Mechanical Installation
3.5. Removing Transportation Fastener and Vibration Absorber
The fasteners and vibration absorbers are mounted on the equipment to protect partial components from
getting damaged and distorted due to bumping, impact, and resonance. Removal of these fasteners and
absorbers is necessary before installation and commissioning the unit.
• Removing retaining metal plates to x the compressor in transit
Damping rubber pads are installed on the compressor’s feet to buer the compressor vibration in operation
and reduce the vibration noise, but rubber pads cannot appropriately handle the shaking of the compressor
in transit, thus resulting in loosening of related connecting pieces and wear of some parts. To avoid these
possible problems, retaining metal plates are mounted on the three feet (two feet in case of CR025) to x the
compressor before shipment.

1 Retaining Metal Plates
Figure 3-22 Retaining Metal Plates
After installation and before commissioning of the units, remove all the retaining metal plates, and then mount
bolts and gaskets in the reverse order to that of installation.
• Removing pipe fastener
If the copper pipe gets close to the metal plate, it may result in wear and tear of the copper pipe. To prevent this
from occurring, vibration absorbers are tted between them. However, these objects need to be removed and
then the area must be cleaned prior to installing and commissioning.
