ISOLATION MOUNTING
The unit is provided with four vibration isolation mounts
consisting of 1" (25.4 mm) thick neoprene isolation pads
for field mounting under the steel mounting pads lo-
cated on the tube sheets.
REFRIGERANT CONTAINMENT
The standard unit has been designed as a complete
and compact factory packaged chiller. As such, it has
minimum joints from which refrigerant can leak. The
entire assembly has been thoroughly leak tested at
the factory prior to shipment. The YORK chiller in-
cludes service valves conveniently located to facili-
tate transfer of refrigerant to a remote refrigerant stor-
age/recycling system. Optional condenser isolation
valves permit storage of the charge in the condenser.
PAINT

bean blue, durable alkyd-modified, vinyl enamel, ma-
chinery paint.
SHIPMENT
The unit shall be completely assembled, with all main,
auxiliary, and control piping installed, controls wired,
leak tests completed, functional run tests completed,
and refrigerant charge in place. The oil charge, relief
device and other miscellaneous materials shall be
packed separately.
Protective covering is furnished on the Control Center
and unit-mounted controls. The entire unit is then shrink-
wrapped with high-quality reinforced plastic to provide
maximum protection during transit. Water nozzles are
capped with fitted plastic enclosures.
