Install Instructions

MrPEX 1 ¼“ Stainless Steel Manifold is made
from high quality stainless steel, and is oered in
2 through 12 loop conguraons. The manifold
comes mounted on brackets and it is equipped with
full port ball valves provided with thermometers,
manual air vents and ll/drain valves.
The SUPPLY (upper) manifold is ed with balancing
owmeters with readable range of 0 to 2 GPM that
allow ow adjustment of each individual loop. The
ow meters have a brass body and the sight glass is
made from temperature and impact resistant plasc
material, all components are an-freeze resistant up
to a 50% mix.
The RETURN (lower) manifold, has manual on/o
valves that controls the ow for each individual
circuit. The manual knob can be removed to
accommodate the MrPEX actuators (part# 5120700
& 5120701).
Supply and return mains can be connected from either le or right sides. The manifold comes
ready for a le-hand connecon. Connecon from the right can be done by removing the manifold
body from the brackets and ipping them over.
