• Perform the checks required by routine maintenance.
• The equipment must be protected against freezing: if it is not possible to protect this way, before starting
it, take it to a warm environment for long enough to melt any ice inside. Failure to do so could cause
serious damage to the equipment.
• If the equipment is used above 1000 m/3281 ft of height, contact a SKILLED TECHNICIAN for a check
and a possible combustion adjustment.
• The use of agricultural, heating or dirt diesel fuel causes excessive deposits onto the burner, thus impairing
its good operation.
• After use, before performing the “STOP” procedure, run the equipment with the burner off for a few
minutes so as to cool down the delivery circuit.
