3.6 PRECAUTIONS DURING BRAZING OF LINES

All outdoor unit and evaporator coil connections are copper-to-copper and should be
brazed with a phosphorous-copper alloy material such as Silfos-5 or equivalent. DO
NOT use soft solder. The outdoor units have reusable service valves on both the liquid
and suction vapor connection. The total system refrigerant charge is retained within the
outdoor unit during shipping and installation. The reusable service valves are provided
to evacuate and charge per this instruction.
Serious service problems can be avoided by taking adequate precautions to assure an
internally clean and dry system.
