each wash & rinse cycle. Before accessing the bottom section of the dishwasher, make sure
that the power is turned off at the
source (breaker panel).
The bottom panel can only be
removed with a flat tool like a screw-
driver. Insert the screw-driver in the
gap between the front panel and the
side panel. Pry open towards you.
Do this on both sides.
The red & blue hoses connected to the pumps must be routed out of the
bottom of the dishwasher. The red tube is for detergent and the blue tube is for
rinse additive. The containers can be either to the right or left of the
dishwasher. Perforating the stainless panel is not recommended.
The two chemical pumps are factory adjusted to accommodate most installations.
There is a mark on the pump indicating this setting.
It is recommended that only qualified personnel alter these settings.
UNDER NO CIRCUMSTANCES should the detergent pump be
turned off.

VISUAL CHEMICAL DELIVERY VERIFICATION
The peristaltic chemical pumps are located in the base of the dishwasher. They
feature a transparent cylinder (1) to visually see if fluid is passing through the
pumps. The pumps are automatically energized during the “initial fill” (when
turning on the dishwasher) and “rinse cycle” (after the wash cycle). During this
time, the flow indicator (2) will move between the “Min Flow” position and the
“Max Flow” position (3) in the cylinder. It is normal for the pumps to cycle on and
off.
If the flow indicator (2) does not move during the fill or rinse, no fluid is
circulating through the pump. It is recommended not to use the dishwasher until
this condition is resolved.
TROUBLESHOOTING
1. Ensure that there is sufficient chemical in the container and that the tube is not kinked.
The filter on the end of the tube must reach to the bottom of the container. If the filter or
tube is blocked, remove and soak in warm water to dislodge the obstruction.
2. There may be air in the pump. To “Prime” the pumps (remove the air), turn off and drain
the dishwasher. Replace the stand pipe, close the door and turn on the dishwasher. The
pumps will be activated as the machine fills. The Flow Indicators (2) should start to move
by the time the machine has filled. If not, repeat the drain and fill.
3. The Squeeze Tube (flexible tube inside the pump) is worn or perforated. This part is a
normal wear and tear item that must be replaced periodically (when pump performance
diminishes). Call for Service.
4. The pump does not operate - the roller in the middle of the pump does not turn during the
fill or rinse. Call for Service.
For any other request on set-up and installation, please contact us toll free at 1 888 275 4538

IMPORTANT: Remember to always use caution and protective gear whenever you are
manipulating chemicals. They can burn the skin. Follow the manufacturer’s instructions carefully.

BASIC STEPS TO START
Begin with an empty dishwasher. The wash tank should be empty.
Make sure the filter screens and the overflow pipe are in place.
Close the door.
Push the square green button. The dishwasher will take about two minutes
to fill and 20 minutes to heat the water. The booster (rinse) will heat up first
and then the wash tank will heat up.
When the dishwasher is ready, the ready light will come on. This indicates
that the dishwasher has reached optimum temperature.
You can now start washing.
Fill the basket. Only one basket can be used at a time.
Slide it in to the dishwasher.
Close the door and press the round black button. The dishwasher will start
washing for a few minutes. When the wash pump stops, the rinse is about to
start. Verify that the Rinse Pressure Gauge (P.6) is showing 20-30 PSI and
that the Chemical Flow Indicators (P.19) are moving. The rinse continues for
approximately 20 seconds.
When the cycle light (near the start button) goes off, open the door and
remove the tray to let air dry.
If you are ready for another wash, slide a basket in the dishwasher, close the
door & press the Cycle Start Button. If not, just close the door to retain the
heat in the dishwasher and conserve energy.
You should drain the dishwasher at least once a day or when the water is soiled.
The dishwasher should be turned off, drained, cleaned and left empty at night.
To drain the dishwasher, follow these simple steps;
Turn OFF the power.
Pull out the overflow tube (CAUTION: water may be hot)
Press the white drain button (if so equipped) until all the water is gone. Be
careful not to let any debris go down the drain as it may block the pump.
21
OPERATION
Before operating the machine, ensure that the electrical power, water supply and drain connections
have been made as per the installation instructions.
Ensure that the overflow pipe is correctly set in its place (inside the wash tank). The overflow pipe
should never be forced into its position. For the first use of the day, the wash tank should not have
any water.
Familiarize yourself with the gauges, buttons and indicator lights on the
control panel.
Check chemical levels. The containers should have sufficient quantities
of Detergent (for wash) and Rinse Additive (drying agent).
Press the Square Green Power Button (1).The Power Indicator Light
will illuminate (as well as the Digital Temperature Gauges , if so equipped).
If the wash tank is empty, the machine will start to fill. Always keep the door
closed during this time. When the machine has filled to its required water
level, the elements will then raise the rinse and wash
water temperatures automatically.
It will take approximately 15-20
minutes in order to obtain the
optimum temperatures (185°F in the
booster and 160°F in the wash tank).
The Ready Indicator Light (5) will
illuminate to indicate that the machine
is ready for its first load.
Fill the basket with dishware and
trays then push the basket into the
machine.

It is more economical to wash
when the basket is fully loaded. It is
also important not to overload the
basket. Water should always be
able to spray freely around the
dishware and trays.
Overflow
Press the round black Cycle Start
Button (6) to start the wash cycle.
On the model 767, set the selector to 2, 4 or 6 minute wash.
Closing the hood on Models F-22, 747 & 767 will automatically start the cycle. The Cycle Indicator
Light (7) will illuminate. The cycle starts and consists of a wash (up to 6 minutes), a brief pause and
then a rinse (from 18 to 25 seconds). Another basket can be filled while the first one is being
washed. The Cycle Indicator Light (7) will extinguish to signal the end of the cycle. It is important to
remove the basket from the machine while they are hot to let the dishes air dry. They will not dry if
left in the machine.
22
IMPORTANT NOTES:
-The
models
F-22,
747
and
767
differ from the under-counter units in the way
to initiate the wash cycle. Once the unit has filled up with water and the
temperatures have reached their maximums, slide the basket in and close the door.
Closing the door will start the wash cycle. At the end of the cycle, after the cycle
light has switched off, open the door and remove the basket. The cycle light will
come on at that point for a few seconds to reset the timer for the next wash.
- JET-TECH high temperature warewashers do not dump water and fill after every
cycle. The wash water is refreshed during every cycle by the hot
rinse water. Only excess water is expelled from the machine via the overflow
pipe. If the wash water becomes soiled, it is recommended turn off and drain the
dishwasher, clean
all debris from the filters and wash tank and turn on the dishwasher to
fill with fresh water
- Some models are equipped with an automatic drain pump (White button on the
front control panel) that will evacuate excess water. Please see the section
on: DRAIN PUMP OPERATION.
- During the rinse cycle, verify that Rinse Pressure is 30 PSI and that
the Chemical Flow Indicators are moving.
- IMPORTANT: If the dishwasher will not be used for two (2) or more hours, it should
be drained and turned off. The dishwasher should never be left in the “ON” position
and unattended.

DRAIN PUMP OPERATION
Models 727, 737, F-16DP and F-18DP are factory built with drain pumps. A square white button
on the control panel beside the green power button also evidences this feature. All other models
have a gravity drain.
Drain pump equipped models will pump the waste water to a maximum height of 36” (0.9 meter). A
1” ID flexible hose of sufficient length is provided to facilitate maintenance and servicing of the
machine. It is important not to reduce the size of this hose. A 1” check valve* may be required. There
should be sufficient hose length to permit the machine to be pulled out for service. Drainage time
should not exceed 1 minute.
The drain pump activates automatically during a rinse cycle and functions when the water fill valve
is open: during the fill and rinse cycles. This allows the removal of excess water entering the unit.
To manually drain the wash tank, you must:
1. -Turn off the machine (square green button on control panel).
2. -Open the door, remove the basket, and remove the overflow pipe (also known as stand pipe).
3. -Press and hold the white button on the control panel, which will activate the drain pump.
Release the button when the water has been discharged.
The most common causes of drain pump failure are:
-Debris was flushed down the drain and blocked the impeller in the pump. Removing the impeller
cover and clearing the obstruction generally restores normal pump function.
-The drain hose, at the back of the unit, is restricted.
IMPORTANT! Pump failure caused by debris blockage is NOT covered by the warranty.
