5. Install air line (3/8 in. (76 mm) ID minimum)
with quick disconnect air coupler (56).
Connect a grounded fluid hose (AH) to the
1/2 npt(f) fluid outlet (AL). In a circulating
system, remove the pipe plug (2) and con-
nect a fluid return line to the 3/8 npt(f)
return port (AM).

3. Fluid hoses: use only grounded hoses with
a maximum of 300 ft (91 m) combined hose
length to ensure grounding continuity.
4. Dispensing valve: grounding is obtained
