Section 1. Safety Information

WARNING

!

SAFETY HAZARD! 

This information is intended for use 

by individuals possessing adequate backgrounds of electrical and 
mechanical experience. Any attempt to repair a central air condition-
ing product may result in personal injury and/or property damage. 
The manufacturer or seller cannot be responsible for the interpreta-
tion of this information, nor can it assume any liability in connection 
with its use.

LIVE ELECTRICAL COMPONENTS! 

During instal-

lation, testing, servicing, and troubleshooting of this product, it may 
be necessary to work with live electrical components. Failure to fol-
low all electrical safety precautions when exposed to live electrical 
components could result in death or serious injury.

CAUTION

!

WARNING

!

CORROSION HAZARD! 

To prevent shortening its service 

life, the air handler should not be used during the finishing phases 
of construction. The low return air temperatures can lead to the 
formation of condensate. Condensate in the presence of chlorides 
and fluorides from paint, varnish, stains, adhesives, cleaning com-
pounds, and cement creates a corrosive condition which may cause 
rapid deterioration of the cabinet and internal components.

CAUTION

!

CAUTION

!

HAZARDOUS VAPORS! 

Do not install an air handler 

with a non-ducted return in the same closet, alcove, or utility 
room as a fossil fuel device. Hazardous vapors can be distributed 
throughout the conditioned space and equipment damage can 
result.

Important: 

Panel damage can occur with prolonged 

exposure to POE lubricants.  Air handler front panels 
that come in contact with POE oil must be washed 
immediately with soapy water.

WARNING

!

This product can expose you to chemicals including lead, which 
are known to the State of California to case cancer and birth defects 
or other reproductive harm. For more information go to www.
