(38 mm) diameter holes located on the machine base assembly that provide for optional,
customer-supplied anchor bolts.
Springs are shipped separately on machines ordered with spring isolation. Specific details on
spring mounting and machine weight distribution should be obtained from your individual job
data.
At the time of installation, the 19FA machine has refrigerant in excess of 2000 lb (90 kg) in
the integral storage tank. This refrigerant is redistributed throughout the machine at initial start-
up. To avoid damage to machine and piping, spring isolators must remain blocked until machine
is started.
