3.7.1. 

HFC-202 Orifice 

To change the orifice in the HFC-202 Series, turn the instrument upside-down and turn the orifice 
counterclockwise with a 9/64" Allen wrench until it stops coming out. Then grasp the exposed orifice end 
and pull it straight out. See Figure in section 3.7 Prior to reinstallation of the orifice, inspect the two O-
rings mounted on it for damage. Replace if cut or gouged. 
 
Lubricate the O-rings slightly with a silicone-based grease, and the threads with anti-galling compound. 
Push the orifice into its hole and screw it in until it is flush with the instrument base. Apply pressure to 
the inlet side of the instrument. Enable the Valve Override CLOSE function or unplug the instrument. 
Screw the orifice in a few more turns until the flow through the instrument stops, then turn it an 
additional 1/4 turn clockwise.
