1. SAFETY INSTRUCTIONS 
 
 
A.  Keep this instruction booklet where it can always be easily consulted by the 
operator or by maintenance personnel. 
B.  Warning:  hot components may be inside the plastic housing of the controller. 
C.  No user-serviceable parts are inside the plastic housing of the controller. 
 
D.  The controller and any device connected to it must be installed in compliance 
with the Safety Regulations in force. If these regulations are not respected 
during installation, and if our product is not installed in compliance with the 
indications given in this instruction booklet, then this may cause a reduction in 
the safety level of the controller. In particular, the ambient operating conditions 
for the controller given in our technical data must be complied by; absolutely 
avoid: water condensation or excessive humidity, exposure to steam, 
corrosive - or toxic gases, contact with any type of liquid, and exposure to 
shocks or to extreme vibrations. Not respecting the above indications could 
cause malfunctions and entail unpredictable consequences, e.g., in the worst 
cases, dangerous electrical discharges on probes or other parts of the 
instrument.      
 
E.  This controller is guaranteed by Honeywell to have a specific immunity level, 
in compliance with CE regulations, against irradiated and conducted 
electromagnetic disturbances. By irradiated electromagnetic disturbances we 
recommend to screen the controller with a metal screen connected to ground. 
To eliminate, or at least reduce conducted disturbances, which not only could 
propagate through the mains but also through the probes or the connected 
loads, carry out the electrical wiring according to the indications given in this 
instruction booklet. If necessary, use filters with suitable characteristics for 
specific applications and for the detected type of disturbance. 
 
F.  If the type of probe to be used will directly touch foodstuffs, make sure that it 
is in compliance with the local sanitary and health regulations.  
 
G. The controller has no type of protection for the connected loads, so these 
must be protected against short circuits, over-current or over-voltage, 
excessive temperature, etc., by suitable protective means (such as fuses, 
suitable thermo-magnetic circuit breakers, thermal protections, etc.). At any 
rate, the electrical power lines that supply both the controller and any other 
device connected to it, either directly or through a transformer, must be 
manufactured in compliance with the regulations in force.  
 
H. When the controller is used in appliances where any malfunction of said 
controller could cause a form of risk to persons, animals or things, it is 
ABSOLUTELY MANDATORY to provide a suitable protective/safety device, in 
addition to the controller, which independently starts to operate in case of a 
failure.  
 
I.  The controller cannot be used as a critical component in life-support devices 
or systems without a written approval expressly issued by the legal 
representative of Honeywell.  
 
 CAUTION   
Disconnect the power supply before you begin installing the Icon controller. Do 
not reconnect the power supply until you have completed installation.
