General safety guidelines

This equipment is a relatively complicated apparatus. During rigging, installation, operation,

maintenance, or service, individuals may be exposed to certain components or conditions including,

but not limited to: heavy objects, refrigerants, materials under pressure, rotating components, and

both high and low voltage. Each of these items has the potential, if misused or handled improperly,

to cause bodily injury or death. It is the obligation and responsibility of rigging, installation, and

operating/service personnel to identify and recognize these inherent hazards, protect themselves,

and proceed safely in completing their tasks. Failure to comply with any of these requirements could

result in serious damage to the equipment and the property in which it is situated, as well as severe

personal injury or death to themselves and people at the site.
This document is intended for use by owner-authorized rigging, installation, and operating/service

personnel. It is expected that these individuals possess independent training that will enable them

to perform their assigned tasks properly and safely. It is essential that, prior to performing any

task on this equipment, this individual shall have read and understood the on-product labels, this

document and any referenced materials. This individual shall also be familiar with and comply

with all applicable industry and governmental standards and regulations pertaining to the task in

question.

Safety symbols

The following symbols are used in this document to alert the reader to specific situations:

 DANGER

Indicates a possible hazardous situation which will result in death or serious injury if proper care is not

taken.

 WARNING

Indicates a potentially hazardous situation which will result in possible injuries or damage to equipment

if proper care is not taken.

 CAUTION

Identifies a hazard which could lead to damage to the machine, damage to other equipment and/or

environmental pollution if proper care is not taken or instructions and are not followed.

Note: 

Highlights additional information useful to the technician in completing the work being

performed properly.
