Player Piano Electric Vacuum Motor/Suction Box,Play/Rewind Volume Ctrl DS2-120

Description

Brand new suction box with completely independent control for play and rewind, model DS2-120, installation instructions and tech support included. Unlike some controls from the past the volume knobs are truly independent - neither has an effect on the other.  One control is set for play, the other for rewind (this way you can independently control the volume during play and the speed at which the roll rewinds afterwards). There is a trim potentiometer to set minimum suction level (we set it during testing but it can be adjusted as needed). Suction box measures 7 5/8" square, about 11.5" tall. Powerful, pulls up to 70" water vacuum. 1 1/4" main connector, 1/2" connector for accessories like auto rewind (available in our eBay store). Internal check valve so foot pump operation is not affected. Two stage motor, 120 volts AC, 7.7 amps, auto thermal protection, grounded. Includes 2' of flexible hose, brass connector, 6' power cord, play/rewind microswitch, control box and hardware (wire nuts, screws, cable clamps) included.
Fairly straightforward installation.  Select a location to drill a 1 1/4" hole to install included brass connector (this is usually in a reservoir, not one of the bellows that is connected to the pump pedals (care needs to be taken to avoid any internal springs) - if in doubt send me a pic of the foot pump mechanism and I'll be glad to make recommendations).  Pick a convenient location for the box housing the control knobs and install using included hardware, pick a location and install the switch that senses play/rewind (it's connected to a lever or rod that moves when the player is switched between play and rewind - this is how the system knows which suction level (as determined by one of the two knobs) to use.  Wiring harness is color coded - connect same colored wires via the included wire nuts. Ready to ship, goes out the same day when purchased before 2pm CST (Mon-Fri). This suction box is designed internally to limit transmission of vibrations from the motor to the box and it is felted on the bottom to help prevent noise transmission from the box to the piano. I get asked sometimes if this pump will work for a player that is not working.... If the piano isn't playing at all with the foot pumped bellows I doubt this pump will help.  This pump will work well for pianos that are somewhat to moderately leaky - 70" is a LOT of suction.  If it plays when you pump the foot pedals, even if you have to pump pretty fast, this suction box should help.  My "test player" is a piano that was probably restored 40 years ago, is a very leaky hard to pump player, and this box works for it.  It would certainly play better if it were completely restored, but for now....
We also now offer the flap style auto shutoff spoolbox switch with installation instructions - item #
