11 Acceptance and Commissioning
Before commissioning, the heating system must be checked by an authorized Webasto
®
partner! Charges are liable for the acceptance.
The following commissioning instructions apply only for authorized Webasto
®
Partners:
• With a do-it-yourself installation by customers: Check the heating system for correct
installation, if necessary, rectify installation faults.
• Only put completely installed heating systems into service.
• Carefully bleed the water circuit and
fuel supply system.
• Fill the water circuit at the lowest possible position (avoiding air pockets).
• Bleed thoroughly at the highest point of the heating circuit (for high efficiency ad to avoid
corrosion)
• Open bleed valves after one another, switch on the heating system briefly, then bleed
again. If no more air escapes: let the heating system run for longer. If the heat
exchangers heat up very quickly: there is no water circulation. Turn off the heating system
and bleed again.
• Turn the heating system on again and check the system for water output. Always ensure the
fluid level is sufficient. After filling and pressure testing the heating circuit, carefully bleed the
heating elements and convectors.
• Open systems: static bleeding.
• Test run the heater: check all water and fuel connections for sealing and security.
• If there are any fault messages during operation: troubleshoot.
• Type plate/duplicate type plate easily readable. Record the year of first commissioning.
12 Operating instructions
• Before switching on the equipment, check that the on-board ducts are free of exhaust
gasses.
• The heating system must be turned off while refueling.
• Do not operate in enclosed areas, e.g. in the shipyard.
• Set the adjustable heat outlets so that they do not blow hot air directly onto living
beings or temperature-sensitive objects.
• The area around the heater must be kept clear. Do not store easily flammable /
temperature-sensitive articles such as fuel containers, oil cans, spray cans, fire
extinguishers, cleaning cloths, clothing, paper, sails, fenders etc. on/near heaters or allow
them to come into contact during rough sailing.
• On fuel loss: repair the damage immediately. Until it has been repaired, do not use the
heater again.
