Warning

Equipment Safety Guidelines

The following warnings and cautions are specific to the EV800 Elevating Table. Read them carefully - some of them are not obvious to typical equipment use.

Turn off electrical power to the table at the power source before servicing the table. Also, make sure that the power source is locked out and tagged “Table Being Serviced” before servicing the table; you could get seriously shocked or burned if you do not.

Do not place any objects within the vertical motion area above or below table. Objects in such areas can present crush hazards for the patient or operator and can also damage the table. See shaded areas in figure below.

The table is equipped with a collision avoidance switch for downward motion. This switch is designed to protect the table top, not the operator or patient from a collision. The downward motion of the table will stop if the table encounters 100 lbs (44kgs) of upward force.

i-6 Equipment Safety Guidelines

Caution

Warning

Caution

Use extreme care when moving the base off the pallet and not to damage the foot pedals. Do not pry on the pedals or let the pedals rest on the edge of the pallet when moving the base.

14 Lift the base off the pallet and place the base in its final resting

position.

You must use four 1/2’-13 x 3” (M12 X 75mm) bolts and appropriate anchors and washers to mount table base to floor. Use of any size smaller may cause the table base to break free from the floor under extreme load and leverage conditions. This condition could cause severe injury to the patient and/or user.

It is up to the installer and the customer to determine the best method for mounting the base to the floor. Before mounting the base, consult with the building’s maintenance supervisor about drilling holes in the floor. Make sure that there are no hazards under the floor such as pipes, conduits, or structural cables that can be damaged by drilling holes in the floor.

Do not mount the table base to the floor until the tubestand or overhead tube crane that accompanies it has been mounted and aligned correctly; you may have to reposition the table if you do.

15 Mount the base to floor using holes through bottom of the base. There

are several sets of holes that allow some adjustability in positioning the base. Choose the set of holes that best suits your needs, and then make sure that base is level after mounting. If necessary, use shims from accessory kit to aid leveling.

4.2 Cleaning External Surfaces

Tools Required:

• Cleaning wipes

•Non-abrasive, hospital-grade cleaner

Use cleaning wipes and non-abrasive, hospital-grade cleaner to clean external surfaces of table and base.

Turn off all electrical power to the table and all its peripheral equipment (generator, tubestand, etc.) at the power sources before servicing the table. Also, make sure that the power sources are locked out and tagged “Equipment Being Serviced” before servicing the table. Some components inside the table have power sources other than that of the table, which is why all peripheral equipment must be turned off; you could get seriously injured if you not.

This equipment is NOT classified as anaesthetic-proof and may ignite inflammable anesthetics. Flammable agents used for skin cleaning or disinfecting may also produce an explosion hazard.

• Ensure the power has been disconnected and that the emergency switches have been activated before starting any cleaning operation.

• Ensure no liquid gets into the unit.

• Do not immerse the equipment, including any components or accessories, in liquid.

• Do not autoclave the equipment, including any component or accessories.

• Do not use water. Water can short-circuit the electrical installation and cause corrosion to mechanical parts.

• Do not use acid or abrasive products.

• Use only a dry cloth to clean chrome-plated parts.

4-2 4.2 Cleaning External Surfaces

Page 73

EV800 Elevating Table Installation, Operation, & Service Manual

• Only the surface areas of unit parts, including accessories and connection cables, should be disinfected using a gaseous disinfectant. For safety reasons, do not spray disinfectants.

• Clean painted parts with a cloth and use products appropriate for cleaning plastic materials. After cleaning, wipe the surfaces with a clean, dry cloth.

• Do not spray cleaning or disinfection solution directly on the equipment. To disinfect, moisten a cloth with a 70% Isopropyl alcohol solution or equivalent and wipe the surface of the equipment.

• When disinfecting the examination room ensure the unit is covered with plastic sheets.
