LOCATION: Locate waterer in a place sheltered from the prevailing winds for reduced energy consumption. Install the waterer 25 feet or more from self-feeders or bunk feeders to reduce the amount of feed and salt that is dropped into the waterer. WATER SUPPLY LINE: Horizontal underground waterline should be sized to account for any pressure drop relating to distance. The vertical supply pipe should be rigid plastic, copper or galvanized. We suggest you use a 1/2” (1.27 cm) pipe for hog waterers and a ¾” (1.91 cm) for cattle waterers. Water lines over 50 feet (15.3 m) should be one inch (2.54 cm), or larger. Use of undersized feeder pipe causes excessive pressure drop and loss of recovery capacity of waterer. Models are equipped with the following for supply connection: MH- ½ inch (1.27 cm), MC, MJ, and MK – ¼ inch (.635 cm) A shutoff valve should be provided under the waterer to shut off water when servicing. Flush supply pipe thoroughly before connecting to fountain. Water supply with foreign material such as sand, rust, etc. may require a filter to keep valve working properly. The full length of the vertical supply pipe must be centered in a 6-inch (15.3 cm) (or larger if the waterer will accommodate it) riser tile or PVC casing. Extend the tile from a point 1 inch (2.54 cm) above the top of your platform to a point below the frost line. DO NOT place insulation or other materials in the tile. This will stop the air flow and cause water line to freeze up. Consider using an insulated foam sleeve on the vertical supply line (not included). MOUNTING PAD: Waterer must be mounted on a concrete pad. The pad should be sloped about one-quarter inch per foot away from the waterer. We recommend a minimum thickness of four inches (10.2 cm). The size of the pad is left to the user’s discretion but we suggest you pour a pad large enough for livestock to stand on while drinking. This is about 8’ square (.75 square meter) for MC, MJ, and MK models and 16’ square (1.5 square meters) for model MH. An additional 4” to 6” pedestal (on top of the pad) extending 10 to12 inches from the waterer on all four sides will provide protection from livestock backing up to or rubbing against the waterer. It will also protect it from manure and manure handling equipment. A rough broom finish to the concrete surface provides a better footing for livestock. BE SURE TO PLACE A COPPER GROUND ROD TO USE IN GROUNDING THE WATERER AS SHOWN IN EXHIBIT A. THE WATERER MUST BE GROUNDED AT LEAST 8 FEET (2.4 meters) INTO THE GROUND. INSTALLATION 1 2 3 3 SETTING THE WATERER: Once the concrete is firm, mark the concrete for bolts by referring to Exhibits B, C, and D. Space the bolts so you can easily line up the inlet pipe connection in the waterer. It is advisable to make a template of the base of the waterer to check holes before the concrete is set. Alternatively, you may wish to mark the concrete after it has set and drill holes to hold the anchor bolts. Install four 3/8” (.95 cm) x 5” (12.7 cm) bolts (not included) in the concrete. When the concrete is dry, we recommend that you caulk (all weather sealant) the area of waterer base contact. This will prevent air from leaking under the waterer and decreasing energy efficiency. Also a sheet of aluminum foil placed over the concrete pad inside the waterer will reduce heat loss. Also a sheet of aluminum foil or an aluminum faced foam board (not included) placed over the concrete pad inside the waterer will reduce heat loss. 4
BASE DIMENSIONS 4 EXHIBIT B EXHIBIT C EXHIBIT D CONNECTION TO WATER SUPPLY LINE: See Exhibit E. On models MC, MJ, and MK, the valve in your waterer is connected to part number MC180 - 1/2 x 1/4 reducing elbow. The elbow is connected to either a 1/2” x 7” galvanized nipple (MC) or a 1/2” x 12” galvanized nipple (MJ and MK). The valve, the elbow and the nipple are assembled in the waterer. Part number MC183 flex hose assembly is in the valve hardware bag. It is 6 inches long. Connect the female end of the flex hose assembly to the galvanized nipple in the waterer and then to your water supply on the other end (and / or preferably the shutoff valve (not included) you installed to the top of your water supply). The flex hose is included to prevent frost heave problems. Make sure pipe or flex hose do not touch an outside surface of the waterer or the heater. On model MH, the valve is connected to part number OP2 3/4” x 1/2” reducing elbow. The elbow is connected to a 1/2” x 17” galvanized nipple. Connect your water supply (or shutoff valve) with a flexible hose (not included). Use Teflon tape or a compatible plumbers’ paste on all connections. 5 MJ MC/MK MH
VALVE ADJUSTMENT: Water flow is controlled to a degree by the size of the valve orifice (Ref No 5). More water flows with the VP26 1/4” orifice than with VP24 1/8” orifice. The two orifices are interchangeable without changing the valves. If you have low or gravity flow pressure, you might be able to use a VP26 orifice in a VP226 valve to get higher water flow. If your valve will not shut off completely, check your water pressure. The valve works best on water pressure up to about 60 psi. Higher pressures may require the installation of a pressure regulator. If the float bounces, valve chatters or there is a pounding noise in the water line when the water turns on or off, it can be due to an excessive amount of air in the water line. The best course probably is to consult an experienced plumber as there can be several options to correct this. If there are issues with valves, they tend to be related to high water pressure as discussed above. The origin of high water pressure issues tend to be rural or urban water systems. If your water source is your own well, low pressure is more likely to be an issue. Low water pressure from wells can have many sources including: low water yields from the well, size of the well casing, adequacy and working condition of the pump, pressure settings if available, size of distribution pipes among others. Consult a well driller or knowledgeable plumber. Higher pressures may require the installation of a pressure regulator. ALSO NOTE: If you purchased Models MC,MJ or MK, you are receiving our VP226 valve, which comes with VP24 orifice. VP24 orifice has an 1/8 inch opening. See Exhibit F. Also included with VP226 valve, is a small poly pack containing a VP25 orifice. If water drip is a problem and you believe you have done everything correctly- installation, controlled water pressure, etc, try VP25 orifice. It has a 3/32 inch opening. It flows about .5 to 1.5 gallons per minute. 7 6 INSTALL FLOAT: SEE EXHIBITS F AND G. Screw either VA225P 1 1/8” arm (MC, MJ, MK) or WC726P 3 5/8” arm (Ref No 10) into the boss on OP321 Float (Ref no 11). The hole on the float is not threaded. Make sure the arm is threaded in as straight as possible. Note that the float goes in the waterer in the vertical position. The arm can be tightened using VP115 (ref No 9) adjust screw (wing nut or thumb screw). You can alter the water level in the trough by changing the float position. Loosen the adjust screw and try various float positions until the desired level is attained. Tighten adjust screw securely. Place the valve cover, drain and refill the trough several times to ensure that the float arm operates freely. If the float tilts to one side or the other, loosen the assembly nut (Ref No 8) and turn the valve body slightly. If you still think there is interference, you may need to trim some insulation underneath of the cover. If you have high water pressure, it may be that the float will not always stay in the same position where you would like to have it. A star washer (not included) placed between the VP29 valve arm and the float arm will help secure the float at the desired height. Exhibit E 5 HEATER: Model 77 heater is installed on our MC, MJ, MK, and MH waterers. Model 77 is a 500 watt heater that plugs into a 120 volt outlet. It draws a maximum of 4 amps. The heater features a control knob which allows a range of 15 watts (at the lowest setting) to a maximum of 500 watts. You will probably never need to turn the knob more than about half way. The electrical supply line needs to be installed by a qualified electrician in accordance with all electrical codes. See the WARNING on page 1 and Exhibit A on page 2. When heat is not needed, we recommend that you unplug the heater. The heater is not thermostatically controlled. The heater is not immersible. Model 77 Utility Heater is warrantied for 18 months. Please return your warranty card. The serial number for your model 77 heater is found on the label which is around the control knob. Look for it just below the knob. If a new unit fails to operate after installation of the unit has been installed and working and then begins to freeze, check the following: Make sure the heater is getting 120 volts of electricity. Low voltage will reduce the heat put out. If no electricity is present, turn off the main fuse box for the unit. Check all wire connections to sure they are correct and tight. Check all fuses. Then, turn on the electricity. Make sure the water trough is clear of mud and silt. Mud can insulate and not allow the water to heat. If you are sure that adequate electricity is being delivered to the unit and there is still no heat, most likely the heater needs to be replaced. 8

WARRANTY ELECTRICALLY HEATED WATERERS AND ENERGY USE Our waterers are insulated with polyurethane foam with an R value of 7.14 per inch. Our foam contains no formaldehyde and is not attractive as a food source to vermin. Here is a check list of items to consider in the management of your waterer with regard to energy use 1. Inspect condition of wiring and insulation before each heating season. 2. Check waterers daily for cleanliness and proper operation of the water valve and heater. 3. In warm seasons, make sure excess condenstion is not forming inside the lower cabinet of the waterer which can contribute to the deterioration of insulation and the heater. 4. Counter the effects of cold winter winds with a wind barrier which will reduce energy consumption. 5. Repair leaking valves to eliminate wasting water which has already been pumped and heated. 6. Caulk or close up openings in the waterer cabinet especially around the foundation. 7. Make sure the electric service wires are of the proper size. 8. Make sure waterers are properly grounded to prevent leakage (as well as to ensure safety). OPTIMAL WATER TEMPERATURE: Studies have shown that there is little, if any, variation in daily water intake, feed intake, daily gain or feed efficiency with different water temperatures. Heating the water above say 40 degrees F in the winter will increase costs but there is no evidence to suggest improved animal performance. Animal water consumption is more dictated by ambient air temperature than by the temperature of the drinking water. Flow rates at discharge can vary depending on the diameter of the supply line, the distance water travels to the waterer, variability in water pressure, the buildup of deposits inside the water supply line among other factors.
