WARNING

Live Electrical Components!

During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks.

Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.

8. Turn the main power disconnect switch or circuit protector switch, to the unit, “On”.

WARNING

Rotating Components!

Verifying proper components rotation exposes you to rotating components. Have a qualified or licensed service individual who has been properly trained in handling exposed rotating components, perform this task. Failure to follow all safety precautions when exposed to rotating components could result in death or serious injury.

9.Turn the 115-volt control circuit switch 1S2 to the “On” position.

a.Once each compressor or compressor pair has started, verify that the rotation is correct. If a scroll compressor is rotating backwards, it will not pump and a loud rattling sound can be observed.

b.Check the condenser fans for proper rotation. The direction of rotation is clockwise when viewed from the top of the unit.

All Motors are Rotating Backwards;

i.Turn the field supplied disconnect switch or circuit protector switch that provides power to the condensing unit to the “Off” position. Lock the disconnect switch in the open position while working at the unit.

ii.Interchange any two of the field connected main power wires at the unit terminal block 1TB1 or the optional factory mounted non-fused disconnect switch (1S1) in the unit control panel.

Note: Interchanging “Load” side power wires at the contactors will only affect the individual fan rotation. Ensure that the voltage phase sequence at the main terminal block 1TB1 is ABC as outlined in the “Electrical Phasing” section.

Some Motors are Rotating Backwards;

iii.Turn the field supplied disconnect switch or circuit protector switch that provides power to the condensing unit to the “Off” position. Lock the disconnect switch in the open position while working at the unit.

iv.If the electrical phasing is correct, interchange any two of the motor leads at the contactor for each motor that is rotating backwards. Before condemning a compressor, interchange any two leads (at the compressor Terminal block) to check the internal phasing. Refer to the illustration in Figure 46 for the compressor terminal/phase identification. If the compressor runs backward for an extended period (15 to 30 minutes), the motor winding can overheat and cause the motor winding thermostat to open.

10.With the compressors operating, slowly open the “Low Side” valve on the manifold gauge set. The remainder of the refrigerant will be drawn into the system.

NOTICE

To prevent compressor damage due to no refrigerant flow, do not utilize the compressors to pump the system down below 7 PSIG under any circumstances.
