Setup
Electrical connection
Gas connection
▪ Prior to starting the installation work, notify any operators present about
the procedure.
▪ Prior to starting the installation work, discuss how to behave in an
emergency.
▪ Use equipment and protective gear suitable for the activity.
▪ Brace housing components to prevent them from falling over and
dropping.
