VendingMiser
®
is designed to operate as an intelligent power controller for cold product vending machines. Note that
VendingMiser may not be used on any vending machine which contains perishable products.
General Theory of Operation
Using a Passive Infrared (PIR) occupancy sensor, VendingMiser will automatically shut down the controlled vending
machine when the area around it has been vacant for 15 minutes. However, VendingMiser will periodically re-power
the machine automatically to ensure that the vended product stays cold. In addition, VendingMiser contains a current
sensor which determines if the vending machine's compressor is operating and will delay power-down of the vending
machine until the compressor has completed its cooling cycle.
To install the VendingMiser, follow these simple steps:
Prepare For Installation
1.
Unplug the vending machine from the wall outlet. If it is necessary to move
the machine, be careful as it can be heavy.Note-Each vending machine should
remain on the same outlet/circuit breaker at the end of installation.
2.
Remove ALL items from top of the vending machine. Using a clean cloth, care-
fully wipe the area as shown where the VendingMiser will be attached. Ensure the
area is dry when cleaning is complete.
The surface temperature of the back of the
vending machine should be above 65F to ensure the Velcro adhesive adheres prop-
erly to the machine.
Install The VendingMiser
3.
The VendingMiser will be placed on top of rear of the vending machine as shown
below for each model. Carefully remove the white plastic material covering the

adhesive backing on the Velcro. Be very careful not to contact the exposed Velcro adhesive prematurely to the
machine back, as it is very difficult to remove. First place the VendingMiser on top of the vending machine
without the Velcro adhesive touching the machine back, then slide the VendingMiser forward so that the adhe-
sive touches the rear of the machine in your intended placement location. Ensure that the phone cord to the
sensor is not caught under the Velcro, but remains free behind the VendingMiser mounting plate. Press firmly
to ensure good contact.
