2-7. Safety precautions at the installation on the foundation
Put the chiller on the foundation slowly and gently with careful attention to the foundation bolts positions.
Also pay attention to avoid falling or turnover accident.
3. Requirements for the foundation
Refer to the information on the foundation as shown in the contract specifications.
Set the chiller on the foundation bolt position.
3-1. Foundation work
(1) The concrete foundation should be finished in consideration of the required level for the chiller.
(2) The foundation shall meet the loads bearing requirements and also avoid trouble of a differential
settlement between the main body and the high temp. generator.
(3) Prevention against noise and vibration should be taken into consideration.
3-2. Accuracy of dimensions and levelness of the foundation
Important precaution for the foundation dimensions are flatness of each foundation and levelness error
between two foundations parted in a longitudinal direction of the chiller.
Permissible levelness for the absorption chiller installation
The permissible levelness for the absorption chiller is 2/1000 in both longitudinal and width direction.
For the 6 meter(20 feet)-long absorption chiller the error should be 12mm(half-inch) and under in
longitudinal direction, and for 2 meter(6’9/16”)-wide unit it should be 4mm(5/32 inch) and under in width
direction.
Cement mortar finish is not required for the foundation surface but trowelled finishing of the concrete
should be performed in consideration of the above levelness.
12mm (half-inch)
and under
6 m (20 feet)
4mm (5/32 inch)
and under
2m (6’9/16)
