4 Magnitude™ Frictionless Centrifugal Chillers – Model WMC IM 1029-2

Installation

Receiving and Handling

The unit should be inspected immediately after receipt for possible damage.

All Daikin centrifugal water chillers are shipped FOB factory and all claims for handling and shipping

damage are the responsibility of the consignee.

On units with factory-installed insulation, the insulation is removed from the vessel lifting hole (also used for

transportation tie-downs) locations and are shipped loose. They should be secured in place after the unit is

finally placed. Neoprene vibration pads are also shipped loose in a control panel.

If so equipped, leave the shipping skid in place until the unit is in its final position. This will aid in handling

the equipment.

Extreme care must be used when rigging the unit to prevent damage to the control panels and refrigerant

piping. See the certified dimension drawings included in the job submittal for the center of gravity of the unit.

If the drawings are not available, consult the local Daikin sales office for assistance.

he unit can be lifted by fastening the rigging hooks to the four corners of the unit where the rigging eyes are

located (see Figure 1). A spreader bar must be used between the rigging lines to prevent damage to the

control panels, piping and electrical panels. The spreader-bar length should be equal to, or no more then 1-

foot shorter than the distance between the lifting holes located at opposite ends of the chiller. The unit will

require a single spreader-bar of this length capable of supporting 1.5 times the shipping weight of the unit.

Separately, all cables and hooks by themselves must also be capable of supporting 1.5 times the shipping

weight of the unit.
