Installation - Direct Expansion Coil Piping (Optional)
IMPORTANT!
Guidelines for the installation of direct expansion cooling coils have been provided to ensure proper
performance and longevity of the coils. These are general guidelines that may have to be tailored to
meet the specific requirements of any one job. As always, a qualified party or individual should
perform the installation and maintenance of any coil. Protective equipment such as safety glasses,
steel toe boots and gloves are recommended during the installation and maintenance of the coil.
IMPORTANT!
All field brazing and welding should be
performed using high quality materials and an
inert gas purge (such as nitrogen) to reduce
oxidation of the internal surface of the coil.
IMPORTANT!
All field piping must be self-supporting and
flexible enough to allow for the thermal
expansion of the coil.
