Read and understand the user manual before operating this unit.
Do not operate above 100°F (38°C) maximum ambient temperature, near open flames, sparks,
or smoking materials. Keep cover closed when unattended.
To provide continued protection against risk of electrical shock, fire, and explosion, connect to
properly grounded supply or outlets only.
Risk of explosion. This equipment has internal arcing and sparking parts, which shall not be
exposed to flammable vapors. This equipment shall not be located in a recessed floor are or
below grade.
Only cleaning fluids with a flash point at or above 104°F (40°C) shall be used. Refer to user
manual for a list of solvents which have been evaluated for use.
Do NOT contaminate cleaning solution with fluids below 104°F (40°C) flash point including
gasoline, alcohol, or other flammable liquids. Even small amounts will create a hazardous
condition.
Ensure fusible link and closing device are in proper working order. Fusible link melts at
165°F(74°C) causing lid to close. When open the lid must lean forward so it will close
automatically when link melts. Do NOT tamper with or remove the fusible safety link. If the safety
link breaks or is lost, do NOT use the unit. Replace the safety link immediately.
Hazardous voltage present. Disconnect power before repairing or cleaning. Unit must be properly
grounded to prevent electric shock, fire, and explosion hazard. Connect only to three prong
outlets. Should cord become cracked, frayed, or damaged in any way, it should be repaired
immediately by a qualified electrician. Never use an extension cord. Since operator safety at all
times is a priority, we strongly recommend that, whether or not required by local code, this
equipment be connected only into a power supply equipped with a “Ground Fault Interrupter”
(GFI). All electrical connections should conform to national/local codes and be made by qualified
personnel.
Do not leave objects in the tank or let hose attachments exit the tank which prevent lid from
closing completely in the event of fire.
