6.5 RECOMMENDED SPARES REQUIREMENTS
Emergency parts recommended to be kept on site
The following components are recommended to ensure fast recovery times in the event of a heater compo-
nent failure. An engineer attending a breakdown on site can immediately use the contents of the 1st aid kit
to make a rapid repair. Once a component is used it must be replaced at the earliest possible opportunity to
ensure rapid breakdown recovery abilities are retained.
