Thank you for purchasing the Mark V+.
Please read the instruction manual carefully before use.
The Mark V+ continues the legacy of the original Mark V. The Mark V+ offers the most powerful
suction and quietest operation on the market.
With the Mark V+ you can suction wax from hearing aids and earmolds and blow air to remove
dust and debris from devices and surfaces.
The large powerful drying chamber provides a powerful vacuum for completely drying out
instruments quickly.

Assembly Instructions
Chamber Release Valve
Circuit Breaker 4A
Insert one tube into the ports marked suction and pressure on the front panel of the Mark V+.
Push tube in firmly. Pull on tube gently to see it holds. If not, push in again.
The suction and pressure filter/wand assembly is attached to the opposite end of the tube by
pushing the tip firmly into the tube. For best results, push tip all the way into tube. Needles
attach to the luer lock tip of the filter/wand assembly.
To connect the suction and pressure wand holder, look for the two holes on the side of the unit.
Affix the holder by inserting the two screws (included) into those holes. Please look at diagram
of “Font & Top View” for orientation.
Before using, be sure the Chamber Release Valve on the back of the unit is all the way
closed (clockwise). Suction will not engage if valve is not closed.

Operating Instructions
4
To use the pressure wand, push the POWER button in. Then push the Wand button until it is “out”
to activate wand. Pressure and suction are operational at the same time, but when the wands are
working, the Drying Chamber is off. Use the pressure wand to clean out vents and volume
controls.
The Mark V+ is equipped with a circuit breaker to protect the motor from circuit overload and
power surges. If the circuit breaker trips, wait 60 seconds then press the circuit breaker in to
return to normal operation.
The filter for the Mark V+ is assembled in the hand wand. When the wand appears dirty, simply
replace it by pulling it off the tube and replacing it with a new one.
Drying Chamber
To use the drying chamber, push the POWER button in. Then push the Drying Chamber button
“in” to activate chamber. Gently push the drying chamber lid down until the vacuum holds it firm.
The motor will turn off automatically after 15 minutes of continuous use. To release the lid at
anytime, turn off the POWER button and twist the Chamber Release Valve, located on the back
of the pump, counter clockwise until you hear a release of air. Once lid is released, return
Chamber Release Valve to closed position by fully turning valve clockwise.
Suction Wand
To use the suction wand, push the POWER button in. Then push the Wand button until it is “out”
to activate wand. Suction and pressure are operational at the same time, but when the wands are
working, the Drying Chamber is off. Carefully move the suction needle into the area to be cleaned,
such as the microphone, receiver and sound ports. Do NOT use the Mark V+ to clean ears.
NOTE: In stubborn cases, it may help to place a few drops of hydrogen peroxide in the
microphone and receiver with a syringe. Allow the hydrogen peroxide to penetrate, then suction
again. Do NOT use alcohol in the microphone or receiver.

Needles
Attach appropriately sized needle (included) to the luer lock tip of the filter/wand assembly.
Needles can be used for both suction and pressure wands. It is recommended that the larger
diameter needles are used for the pressure wand and the smaller diameter needles are used for
the suction wand.
Operating Instructions Continued
Tubing
To remove tubing from suction and pressure ports, push blue ring “in” while pulling tubing out. To
insert tubing, push tubing firmly into the port with blue ring. Once inserted, pull on tube gently to
ensure it is secure.

Notes
Keep the needle from bending. Use the reamer (included) to clean out clogged suction
needles.
When suctioning, great care should be exercised to not insert the needle too deeply into the
microphone or receiver.
The motor will shut off automatically after 15 minutes of continuous use.
This equipment is not suitable for the removal of corrosive and particulate dust-containing
gases and explosive gases.
This equipment is only used for the maintenance of hearing aids and earmolds. It
should NOT be used to clean ears.
