General safety guidelines

Important: Read before proceeding.

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.
