Test for leak
• Pressurize the refrigerant lines and
evaporator coil to 350-400 PSIG using dry
nitrogen (Fig. 19). The nitrogen pressure
must be maintained for few minutes.
• If pressure decay is observed,
it is an indication of leak(s).
• Check for leaks by using a soap
solution at each brazed joint (Fig. 20).
6.3.5 Refrigerant Line Insulation
• The Vapor Line must always
be insulated (Fig. 21).
• DO NOT allow the liquid line and
vapor line to come in direct (metal
to metal) contact to each other.
