Handling

While this unit was constructed with quality and dependability in mind, damage still may occur during handling of the unit for installation. Exercise extreme caution to prevent any damage from occurring to the refrigerant system. This unit contains a system pressurized with refrigerant that, if damaged, could leak into the atmosphere or cause bodily harm due to the extreme cold nature of expanding refrigerant. Use protective equipment such as gloves and safety glasses to minimize or prevent injury in case of a system leak during installation.

The system design and installation should follow accepted industry practice, such as described in the ASHRAE Handbook. Adequate space should be left around the unit for piping coils and drains, filter replacement, and maintenance. Sufficient space should be provided on the side of the unit for routine service and component removal should that become necessary.

Lifting

1.Before lifting, be sure that all shipping material has been removed from unit.

2.To assist in determining rigging requirements, weights are provided in the Installation, Unit Weights and Recommended Roof Opening section of this manual.

3.Unit must be lifted by all lifting lugs provided on base structure.

4.Rigger to use suitable mating hardware to attach to unit lifting lugs.

5.Spreader bar(s) must span the unit to prevent damage to the cabinet by the lift cables.

6.Always test-lift the unit to check for proper balance and rigging before hoisting to desired location.

7.Never lift units by weatherhoods.

8.Never lift units in windy conditions.

9.Preparation of curb and roof openings should be completed prior to lifting unit to the roof.

10.Check to be sure that gasketing (supplied by others) has been applied to the curb prior to lifting the unit and setting on curb.

11.Do not use fork lifts for handling unit.

Warning

All factory provided lifting lugs must be used when lifting the units. Failure to comply with this safety precaution could result in property damage, serious injury, or death. Unit weights assume rooftop configuration with weatherhoods, filters, outdoor air damper, six row DX coil, integral condensing section and an indirect gas fired furnace.

Lifting Lugs

NOTE

On some models, one lifting lug may be positioned directly in front of the condensate drain connection.

Any lifting lug that is located as shown should be removed in order to permit installation of the P trap drain kit.
