Model BIO922 Operation Manual 795-93073_0715 3
• Unit must be properly grounded to prevent electric shock
hazard. Connect only to threeprong outlet. Should cord
become cracked, frayed or damaged in any way, it should
be repaired/replaced immediately by a qualified electrician.
Never use an extension cord. (See PARTS LIST,
page 5)
• Install ground and wiring according to local and national
electrical code requirements.
• Install a fused disconnect switch on all power legs near the
unit.
• Disconnect and lockout electrical supply before installing or
servicing unit.
• The fullload amperage draw for this machine is 12 amps.
MACHINE INSTALLATION AND OPERATION
• Unit is shipped fully assembled. Optional caster cart and light will
require some assembly; see separate Instruction Sheets if purchased.
• Place unit on a smooth, level surface in a well ventilated area.
• Read all warnings posted on machine.
• Inspect electrical control box, cord and plug for wear or damage.
Do not use machine or add fluid if any wear or damage is
noticed until impaired components are repaired or replaced.
• Install filter cartridge:
1. Unscrew filter cartridge bowl.
2. Remove clear plastic packaging from new filter cartridge and remove
BIO-POUCH from hollow center of cartridge.
3. Install new filter cartridge in the cartridge bowl.
4. Re-attach filter cartridge bowl to filter body.
Be sure electrical cord is unplugged, and cleaning solution
and heater coil are cool before adding cleaning solution or
performing any maintenance.
FILLING UNIT
If filling reservoir with hot water, be sure temperature does not
exceed 110°F. Higher temperatures can cause burns to skin and
will damage pump seals. Unit’s thermostat has been factory set
to prevent cleaning solution temperature from exceeding 110°F.
Do not attempt to change thermostat setting.
• Remove stopper from drain.
• Add about 30 gallons of Biotene mixed with water, filling to the base of
the sink.
• Put center stopper back into drain opening.
OPERATING UNIT
• Plug power cord into properly grounded 115V, 15 amp circuit. Air pump
will begin operation immediately upon power being applied to the
machine.
• Press
TEST
button on GFCI on rear of control box (on right side of unit)
to ensure switch is operating properly. Press
RESET
button on GFCI to
prepare unit for operation.
• Toggle
RESET
switch located under the electrical box. If the unit has an
adequate level of cleaning solution in the tank, the green “
READY
” light
will illuminate.
• If cleaning solution is not up to the set temperature of 110°F and there is
sufficient fluid in the tank, the heater will begin operating. If the solution
does not warm, unplug machine and call factory.
• Place stainless steel shelf on mounting ridges inside tank.
• To operate the fluid pump, toggle ”
PUMP”
switch on front of electrical
box to the ON position.
• For fluid flow through the flexible hose turn the directional valve pointing
to hose. For fluid through the flow-thru brush turn the directional valve
pointing to brush. The center position will allow flow through both.
• Unit is equipped with a low liquid level device which will shut off the
pump and heater. If solution stops circulating and the green light goes
out, immediately turn off and unplug unit. Allow unit to cool and add
more cleaning fluid.
• Failure to keep proper liquid level will result in burning out
the pump and heater coil, creating a potential fire hazard.
• When not in use, turn pump off and place plastic stopper in the center
drain to minimize liquid loss due to evaporation. Do NOT disconnect
the unit from electricity even if not to be used for extended periods of
time. The internal air pump and heater are necessary for maintaining
bioremediation. Turning off the unit will cause the microbes to go
dormant and will adversely affect the bioremediation process. If
temperature should drop and the microbes do not reactivate after
operating temperature has been reached, a new BIO-POUCH should
be added.
USING SINK AS SOAK TANK
• To use unit as a soak tank, position the plastic stopper in the center drain.
Do not remove the flexible rubber strainer. It is best if parts to be cleaned
are placed in sink before filling.
• Turn on pump to begin fluid flow. Leave pump running and fluid flowing
through either the flow-thru brush or flexible hose. The fluid will drain
back into the base when the liquid level reaches the drainage holes in
the sink. This continuous flow refreshes the soaking fluid with filtered and
heated solution and supplies gentle agitation.
Position hose so fluid does not splash out of sink or toward
operator.
Make sure that drainage holes in sink are not obstructed.
• Drainage holes will allow cleaning fluid to circulate back to base of unit
to be reheated and filtered. If they become obstructed, turn off pump
and clear obstruction before continuing.
• To return all fluid to base, remove stopper.
• When sink is fully emptied, clean rubber strainer of any debris. Return to
center drain before continuing to use unit.
