CAUTION: Drilling any holes on the tank or flanges will destroy the tank! (Remember to use large diameter surface washers when mounting tank.)

It is very important that the Metering Pump (1) and Tank (6) are mounted on structural members such as the studs in the wall. The holes in the tank flanges are spaced at 16" on-center which should be the same as the vertical 2x4's in the walls. If these measurements do not work out at the same distance, you will have to first mount the tank to a small sheet of plywood or some 2x4's etc. then mount them to the wall.

Step 3:
Mount the Metering Pump (1) to the included Pump Mounting Bracket (8) using the #10 machine screws and nuts provided. Next, mount the Pump Mounting Bracket (8) to a structural member in as close of proximity to the Tank (6) as possible using the drywall screws provided. (Preferably directly under the tank.)
NOTE: The clear, vinyl hose coming out of the back of the Metering Pump is intended for overflow purposes in the event of an internal pump leak.

     

Step 4:
Install the ¼" hose fitting in bottom of Tank (6) using Teflon tape on pipe threads. Run the short 4' length of clear Nylon Hose (9) from this fitting to the Metering Pump (1) intake fitting located on the bottom of the Metering Pump. Install the 3-prong plug with 3-conductor wire (7) to the front of the Metering Pump (1) by first putting a generous amount of the dielectric silicone compound inside of the 3-prong plug. This is to prevent moisture from seeping into the plug causing corrosion.

          

Step 5:
Install Nylon Hose (9) to the outlet side (top) of the Metering Pump (1). Fish both the Nylon Hose (9) and the 3 conductor wire (7) out of the building usually by drilling a small hole down low by the bottom of the wall.
CAUTION: Be careful not to drill into any wires or pipes that may be hidden in the walls.

Step 6:
String the Nylon Hose (9) and the 3 conductor wire (7) from the outside of the building to the main sprinkler line. Do not leave the lines exposed. Bury them under the ground in a shallow trench or under the decorative garden rocks against the house.

Step 7:
Turn off the main water supply.

Step 8:
Cut the main sprinkler line to install the Flowmeter (2), Injector Tee (3) and Injector Nozzle (4).

WARNING    These must be installed downstream of the vacuum breaker or back-flow eliminator. This must be done to prevent back-flow of chemicals into the household or freshwater system. It is important to understand and comply with any state or local laws and building codes regarding back-flow preventers on fertigation systems!!

Step 9:
NOTE: Flowmeter/Injector assembly may already be assembled in some systems. If so, skip to Step 10. If not, follow instructions below.

Technique for assembly of the Flowmeter/Injector assembly will vary according to your sprinkler plumbing. Generally, one must first screw the Injector Nozzle (4) into the Injector Tee (3) using Teflon sealant or tape on pipe threads. Next, install the Injector Tee (3) downstream of the Flowmeter (2) by gluing both the Injector Tee (3) and Flowmeter(2) (wire-end up) together with a short piece of PVC pipe (included). This piece must be a minimum length of 5 times the diameter of the pipe being used. Install the long piece of PVC pipe (included) upstream of the flowmeter. This piece must be a minimum length of 10 times the diameter of pipe being used. This is done to insure flowmeter accuracy. Attach hose barbs at each end.
CAUTION: Be careful not to get any PVC pipe solvent or cement on the flowmeter impeller. The best way to avoid this is to apply the adhesive to the pipe and hose barbs rather than on the inside of the flowmeter tee itself which could result in excess glue getting on the impeller.

NOTE: If the irrigation water is not sediment-free a filter of approximately 150 mesh must be used upstream of the flowmeter to prevent flowmeter from clogging and not working properly.

Step 10:
Install the Flowmeter/Injector assembly to the pipe closest to the water supply line coming out of the house or building, downstream of the backflow preventer device, by using hose clamps on flexible sprinkler lines or PVC cement on hard PVC lines.

Step 11:
Install the Nylon Hose (9) that comes from the Metering Pump (1) outlet to the Injector Nozzle (4) hose end.

Step 12:
Connect the wires from the Flowmeter (2) to the wires from the front of the Metering Pump (1) by using the butt splice connectors provided or by soldering them and protecting them with electrical tape, heat shrink tube or weatherproof crimp-on connectors. All wires are connected Red to Red, Black to Black and White to White.

Step 14:
Run sprinkler system to check all connections for leaks.

Step 15:
Fill the Tank (6) with TechTurf™ fertilizer.

CAUTION: Using fertilizer not approved for use with the TechTurf system could result in severe damage to turf and/or system.

With sprinkler system running, plug Metering Pump (1) into 110 volt wall receptacle. Prime system by pushing and holding in the prime button on the face of the Metering Pump (1). Check to see that chemical (fertilizer) has reached the Injector Nozzle (4). If not, you may need to prime the Metering Pump (1) more. When chemical has reached the Injector Nozzle (4), pressurize the system by holding the prime button and check all chemical lines for leaks. NOTE: Sprinkler system must be on and running while performing priming procedure.

NOTE: If chemical Tank (6) is run until empty at any time, the system must be primed again according to the procedure described above.

For use of: 1" TT-C17 and 1" TT-A17 systems Set the pump dial according to how many days per week you are watering (See chart which follows).

Pump Setting		Days watering per week
Lowest setting (10%)		6-7
20%		5
30%		4
50%		3
100%		1-2*

(All numbers are based on 30 min. zone run times.)

* If watering only 1 day/week, the zone run time must be increased to 45 or 60 minutes, at a 100% pump setting, to obtain optimal results.

For suggested run times and pump settings consultant with your TechTurf™ dealer. Settings will vary for different fertilizer blends. Settings are controlled by the % of pump volume (from 20 to 100%) and by your sprinkler timer.
