Water supply conditions
• Potable water, softened water, or pure water can be used.
• The water hardness should not exceed 400 ppm. The recommended water hardness is
150 ppm
1
or lower.
• The water supply quantity at water supply/circulation nozzle on the reprocessing basin should
be 6 liters per minute (1.6 gallon per minute) or more when the water faucet is fully open. The
recommended water supply quantity is 18 liters per minute (4.8 gallons per minute) or more.
The process time is extended if the water supply amount is lower than 18 liters per
minute.
• The water supply pressure should be between 0.1 and 0.5 MPa (Include water hammer).
• The water temperature should be between 5qC (41qF) and 28qC (82qF).
• The water should not contain rust, dirt, or other foreign matter.
Drain conditions
• The top of the drain hose should be no higher than 60 cm. A floor drain is recommended.
• The diameter of the drain piping of the facility should be 36 mm (1.4 in) or more (a 100 mm
(3.9 in) pipe is desirable).
• The drain capacity of the floor drain should be 50 liters per minute (13.3 gallons per minute)
or more (this capacity should be maintained until all of the fluids in the reprocessing basin are
drained).
• The floor drain should be connected to a waste fluid treatment or pooling facility.
• The specification of drain above is for one unit of the equipment. When using more than one
unit in your facility, a larger size of floor drain will be required.
Power supply conditions
• Power supply capacity should be enough for the equipment rating (120 V AC, 5.5 A, 60 Hz,
voltage fluctuations within ±10%, frequency fluctuations within ±1 Hz).
• The power outlet should be a hospital-grade, wall mains power outlet (3-conductor,
grounded).
*1 The recommended value is in reference to AAMI TIR34: 2014 “Water for
the reprocessing of medical devices”.
