INSTALLATION
Mount the unit (using suitable hardware) with the
provided bracket in the accessory kit. Try to keep the
unit within three feet from the final rinse line to avoid
long tubing runs.
CAUTION: Do not mount the unit in the direct path
of steam. This can short circuit and permanently
damage the unit. Mounting the unit on the side, on
the back, or on the vents of the dishwasher may
cause thermal overload and damage or hinder the
performance of the unit.
Check all applicable plumbing and electrical codes
before proceeding with the installation. This will help to
ensure that the system is installed in safe and suitable
manner. A wiring schematic of the dishwasher should
be used as reference for making electrical connections
— this is typically provided by the dishwasher
manufacturer if one cannot be located on the machine
itself.
Rinse Plumbing
(1) Install the provided 1/4" tube x 1/8" NPT injection
fitting into the side or bottom of the dishwasher
rinse line between the rinse solenoid valves and the
rinse jets. If necessary, drill a 11/32" hole and tap to
1/8" NPT. Use of a saddle clamp may be desired on
copper rinse line for better support.
(2) Cut a suitable length of 1/4" OD poly tubing and
connect between the discharge (right) side of the
rinse pump’s squeeze tube and the injection fitting.
Cut 2” of the supplied T-50EH tubing (7018061)
and zip tie the tubing to the pump suction and
discharge fitting. (See Diamgram A below). Use
the T-50EH tubing to connect poly tube to the pump
fitting.
(3) Cut a suitable length of 1/4" OD poly tubing and
connect between the suction (left) side of the rinse
pump’s squeeze tube and the pickup tube provided.
Be sure to draw tubing through the end of the
pickup tube.
(4) Hand-tighten the compression nuts on both the
rinse fitting and pickup tube. Plastic ties can be
used to cinch around the connections where the
poly tubing is inserted into the pump’s squeeze
tube.
Liquid Detergent Plumbing
(1) Install the provided bulkhead fitting through a wall
of the wash tank (above water level). If an existing
mounting hole cannot be located, use of a 7/8" hole
saw or punch may be desired.
(2) Cut a suitable length of 1/4" OD poly tubing and
connect between the discharge (right) side of the
detergent pump’s squeeze tube and the bulkhead
fitting.
(3) Cut a suitable length of 1/4" OD poly tubing and
connect between the suction (left) side of the
detergent pump’s squeeze tube and the pickup
tube provided. Be sure to draw tubing through the
end of the pickup tube.
(4) Hand-tighten the compression nuts on both the
bulkhead fitting and pickup tube. Plastic ties can be
used to cinch around the connections where the
poly tubing is inserted into the pump’s squeeze
tube.
Dry Detergent Plumbing
(1) A powder or solid type feeder (not provided) should
be used for dispensing dry detergent products.
Follow the instructions included with the detergent
feeder for installation, and recommended water
temperature/pressure.
(2) Cut a suitable length of 1/4" OD copper tubing (not
provided) and connect between the input side of the
water solenoid and the water source. Maximum
recommended water temperature is 140°F (60°C).
(3) Cut a suitable length of 1/4" OD copper tubing (not
provided) and connect between the output of water
solenoid to a powder or solid detergent feeder.
(4) Carefully tighten the compression nuts on the water
solenoid — over tightening may cause solenoid to
leak. Tighten connections to the water source and
detergent feeder as needed.
INSTALLATION
Diagram A

0901177 Rev: A (10/15) Page 5 of 12
ELECTRICAL
Turn off all power before wiring the control. Check
with a voltmeter to ensure power is off.
Main Power Connection
One step-down transformer is provided with the UMP
control. Connect the high voltage side, through a switch
or circuit breaker in close proximity to the equipment
and marked UMP, to any 115/208/230 VAC power
source that is “on” when the dishmachine is “on” (i.e.
mains switch on dishmachine).
NOTE: The transformer provides power to both the
detergent and rinse circuits. The UMP will only operate
detergent or rinse when electrically signaled.
To wire main power connection:
(1) Check the voltage of the main power source and
make sure that it matches one of the three available
input voltages (115/208/230 VAC) of the
transformer inside the Ultra Micro-Pro.
(2) Remove all power from the dishwasher.
(3) Connect leads from the main power source to the
appropriate wires on the transformer.
* CAUTION: The UMP unit has high voltage connected
to the transformer. Always disconnect main power when
servicing the unit.
Remote Alarm
A remote 3 - 28 VDC alarm may be wired to the “alarm”
terminals on the circuit board. See wiring diagram on
page 10.
Pressure Switch Kit
For applications that do not have a dedicated rinse
signal from the dishwasher, the pressure switch can be
used to create a rinse signal using the transformer in the
unit (see wiring diagram for further details).
(1) Remove power from the dishmachine. Ensure that
power is removed from the dispenser.
(2) Locate the rinse injection fitting presently installed
on the dishmachine (if applicable). Near the
injection point, drill a hole for the pressure switch.
Drill the hole using a 11/32" bit and tap to 1/8" NPT.
(3) Wrap the threads of the pressure switch with 3 - 4
turns of plumbing tape, then install the pressure
switch into the drilled/tapped hole.
(4) Wire the pressure switch per the appropriate wiring
diagram on page 10.
Detergent Power Signal
A detergent power signal is required to activate the
detergent probe sensing or probeless initial charge. The
detergent signal can be jumpered from main power for
applications where the main power is controlled by the
on/off state of the dishmachine.
(1) Check the dishwasher for a power source that is
active during the washcycle only (example: the
magnetic contactor that controls the washpump
motor) and verify voltage. The Ultra Micro-Pro
circuit board will accept a detergent power signal of
14 - 240 VAC.
(2) Remove all power from the dishwasher.
(3) Connect leads from the detergent signal power
source to the detergent signal terminals on the
circuit board. Detergent signal must be the same
voltage as Rinse signal.
Rinse Power Signal
In addition to running the rinse pump, the rinse power
signal also triggers the detergent “recharge” injection if
probeless mode is selected
(1) Check the dishwasher for a power source that is
active during the rinse cycle only (example: the
rinse solenoid or rinse cycle light) and verify
voltage. The Ultra Micro-Pro circuit board will
accept a signal of 14 - 240 VAC.
(2) Remove all power from the dishwasher.
(3) Connect leads from rinse signal source to the rinse
signal terminals on the circuit board. Rinse signal
must be the same voltage as Detergent signal.
Conductive Probe Installation (if used)
(1) Install the probe in the wash tank below the water
level. It should be away from incoming water
supplies, near the recirculating pump intake, and 3
to 4 inches from corners, heating elements, or the
bottom of the tank. If an existing mounting hole
cannot be located, use of a 7/8" hole saw or punch
may be desired.
(2) Connect leads from the terminals on the probe to
the terminals marked “PROBE” on the circuit board.
(3) For best results, use 18 AWG multi-stranded
copper wire for the probe connection. Avoid running
the wire near high voltage AC lines.

OPERATION
Detergent — Probe Mode
The system has the option of using a conductive. With
the detergent signal “on”, the probe senses detergent
concentration. When concentration drops below the
setpoint, the control automatically turns on detergent
feed. As the detergent feeds, the control senses the rate
at which the detergent concentration is approaching the
setpoint. The control then begins to pulse feeds to
prevent over-use of chemical. The pulse feed rate will
depend on how fast the setpoint is being approached.
The detergent alarm will sound if the setpoint is not
reached within the alarm delay time period. The alarm
can be temporarily silenced. A “feed limit” feature allows
you to set the unit to automatically shut off the detergent
feed when the alarm has been activated.
Detergent — Probeless Mode
Controls detergent concentration without a probe, based
on timed detergent feed modes. Initial charge time feeds
detergent to bring the dishmachine to working
concentration when initially filled with water. The initial
charge can be activated by a detergent signal, or by the
rinse signal (of 30 seconds duration, or longer) when
using door mode. The initial charge counter will
increment for each activation.
Recharge time feeds detergent to maintain detergent
concentration as rinse water dilutes the dishmachine.
The recharge is triggered after a specified number of
racks passes through the machine.
Rinse Pump
The rinse pump will operate whenever the rinse signal is
energized. The rinse delay feature will postpone the
activation of the rinse pump until the delay time has
expired. The rinse limit shuts down the rinse pump after
the signal has been present for a selected time. Rinse
delay and rinse limit are functional with door machines
only.
