INSTALLATION
Milli-Q Synthesis/Synthesis A10 24
Chapter 4 INSTALLATION
4-1 CONNECTING TO A SUPPLY OF FEEDWATER
FEEDWATER IS FROM A RESERVOIR
Make sure the Reservoir is full of purified water (i.e. RO or Elix water). Make sure the Milli-Q is located either
beside or lower than the Reservoir. It is not advisable to locate the Reservoir below the Milli-Q.
If you are using a 30 or 60 or 100 Litre Reservoir from Millipore, then install a connector fitting which is
1/4 inch NPTM on one end and has an 8 mm tubing insert collar on the other end. This connector fitting
should be installed on the middle valve located on the bottom side of the 30/60/100 Litre Reservoir. The
Millipore fitting referenced above has an O-ring on its thread. You will not need to use Teflon Tape on this
fitting. Simply screw this connector into place.
Measure the distance between the Reservoir and the back of the Milli-Q. Allow some extra distance so the
Milli-Q could be rotated or moved without stretching the tubing. Cut an appropriate sized length of the black
8 mm OD tubing. The remainder of the length of the black 8 mm OD tubing will be used for the UF Reject
tubing.
Install one end of this tubing to the Reservoir. Push one end of the tubing into the collar of the fitting until it will
go no further. Pull on it slightly to insure it is fully seated inside the collar.
FEEDWATER IS FROM A PRESSURISED SOURCE SUCH AS A PIPE (A LOOP)
Get the roll of Teflon Tape and the 8 mm tubing (plus Screen Filter) from the Accessories Bag. Make sure that
the pipe end is a 1/2 inch NPTM connection. If this connection is not ready, then you will need to obtain the
proper fittings to be able to attach the fittings from the Milli-Q Accessories Bag.
Wind about 3 to 4 turns of Teflon Tape on the end of the pipe connection. The tape should be wound in a
clockwise direction (same direction the fittings will be turned).
Screw the Screen Filter to the end of the pipe. You may want to remove the attached 8 mm tubing to facilitate
the turning of the Screen Filter Assembly.
Measure the distance needed for the Feedwater Tubing. This is the distance between the Screen Filter and the
back of the Milli-Q. Allow some extra distance so the Milli-Q could be rotated or moved without stretching the
tubing.
Cut the appropriate length of 8 mm tubing as determined above. The remainder of the length of the black 8 mm
tubing will be used for the UF Reject tubing.
You will now need to install the Feedwater Pressure Regulator (Millipore Catalogue Number ZFMQ000PR).
Locate the Pressure Regulator. Turn it over so you can see the arrow that indicates the direction of water flow
through the Pressure Regulator. It is important not to reverse the water flow through the Pressure
Regulator.
The Pressure Regulator is installed between the Screen Filter (now attached to the pipe end) and the back of the
Milli-Q.
You will check and/or set the Pressure Regulator later (see Section 4-7 below). Normally, the Millipore
Pressure Regulator is pre-set to 0.3 bar and will not need adjustment.
You may want to flow some feedwater through the tubing and Pressure Regulator to check for leaks.
