When the valve stem is not pushed forward or pulled back
completely, the valve is in “Mid Position,” as shown in
CAUTION
Do not operate the system with the three-way valve stem in the
Mid Position.

Field Insulation
If the optional factory installation of thermal insulation is not
ordered, insulation should be field installed to reduce heat loss
and prevent condensation from forming. Insulation should cover:
•
the evaporator barrel, tube sheet, and waterboxes.
•
the suction line from the top of the evaporator to the
compressor inlet flange.
•
the compressor support brackets welded to the evaporator.
•
the liquid line from the expansion valve to the evaporator
inlet, including the expansion valve.
•
the part load balance valve to the evaporator.
Approximate total square footage of insulation surface required
for individual packaged chillers is tabulated by evaporator code
and can be found in
