Installation And Start-Up; Suggested Installation Diagram - Dover Hydro Systems SuperDos 45 Manual De Operación

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.
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" (5cm) from
the bottom and fill with at least 2" (5cm) 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 -12
gpm (11-45 l/m) 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.
