The generator shell and some of the machine

piping will become hot during operation. If insula­

tion is to be used as a safety precaution, or to
reduce ambient temperature in the machine room,
we recommend insulating the surfaces shown in
Fig. 9. Hot-surface dimensions are given in Table 3.

Generator insulation can be either blanket-type

or low-pressure boiler insulation. Insulation used

for piping is generally standard low-pressure steam
pipe insulation.

isolation

— 16JB machines are not in themselves a

major source of vibration ; and isolation equipment

is not supplied with the machine unless requested
on the order. It is possible, however, for a machine
to receive and transmit vibrations from other
sources that are imperfectly isolated such as

condensing water pumps, chilled water pumps, or

other piping. Isolation packages are available from
a number of manufacturers. Specifications for

Carrier machines are given in Table 4.

NOTE:
Higher isolation efficiencies may be obtained with double-layer
pads. Double-layer pads, factory-fused together, are available from

various manufacturers. If two single-layer pads are used, a metal
divider equal to pad dimensions should be inserted between iayers.
