Operations
Clicking Sound is Normal
Fluid flowing through the injector will automatically cause
the injector to “click” and inject a set amount of solution
into the fluid line. The higher the flow rate the more
frequent the "clicking". The injector is designed to inject
solution proportionally (at the same set ratio) regardless of
fluid flow. Maximum number of clicks per 15 seconds
is 50.
Service Fluid Flow
Fluid flow and pressure must be within the established
specifications (see Specification on page 4) for your
model.
Change Feed (Injection) Rate
The feed rate on the injector is adjustable
EVEN WHILE
OPERATING AND UNDER PRESSURE
. To change feed
rate see (Fig. 1 and Fig. 2). Do not remove #79 when
injector is under pressure.
1. Lift lock ring on (#7) (Fig. 1).
2. Rotate Ratio Adjuster Sleeve (bottom of #7) (Fig. 2) up
or down to the desired setting. Use arrows at top of the
Ratio Adjuster Sleeve to line up with the desired feed rate
on the sleeve.
3. Return ring to lock position by pushing down on ring.
NOTE: Do not screw Ratio Adjuster Sleeve below lowest
setting line. Measure outlet fluid to assure desired feed
rate is being delivered.
Bleed Port
Ensure all air is out of the unit by pressing the bleeder
button in until water comes out. Release bleeder button
to stop water from flowing out of bleed port.
