• 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 gas-
spring 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
TM
cleaning solution to
prevent the machine from shutting down due to low
liquid levels.
POWER SUPPLY, WIRING AND
GROUNDING
• Failure to permanently ground the unit and controls
before connecting to electrical power can cause
shock, burns or death.
• 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
instructions.
• If cleaning solution is splashed on clothing, remove
promptly and thoroughly wash any body areas which
have been in contact with solution. DO NOT permit
saturated clothing to remain in contact with skin.
Consult cleaning solution’s MSDS instructions.
• Clean up fluid spills immediately. Super Biotene
TM
can
create a slippery surface. Also, the microbes
metabolize organic materials and could damage floor
coverings or painted surfaces.
• Graymills strongly recommends that federal, state and
local authorities be consulted before proceeding with
discarding and handling of used materials. Graymills
Corporation accepts no responsibility for user’s
failure to comply with regulations.
• For best results, Graymills’ recommends using only
Super Biotene
TM
550 (concentrate) or Super Biotene
TM
660 (pre-blended).
