CROSSOVER PIPING IS AVAILABLE FOR A, H AND D COILS. FOR ALL D (4-PIPE) COILS, TRANE
PROVIDES THE CROSSOVER FOR THE COLD WATER ONLY. THE CROSSOVER PIPE IS FACTORY INSULATED
WITH 3/8"-THICK INSULATION.
EXPANSION COMPENSATION BETWEEN THE FACTORY PIPING PACKAGE AND THE CROSSOVER
PIPING IS ACHIEVED USING A FLEX HOSE RATED AT 250 PSI WORKING PRESSURE. FLEX HOSE
IS ONLY AVAILABLE WITH FACTORY MOUNTED PIPING PACKAGES.
EXPANSION COMPENSATION FOR THE CROSSOVER PIPING MUST BE HANDLED EXTERNAL TO
THE UNIT VENTILATOR.
CROSSOVER CONNECTIONS TERMINATE IN THE SAME END POCKET AS THE MAIN COIL CONNECTION.
THE MAIN COIL CONNECTION FOR 2-PIPE SYSTEMS IS THE HEATING COIL. THE MAIN COIL CONNECTION

Installation Crossover Piping
Crossover piping is available for A, D
and H coils. It is either 1 3/8’’ \[34.9\] or
2 1/8’’ \[54\] in diameter (O.D.) as speci-
fied by the customer. Crossover piping
can be found in either the left or right
hand end pocket.
See Figure 26.
On D style coils, crossover piping con-
nects to the main cooling coil.
Factory insulation is provided on all
crossovers.
When a Trane piping package is
ordered, it is installed with the connec-
tions made to the supply and return of
both the coil and the crossover piping.
However, supply and return connec-
tions must be made in the field when a
piping package is furnished by the
installer.
The crossover piping is located at the
back of the unit along the wall and the
ends of the piping are flush with the
end of the unit.
Expansion compensation
between the piping package
and the crossover piping is
achieved using flex hoses
rated at 250 psi working
pressure. Expansion com-
pensation for the crossover
piping must be handled
external to the unit ventila-
tor.
