Page 9: Placement Of Multiple Units Next To Each Other
Placement of multiple units next to each other Depending upon the temperature and humidity at the installation location as well as the correct values being set, water contained in the surrounding air may condense on the surface of a refrigerator (condensation formation) due to the design. If multiple refrigerators or freezers are placed next to each other, then this condensation effect is stronger, plus a smaller amount of air would then circulate between the units. -

Page 13: Water Connection
Water connection To provide proper steam production, the humidifier must be connected to a water supply. To assure ideal steam production, it is important that the electrical conductivity of the inlet water is measured by the installer, to assure it is within standard range. See Below Box! Please note the following: The electrical conductivity of the water must be in the range: 200-800 µS/cm.* The temperature of the inlet water must not exceed 40°C. -
Page 14: General Use
General use Do not block vent holes in the front panel. Do not damage the refrigeration system parts.
