dispenser. It can accept a 100-115VAC nominal to 200-249VAC nominal (+/- 10% fluctuation) main
power input at 50 or 60 Hz. Rinse and Detergent control signals are universal “machine interface”
types that are capable of accepting any voltage from 24 to 240 VAC nominal (+/- 10% fluctuation) or
24 VDC (+/- 20% fluctuation). SPRITE can control either capsule or liquid detergents.
1
Cost Savings
A special Rinse Saver Feature prevents rinse additive waste during fills of the washer. Digital electronics ensure accurate detergent control and minimize overuse.
Intelligence
The SPRITE includes a rack counter as a “standard” feature. A unique “De-Lime” mode allows for
safe washer cleaning without detergent waste.
Choice of Options
A full range of programmable options are included, such as rinse delay, variable alarm volume, and
manual prime for both rinse and detergent.
Easy Service/Repair
The SPRITE features convenient front access for all servicing. No internal access to the cabinet is
required for installation and routine maintenance. In the unlikely event that repairs are required, spare
parts are available in modular form for fast and convenient service.

Probe Mounting
(Probe Operation Only)
Bracket
The probe senses the detergent concentration. Correct probe placement is
critical for accurate detergent concentration control. Always use the new
probe provided with the dispenser.
When choosing a mounting location, make sure that the probe will be completely immersed in the wash tank solution, in an area that has a good flow
of solution, and close to the product entry point.
Figure 2-3 Probe Mounting
Many dish machines will have knockouts provided for probe installation and/or will have existing probes.
Previously punched probe holes may be suitable, but always confirm that the probe will be immersed in the
wash tank solution before installing. The following steps describe probe installation.
If a probe hole is present, skip to Step 2.
1. Drill a 3/8" hole in the center of the probe location. Use a Greenlee (or similar) 7/8" hole punch to
cut the final hole.
2. Remove the probe retaining nut.
3. From inside the dish machine tank wall, insert probe (with rubber gasket) into hole.
4. From outside the dish machine tank wall, install second rubber gasket, plastic washer and probe
retaining nut. Tighten finger-tight only.

(tube from pump)
with a 1/8" NPT threaded hole. If an optional pressure switch will
be used, thread the injection fitting into one side of the pressure
switch water source fitting pipe tee. If the machine already has a
tapped hole to accommodate the fitting, skip to Step 3.
Figure 2-4 Rinse Injection Fitting
Choose a location for the rinse injection fitting that is at least 6" downstream from the solenoid valve and
vacuum breaker. On continuous rack, flight, or conveyor machines, be sure this location is downstream
from any rinse makeup water.
1. Drill a 7/32" hole in the rinse plumbing injection location.
2. Tap the hole drilled in Step 1 with a 1/8" NPT tap.
3. Install the injection fitting. Use thread sealant to ensure a leak-free assembly.
Detergent Bulkhead Fitting
(Liquid Detergent Only)
Caution
,
Follow the instructions provided with your solid, powder, or slurry feed
system for solenoid equipped units instead of using the following section.
Correct placement of the detergent bulkhead fitting is critical for accurate detergent concentration control
(in probe mode only). When choosing a mounting locating, make sure that the detergent bulkhead fitting is:
• Above the water line in the tank.
• Close to the probe location (when possible).
• Discharging detergent directly into the wash tank and not on top of any shelf areas or other
obstacles that could prevent detergent from falling directly into the wash tank.
Previously punched holes may be suitable, but always confirm that the fitting is correctly placed.
If a hole is present, skip to Step 2.
1. Drill a 3/8" hole in the center of the detergent inlet
location. Use a Greenlee (or similar) 7/8" hole
punch to cut the final hole.

The detergent signal input is an optically isolated signal input that draws no more than 20 mA. It is a universal voltage input that accepts any voltage between 24 and 240 VAC nominal (+/- 10% fluctuation), or
24 VDC nominal (+/- 20% fluctuation).
Detergent Signal Wiring – Probe Mode
Typical wiring locations are dispenser detergent power source or the wash motor contacts in the dish
machine control panel. This power source is on when the dishwasher is running the wash pump.
• Connect yellow (DC +) and white/yellow (DC -) colored wires to detergent power source.

Detergent Signal Wiring – Probeless Mode
~
On conveyor type dishwashers, the detergent signal must occur only once per dish machine fill/
drain occurrence–beginning when the dish machine fills. Typical wiring locations are an “on light” or
an electrical tank heat circuit between the tank heater switch and the thermostat. Each time this power
source comes on, and stays on for 10 seconds, the dispenser will feed the detergent initial charge
amount (with probeless and automatic initial charge modes set).
On door-type dishwashers, connect this signal input to the dispenser detergent power source or the
wash motor contacts in the dish machine control panel. This power source is on when the dishwasher
is running the wash pump.
• Connect yellow (DC +) and white/yellow (DC -) colored wires to initial charge power source.

The rinse signal input is an optically isolated signal input that draws no more than 20 mA. It is a
universal voltage input that accepts any voltage between 24 and 240 VAC nominal (+/- 10%
fluctuation), or 24 VDC nominal (+/- 20% fluctuation). Typical wiring locations are dispenser rinse
power source or the rinse solenoid valve circuit in the dish machine control panel. This power source
is live whenever the dishwasher is rinsing. When no suitable rinse signal connection is available, an
optional pressure switch may be used with a constant power source instead.
• Connect violet (DC +) and white/violet (DC -) colored wires to rinse power source (or constant
power for pressure switch installations).
Probeless Mode
Note
#
Certain dishwasher designs require that the rinse aid be dispensed upon the
detergent signal, rather than the rinse signal. In this case, you must still connect the
rinse signal input to either the fill solenoid or the rinse solenoid circuit of the
dishwasher to enable the automatic initial charge function in probeless mode.

Automatic Initial Charge
In a door-type dishwasher, the Automatic Initial Charge occurs each time the dispenser receives a
rinse signal that was not preceded by a detergent signal within 90 seconds prior (i.e. on an initial fill).
When this condition occurs, the dispenser detects an Automatic Initial Charge, disables the rinse feed,
and feeds detergent for the time that is set in Menu 41. (See “Detergent I nitial Charge (Menu 41)” on
page 6-9 for more information.) Normal rinse signal activations (within 90 seconds after a detergent
signal) will not generate an initial charge.
A five minute lockout timer begins at the start of initial charge; this prevents an additional initial
charge from occurring if multiple rinse signals are detected during fill.
In a
conveyor-type dishwasher

off for 90 seconds (or Detergent Initial Charge time, if longer), and the detergent feeds for the time that
is set in Menu 41(see
“Detergent Initial Cha rge (Menu 41)” on page 6-9
It is important to note that this will happen each time a detergent signal occurs, so the source of this
signal must remain on for the entire time the tank is full, or not occur more than one time per machine

Troubleshooting
Overview
This chapter describes the troubleshooting displays and methods for the Sprite, including:
• Alarms and Indicators
• Preliminary Checks
• No Display
• No Detergent Feed (Probe and Probeless Modes)

Rinse Pump Jammed
Preliminary Checks
If unit is dead, no display, go directly to Dead Unit (No Display). Otherwise, check the indicators and
alarms for information about the dispenser.
Dead Unit (No Display)
• Confirm main power connection voltage with a volt meter.
• Check fuse if optional fuse kit is installed.
• Substitute transformer followed by the printed circuit board to determine fault
P/N 20-06270-00 Rev. N 7-1
No Detergent Feed
• For either Probe or Probeless Modes, confirm that detergent type (screen 23) is set correctly.
Probe Mode
• Temporarily disconnect probe wire (with detergent signal on) to force detergent feed.
- If detergent feeds, check for probe scaling and check detergent setpoint setting.
- If detergent does not feed, replace pump motor (or solenoid coil), then printed circuit board.
Probeless Mode
• Confirm that unit is in a detergent feed condition as determined by rinse/initial charge signal inputs
and initial charge/dose adjustments.
• If detergent does not feed, substitute pump motor (or solenoid coil), followed by the printed circuit
board to determine fault.
Excess Detergent Consumption
Probe Mode
• Check probe for scaling.
• Measure wash solution via titration kit or other means. If detergent is at proper concentration,
check the dish machine for clogged drains, excessive fresh water feedback, etc.
Probeless Mode
• Confirm that initial charge is dispensed only one time per initial fill. If you experience multiple
initial charge feeds (Automatic/Conveyor mode only), review initial charge wiring connection.
• All other modes, adjust initial charge and dose adjustments accordingly.
No Rinse Feed
The unit is programmed to lock out the rinse feed under certain conditions. Check for the following conditions:
• Probeless/Door/Automatic Initial Charge modes—Rinse is locked out after Initial Charge begins
until the following rack (rinse signal) occurs.
• Probe Mode—Detergent signal did not occur within 90 seconds prior to rinse signal (Rinse Saver
feature).
If the problem is not in one of the above conditions and rinse does not feed, substitute pump motor, followed by the printed circuit board, to determine fault.

Maintenance
8
Routine maintenance on the Sprite unit includes:
• Keeping the probe clean (probe mode operation only)
• Keeping pump tubes fresh
• Keeping the unit clean
Repairs to the unit involves modular component replacement. This minimizes spare parts inventory
requirements and speeds up the service process in the field.
Every Maintenance Visit
• Titrate the wash tank solution to verify that unit is holding accurate concentration.
• Clean probe, if required.
• Clean the unit cabinet with a damp cloth.
• Check the pump tube's condition and replace, if needed.
Pump Tube Replacement
Replace pump tubes at regular maintenance intervals, well before the tube fails and ruptures. If the tube
does rupture, clean all product from the pump with a damp cloth.
• Loosen the pump front captive screw and remove the pump front.
• Remove the old tube with barbed connectors.
• Install the new tube with barbed connectors oriented with flat sides facing towards the front.
• Insert new tube from left side of pump, with pump spinner oriented in an 11/1 o'clock position.
• Turn the spinner clockwise, using a screwdriver, as you press the pump tube in place.
