Note the cartridge catalog number, lot code, and expiration date on each cartridge. If the cartridges have been installed longer than one year, replace the cartridges first. If you have an organic removal cartridge installed in position four (far right), try switching this cartridge with the cartridge in position three. If the purity rises to acceptable levels, the organic cartridge is most likely at fault. 2. Measure the flow rate from the remote dispenser, which should be approximately 1.5 liters per minute. If the flow is significantly lower, open the front door and locate the pump in the unit. Place your hand on the pump or listen for vibration (the pump should be on/vibrating whenever the purity is displayed on the screen). If the pump is not running, locate a screwdriver, grab it by the blade, and tap repeatedly on the pump. The pump may start running again. If the pump does not continue to run, order a new pump, part number PU896X3. If the pump is running and the flow is still low, check the following: a. Ensure feed water is of adequate pressure (Gravity feed – 100 psi acceptable, 30-50 psi preferred) b. Ensure no other filters are clogged (0.2 micron final filter or Ultrafilter) c. Ensure there are no kinks or clogs in the tubing or other component (most notably the pressure regulator) 3. Purchase a NIST calibration module, part number E896X5. After you receive the module, first perform a calibration per the user’s manual. Then, leaving the module attached, press “start” on the display, and note the purity value. With the module plugged in, the display should read 15.0 Mohm-cm. If it does read 15.0 (+/- 0.3 Mohm), your boards are reading the purity properly. If it does not read 15.0 when plugged into J2 of the calibration board, try plugging the module into P2 of the meter board (slightly larger board, also mounted on the side door of the Nanopure). If the reading does change to 15.0 when plugged into P2, the calibration board is bad. If it does not change to 15.0 when plugged into P2, the meter board is most likely bad. 4. Examine the check valve by removing the tubing from its end. If the valve allows water to leak out the end, attempt to free any clogged debris or replace the valve.

1. Open the front door of the Nanopure and examine the cartridges. Note the cartridge catalog number, lot code, and expiration date on each cartridge. If the cartridges have

been installed longer than one year, replace the cartridges first. If you have an organic

removal cartridge installed in position four (far right), try switching this cartridge with

the cartridge in position three. If the purity rises to acceptable levels, the organic

cartridge is most likely at fault.

2. Measure the flow rate from the remote dispenser, which should be approximately 1.5 liters per minute. If the flow is significantly lower, open the front door and locate the

pump in the unit. Place your hand on the pump or listen for vibration (the pump

should be on/vibrating whenever the purity is displayed on the screen). If the pump is

not running, locate a screwdriver, grab it by the blade, and tap repeatedly on the

pump. The pump may start running again. If the pump does not continue to run, order

a new pump, part number PU896X3. If the pump is running and the flow is still low,

check the following:

a. Ensure feed water is of adequate pressure (Gravity feed 100 psi acceptable, 30-50 psi preferred)

b. Ensure no other filters are clogged (0.2 micron final filter or Ultrafilter)

c. Ensure there are no kinks or clogs in the tubing or other component (most notably the pressure regulator)

3. Purchase a NIST calibration module, part number E896X5. After you receive the module, first perform a calibration per the users manual. Then, leaving the module attached, press start on the display, and note the purity value. With the module plugged in, the display should read 15.0 Mohm-cm. If it does read 15.0 (+/- 0.3

Mohm), your boards are reading the purity properly. If it does not read 15.0 when

plugged into J2 of the calibration board, try plugging the module into P2 of the meter

board (slightly larger board, also mounted on the side door of the Nanopure). If the

reading does change to 15.0 when plugged into P2, the calibration board is bad. If it

does not change to 15.0 when plugged into P2, the meter board is most likely bad.
