When connecting the GMU discharge line to the
make-up line of the Closed-loop system the 3/4" NPT
fitting needs to be tightened. When doing this, be
sure to use a back-up wrench on the fitting. Do not
over tighten the fitting. Inspect all visible fittings for
leaks. Tighten the fittings if any leaks are found. Be
sure to use two wrenches one to tighten the fitting
and the other to back-up the fitting. Using just one
wrench may damage the fitting. Never tighten a fitting
while there is hydraulic pressure in the fitting.
Support the discharge line independently by use of
pipe hangers or anchors. Do not attempt to spring
the discharge line into position. It is recommended
that there is a three (3) valve by-pass in the make-up
line. See drawing 1FC008 for location of valves.
IMPORTANT: Do not install and operate pumps
in closed systems unless the system is constructed
with properly sized safety devices and control
devices. Such devices include the use of properly
sized and located pressure relief valves, compression
tanks, pressure controls, temperature controls and
flow controls as appropriate. If the package includes
a pressure relief valve, make sure the discharge of
the valve is directed to the floor drain before making
the unit operational.
WARNING: The heating of water and other fluids
causes volumetric expansion. The associated forces
may cause failure of system components and release of
