Storing
WARNING!
To prevent damage to the MVS, keep the delivery packaging and protection canvas
on until you install it.
• Always store the MVS in upright position.
• Avoid opening the doors unnecessarily and remove the transportation plates during
storage and at the time of installation.
• If removing the MVS from protective packaging and if condensation is possible in the
storage area, follow the below conditions:
• Supply power to the internal heaters to maintain the inside temperature of the unit
more than the outside temperature.
• If power supply is not available, add humidity desiccant bags inside the station.
• If the MVS is stored for more than two weeks without using electric heaters, use
desiccant bags. See also,
Conditions for using desiccant bags (page 28) .
• Make sure the ground underneath the MVS is solid, flat, dry and vegetation-free. The
ground must support the station evenly from below and there should not be any twisting
or stress. Do not place the MVS directly onto the bare ground because this could damage
the paint and cause corrosion.
• Place the MVS on wooden support beams. Locate the beams under the four corners
and the middle points.
￭ Conditions for using desiccant bags
• Hang the desiccant bags approximately 1 m from the floor.
• Use 500 grams of desiccant per week. For example, for four weeks of storage, use 2
kg of desiccant bags.
• Replace the bags with fresh bags every four weeks.
• Do not open the doors unnecessarily during the storage period.
• Examples of suitable container desiccants: Xdry desiccants “H model” or Clariant
“Container Dri®II- Pole”.
Note: The MVS is delivered with desiccant bags from factory as standard.
