Install Field Insulation
Apply insulation as specified in the job data and Figure 26. If the pressure gage reading
(above) indicates a significant loss of the 10 psig (68 kPa) holding charge, the machine may
require dehydration. Do not apply insulation before dehydration.
Standard factory insulation covers the compressor motor shell, motor end cover, motor
cooling line, and refrigerant drain from the compressor. Field coverage may include the
compressor suction housing and suction elbow, flash economizer, and the cooler. The
approximate square footage required for insulating this area is given in Table 3. When
