Operating instructions

Initial Operation

After the heater has been installed, the water circuit and

the fuel supply system must be thoroughly bled. When so

doing, the vehicle manufacturer’s instructions must be ad-

hered to.

During a test run of the heater, all water and fuel connec-

tions must be checked for leakage and security. Should

the heater shut down during operation, troubleshooting ac-

tivities must be carried out.
