GENERAL SAFETY GUIDELINES 

This guideline is intended for users to ensure safe installation, 
operation, and maintenance of 

Daikin’s unit cooler

. This 

guideline is not intended to replace the system expertise 
available from the system manufacturers. 

This equipment when connected to the outdoor unit is a 
relatively complicated apparatus. During installation, 
operation, maintenance or service, individuals may be 
exposed to certain components or conditions including, but not 
limited to 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 respon-
sibility of 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 
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 this document 
and any referenced materials. This individual shall also be 
familiar with and comply with all applicable governmental 
standards and regulations pertaining to the task in question.
