Even regular technical maintenance may not completely prevent dirt accumulation
on the regenerator assemblies.
Treat the exchanger with regular cleaning to ensure high heat exchange efficiency.
Clean the exchanger using a vacuum cleaner at least once a year.
Clean the prefilter at least 4 times a year. The user can wash or vacuum the prefilter.
Note that after washing the prefilter, it should be dried and reinstalled in the air duct.
The lifetime of the prefilter is about 3 years. Purchase replacement filters from vendor.

STORAGE AND TRANSPORTATION GUIDELINES
Store the ventilator inside the manufacturer's original packing box in a cool, dry place.
The storage environment must be free of any aggressive vapors and chemical mixtures that
may cause corrosion, insulation, and sealing deformation. Use lifting equipment for handling
and storage operations to prevent ventilator from damage as a consequence of failing or
excessive vibration. Fulfill the handling requirements relevant to the applicable freight type.
Transportation via any type of vehicle is allowed, provided that the ventilator is protected against
mechanical and weather damage.
Take care to avoid any mechanical shocks and sharp ends during handling operations.
