CAUTION

Hansen Gas Detection Sensors, Monitors and Aler t 
Systems have been designed for refrigeration systems.  

These  instr uc tions  must  be  completely  read  a nd 

understood before selecting, using or servicing Hansen 
valves.  Only knowledgeable, trained refrigeration 
mechanics should install, operate, or service these valves.  
Stated temperature and pressure limits should not be 
exceeded.  Bonnets, solenoid tubes, etc. should not be 
removed from valves unless system has been evacuated 
to zero pressure.  Must also see Safety Precautions in 
current List Price Bulletin and Safety Precautions Sheet 
supplied with product.

WARRANTY

All Hansen products, except electronics, are guaranteed 

against defective materials or workmanship for one 
year F.O.B. factory.  Electronics are guaranteed against 
defective materials or workmanship for 90 days F.O.B. 
factor y.  No consequential damages or field labor is 
included.
