Introduction
TheMixRite pump injects functional additives into liquid medium systems using
a uniform repeating method.
Technical Data
Flow Rate From 10 to 2500 L/H (From 2.6 to 660 Gal/H)
Temperature From 4oC to 50oC
Water Pressure (intake) From 0.2 to 6 Bar (From 2.9 to 85 PSI)
Range of Rate of Additive between 0.2% and 2%
Maximum suction hight 3 meter
Operation
MixRite is powered by water flow, with minimal loss of pressure. The water
engine powers the proportioning unit. No external power is required.
The proportioning unit pumps liquid additives in direct relation to the
amount of water that passes through the motor and injects the additives into
the water system.

Installation of the MixRite
Installing the MixRite On a Direct Line (in line)
1. Install valves to the water line on each side of the pump.
2. Install a 50-75 mesh (250-300 micron) filter between the valve and the
pump intake.
3. Install recorder connectors to each of the pipes that connect to the
pump.
4. Attach the pump to the recorder connectors.
5. Position the liquid additive container 1-1.5 meter beneath the pump.
6. Check to ensure that the suction pipe is not bent or folded.
7. Position the drawing pipe into the additive container. Ensure that the
bottom.

Note: Ensure that the water flows into the MixRite in the
direction indicated by the arrows printed on the MixRite.

Installing the MixRite On a Bypass line (off line)
Where water is supplied at a higher flow rate, than the working flow rate of
MixRite must be installed on bypass line. The bypass provides the
possibility to close the operation of the pump while water continues to flow
through the line.
1. Install valves to the water line on each side of the pump and a third
valve on the direct line.
2. Install a 50-75 mesh (250-300 micron) filter between the valve and the
pump intake.
3. Install recorder connectors to each of the pipes that connect to the
pump.
4. Attach the pump to the recorder connectors.
5. Position the liquid additive container 1-1.5 meter beneath the pump.
6. Check to ensure that the suction pipe is not bent or folded.
7. Position the drawing pipe into the additive container. Ensure that the
bottom.

Mounting the MixRite
1. Prepare theMixRite site.
•TheMixRite intake and outlet must reach the intake and outlet pipes.
•The MixRite must be positioned 1-1.5 meters above the liquid
additives container.
2. Screw the MixRite bracket onto a wall or any stable vertical base.
3. Press the MixRite onto the bracket. The nipples on the MixRite must
click into the holes in the side of bracket.
Mounting the MixRite
Warning: During pumping, ensure that the additive container
is not completely empty.

Adjusting the MixRite
Every stroke of theMixRite moves a predetermined volume of water with a
predetermined volume of liquid additive. To adjust the volume of the liquid
additive:
1.
2. Preset the amount of additives according to the Percentage to Water
Scale that is found on the proportioner.
•Turn the Proportioning Adjuster clock-wise to increase the amount
of additives.
•Turn the Proportioning Adjuster counter clock-wise to decrease the
amount of additives.
3. Turn the Proportioning Adjuster slightly, until the U-latch holes of the
Proportioning Lock Nut align with the notches in the Proportioner.
4. Push the U-latch into the U-latch holes of Proportioning Lock Nut until
it is firmly in place.
Adjusting the MixRite
The Air-Bleed Valve
For proper operation, the MixRite should be free of air. Use the air-relief
valve on the cap of the MixRite to release trapped air. After initial operation
of the MixRite, apply pressure to the cap (the air release valve) for several
seconds to open valve that allows trapped air to escape. This air release is
accompanied by a slight loss of water. Release the pressure on the cap to
close the valve.

Rinsing and Cleaning the unit
Afterpumping
•Rinse the unit by pumping clean water from the additives container.
•Wash the external surface of the unit with clean water.
