Safety considerations

The installation of Induction 
Units and all associated 
components, parts and 
accessories which make up 
the installation, shall be in 
accordance with the regulations 
of all authorities having 
jurisdiction and must conform to 
all applicable codes. Only trained 
and qualified service personnel 
using good judgment and safe 
practices should install, repair 
and/or service air conditioning 
equipment. 

Untrained personnel can 
perform basic maintenance 
functions such as cleaning coils 
and cleaning or replacing lint 
screens. All other operations 
should be performed by trained 
service personnel. When 
working on air conditioning 
equipment, observe precautions 
in the literature, tags and labels 
attached to the equipment and 
all other safety precautions that 
may apply. 

Improper installation, 
adjustment, alteration, service, 
maintenance, or use can cause 
hazardous conditions which 
may cause serious personal 
injury and/or property damage. 
Consult a qualified installer, 
service agency, or your sales 
representative for information or 
assistance. 

The equipment must always be 
properly supported by rigging and 
lifting equipment. Any temporary 
supports used during installation 
or maintenance must be designed 
to adequately hold the equipment 
in place until equipment is 
permanently fastened and set 
in its final location. All supports 
must meet applicable local codes 

and ordinances.

All fastening devices must be 
designed to mechanically hold the 
assembly in place without the ability 
to loosen or break away due to 
system operation or vibration.

Never use bulky or loose fitting 
clothing when working on any 
mechanical equipment. Gloves 
should always be worn for protection 
against heat, sharp edges and all 
other possible hazards. Safety 
glasses should always be worn, 
especially when drilling, cutting or 
working with chemicals.

Never pressurize equipment beyond 
specified pressures as shown on 
unit rating plate. Always pressure 
test with an inert fluid such as water 
or dry nitrogen to avoid possible 
damage or injury in the event of a 
leak or component failure during 
testing.

Always protect adjacent flammable 
material when welding or soldering. 
Use a suitable heat shield material 
to contain sparks or drops of solder. 
Have a fire extinguisher readily 
available. Please follow standard safe 
practices regarding the handling, 
installing or servicing of mechanical 
equipment. 

Read these instructions thoroughly 
and follow all warnings or cautions 
attached to the equipment. Consult 
local building codes for special 
installation requirements.
 
Understand the signal words: danger, 
warning and caution. 

 

Identifies the most serious hazards 
which will result in severe personal 
injury or death. 

Signifies hazards that could 
result in personal injury or death. 

Used to identify unsafe 
practices, which would result in 
minor personal injury or product 
and property damage. 

The manufacturer assumes 
no responsibility for personal 
injury or property damage 
resulting from improper or 
unsafe practices during the 
handling, installation, service or 
operation of the equipment. The 
installation of Induction Units 
and all associated components, 
parts and accessories shall be in 
accordance with the regulations 
of all authorities having 
jurisdiction and must conform 
to all applicable codes. It is the 
responsibility of the installing 
contractor to determine and 
comply with all applicable codes 
and regulations.
