Refrigeration System Repair

The following paragraphs cover repairs of commonly used hardware, tubing and valves of the refrigeration system.

Re-use or repair of seals and gaskets should not be attempted; new parts should be used at assembly. When heating

refrigeration piping to debraze or unsolder connections (see work package WP 0046 00) as well as to solder or braze

them, the piping should be protected with a continuous flow of dry nitrogen to prevent scaling or oxidation of the

inside surface.

Replace the filter-drier each time a repair is made on the refrigeration system or each time the refrigeration system

has been opened.
