Theory of Operation
Mechanical Installation
Relay Mode
Relay Mode runs pumps for the duration of washing machine supply signals. This mode is typically used
on fully programmable microprocessor controlled washing machines where the installer opts to control
the dispensing equipment from the washing machine control system instead of the dispenser’s control
system. The load counter increments each time pump one is run in Relay Mode.
Wall Mounting Unit
To determine a suitable location to install the dispenser, keep the
following in mind: Install close to product containers at a reasonable
height for easy service access. When intended for Push Button Mode
operation, be sure to allow easy front panel access for the machine
operator.
• Drill one hole in wall for upper mounting bracket screw wall anchor.
• Install wall anchor and temporarily attach bracket to the wall
(do not tighten screw all the way).
• Level bracket using built-in level and mark drill locations for lower
mounting screw holes.
• Swing bracket out of the way, drill lower holes, and install lower
wall anchors.
• Screw bracket into place.
• Lower unit onto wall mount bracket and press down until unit locks
into place. To remove unit from bracket, depress lock button on the
top of the bracket as you lift the unit from the mounting bracket.
Supply and Discharge Hoses
We recommend use of 3/8” ID hose for supply and discharge hoses.
Use of smaller size ID hose/tube may results in reduced flow rates,
premature pump tube failure, or both.
The maximum combined distance for supply and discharge hoses must
not exceed 50 feet. The maximum supply side hose distance must
not exceed 15 feet. The maximum vertical height from product
container to pump must not exceed 10 feet.
Use hose clamps to secure supply and discharge hoses to pump tube
hose barbs. Route supply hose to product pails and discharge hose to
washer per industry standard practices.
CAUTION:
The Mercury dispensing system is
intended to be installed by
experienced installers in
accordance with all applicable
electrical and plumbing codes.
Disconnect power to laundry
machine and dispensers during
installation and/or any time the
dispenser cabinet is opened.
