Optimal Performance of the Hanvey Mobile Grooming Van



  • The van should be plugged into the shoreline outlet while the van is not in use for the best life expectancy of both lead-acid and lithium batteries.
  • Charging only by idling and driving is not recommended as the only means of charging the batteries. Operating this way and not plugging in limits the life expectancy of the lead-acid batteries as well as the alternator.
  • Plugging the van in on a daily basis is a requirement for the lithium battery pack, with no exceptions.


Lead-acid Battery Maintenance:

  • Lead-acid batteries are to be filled with distilled water only.
  • The orange fill caps on the batteries are there for your convenience. They show the battery water levels and provide a fill spot. However, they can break and potentially show false “low” levels.
  • Occasionally, removing the fill caps and visually checking the batteries' water level is recommended. The water level should be 1⁄4 inch below the plastic lip inside the holes of the batteries, never into the vent slot.


Electrical System:

  • All electrical outlets in your van have a maximum amperage of 15 amps.
  • The use of dryers and other equipment rated above 15 amps will trip the breakers. Potential damage to the inverter can occur as well as blow the 300 amp fuse. Note the 300 amp fuse is not covered under warranty.
  • Use of ceramic heaters and over 15amp dryers must be plugged into the dedicated (black) plug only.


Hanvey Equipment:

  • All Hanvey equipment within the van is optimized to work seamlessly with the rest of the conversion. This provides optimal power usage throughout the workday.
  • Using non-standard equipment could damage the power system and void your warranty. Caution is advised.


The Tank Warmer:

  • If you empty the fresh water tank or the tank warmer is running dry, unplug the red tape cord from the shoreline breaker box so that you do not damage the heating element.
  • Fill the fresh water tank with water before plugging the van into the shoreline to charge.
  • Once the water is circulating through the tank, wait about 1 minute and then plug the red tape cord into the shoreline breaker box.


Optimum A/C performance:

  • Keep the A/C running at high speed as often as possible, with minimum use of “low” and “medium” speeds.
  • Vents can be adjusted or closed as needed for comfort.
  • The heater can be run at the same time to normalize the temperature if it's too cold.


Mercedes Emissions System:

  • Idling for long periods at one location beyond two hours is not recommended.
  • Routinely check the Diesel Exhaust Fluid (DEF) level. A sensor is on the dash. It is not recommended to allow DEF to fall below half. When filling DEF, always fill it completely to reset the sensor.
  • Monitor the Diesel Particulate Filter (DPF) daily. If it hits 100%, make sure it completes a regeneration cycle before turning off the vehicle.


Conversion Maintenance:

  • The conversion is designed to be user serviceable. QR codes are throughout the grooming area to aid in maintenance and repair.
  • When in doubt, a handyman is a useful helper to have on a retainer.
