6. Evaporator Assembly - The evaporator assembly is dis-
assembled or reassembled in the following manner:
a) Remove the rear panel of the NAC-600 air conditioner.
b) The evaporator assembly can now be removed from the
NAC-600 air conditioner by the removal of six (6) nuts
located on the extreme right and left hand sides of
the evaporator coil. (Three (3) nuts on the left side;
three (3) nuts on the right side).
c) The suction line coming from t
he lower compartment of
the NAC-600 specifically the compressor which is brazed
to the evaporator suction line tube, must be unbrazed
at the evaporator joint prior to removal of the evaporator.
d) In addition to step (c) above, the distributor, located
in the front of the NAC-600 air conditioner, must be
disconnected from the thermo expansion valve through the
application of a heating torch to unbraze the connection.
e) The evaporator coil is now capable of being removed from
the frame assembly.
7. Thermo Expansion Valve - The thermo expansion valve can be re-
moved or installed through the front of the NAC-600 air condi-
tioner after the front panels have been completely removed from
the unit. The thermo expansion valve is located above the drain
pan and set on the left side of the NAC-600. The disassembly or
reassembly of a thermo expansion valve is accomplished by the
unbrazing of the valve from on (1) copper line below the valve and
