In the first eight weeks of this first semester course will be a practical hands-on counterpart to the REFG 101 theory class. It will introduce the student to the fabrication of sheet metal air distribution components, iron gas piping, copper tubing, and PVC piping components. The activities will introduce the student to the construction and mechanical skills necessary for the installation of heating, ventilating, air conditioning and refrigeration equipment. REFG 111 will provide actual fabrication tools and equipment where the student will be able to practice fabricating projects until they are acceptable trade quality projects. Sheet metal layout, piping leak testing, threading, priming, gluing, silver soldering, and silver brazing are examples of activities in this lab. Corequisite: REFG 101. (F)
