Your injector is 100% factory tested before delivery and
may contain a small amount of water. The three red
plastic caps are tted after testing to ensure cleanliness
of the injector.
Please consult your distributor, chemical manufacturer
or contact Dosmatic's customer service to conrm
compatibility with your injector. Always wear proper safety
protection as recommended by chemical supplier.
If the solution that is being injected is not suitable for
drinking, all uid lines should be labeled:
It is the user's responsibility to monitor the output of
chemical injected.
Install a lter of 140 mesh (104 micron) or ner
depending on your uid quality to prolong the working
life of the injector and for the warranty to be valid. A
lter is imperative since most uid contains impurities or
particles, especially if the uid source comes from a well,
pond or lake.
Safety Precautions
Warranty Compliance
General Tips
Start with clean uid by using an inline lter to reduce
impurities. Keep the solution container covered and
clean. Keep the suction tube lter 2" (5 cm) from
the bottom of the container. Perform maintenance
procedures as recommended (see Maintenance page 10).
Ensure the chemical is completely dissolved before
starting the injector. If necessary, dissolve the chemical
in hot water and allow to cool before using. Failure to
thoroughly dissolve the chemical will cause premature
wear to the dosage piston and the inner cylinder.
!
, Please read precautions thoroughly before operation. Must meet all
applicable local codes and regulations
Select a safe location. Chemical container should be
kept away from children and/or high usage areas and
the location must also not be susceptible to freezing
temperatures.
Use only clean FILTERED uid. Do not allow contaminants
to enter the solution container. They can be pumped into
the uid line and may cause the spread of disease. Dirt,
debris and other contaminants in the solution container
may cause excessive wear to the unit.
Min: 34°F (1°C) Max: 100°F (38°C)
0.4%, 1%, 2.5%, 5% - 140 psi (9,7 bar)
10% & 20% models have maximum operating pressure
of 65 psi (4,5 bar).
Operating pressure and ow are reduced while using
remote injection kit.
Install a pressure regulator and/or pressure relief valve to
ensure operating pressure does not exceed the maximum
specication.
Release uid pressure.While the system is in operation,
turn off the incoming uid valve. Leave the out going
valve open this will relieve the pressure at the injector
and all parts of the system after the injector. Injector is
now safe to remove.
Protect the injector from freezing temperatures or
excessive heat.
Additive allowed to remain in injector can dry out, foul
or damage the lower end at the next start-up (see
Maintenance page 10).
If the injector has not been stored properly deposits may
have dried onto the motor (see Maintenance page 10).
Before operation, soak entire unit into room temperature
water approx. 72°F (22°C) for an eight hour period.
