Minimist Installation Instructions

Put the pumping system/reservoir in an area that has access to a 110 volt outlet and a water supply. If the installation is in a large facility: the pumping system/reservoir should be placed as close to the center of the facility as possible. Or the shortest distance to the most distant nozzle. This will keep line pressure loss to a minimum.  

If there is no air movement in the building, and ceiling height is under 10 ft., tilt nozzles at alternating 30 degree angles whenever possible. This will improve lateral movement of the insecticide spray.

If windows and doorways are not open, or if there is no air movement in the building, it is suggested that a fan or fans be installed for air circulation. This will also in spray dispersion and provide increased insect kill.

Do not place nozzles in front of or with-in 10 ft. of exhaust fans.

Do not place nozzles to spray directly on animals, drinking cups, feed mangers or bunks.

Nozzles should be centered between and a minimum of 3 ft. above any dairy cows.

In controlled environment buildings, contact United Spray Systems, Inc. if you have questions on air movement. Examples: poultry houses, veal barns, calf nurseries and some farrowing barns.

Assembly

	1. Unpack all materials and check that all pieces have arrived in good condition. System box should include: Pumping unit (motor/pump, timer on bracket) Suction tubing attached to suction filter Mounting hardware (located in pump mounting feet and timer bracket)
	2. With the reservoir lid removed, secure the pump assembly and timer to the reservoir lid using mounting hardware supplied (see reservoir lid diagram for location). Tighten firmly with a wrench.
	3. Using the reservoir lid diagram locate the "suction line" hole in the lid. Using your fingers, push the supplied 3/8" tube/suction line (tubing with suction strainer attached to it) through the reservoir lid from the bottom side and up into the Presto-loc 3/8" male elbow fitting in the pump until it is secure. Remember - push the tubing firmly in to the fitting, making sure it is secure. No tools are necessary.
	4. Using the reservoir lid diagram, locate the "return line" hole in the lid. Using your fingers, push the 1/4" return tube that is attached to the needle valve on the pump through the reservoir lid from the top.
	5. Secure the nozzles and tubing to the ceiling or rafters using electrical staples / plastic ties on both sides of the nozzle tee�s and one on the side of the elbow nozzles.
	6. Making sure the tubing is cut straight, attach a coil of 1/4" tubing to the Presto-Loc pressure fitting on the pump, see picture at the left. Push the tubing into the fitting firmly making sure it can not be pulled out. Run the tubing from the pumping unit out to the first nozzle. Place an electrical staple over the tubing approximately every 5-6 feet between nozzles to prevent the lines from sagging. Continue installing the tubing from one nozzle to the next, following your system design, until all nozzles are plumbed with tubing.
	7. After all fitting and tubing connections are made, the system is now ready to test. Remove the reservoir lid. Fill the reservoir 1/2 full with water. Replace the reservoir lid. Plug the systems power cord into 110 Volt outlet. Flip the manual/auto switch (see the timer diagram) to manual. With the system running, turn the pressure adjusting needle valve on the return line in a clockwise direction to increase or counter-clockwise direction to decrease the pressure until the gauge reads about 140 PSI. The needle valve should be positioned to an almost closed position to achieve proper pressure. Closing the needle valve all the way will cause the pump to cavitate and the gauge will bounce. The 140 PSI will not be reached until the system purges all air out of the tubing lines and nozzles. While all nozzles are operating, check that there are no leaks at any connections. If no leaks are found, unplug the power cord and once again remove the reservoir lid.
	8. With the reservoir lid removed, add your insecticide concentrate according to the instructions on the insecticide label, then continue to add more water until the solution is about 5 inches from the top of the reservoir lid. Replace the reservoir lid.
	9. Now determine how many spray cycles are desired per day and at what times they should occur. Normally 3 to 6 spray cycles per day. All spray cycles should be set to run between 6 AM and 9 PM daily. Press the tabs in toward the middle of the timer dial at each desired cycle time (see picture to the left). When the timer tabs are positioned, rotate the timer dial in a clockwise direction only, to the present time of day.
	10. Next, set the small timer dial (small black knob) to the desired amount of spraying time, normally 45 to 60 seconds.
	11. Plug the power cord back into a 110 volt outlet. The system is now operational and will spray automatically at the preset intervals.
	NOTE: If power is lost due to storms, ETC...., when power is restored simply rotate the large timer dial clockwise to reset the time of day and normal operation will continue.

Winterizing


1. Remove steel band from reservoir lid.

2. Remove reservoir lid (with pumping unit still attached) from reservoir or slid it to the side making sure it does not fall into the reservoir.

3. Pull the suction line out of the liquid in reservoir.

4. Make sure you are using an environmentally safe product to winterize your system. Dump the environmentally safe anti-freeze in to a one gallon or larger pail, then place the suction line in the bucket, also making sure that the return line discharges into the same pail.

5. In the timer assembly move the "manual" switch to the on position. Manually run the pumping unit until the environmentally safe anti-freeze has filled all tubing lines and nozzles. Once all the insecticide has been purged and you see the environmentally safe anti-freeze coming from all nozzles, move the "manual" switch to "auto".

6. Unplug power cord. Pull the suction line out of the environmentally safe anti-freeze. Replace the suction filter. Using a cable tie, tie the suction filter to the suction tubing just under the lid. (Do not allow strainer to stay in liquid over winter months. Freezing may damage it.)

7. To de-winterize the system, stir insecticide in barrel, untie and place suction filter in insecticide liquid... Plug power cord in ... Set time of day on clock timer... Set pins for spray cycles desired... Start power unit manually and run it until all environmentally safe anti-freeze is purged from the system...Move "manual" switch to "auto"...the system is now ready for automatic operation.
