Installation 

 

 

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 

 

 

 

Take measures to prevent people from coming into direct contact with 

product outlets. Failure to do so may result in burns or other injury from 

the discharge of fluids.

 

CAUTION 

 

Installation, inspection, maintenance, repairs, disassembly, adjustment and valve 
opening/closing should be carried out only by trained maintenance personnel. 

 

1.  Before installing the product, open the inlet valve and blow out the piping to 

remove any piping scraps, dirt and oil. Close the inlet valve after blowdown. 

2.  Before installation, be sure to remove all protective seals. 

3.  Install the product so the arrow on the body is pointing in the direction of 

condensate flow. 

4.  The product may be installed either horizontally or vertically; there are no 

restrictions on the orientation of installation. However, when installing 
horizontally, make sure that the product is installed with the temperature adjusting 
screw positioned higher than the piping in which the product is installed. (Upside-
down installation is not permissible.) 

5.  Open the inlet valve gradually and check to make sure that the product functions 

properly. 

 

 

If there is a problem, determine the cause using the “Troubleshooting” section in 
this manual.
