The following guidelines should be used to select a suitable location for the unit lifting:
1. Determine the approximate center of gravity for lifting safety before lifting the unit.
2. Always test-lift the unit to determine the exact unit balance and stability before hoisting
it to the installation location.
3. Ensure that all rigging and lifting equipment is operated by qualified personnel.
4. Ensure the rigging equipment and material have the required capacity for the job and
that all items are in good condition.
5. Ensure the lifting straps, cables, or chains used, clear the sides and corner edges of the
unit. If not damage to the unit may occur.
4.0 ACCOUSTICAL CONSIDERATION
With any mechanical system, a certain amount of vibration and noise is generated. To ensure a successful
installation of these units, factory has provided the internal vibration isolators for compressors.
If additional vibration isolation is desired, neoprene is recommended under 4 corners of unit.
Care must be exercised to isolate the unit and piping from walls and ceiling.
Besides vibration, which is transmitted by conduction, radiated noise and fan noise must also be addressed.
Compressors, and etc., all generate noise and can be radiated to the occupied space.
The most common approach to reducing this possibility is to locate the units in least sensitive areas. This could be
near stairs, elevators or lavatories.
Good acoustical practices should be employed when designing the wall between the machine room and the occupied
space. All openings around doors should be sealed. The return air opening must be acoustically treated.
Noise will also be carried through the fan and supply ductwork to the occupied space. When the sound attenuation
package is required, you should consider installing sound attenuation in the supply ductwork.
