Battery charger manual

For posterity, here’s the service manual for the battery charger that’s installed in our Westies:

Airstream Sprinter Westfalia battery charger manual

The info comes from OldFool / OldWest, who posts in the Yahoo group as well as on

According the the Samba thread, the battery charger was manufactured by Cherokee Europe for Westfalia. Cherokee Europe was purchased by its management in 2008 and became Mitra Energy and Infrastructure with a website That name later became Mitra Innovations. Mitra Innovations is now part of Alpha Technologies.

(Here’s the thread.)

If you’re looking for the location of the charger in your van, it’s behind a metal plate in the cabinet under the kitchen sink.

Espar heater documentation

A collection of manuals and troubleshooting documents for the Espar heaters that are installed in the Sprinter. There are two separate heaters installed from the factory:

  • An Espar Airtronic D4S that provides coach heat. It’s installed in a metal box underneath the van, on the driver’s side. You’ll recognize it by the exhaust coming out of the box. This is an extra heater, installed as part of the Westfalia conversion.
  • An Espar Hydronic D5 that provides coolant heating and ‘booster’ heat. It’s also referred to as the ‘auxiliary water heater’ in the owner’s manual. Engine coolant is circulated through this heater when it is activated, speeding up engine warming and providing hot cabin heat more quickly.
There’s also a residual heat option (the REST button on the dash) that circulates coolant past a fan. It blows any residual heat from the coolant, providing cabin heat for a time after the engine has been turned off.
D4S manuals:
D5 manuals:

More information can be found in this (still rather confusing) post on

The owner’s manual also provides information on operating the booster/auxiliary water heater.

There are four parts to the manual:
