have a manual reset feature for the highest level of system
protection.

3.2.2 Low-pressure control

The normal minimum cut-out setting is 0.1 bar(g) for R404A.
The low-pressure cut-out should have a manual reset feature for the highest level of system
protection.

3.2.3 Maximum allowable pressures

The maximum allowable pressures according to EN 12693 shown on the compressor nameplate
are obligatory and must not be exceeded.
