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.

TROUBLESHOOTING
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 har­nesses 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:
Heater Overtemp
Hi Float
Lo Float
Door Open
Overtemp
Power
Sensor LED Bars
8. Lift the hi float and hold it up. The Hi Float bar should light after a few seconds. Release the float.
9. Lift the lo float and hold it up. The Lo Float bar should light after a few seconds. Release the float.
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. On the left side of the VRC, under the heater plate at the front, disconnect one of the terminals on the thermostat closest to the front panel. The Overtemp bar (the one in the middle of the display) should light. If the Heater Overtemp bar (the top one) lights then the wiring to the two thermostats is probably crossed. Reconnect the terminal. The Overtemp (middle) bar should go out.
13. Disconnect one of the terminals on the thermostat farthest from the front panel. The Heater Overtemp (top) bar should light.
Reconnect the terminal. The Heater Overtemp (top) bar should go out.
14. 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.
15. 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.
16. Turn the knob to O6 (Output 6 - Heater). Push the ON end of the rocker switch. Lift the lower float all the way up and hold it up. 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 lower float must be up, and the overtemp ther­mostat must be operating properly.
17. Turn the knob to O7 (Output 7 – Fan). Push the MANUAL button. The fan should run.
18. Turn the knob to O8 (Output 8 – Beeper). Push the MANUAL but­ton. The beeper should beep.
19. Turn the knob to 88. All lights and all display segments should light.
20. On the back of the front-panel control board, flip the left DIP­switch down to start normal VRC operation. The red heartbeat LED on the back of the control board should blink about once a second.
21. Perform the normal VRC checkout (add water, check steam production, etc.).
