How To Install the Tubing and Fittings
4.3.1
Inlet Tubing - (Compression tube models)
-Locate the inlet fitting of the Pump Tube, see fig 6.1.
Remove the tube nut. Push the clear PVC suction tubing onto the compression barb of the fitting. Use
the tube nut to secure the tube. Hand tighten only.
o
Inlet Tubing - (Quick-Connect models)
- Locate the black, 90 elbow, low pressure Quick-Connect
inlet fitting, see fig 6.1. Connect the clear suction tubing to the hose barb. Check that the O-ring is in
place on the Pump Tube fitting and press the Quick-Connect fitting onto the Pump Tube. The fitting
should securely click in place.
4.3.2
Strainer
-Trim the inlet end of the suction tubing so that the
strainer will rest approximately two inches from the bottom
of the solution tank. This will prevent sediment from clog-
ging the strainer. Slip the ceramic weight over the end of the
suction tube. Press the strainer into the end of the tube.
Secure the ceramic weight to the strainer. Drop the strainer
into the solution tank.
4.3.3
Outlet Tubing - (Compression tube models)
- Locate the
outlet fitting of the Pump Tube, see fig 6.1. Remove the tube
nut. Push the opaque outlet (discharge) tubing onto the
compression barb of the fitting. Use the tube nut to secure
the tube. Hand tighten only.
Outlet Tubing - (Quick-Connect models)
- Locate the
beige, high pressure Quick-Connect outlet fitting, see fig 6.1.
Remove the metal tube retaining nut from the Quick-Connect
fitting and slip it over the end of the opaque outlet (discharge) tubing. Connect the tubing to the hose
barb located on the fitting. Secure the tube to the fitting with the metal nut. Check that the O-ring is in
place on the outlet end of the Pump Tube and press the Quick-Connect fitting onto the Pump Tube. The
fitting should securely click into place.
Trim the other end of the outlet tube leaving only enough slack to connect it to the injection/check valve
fitting. Increasing the outlet tube length increases the pressure at the pump tube, particularly with
viscous fluids.
Keep the outlet tube as short as possible.
4.3.4
Injection/Check Valve Fitting Installation
- The Injection/Check valve fitting is designed to install
directly into either 1/4” or 1/2” female pipe threads. This fitting will require periodic cleaning, espe-
cially when injecting fluids that calcify such as sodium hypochlorite. These lime deposits and other
build ups can clog the fitting increasing the back pressure and interfering with the check valve operation.
See section 6.0.
Install the Injection/Check valve directly into the piping system. Do not use a pipe stud with a tee for
insertion of the injection valve. The solution must inject directly into the flow stream.
Use Teflon thread sealing tape on the pipe threads. Push the opaque outlet (discharge) tubing onto the
compression barb of the Injection/Check valve fitting. Use the tube nut to secure the tube. Hand tighten
only.

How to Adjust The Output -Digital Timers (fig. 5.1)
5.1.1
Digital Programmable Timer Model
- The pumping mechanism is turned on and off by an electronic
cycle timer. The total-time cycle is adjustable from 1.0 seconds through 99 seconds. The on-time cycle
is adjustable from 0.5 seconds through 99 seconds. Example: If the total-time cycle is adjusted for 90
seconds and the on-time cycle is adjusted for 5 seconds, the pump will run for 5 seconds and turn off for
85 seconds (90 second total cycle). This cycle is repeated until either the standby button is pressed, the
cycle time is changed or the input power is disconnected from the pump.

(Total Time Cycle) = ON-TIME CYCLE
EXAMPLE:
Model A1N10D-6Q has a maximum flow rate of 1.42 oz. per minute.
How do I adjust the pump to inject .5 ounces of solution per minute?
