SAFETY CONSIDERATIONS 

General

 

Improper installation, adjustment, alteration, service, maintenance or use can cause explosion, fire, electrical 

shock or other conditions which may cause personal injury or property damage. Consult a qualified installer; 

service agency must use factory-authorized kits or accessories when modifying this product. Refer to the individual 

instructions packaged with the kits or accessories when installing. 

 

Follow all the safety codes. Wear safety glasses and work gloves. Use quenching cloths for brazing operations and 

have a fire extinguisher available. Read these instructions thoroughly and follow all warnings or cautions attached 

to the unit. Consult local building codes for special requirements. In absence of local codes, it is recommended 

that the USA standard ANSI/NFPA 70, National Electrical Code (NEC), be followed.  

It is important to recognize safety information. This is the safety-alert symbol

.  When you see this symbol on 

the unit and in instructions or manuals, be alert to the potential for personal injury. 

 

Understand the signal words DANGER, WARNING, CAUTION

and NOTE

.

 These words are used with the safety-

alert symbol. DANGER

 

identifies the most serious hazards which 

will 

result in severe personal injury of death. 

WARNING

 

signifies hazards which 

could 

result in personal injury or death. CAUTION is used to identify unsafe 

practices, which 

may 

result in minor personal injury or product and property damage. NOTE is used to highlight 

suggestions which 

will 

result in enhanced installation, reliability, or operation.  

Installation Safety Considerations

 

After the unit has been received and when it is ready to be installed or reinstalled, it must be inspected for 

damage. If damage is detected upon receipt, immediately file a claim with the shipping company or repair. 

This machine must be installed in a location that is not accessible to the public and protected against access by 

non-authorized people. This machine must not be installed in an explosive atmosphere.  

Do not remove the skid or the packaging until the unit is in its final position. The units can also be lifted with slings, 

using only the designated lifting points marked on the unit (labels on the chassis and a label with all unit handling 

instructions are attached to the unit). Use slings with the correct capacity, and always follow the lifting instructions 

on the certified drawings supplied for the unit.  

Safety is only guaranteed, if these instructions are carefully followed. If this is not the case, there is a risk of 

material deterioration and injuries to personnel. These units are not designed to be lifted from above. 

Warranty 

Warranty is based on the general terms and conditions of the manufacturer. Any modifications to the design and/or 

installation made without discussion with Carrier and without advance written agreement will result in the loss of 

the right to any warranty claims and any claim for injury to personnel as a result of these modifications.
