SAFETY

THIS PRODUCT IS NOT INTENDED FOR USE WITH TOXIC GASES, FLAMMABLE GASES OR 
CORROSIVE GASES.

Basic safety precautions must be followed to reduce the risk of fire, electrical shock or injury.

·   Connect the IntelliSwitch to the correct line voltage.  A label on the product identifies what voltage it is 

wired for.  CONNECTION TO AN INCORRECT VOLTAGE CAN CAUSE SERIOUS DAMAGE 
TO THE PRODUCT AND WILL VOID ANY WARRANTY.

·   While the IntelliSwitch Switchover is dust and moisture resistant, it is NOT water-proof or completely 

sealed.  It should be installed where it will not be subjected to rain or high concentrations of dust.  Never 
pour or spray liquids directly onto the product.

·   Install IntelliSwitch where the ambient temperature range is between 0° F and 140° F.

·   Do not install this product in a hazardous environment.

· 

If product appears damaged in any way, do not use and request service from CONCOA.

·   Do not attempt to operate the IntelliSwitch with the front panel off.

· 

Consult the cylinder distributor for the proper use of cylinders and for any restrictions on their use (such 
as flow rate and temperature requirements).

· 

Store cylinders with valve caps screwed on, and chain cylinders to a supporting wall or column.

· 

Handle cylinders carefully and only with valve caps screwed on.  The cap will reduce the chance that the 
cylinder valve will break off if the cylinder is accidentally dropped or falls over.  The cap also protects 
the cylinder valve from damage to screw threads, which could cause leaky connections.

· 

All manifolds used with flammable gases should be provided with approved flashback arrestors to stop 
any burning gas in the pipeline from getting back to the manifold or cylinders. 

· 

No smoking should be permitted near oxygen, nitrous oxide, any other oxidizer, flammable gases, or 
flammable mixtures, or in areas where cylinders are stored.

· 

Where an oxidizer (such as nitrous oxide or oxygen) is used, the manifold and cylinders must be kept 
clean.  No oil, grease, or combustible substances should come in contact with oxygen or nitrous oxide 
storage or handling equipment.  Such materials in contact with oxygen or nitrous oxide are readily 
ignitable and, when ignited, will burn intensely.

· 

Never lift gas cylinders with a magnetic lifting device.

· 

Never use an open flame when leak testing. 

· 

Always open valves slowly when high-pressure gases are being used.
