Safety Precautions/Warranty Compliance
Warning:
Please read precautions thoroughly before operation. Must meet all
applicable local codes and regulations.
Remove Red Caps Prior to Installation
Your injector is 100% factory tested before delivery
and may contain a small amount of water. The three
red plastic caps are fitted after testing to ensure
cleanliness of the injector.
Before Applying Aggressive Chemicals
Please consult your distributor, chemical manufacturer
or contact Hydro's customer service to confirm
compatibility with your injector. Always wear
proper safety protection as recommended by
chemical supplier.
Label all Fluid Lines, Valves and Connections
If the solution that is being injected is not suitable
for drinking, all fluid lines should be labelled:
Warning - not for human consumption!
Monitor Outlet Flow
It is the user's responsibility to monitor the output
of chemical injected.
A Filter is Recommended and Required
Install a filter of 140 mesh (104 micron) or finer
depending on your fluid quality to prolong the working
life of the injector and for the warranty to be valid.
A filter is imperative since most fluid contains
impurities or particles, especially if the fluid source
comes from a well, pond or lake.
General Tips
Please read this instruction manual thoroughly. Following the procedures, will increase the life of your injector.
For A Long Service Life
Start with clean fluid by using an inline filter to reduce
impurities. Keep the solution container covered and
clean. Keep the suction tube filter 2" (5 cm) from
the bottom of the container. Perform maintenance
procedures as recommended (see Maintenance
page 10).
Liquid Concentrate, Soluble Product, Soluble and
Wettable Powder Use
Ensure that the chemical, when mixing with water,
is thoroughly mixed and/or completely dissolved
before using injector. For soluble and wettable powder
injection, it is recommended to use a Hydro WSP
injector or install a WSPL lower end conversion kit to an
existing Hydro dosage piston model injector.
Avoid a Potentially Hazardous Chemical Accident
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.
Avoid Solution Contamination
Use only clean FILTERED fluid. Do not allow
contaminants to enter the solution container. They
can be pumped into the fluid line and may cause the
spread of disease. Dirt, debris and other contaminants
in the solution container may cause excessive wear
to the unit.
Fluid Temperature
Min: 34°F (1°C), Max: 100°F (38°C)
Maximum Fluid Pressure
60 psi (4,1 bar)
Install a pressure regulator and/or pressure relief valve
to ensure operating pressure does not exceed the
maximum specification.
Before Removing An Injector From The System
Release fluid pressure. While the system is in
operation, turn off the incoming fluid 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.
Keep From Extreme Temperature
Protect the injector from freezing temperatures or
excessive heat.
Rinse Injector After Each Use
Additive allowed to remain in injector can dry out,
foul or damage the lower end at the next start-up
(see Maintenance page 10).
Injector Not in Use for an Extended Period
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.
