Full Product Manual

Thermostatic Flow Setter Valve
Each radiator is equipped with a thermostatic flow setter valve installed. This valve incorporates two elements; a manually adjustable flow balancing valve and a
temperature control. When an optional A40400A thermostatic operator is installed (sold separately), the flow rate of the water and therefore the heat output of the
radiator will automatically be controlled. If the optional thermostatic operator is not installed the white decorative knob supplied with the radiator must be left loose
to provide unrestricted water flow through the radiator. The balancing function can be adjusted by turning the white portion of the valve stem and aligning a number
on the scale with the position indicator located on the brass portion of the valve. See percentage scale below.

Pensotti Snap Grip mounting brackets must be securely fastened to the wall. Frame type construction
requires that the brackets be fastened to the wall studs, preferably evenly spaced and toward the ends of
the radiator. Each set of mounting brackets includes 2 masonry wall anchors, these are NOT to be used as
hollow wall anchors in frame type construction applications.
Install the brackets, aligning the bottom with the desired height of the radiator bottom; a minimum of 4” is
required. Plumb the brackets against the wall and mark the hole locations. Drill pilot holes and install the
screws, do not tighten, hang the brackets from the screws then tighten completely. Extend the top clamp
by pulling the clamp lock away from the bracket slightly and lifting the clamp. Lift the radiator and fit the
rear bottom edge into the bottom seats. Tilt the top of the radiator towards the wall, when plumb, push
the top retaining clips down into the radiator grill until a click is heard. A screw on the top of the retaining
clamp permits minor adjustments if necessary. Additional bracket sets are available if required.
Pensotti panel radiators can be connected directly to a piping system using the
available PEX tubing and copper pipe adapters (see Page 1). Two adapters are
required per radiator. Isolation by-pass valves are available and installed between
the A55400T reducers and Pex tubing and/or copper pipe adapters.
PEX Connections:
Insert the A55400T reducers into the supply and return connections of the radiator
and tighten with a 12mm allen wrench. Slide the 3 piece Pex adapters onto the
proper size tubing, nut first, then compression ring and lastly the O-ring insert. Slide
the end of the tubing into the A55400T reducer completely and hold it. Slide the
adapter nut and compression ring along the tubing and tighten onto the A54400T
reducer. Do not overtighten.
Copper Connections:
The A431-1/2”C copper pipe adapter is one piece. Install it on the ½” copper pipe
compression ring end first. Slide the end of the copper pipe into the A55400T
reducer completely and hold it. Slide the copper adapter nut along the pipe and
tighten onto the A55400T reducer. Do not overtighten.
All fittings are sealed using integral O-rings. Pipe thread sealant is not required.
A thermostatic operator is easily installed on the
thermostatic flow setter valve. Simply, turn the setting on the
operator to #5, remove the white cap from the thermostatic
flow setter valve and screw the operator onto the valve
completely. Set the operator to the desired temperature
using the table to the left.
