Distributed Pumping System
A distributed pumping system con-
tains either a single or dual pump
module, specifically sized for each wa-
ter-source heat pump, then connected
directly to the units supply and return
lines.
The distributed system’s supply and
return lines should be sized to handle
the required flow with a minimum
pressure drop.
Hose kits
are used to connect the
water supply and return line to the
water inlets and outlets. Trane of-
fers various hose kit combinations
to better facilitate system flow bal-
ancing. These flexible hoses also
aid in the reduction of vibration be-
tween the unit and the rigid central
piping system.
The unit’s (item 2) 3/4-inch
high
voltage
and (item 3) 1/2-inch
low voltage
connections are
located on the left chamfered
corner of the unit. They are de-
signed to accept conduit.
A field supplied
line voltage dis-
connect
should be installed for
branch circuit protection. Check lo-
cal codes for requirements.
Trane’s self-contained
pump
module
and
hose kit
make a
complete pumping package for
distributed pumping systems.
The module is designed for circu-
lating commercial loops that re-
quire a maximum flow rate of 20
gpm. Each pump module is ful-
ly assembled for connec-
tion to water and electrical
points. The kit contains all
of the necessary compo-
nents for the installation, operation
and maintenance of a closed loop
application. See WSHPC-IN-5
(72-9006-03) for electrical and di-
mensional requirements
The distributed pumping system
supply and return lines
should
be sized to handle the required
flow with a minimum pressure
drop.
Note: Pipe will sweat if low tem-
perature water is below the dew
point of the surrounding space.
Trane recommends that these
lines be insulated to prevent dam-
age from condensation when con-
denser loop is designed to be
below 60 F.
For acoustically sensitive areas, a
six-inch deep
fiberglass insula-
tion
is recommended to be field
installed below the horizontal unit.
This field supplied insulation
should be approximately twice the
footprint size of the unit. It pro-
vides sound damping of the unit
while in operation.
