While we make every effort to ensure that all components are included, it is a good idea to check that none are missing prior to
arriving at the installation location. In the unlikely event that a part is missing, please call 800-438-1524 with information from the
end of the box and the assembler’s name. We will provide same-day shipment of the replacement part.
NOTE: Please read these instructions completely before beginning, as some of the later steps are affected by earlier steps.
This Backside Vertical System was developed for use in Steinway uprights, player pianos, Disklaviers, and any other vertical where
the bottom front cavity is so narrow it will not accommodate a standard Humidifier. With this System, two small Humidifiers are
joined by means of a large diameter tube. As one Humidifier is being filled, it drains into the other Humidifier until the levels in both
Humidifiers are the same. Throughout usage, the water level in both Humidifiers will remain the same. The low water warning light
will blink when the level in both Humidifiers drops below the sensor probes located in just one of the Humidifiers. There is just one
watering tube for the interconnected System.
