2.O1 Installation & Start-up
Fluid Filter (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. Hydro Systems
recommends a Twist II Clean
®
filter that can be ordered with
your injector.
Mounting Injector
Securely fasten your injector to a solid object such as a wall or
in a cold fluid line. Note arrow on injector indicates fluid flow.
Backflow Preventor (Recommended)
Install one that meets local code requirements.
Pressure Safety Release Device (Recommended)
Prevents pressure from exceeding specifications of the unit.
Bypass Valve Set-up (Recommended)
Allows the injector to be taken off-line for maintenance
or storage when not in use.
Fluid-Hammer Arrester (Recommended)
Prevents fluid-hammer damage to the injector when
operating quick closing solenoid, pneumatic or hand-
operated ball valves on the fluid system.
Anti-Siphon Valve (Optional)
To prevent solution from being siphoned out (from the
solution container) into the feed lines when the upstream
valve is shut off. The anti-siphon valve must be installed on
the downstream outlet.
Additional Siphoning Prevention
Place solution container on a level below the injector suction
tube fitting. Using the inlet side as a shut-off valve could cause
full strength solution to siphon into the feed line.
Solution Container
Use any size container. A lid or cover is recommended.
To connect your solution container, gently push the end of
the suction tube onto the bottom of the suction tube fitting
assembly. Place the filter into the solution container at least
2" (5 cm) from the bottom and fill with at least 2" (5 cm) of
chemical solution.
Never Use Petroleum Based Lubricants
The injector is shipped with a thin coat of silicone around
the seals for ease-of-assembly. Petroleum based lubricants
such as Vaseline © , baby oil, WD40 © , or motor oil on
the O-rings or any part of the injector should never be
used as this can cause particles to adhere and clog or
damage the injector.
Check System for Leaks and Start-Up Procedures
Open the bypass valve (A), close inlet valve (B) and outlet valve
(C) to prevent fluid flow into the injector. SLOWLY turn on the
main fluid line. Run fluid flows between 5 -10 gpm (1100-2200
l/hr) through the plumbing system. Turn on all of the valves
located downstream from your injector to release trapped air.
SLOWLY turn on the inlet valve (B). Open the outlet valve (C)
and close valve (A). As fluid travels through the injector, you
will hear a “clicking” sound. Check for leaks and correct
if necessary.
