2. Disconnect all external vent lines, motor cooling
supply and drain lines, and oil supply and drain
lines which are connected to the compressor and
compressor motor. Sand all paint off the points
where cuts are to be made. Use a tubing cutter to
ensure that cuts are smooth and square.

reassembling the chiller. Cap open lines to prevent
entry of foreign material.
N N o o t t e e : : Cover all open connections to avoid
prolonged exposure of oil to humid air.
Remove oil if a chiller is kept in a
disassembled condition for an extended time.
