Safety Information

Follow all safety codes. Wear safety glasses and

alert to the potential for personal injury. Understand 

the meanings of the words DANGER, WARNING, 

and CAUTION. DANGER identifies the most serious 

hazards that will result in death or severe personal 

injury; WARNING means the hazards can result in

IMPORTANT

This product was carefully packed and thoroughly 
inspected before leaving the factory. Responsibility 
for its safe delivery was assumed by the carrier upon 
acceptance of the shipment. Claims for loss or damage 
sustained in transit must therefore be made upon the 
carrier as follows:

VISIBLE LOSS OR DAMAGE

Any external evidence of loss or damage must be noted 
on the freight bill or carrier’s receipt, and signed by the 
carrier’s agent. Failure to adequately describe such 
external evidence of loss or damage may result in the 
carrier’s refusal to honor a damage claim. The form 

required to file such a claim will be supplied by the carrier.

CONCEALED LOSS OR DAMAGE

Concealed loss or damage means loss or damage which 
does not become apparent until the product has been 
unpacked. The contents may be damaged in transit due 
to rough handling even though the carton may not show 
external damages. When the damage is discovered upon 
unpacking, make a written request for inspection by the 

carrier’s agent within fifteen (15) days of the delivery 

date. File a claim with the carrier since such damage is 
the carrier’s responsibility.

CAUTION

Use copper conductors only. Unit terminals are not 
designed to accept other types of conductors.  
Failure to do so can damage equipment.

DANGER

Hazardous Voltage!
Disconnect all electric power including remote 
disconnects before servicing. Failure to 
disconnect power before servicing can cause 
severe personal injury or death.

Inspection

When the equipment is received all items should 

be carefully checked against the bill of lading to be 

sure all crates and cartons have been received. All 

units should be carefully inspected for damage when 

received. If any damage is noticed, the carrier should 

make the proper notation on the delivery receipt 

acknowledging the damage. The carrier should also 

fill out a carrier Inspection Report. The McQuay Inc.

Traffic Department should then be contacted. The unit 

nameplate should be checked to make sure the voltage 

agrees with the power supply available.
