Optional Sleeper Fan Operation
Today’s sleepers are designed for maximum comfort for the vehicle operator. Generally the units are
larger and have accessories that compete for battery power with auxiliary heaters. PROHEAT is a
cost-saving component by reducing fuel consumption and engine maintenance. Therefore, it should
be given priority over these accessories.
For more information on Sleeper Fan installation, please refer to the Installation and Service manual
925830 at www.proheat.com
PROHEAT installation recommendations are designed to allow the operator to:
• Run the PROHEAT with the vehicle ignition key in the OFF position
• Set the desired sleeper ambient temperature using the dedicated Proheat thermostat
The vehicle operator’s responsibility is to ensure that:
• Coolant valves used in the heating system are open: These can be manually or electrically
operated (electrically operated valves must be opened before shutting the vehicle OFF)
• When operating the PROHEAT, power consuming accessories such as refrigerators, DVD’s, TV’s,
satellites, heated mirrors, etc. are not used to ensure enough starting amperage for the engine
• Sleeper curtains are closed: The PROHEAT is designed to heat the sleeper and engine as efficiently
as possible – heating the cab, fuel tanks and batteries means longer run time which will require
more battery power
