Irrigator Connections; Drawing Water From The Tank - Interacoustics Aqua Stim Instructions For Use Manual

2.6 Irrigator connections

Do not plug in the handle electrical connector when the irrigator is powered on. If the handle
does not operate, power down the irrigator and check the handle electrical cable is plugged in
securely into the back of the irrigator.
The Aqua Stim is shipped from Interacoustics without any water in the tank. Please fill the external tank with
3½ L of good quality water (preferably distilled or demineralized) that is not considered "hard water" due to
high mineral content. Do not fill above the 3½ L mark. Connect the color coded Inlet (white) / Outlet (grey)
tubes between irrigator and the external water tank. Push the tubes into the connectors until they "snap" in.
To remove the tubes, push on the small ring next to the tube using two finger tips while pulling gently on the
tube. Connect the red and blue tubes from the handle to the back of the irrigator. Verify that the arrow [→] on
the red tube's water filter is pointing away from the irrigator. The electrical connector from the handle plugs
into the back of the irrigator. Note that the electrical connector is keyed for orientation. Rotate the connector
between the fingers while gently pressing in on the connector until it seats and makes connection. A ground
lug is provided on the rear panel for electrical testing by BMETs. Plug in the 240 VAC power cable into the
AC power cord connector. If the Aqua Stim is used in conjunction with video nystagmography (VNG)
software then connect the USB cable to the VNG computer, otherwise leave the USB cable disconnected.

2.7 Drawing water from the tank

The external water tank should be placed on the same table as the irrigator. For the first operation, turn on
the irrigator using the power switch on the back of the irrigator at the power entry. Once the irrigator has
power and the front panel display shows Select Cool/Warm, press the "Cool" button on the front panel. The
irrigator will draw water from the external water tank and fill the internal heater tank. There will be a change
in pitch of the irrigation pump as it self-primes. Some water will flow from the irrigator back into the external
tank from the overflow tube. Read the front panel display to confirm the current water temperature is
displayed and that the irrigator is heating to the preset 30ºC temperature.
The Aqua Stim uses two filters to catch any contaminants in the water. A pickup filter is attached to the end
of the inlet tube in the external tank. An inline filter is placed within the handle's red tube. Inspect these filters
periodically to make sure they are not blocked.
