3-1 Uncrating

2 hp to 5 hp models are shipped mounted on a skid, enclosed in a plastic wrapper, and contained in a cardboard box. 7.5 to 40 hp 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.

Note: 2 to 5 hp models: remove the nails holding the box to the skid and lift the box off carefully, avoiding staples in the 1’ x 4’ wood supports. Cut the steel banding.

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. (20 hp to 40 hp units feature special lifting openings.) 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.Temporary hardware has been installed to prevent side panels from shifting in transit. Remove hardware.

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

Caution! Never remove the unit from the front (electrical control end) or the rear (pipe connection end). Damage may result.

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 45-57 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. Note the outline drawings for egress into the cabinet. Make sure all electrical connections are tight.

Typical wiring schematics are located on pages 70-78 in the Appendix.

Warning! Make sure that electrical connections comply with all applicable electrical codes. Ground the chiller in accordance with NEC Article 250.

Operation voltage must be within plus or minus 10% of the nameplate rating. Phase imbalance must be below 10%
