1.0 THEORY OF OPERATION
The Mercury offers four operating modes for
maximum flexibility in small OPL and Top Load
washer laundry applications. Automatic Formula
Selection may be used in all modes whenever a spare
washer supply signal output is available that may be
programmed to the second. The following sections
describe each mode’s unique operation specifications
in detail.
1.1 Automatic Mode
Automatic Mode is a basic mode of operation similar
to Timer Mode in our Eclipse and Orion dispensers.
Each trigger signal input number matches the
corresponding pump number (i.e. trigger 1 = pump
1, trigger 2 = pump 2, etc.). Pumps can be delayed
after trigger signals for occasions where pump delays
are required to prevent dosing on dry linen, etc.
Pump delay times are programmable in seconds.
Pumps 1 and 2 have two product levels, A and B.
The A level dispenses on the first occurrence of the
trigger signal in a formula. The B level dispenses on
the second occurrence of the same trigger signal
within the same formula. Pump 3 only has one
product level.
The Pump Lockout feature, when turned on, prevents
any unwanted pump activations due to false signals
from washers that send noisy or multiple output
supply signals.
Loads are counted each time the highest pump
number with an amount programmed (unique to each
formula) is run. The Pump Lockout timer and
(pumps 1 and 2) A/B levels will be reset 5 minutes
after the count pump runs or the Lockout period
ends, whichever comes first. If the load needs to be
restarted for any reason, the dispenser wash formula
may be terminated early by pressing the Enter key
for two seconds.
1.2 Push Button Mode
Push Button Mode is intended for manual operation
where the machine operator selects a formula and
presses the Enter key to start and run the dispenser
wash formula. A dispenser wash formula consists of
up to 5 programmed pump amounts (1a, 1b, 2a, 2b,
and 3 are the five programmable pump amounts from
three physical pumps). Pump Delay times (programmed in minutes) stagger the programmed pump
doses throughout the wash load.
The Pump Lockout feature (programmed in minutes)
prevents the machine operator from starting multiple
doses in the same wash load. If the load needs to be
restarted, the dispenser wash formula may be
terminated early by pressing the Enter key for two
seconds. Loads are counted each time the highest
pump number with a programmed amount is run.
1.3 Occurrence Mode
Occurrence Mode paces the dosing of products off
the washer fill valves by counting each time the
machine fills to identify the occurrence-sequence of
machine steps. This mode of operation is ideally
suited for machines with no chemical supply signal
outputs, such as domestic style top load washers.
While all three of the trigger signal inputs are active
and may be used, typically only two will be used.
Typical trigger signal wiring would be one of the
available trigger signal inputs wired to one fill valve,
and another trigger signal input to the other fill valve
(typically the hot and cold fill valves). Since the
dispenser responds to any of the trigger inputs, it
does not matter which input goes to which fill valve.
The dispenser counts the machine fill occurrences
and runs pumps based on an assignment of the
pumps to the machine step sequence.
Note: Careful attention must be paid when
programming the signal Filter
Duration time to account for any
spurious fills resulting from level
and/or temperature controls in the
washer. For more information, please
see section 4.8, Filter Duration.
A dispenser wash formula consists of up to 5
programmed pump amounts (1a, 1b, 2a, 2b, and 3
are the five programmable pump amounts from three
physical pumps). Any of these available amounts
may be programmed to any (up to 9) machine step.
The Lockout feature is available to be sure that each
programmed pump amount only runs one time per
dispenser wash formula. The dispenser wash formula
is terminated 5 minutes after the last pump programmed in a sequence runs, or the Lockout period
(when on) ends, whichever comes first. If the load
needs to be restarted for any reason, the dispenser
wash formula may be terminated early by pressing
the Enter key for two seconds.
1.4 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.

2.0 MECHANICAL INSTALLATION
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 all laundry
machine and dispensers during
installation and/or any time the
dispenser cabinet is opened.
2.1 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.
2.1.1 Drill one hole in wall for upper mounting
bracket screw wall anchor.
2.1.2 Install wall anchor and temporarily attach
bracket to the wall (do not tighten screw all
the way).
2.1.3 Level bracket using built-in level and mark
drill locations for lower mounting screw holes.
2.1.4 Swing bracket out of the way, drill lower
holes, and install lower wall anchors.
2.1.5 Screw bracket into place.
2.1.6 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.
2.2 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.

3.0 ELECTRICAL INSTALLATION
The Mercury is available in two different wiring
versions: terminal block, or wiring cable. The
following instructions apply to cable versions.
Terminal Block versions include an additional wiring
information label adjacent to the terminal blocks
inside the unit enclosure.
The Mercury includes two separate wiring cables for
Main Power and Input Trigger Signal connections.
These cables may route through either one or two
conduit fittings, as required.
CAUTION: The Mercury dispensing system is
intended to be installed by experienced installers in accordance with
all applicable electrical and plumbing
codes. All laundry machine and
dispenser power is to be disconnected
during installation and/or any time
the dispenser cabinet is opened.
CAUTION: Always verify all voltage sources with
a meter.
NOTE: Failure to use watertight conduit for
electrical cables will impair water
resistance of the unit enclosure.
3.1 Main Power
Main Power is a universal power input that accepts
any AC voltage from 90-249 VAC, 50/60 Hz. Typical
sources include a wall outlet, or washing machine
incoming power terminals. For wall outlet connections use a wall plug, sourced locally, that fits outlets
in your region.
Main Power Cable color coding is as follows:
Blue + Brown 90-249 VAC, 50/60 Hz.
NOTE: In cases where a Neutral wire exists,
connect Neutral to
the Blue wire.
Green with yellow stripe is Earth Ground.
3.2 Trigger Signal Wiring
All trigger signal inputs are optically isolated high
impedance input circuits. Washer supply signal
voltages may range from 24-249 VAC, 50/60 Hz
(20 mA maximum draw) or 12-24 VDC
(5 mA maximum draw) that accommodate the range
typically found in most washing machines.
Each signal input connects to a pair of signal input
wires (solid color and white with colored stripe).
In cases where the washing machine has a single
common for supply signals, connect all the signal
input common wires (white with colored stripes) to
the machine's signal common wiring location.
In Automatic or Relay Mode trigger inputs match
pump numbers (i.e. trigger 1 = pump 1, etc.).
In Occurrence Mode connect wire pairs from each
machine fill valve to two trigger inputs (it does not
matter which two of the three available trigger inputs
are used for Occurrence Mode).
Signal Input wire colors are as follows:
Trigger Signal 1 = Black
Signal Common 1 = White w/Black Stripe
Trigger Signal 2 = Brown
Signal Common 2 = White w/Brown Stripe
Trigger Signal 3 = Red
Signal Common 3 = White w/Red Stripe
3.3 Auto Formula Select Wiring
Input specifications are the same as trigger inputs.
The Auto Formula Select signal must be programmable to the second on the washing machine control
system. Program the washer to send this signal at the
start of the wash load (prior to any chemical supply
signals) for a duration of 2 seconds times the desired
formula number (i.e. for formula 2 program for 2s *
F2 = 4 seconds signal time).
Auto Formula Select input wire colors are as follows:
Auto Formula Select Signal = Orange
Auto Formula Select Signal Common = White w/
Orange
