Installation, commissioning and servicing instructions
Function
The 5350 series AutoFill™ automatic fi lling valve is a pressure reducing valve which when installed
on the water inlet piping in closed hydronic systems will maintain system pressure at a set value,
automatically fi lling up with water as required. Fast fi lls the system to set pressure then automatically
shuts off the water feed. This product is factory pre-set to 15 psi system pressure. To adjust the
set pressure, simply turn the adjustment knob while observing the integral dowmstream pressure
gauge. This product has the characteristic of being pre-adjustable, which means that it can
be adjusted at the right pressure value before the system charging phase. After installation,
the system pressure will automatically adjust itself to the set value and the water feed will stop when
the set pressure is reached. The internal cartridge containing all the controlling components is pre-
assembled as a self-contained unit, to facilitate inspection and maintenance procedures.
These items are designed for use in closed hydronic systems. Do not use in plumbing applications.
These items do not meet the low-lead plumbing standards of U.S. and Canada.
