C. Common Issues
1. Canister power switch does not click when pedal is depressed.
-This switch should NOT “click”� In a typical switch, such as the one on the mid-size canister, the click you hear is the movement of the metal
contact inside the switch� This contact remains either in contact - completing the circuit, or dis-connected - breaking the circuit� There is
no rocker or latch to hold the contacts in place in the full-size canister so you will not hear a “click”� The circuit is momentarily completed by
depressing the switch, sending a signal to the PC board� That signal is interpreted as an instruction to turn the canister “On”� Depressing
the switch a second time instructs the PC board to turn the canister “Off”�
2. What to check rst when canister will not power up.
-Dislodged electrical connectors are the usual cause of the canister not powering up� Make sure that all of the electrical connectors are
rmly and securely engaged. It only takes one dis-connection to interrupt the proper operation of the canister cleaner.
3. Interpreting blinking LED light on the main PC board.
-This light indicates whether the main PC board is maintaining proper communication with the handle PC board� The light should be
blinking at an approximate rate of 2 seconds on, 2 seconds off� If it is blinking at a faster rate of 0�5 seconds on, 0�5 seconds off, there is
an interruption in the communication between the two PC boards� If the light does not blink at all, there is a problem with the power being
supplied to the main PC board�
4. Canister will not run without the hose connected.
-The hose must be connected to complete the circuit before the canister will run� This is due to the variable control being mounted in the
handle assembly�
5. Canister cuts on and off at the customers house but runs in the store.
-The power at the home may vary due to the current load on the circuit� Wiring in the house may not be heavy enough to carry the load of
the canister plus the other items connected�
6. Canister cuts on and off when plugged into a power strip, but runs when plugged into the wall.
-The power strip breaker is not large enough to handle the 12 AMP canister for extended period of time�
