__________________________________________________________________________________ SECTION 4 WARNINGS AND CAUTIONS Warning: Connect water inlet according to the specifications for the Granuflo Dissolution Unit The water used must meet ANSI/AAMI standards for water used in hemodialysis (currently RD62). The correct ionic concentration and bacterial quality can generally be achieved in the dialysate only with treated water. Be sure that all specifications are satisfied. The water source must be monitored periodically to detect fluctuations in water composition and quality that could have an adverse effect on the patient, hemodialysis machine or Granuflo Dissolution Unit. Particular attention must be taken for chemicals such as aluminum, chlorine, and chloramines, as these chemicals can cause complications in dialysis patients. The chemical quality of the treated water used for dialysis should be analyzed a least once a year to ensure it meets the requirements of ANSI/AAMI RD62. Warning: The operator should always check conductivity and approximate pH of the dialysate with an independent device prior to initiating treatment and whenever concentrates are changed during operation. Warning: Failure to install, operate, and maintain this equipment according to the manufacturer’s instructions may cause patient death or injury. Warning: This Granuflo Dissolution Unit may be susceptible to electromagnetic interference (EMI). Devices emitting electromagnetic radiation such as analog portable phones, radio equipment (walkie-talkies, etc.), radio transmitters, and like equipment, should not be used in the vicinity of this equipment. The operator should monitor the function of the machine and remove unnecessary equipment from the treatment area should these events occur. Warning: The electrical source must be single phase, three-conductor type provided with a ground fault interrupter at 120 volts, 60 Hz. The proper polarity and ground integrity must be initially checked and maintained. Failure to do so may result in electrical shock or burn to the operator. Warning: Shock hazard. Do not remove covers. Refer servicing to qualified personnel. Replace fuses only with the same type and rating. Warning: Following disinfection, two (2) complete rinse cycles must be done and tested to ensure the absence of residual disinfectants. Warning: Granuflo acid concentrate contains acetic acid. The use of a dust mask, rubber gloves and safety goggles are recommended when handling. If contact with eyes, rinse immediately for 15 minutes. If contact with skin, flush with plenty of soap and water. If ingested, drink several glasses of milk and use antacids to reduce acidity. Warning: Use the supplied hydrometer to measure the specific gracility of a sample of the mixed Granuflo concentrates. Refer to Table 2 for the nominal specific gravity for Granuflo formulations. Caution: The Granuflo Dissolution Unit is computer controlled. Extreme care should be exercised in its operation. When power is connected to the Granuflo Dissolution Unit I version 2, a failure of the computer could start any of the operations at any time.

When the power cord is not long enough to be serviceable, a licensed electrician must install a new three wire grounded receptacle in accordance with the National Electrical Code. Do not use a three to two prong "cheater" (adapter) with this device. Should the power cord or plug become cracked, frayed or otherwise damaged, it should be replaced immediately. Always remove the power cord from the power source before attempting to service this device. Never unplug the unit by pulling on the power cord. 8.1 VISUAL INSPECTION Visually inspect the Fresenius Dissolution Unit prior to each use. The operator should look for any defects which may inhibit the safe or proper operation of the Unit. Items such as damaged hydraulic hoses or fittings, damaged electrical cables or connections, loose, missing or damaged hardware or process contamination should be corrected prior to the use of the Fresenius Dissolution Unit. 8.2 CLEANING Clean the exterior surface of the Fresenius Dissolution Unit thoroughly after each batch of concentrate is mixed. If necessary, a mild detergent solution may be used to clean the exterior surface. Care should be taken not to contaminate the system interior. All spills should be wiped off immediately. Spillage at the control panel should be avoided in order to minimize the possibility of electrical malfunction. CAUTION: Do not use chemical cleaning agents that may damage the material used in the Dissolution Unit. Agents which contain BENZENE, TOLUENE, XYLENE, ACETONE or any other AROMATIC or KETONE solvents must be avoided. 8.3 DISSOLUTION TANK DISINFECTION 1. Disinfect as required to maintain water quality. 2. Remove the Filter Housing and discard the Filter Element. Replace the Filter Housing, but do not insert a replacement Filter at this time. 3. Follow the RINSE CYCLE procedures in Section 6. When the water reaches the 25-Gallon level during the second rinse, add 1.9 liters (0.5 gallons) of bleach (sodium hydrochlorite 5.25% to 7%) to the rinse water in the Tank and allow it to recirculate for the duration of the RINSE CYCLE. 4. At the completion of the last rinse step (to which the bleach has been added), initiate two (2) complete RINSE CYCLES by following the steps in Section 6. 5. When completed, test for residual bleach in the system at the Transfer Drain Outlet Nozzle, and inside the Tank. To test for residual bleach quantities, follow the protocols of your facilities. If residual bleach levels are higher than ANSI/AAMI Standard limit of <0.5 ppm (RD62), initiate another complete RINSE CYCLE. After the RINSE CYCLE is complete you must check again for residual bleach. Continue this rinse and test procedure until bleach residuals are within ANSI/AAMI Standard limit of <0.5 ppm (RD62).
