DFS TROUBLESHOOTING GUIDE
Refer to pages 19 and 20 to view figures
Symptom: The unit has been turned on but the High Voltage Power Supply Indicator Light (HVPS1) is OFF
Probable cause #1: Short in High Energy Grid (foreign debris, loose wires, loose electricalconnection)
Confirmation:
Step 1: Disconnect power to unit
Step 2: Remove a Filter Access Door by first removing the Safety Switch Screw located on the bottom of
the Filter Access Door towards the Inlet Side of the housing then the flange nuts. (fig-1)
Step 3: Disconnect the High Voltage Lead from the High Energy Grid. (fig-3)
Step 4: Safely secure the male end of the High Voltage Lead between the Prefilter and the High Energy
Grid as to ensure that the High Voltage Lead cannot contact the blower wheel.
Step 5: The following steps should be done with extreme care and the person(s) performing this
test should ensure that unauthorized personnel cannot come in contact with dangerous
moving parts and high voltages.
Defeat Safety Interlock: Replace the Safety Switch Screw (without the Filter Access Door) and
tighten (by hand) until the Safety Switch Screw is tightened.
Step 6: Return power to the unit and put the unit into run mode. Observe the status of the High Voltage
Power Supply Indicator Light (HVPS1). If the light is now functioning the problem is in the High
Energy Grid.
Disconnect power to the unit, remove the Safety Switch Screw and follow these steps:
(A) Loosen the top and bottom Scissor Locking Mechanism located near the motor plate on the
Inlet Side of the filter unit. Make sure the Scissor Locking Mechanism is fully opened.(fig-2)
(B) Ensure the High Voltage Lead is disconnected from the High Energy Grid. (fig-3)
(C) Using a firm pull, remove the V-Bank Main Filter and High Energy Grid Assembly out of the
filter access opening.
(D) Separate the High Energy Grid from the V-Bank Main Filter by removing the two screws in
the center of the V-Bank Main Filter. (fig-5)
(E) Inspect the High Energy Grid and its wires, they should be free from debris and evenly
tensioned. Loose wires can cause arcing or cause the protection circuit to trip.
(F) Inspect the “V” sections of the V-Bank Main Filter and ensure that it is free of metal debris,
excess dirt or hair etc…
(G) Secure the V-Bank Main Filter to the High Energy Grid by using the two center screws in the
center of the V-Bank Main Filter.
(H) Stand the V-Bank Main Filter and High Energy Grid Assembly up (as it sits in the unit) and
inspect the gasket on the seal side of the Assembly. Replace the gasket if it is damaged
(I) Slide the V-Bank Main Filter and High Energy Grid Assemblyback into theunit.
(J) Tighten the top and bottom Scissor Locking Mechanism.
(K) RepeatStep5fromaboveandplacetheunitin runmodetoconfirm theproblemhas beenresolved.
Conclusion: If the High Voltage Power Supply Indicator Light stays off this indicates a faulty Voltage
Multiplier. Disconnect power from the unit and replace the Voltage Multiplier. Repeat Step 5
from above and place the unit in run mode to confirm the problem has been resolved.

Probable Cause #2: Faulty Voltage Multiplier / Faulty High Voltage Power Supply (HVPS)
Confirmation:
Step 1: Disconnect power to unit
Step 2: Open the Electrical Box attached to the unit with (2) gray flexible electrical conduits
Step 3: Locate the Voltage Multiplier in the bottom right hand corner of the Electrical Box. The Voltage
Multiplier is a gray, rectangular device with red and black wires at one end and a single red wire
at the opposite end. (fig-9)
Step 4: Disconnect the red wire of the Voltage Multiplier from the “J3” terminal of the High
Voltage Power Supply (HVPS). Stay clear of this terminal while testing and Do Not attempt
to
re-connect the terminal with power applied to the unit.
Step 5: Re-connect power to the unit
Step 6: Place the unit in “run” mode and observe the status of the High Voltage Power Supply
Indicator Light (HVPS1)
Conclusion: If the High Voltage Power Supply Indicator Light stays off with no Voltage Multiplier
attached there is a fault in the High Voltage Power Supply. Disconnect power from the unit
and replace the High Voltage Power Supply.
If the High Voltage Power Supply
indicator light is on with no Voltage Multiplier attached the fault
is either in the High Energy Grid or in the Voltage Multiplier.
