Specifications 

 

 

Install properly and DO NOT use this product outside the recommended 

operating pressure, temperature and other specification ranges. 

Improper use may result in such hazards as damage to the product or 

malfunctions which may lead to serious accidents. Local regulations 

may restrict the use of this product to below the conditions quoted.

 

CAUTION 

 

 

 

DO NOT use this product in excess of the maximum operating pressure 

differential; such use could make discharge impossible (blocked).

 

CAUTION 

 

 

 

Use only under conditions in which no freeze-up will occur. Freezing 

may damage the product, leading to fluid discharge, which may cause 

burns or other injury.
