Proheat X45–School Bus - Manual (Page 6)

This manual is provided to assist an authorized PROHEAT
dealer to install and service a PROHEAT heater. Although
trucks have been used in the examples, applications for
PROHEAT are by no means limited to trucks. PROHEAT
heaters are designed to be used on any diesel equipped
vehicle including: trucks, buses (school, transit and coach),
construction equipment, off road equipment, military
equipment and cargo.
PROHEAT heaters are used in the following applications:
(1) Engine Block Heat – PROHEAT will preheat an engine
block to ensure reliable starting in cold weather. At
the same time it may be used throughout the year to
reduce the wear associated with cold starts.
(2) Cab or Sleeper Heat (engine off) – PROHEAT will supply
heat to the cab or sleeper. Drivers can sleep in comfort
not only in the cold of winter but also in the spring
and fall when the weather is miserable. Substantial
savings through reduced fuel consumption and engine
wear can be obtained by not idling the engine.

(3) Supplemental Heat (engine running) – as the efficiency
of modern diesel engines are improved there is no
longer adequate reject heat available to heat the
vehicle’s interior. This is particularly true for buses.
PROHEAT can be used while the vehicle is operating
to provide supplemental heat for the interior.
(4) Cargo Heat – PROHEAT can be used to provide heat to
protect valuable cargo such as produce or beverages
from damage due to freezing.
(5) Marine – Marine applications typically involve the
engineering and installation of a complete hot-water
heating system of which PROHEAT is only one
component. Proheat recommends that only an
expert in marine hot-water heating systems install a
PROHEAT on a boat. It is the installer’s responsibility
to ensure that the installation complies with all
applicable regulations.
