  • Page 16: Operational Overview

    OPERATIONAL OVERVIEW The MediQA is available as a single pass or dual pass reverse osmosis (RO) unit to be used for purification of potable water for renal dialysis applications. Potable water enters the MediQA through an inlet solenoid valve filling the feed water tank. A high pressure pump delivers water from the feed water tank through the 1st stage RO module set (may comprise of one or more modules), with each module containing a high performance membrane.
  • Page 17 The MediQA can be set to “POWER ON STANDBY” for occasions when there are long periods (typically days during shut down periods) without use. In standby mode the MediQA is factory set to perform 10 minutes of operation in every 2 hours, these values are adjustable. This enables water to be circulated through the MediQA and distribution loop, in order to maintain water quality.

  • Page 18: Sequence Of Operations

    4.2 Sequence of Operations Concentrate Throttle Valve Product to Loop Valve Recirculation Throttle Valve Loop Return Valve Concentrate to Drain Valve 4.2.1 Introduction There are two modes of operation, Hi Recovery Mode and Standard Recovery Mode. Hi Recovery Mode is the default and can be toggled to Standard Recovery Mode on the RO Supply screen (see Section 6.4.1).

  • Page 19: Hi Recovery Mode

    4.2.2 Hi Recovery Mode This mode of operation is designed to limit water usage while still meeting water quality standards. Hi Recovery Mode uses up to 40% less water than Standard Recovery Mode. The mode is comprised of Flush, Rinse, and Supply. FLUSH Before the MediQA provides water to the loop for dialysis use, the system goes through a flush.

  • Page 20: Standard Recovery Mode

    Reject to Tank: Concentrate and permeate water will recirculate to the feed water break tank until the permeate quality reaches the HI RECOVERY QUALITY HIGH LIMIT or BREAK TANK TEMPERATURE HIGH LIMIT set-points. When these set-points are reached the reject to drain period will begin and the RO will dump the reject water to drain.

  • Page 21: Cleaning Procedure

    4.2.4 Cleaning Procedure CHEMICAL CLEAN The MediQA is equipped with the ability to perform a chemical cleaning of itself once chemicals have been added in the tank. This consists of 4 main steps, circulation, tank drain, high pressure rinse, and low pressure rinse. Valve positions are shown in the following figures. Recirculation: During the recirculation phase of the chemical clean process, the valves redirect all of the water back into the MediQA tank.

  • Page 22: Disinfection Procedure

    4.2.5 Disinfection Procedure HEAT DISINFECTION The MediQA is capable of a heat disinfection of its plumbing and membranes. During the heat disinfection process the RO circulates water within itself at 185˚F for 30 minutes (adjustable). The valves on the unit are programmed to act in similar fashion to the valves during a chemical disinfection of the unit.

  • Page 23: Heatsan Control

    4.2.6 Heatsan Control The Heatsan is capable of turning the MediQA on when requesting water and locking the unit out when hot water is in the loop. HEATSAN FILL The MediQA can be called on to provide water to the Heatsan. Be sure that MINT cable is connected between MediQA and Heatsan for fill procedure to function.

  • Page 24: Pump Operation

    LOOP HEATSAN (COOLDOWN AFTER HEAT DISENFECTION OF THE LOOP) When the Heatsan unit performs a disinfection of the loop, the unit must be cooled down to allow cold water from the RO to be supplied to the Dialysis machines. By connecting the MediQA to the Heatsan via the MINT cable, the Heatsan unit can call for a fill from the MediQA when it needs to be cooled down.

  • Page 25: Installation

    INSTALLATION 5.1 Environment The unit should be installed in a clean and dry indoor, non-hazardous, ventilated environment (see Section 3.3). 5.2 Unpacking Two people are required for this operation. Manual handling requirements should be observed. The MediQA is shipped on a wooden pallet. Before removing it, ensure the MediQA is as close to the final location as possible on a smooth level surface.

  • Page 26: Commissioning

    5.4 Commissioning ONLY BY CERTIFIED AMERIWATER REPRESENTATIVES. This Reverse Osmosis System (RO) contains a preservative solution to prevent WARNING: microbiological growth and freezing. Discard all product water for at least two hours of operation before placing the RO in service.

  • Page 27: Heatsan Water Loss Lockout

    The MediQA utilizes fail safe connections for the Alarm Panel. The alarm output is normally closed, so that when there is an alarm, this opens. AmeriWater supplies an alarm panel that can be set to either normally open or normally closed contacts. As shipped, the alarm panel will look for a closure to indicate an alarm condition.

  • Page 28: Initial Startup

    The check valve must be oriented to allow flow into the loop return port of the RO, but no flow from the RO to the loop. Back Pressure Regulator Portions of the kit are shipped loose to allow flexibility based on space constraints at installation. To adjust the back pressure on the loop, loosen the lock nut on the bottom of the back pressure regulator.
  • Page 29 Installer shall verify polarity for pump(s) rotation before proceeding with RO startup. The rotational direction can be found on the name plate on the pump(s). Navigate to the CALIBRATION MENU > OVERRIDES and toggle “RO1 PUMP” on then off, view the rotation of the green light on the face of the pump.
  • Page 30 Once water is clear close the tank drain valve and install the tank lid. Navigate SETTINGS MENU > RO SUPPLY and increase the Auto Flush time to 15 minutes and Auto Rinse time to 5 minutes. Level 3 User Login will be required for this step. Also, click the ENTER button under MEDIQA OPERATION MODE.
  • Page 31 (CALIBRATION MENU > RO PARAMETERS). Verify permeate flow on screen matches the return flow on the product recovery kit flowmeter. If the flow values do not match, then call AmeriWater for the Gain and Offset values for the permeate flowmeter on the unit.
  • Page 32 Navigate SETTINGS MENU > RO SUPPLY > MEDIQA OPERATION MODE ENTER and hold ENABLE for 2 seconds to return to Hi Recovery Mode upon completion of the 2 hours. Hi Recovery Quality is default to a low limit of 8 µS and a high limit of 12 µS during RO Supply. Break Tank Temperature is default to a low limit of 80 °F and a high limit of 90°F.
  • Page 33 To complete set up, navigate SETTINGS MENU > RO SUPPLY > SUPPLY TIME SCHEDULE ENTER to get to the screen shown below. Enter the times necessary for the RO to supply water each day, using 24:00 clock. If there are days no operation is necessary, then enter a start and end time of 00:00. When in TIMER mode the machine will operate on this schedule.
