opened. Do not replace the Drier until after all other repair or replacement
has been made.

install the new Start Capacitor and Start Relay supplied with the re
placement Compressor. Due to the ability of the POE oil in the com-
pressor to absorb moisture quickly, the Compressor must not be
opened more than 15 minutes for replacement or service. Do not mix
lubricants of different compressors even if both are charged with
R-404A, except when they use the same lubricant.
