Periodic Maintenance
• Check coolant hoses, clamps, and make sure all valves
are open. Maintain the engine manufacturers recommended
coolant level and ensure that the heater is properly bled after
service on or involving the coolant system.
• Visual check of all fuel lines for leaks. Check and if necessary
replace fuel filter inserts.
• Visual check of electrical lines and connections for corrosion.
• Run your heater at least once a month during the year (for a
minimum of 15 minutes).
• Maintain your batteries and all electrical connections in good
condition. With insufficient power the heater will not start.
Low and high voltage cutouts will shut the heater down auto-
matically.
• Use fuel suitable for the climate. Blending used engine oil
with diesel fuel is not permitted.
In the event of failure there are several items which should be
checked first before any major troubleshooting is done.
Check:
• Fuses.
• Electrical lines and connections
• Interference in Combustion air and Exhaust pipes.
• Fuel in the tank.
• Battery voltage on heater side of harness
• Coolant flow
The heater is equipped with self diagnostic capability. You can
retrieve information on the heaters last 5 faults using the Espar 7
day timer, Espar’s Fault Code Retrieval Device or ISO adapter and
computer.
Espar’s 7 day timer has a fault code
retrieval device built into the unit. This
function automatically activates if the
heater is experiencing problems.
• Fault codes appear on the LCD display screen.
• Codes can then be translated from the charts on the following
pages.
• Pg 10 - 17 for more detailed instructions.
Symbols seen on the display
face are as follows:
AF Actual f
ault.
F1-F5 Up to five stored faults can be accessed.
The AF and F1 are the same.
This sign is displayed when the heater is in operation.
DIAG The word (Diagnostic) will come on when the
diagnostic n
umber is requested.
000 Three digit diagnostic fault code number.
•
Disconnect the main harness from heater and insert adapter
cable harness between them.
• Connect adapter cable to the cable loom of the Fault code
retrieval device.
• Start diagnostic unit - switch heater on from switch.
• Switch the fault code retrieval device on and wait 10 seconds.
• Press the "D" button.
• Wait 3-5 seconds for the current fault code to appear (AF).
• To review the previous faults use the arrow buttons
(F1= Most Recent, F5= Oldest).
• To erase the faults that are in memory press both "L" keys at
the same time.
• See the fault code chart on following pages for code number
descriptions.
