INSTALLING, CLEANING AND TESTING
Water Connections(s)
No water connection is needed. The water will be poured directly
into the water cavity reservoir.
Make sure that the incoming water connection is made with a 3/4”
N.H. COLD water supply hose. Rigid pipe is not required. The
water pressure should be between 30 and 60 PSIG. Higher
pressures will require the use of a pressure regulator. Make sure
that all connections are tight with no leaks-no matter how small.
NOTICE: The quality of the water is a factor in the proper
performance of the steamer. The water supply should have a
minimum value of 30-40 parts per million of total dissolved solid
(TDS).
Drain Connection
The Vortex100 Connectionless Steamer should be manually
drained to the bottom containment pan supplied by the factory.
If the unit is connected to a drain, do not connect more
than
two units to one drain line or pressure from one unit will effect
the second unit.
Steam Vent Assembly Instructions
Remove steam diverter assembly from literature bag which can
be found inside unit. Slide loose end as shown over unit steam
outlet, tighten worm gear clamp with flat head screw driver.
Be sure steam outlet is pointing in the upward position.
(Shown below)
Stacking Units Instructions
Remove drain containment pan from the bottom of unit(s).
Unscrew to remove adjustable legs from base of Vortex unit(s).
Unfasten nuts and bolts on stand platform(s). Place Vortex
unit(s) on stand platform. Align the (4) leg holes with the holes
in the platform. Secure Vortex units(s) to stand platform(s) using
bolts an
d washers provided with stand, see drawing below.
For double stack units only:
By loosening the left screw and removing the right screw provided,
mount steam exhaust bracket assembly to the back panel of the
top Vortex100 unit as shown in detail “B” of Figure 1 on the next
page. Attach the steam exhaust hose from the bottom Vortex
unit’s steam outlet tube to the top Vortex unit’s steam exhaust
bracket assembly using hose clamps provided as shown in figure
2 on the next page. (Note: Steam exhaust hose may need to be
cut to fit.)

Drain Line Installation
Unitswithauto-fILLoRManuaLwithDRainKIt
The drain line should not be less than:
1-1/2” - for single units
2” (5E) - for double stacked units
There must be a 2” air gap to the (non-pressurized) building
drain. Make sure that the drain is sloped AWAY and DOWN
from the steamer and that there are no obstruction in the line.
Failure to observe these requirements may cause a water trap
in the drain line and produce enough back pressure to prevent
proper cavity draining-resulting in condensate water leaking
from the door. Drain line must not NOT be made of plastic pipe.
It must be able to withstand boiling water.

WARNING
Keep water and cleaning solutions
out of controls and electrical
components. Never hose or steam
clean any part of the unit.
Even when the unit has been
shut off, don’t put hands or tools
into the cooking chamber until
the fan has stopped turning.
Don’t operate the unit unless the
removable partition has been put
back in its proper location.
Do not use any acidic cleanser
products to clean the unit.
IMPORTANT
Do not use any metal material (such as metal sponges)
or metal implements (such as a spoon, scraper or
wire brush) that might scratch any stainless steel surface.
Scratches make the surface hard to clean and provide
places for bacteria to grow. Do not use steel wool,
which may leave particles imbedded in the surface which
could eventually cause corrosion and pitting.

4.2 VRC Checkout
1. Apply power to the VRC. On the back of the front-panel control
board, flip the left DIPswitch up to start the diagnostics.
2. The red 7-segment display on the front panel should have some
of its segments lit. If they are not then check the fuse and circuit
breaker on the control transformer. Then check that all har-
nesses are in place and that the connectors are properly seated.
Check for 24 VAC at the secondary of the control transformer.
3. Turn the knob so that the red display shows A1 (Analog 1 – RTD
temperature). The green display should show the approximate
temperature of the RTD probe in the cavity. If it shows a very
small number or zero then the harness connecting the RTD to
the control board is probably shorted to ground. If the number
is very large – around 250 or more – it means the RTD or its
harness is open or disconnected.
4. Turn the knob to A4 (Analog 4 – Line voltage). The green display
should show the approximate line voltage.
5. Turn the knob to b (button). Push each button. The light near the
button should light. Also, check that pushing the top two buttons
makes the bottom two lights go out.
6. Turn the knob to P (Product code). The green display should
show 001 for a standard VRC or 003 for an auto-fill VRC. If any
other number is displayed the ribbon cable connecting the
front-panel control board to the relay board is incorrect.
7. Turn the knob to S (Sensors). As each sensor is activated the
associated green bar will light. If it doesn’t then that sensor or
harness connection is faulty. Refer to this diagram:
8. Short the Hi probe to ground. The Hi probe bar should light after
a few seconds. Remove the ground wire.
9. Short the Lo probe to ground. The Lo probe bar should light after
a few seconds. Remove the ground wire.
10. Close and open the door. The Door Open bar should go out
when the door is closed. Use a magnet to check the door switch
on the other side. The bar should go out when the magnet is
near the door sensor.
11. Push the ON end of the rocker switch. The Power bar should
light. Push the OFF end of the switch. The bar should go out.
12. Remove J5 connector from the relay board, the overtemp
thermistor bar should light. Reconnect the J5 connector on
the relay board, the overtemp thermistor light should go out.
13. Turn the knob to O1 (Output 1 - Shutdown). Push the ON (upper)
end of the rocker switch. The large contactor closest to the back
panel should pull in. Push the MANUAL button. The contactor
should drop out.
14. If the VRC is equipped with auto-fill turn the knob to O2 (Output
2 – Fill valve). Push the MANUAL button a few times. The fill
valve should open whenever the button is pushed.
15. Turn the knob to O6 (Output 6 - Heater). Push the ON end of
the rocker switch. Short the Lo probe. Push the MANUAL
button a few times. The large contactor closest to the front
panel should pull in whenever the button is pushed. Check
for proper line current on all three phases when the button
is pushed. Note: For the heater to turn on the power must be
on, the Lo probe must be shorted, and the overtemp thermo -
stat must be operating properly.
16. Turn the knob to O7 (Output 7 – Fan). Push the MANUAL button.
The fan should run.
17. Turn the knob to O8 (Output 8 – Beeper). Push the MANUAL but
-
ton. The beeper should beep.
18. Turn the knob to 88. All lights and all display segments should
light.
19. On the back of the front-panel control board, flip the left DIP-
switch down to start normal VRC operation. The red heartbeat
LED on the back of the control board should blink about once a
second.
20. Perform the normal VRC checkout (add water, check steam
production, etc.).
