Operation Procedures
Knowledge of the proper operation of the MX3-500 is required to ensure
user safety and efficient performance of the extractor.
SET UP AND OPERATION
1. Electrical Cords:
Two 25’ power cords are supplied with the Nautilus MX3-500. The amperage required by each cord requires
that the two cords be plugged into separate circuits:
• Cord #1 (Left side) Powers vacuum #1, vacuum #2 and cooling fan. Cord #1 must be connected to a
20amp circuit.
• Cord #2 (Right side) Powers solution pump, the optional 1750W heater and optional waste pump if so
equipped. When the optional heater is used Cord #2 must be connected to a 20amp circuit. Units
without a heater or with the heater turned OFF cord #2 of the MX3-500H can be connected to a 15amp
circuit.
20amp circuits are usually found in kitchens and bathrooms. An overloaded circuit will not always trip
the circuit breaker immediately, but it may not provide sufficient voltage for proper operation and the breaker
may trip eventually.
Plug the two power cords into two outlets from different circuits. If the Dual Circuit Indicator green light
fails to light, you may be on the same circuit and may need to select a different plug for one of the cords. If
the Dual Circuit Indicator green light comes on, you are plugged into two different circuits. Proceed with
your set-up procedure.
(Dual Circuit Indicator Light may take up to 30 seconds to recognize the two circuits and turn ON.)
If a circuit breaker trips or the pump circuit breaker trips during operation, reset the breakers and move the
cord to another outlet as needed.
When operating the MX3-500 using the OPTIONAL 1750W
heater DO NOT turn the heater on until after the pump has been primed and solution
hose and tool connected – Steps #3, #4 & #5.
