Chapter 3: Installation

3-1 Uncrating

All models are shipped mounted on a skid, enclosed in a plastic wrapper, and open-crated on all four sides and top.

1.Pry the crating away from the skid.

2.Use a pry bar to remove the blocks securing the unit to the skid.

3.Lift unit from sides, inserting forklift under the base. The forks must be equidistant from the centerline of the unit and the unit must be balanced on the forks. Lift slowly and only high enough to clear the skid. Use a pry bar if necessary to carefully remove the skid from the unit.

4.Lower slowly. The unit should land on its casters or rails and can then be moved into position.

5.Retain the crating material for reshipping the chiller in case hidden shipping damage is found.

3-2 Electrical Connections

Supply electricity of the voltage, phase, and cycle listed on the serial tag. Total running amps are also found in the specification tables on pages in the Appendix.

Bring properly sized power leads and ground from a fused disconnect (installed by your electrician) to the unit. Use dual-element fuses in the disconnect switch, sized according to the National Electrical Code recommendations. Make sure all electrical connections are tight.

Important!

Refer to your local electrical requirements for proper feeder conductor and supply disconnecting sizing. For instance, in the United States refer to National Electric Code (NEC) Article 430-24 through 430-26, Table 310.15(B)(2)(a)

Note:

For all chillers manufactured with Variable Frequency Drives the

 

voltage may vary up to 10% from the converter nominal voltage.

 

However, the phase-to-phase input voltage imbalance must not

 

exceed 3%. If the input voltage does have an imbalance from phase

 

to phase greater than 3% then a line reactor must be installed to

 

prevent faults within the VFD.

 

For remote condenser units, the maximum recommended motor

 

cable length between the VFD and the motor without output chokes

 

is 30 m (100 ft). With output chokes the motor cable length may be

 

extended to 65 m (195 ft).
