SAFETY WARNINGS

You will find various types of safety information on the following pages and on the labels attached to Graymills equipment. The following
Safety Statements explain their meaning:

This is the safety alert symbol. It is used to alert you to potential personal injury
hazards. Obey all safety messages that follow this symbol to avoid personal injury or

READ BEFORE OPERATING

death.

DANGER indicates a hazardous situation which, if not avoided, will result in death or
serious injury.

WARNING indicates a hazardous situation which, if not avoided, could result in death
or serious injury.

CAUTION, used with the safety alert symbol, indicates a hazardous situation which, if
not avoided, could result in minor or moderate injury.

CAUTION, without the safety alert symbol, is used to address practices not related to
personal injury.

• Use only Super BioteneTM cleaning fluids. Do NOT

use solvents, gasoline, etc., as they will create an
extremely hazardous situation.

• Do NOT contaminate cleaning fluid with any

flammable or combustible material such as gasoline,
alcohol, mineral spirits, etc. Drain parts to be cleaned
of any flammable material or combustible material
before cleaning. Even small quantities can create a
dangerous fire hazard.

• Never work with equipment you feel may be unsafe.

Contact your supervisor immediately if you feel a
piece of equipment is in unsafe condition.

• Cleaning solutions may be irritating to skin and eyes.

Always wear gloves, apron and safety glasses when
using. If splashed in eyes, flush thoroughly with

• The unit has been factory set to maintain an optimum

temperature for the microbes. Do NOT attempt to
change thermostat setting.

• This is a heated system. Always use caution when

first putting hand under liquid stream to prevent injury
from heated solution. If the liquid feels uncomfortably
hot, discontinue use, unplug machine and call
Graymills Customer Service.

• Failure to keep proper liquid level will result in

burning out the pump and heater coil, creating a
potential fire hazard. To help prevent this, this unit is
equipped with a low liquid level device which will shut
off the pump and heater. If solution stops circulating
and the red “RESET” light becomes illuminated,
immediately turn off and unplug unit. For instructions
on filling the reservoir, please see “INSTALLATION
AND OPERATION” steps 6 through 9.

BIO436R Only

• After extended use, the gas-spring used to assist in

opening and closing the lid may lose its ability to keep
the lid open. At the first sign of this, replace the gas­spring immediately.

• Automatic Safety Cover. Since certain soils may be

combustible, e.g., oils, greases, this unit is equipped
with a fusible safety link cover mechanism designed
to support the open cover at a slightly forward angle.
In the event of a fire, the fusible link will melt at 165ºF
permitting the cover to slam shut, limiting oxygen
supply to the fire.

• Do not leave the unit unattended with parts in the tank

which would prevent the cover from closing
completely in the event of a fire. Keep cover closed
when unit is not in use. If the fusible link breaks, do
not operate the unit until a replacement link is
installed.

• DO NOT leave the unit disconnected without power for

extended periods of time (overnight or weekends).
This will cause the microbes to go dormant. This will
adversely affect the bioremediation process. If
microbes do not reactivate after operating
temperature has been reached, a new BIO-POUCH
should be added.

• If unit is to be unused, but not unplugged or turned

off, for extended periods (overnight and weekends), it
may be necessary to top-off tank to the 30-gallon mark
with pre-blended Super Biotene
prevent the machine from shutting down due to low
liquid levels.

• 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.

• Unit must be properly grounded to prevent electric

shock hazard. Connect only to three-prong 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 Spare Parts List)

• The full-load amperage draw for this machine is 12

amps.

USE OF INDUSTRIAL CLEANING
SOLUTIONS

• Always wear the recommended safety apparel and

glasses.

• Adequate ventilation should be provided when

operating this unit.

• When making an initial batch of cleaning solution or

when adding compound, follow cleaning solution’s
directions exactly.

• Industrial cleaning solutions may be irritating to some

individuals. Be certain to consult the MSDS for the
cleaning solution you are using before filling or using
parts washer.

• If splashed in the eyes, follow cleaning solution MSDS
