WARNING
We know that you will be pleased with your decision to purchase a Brower waterer. Please take time to familiarize yourself with this
manual. Included are tips that will make use of your waterer more trouble free and more economical. Red and white Brower waterers
were marketed under the Marlor label for 25 years. Marlor waterers carried a light green and white color scheme. Brower parts will ser-
vice most Marlor waterers. This instruction manual covers the following model numbers: MC32E, MC32N, MK32HE, MK32HN, MJ31HE,
MJ31HN, MC32HE, MC32HN, MH30E, MH30N.

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 relat-
ing 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 re-
covery 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 thor-
oughly 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 ac-
commodate 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.
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 me-
ters) for model MH. An additional 4” (10.2 cm) pedestal (on top of the pad) extending 8 inches (20.3 cm) 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 pro-
vides 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.
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 tem-
plate 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.
CONNECTION TO SUPPLY LINE: Connect a hose or pipe fitting to the shutoff valve at the top of the concrete. Cut
hose or pipe to proper length and connect to waterer. A flexible connector should be used with a small “S” shape
to relieve strain if frost heaving is possible. An inflexible connection should use a “swing joint:” to prevent frost
heave problems. Hose or pipe should not touch the outside surface of fountain or heating element.
FLOAT ADJUSTMENT: The water level in the trough is varied by changing the float position. Loosen the wing
screw and try various float positions until the desired level is attained. If a relatively consistent water level cannot
be maintained, the problem is most likely a widely varying pressure (more than 20 psi) in the system. In such a
case the basic cause of the trouble must be corrected to get proper operation of the valve. Tighten wing screw
securely.
If the float, bounces, valve chatter, or you have a pounding noise in the water line when a waterer turns off or on, it
is usually due to an excessive amount of air in your water line. In most situations this can be corrected by using a
smaller orifice to cut down the water opening in your valve. (See paragraph 7).
After replacing the float and valve cover, drain and refill the trough several times to ensure that the float arm oper-
ates freely.

If the float should catch on any part of the waterer, its lateral position can be changed by loosening the large as-
sembly nut (VP15) and turning the valve body slightly. If float is rubbing on the insulation in the valve cover you
can trim the insulation with an ordinary knife.
VALVE ADJUSTMENT: All Brower pressure waterers are equipped with valves with interchangeable orifices when
shipped. This dependable valve has served our customers since 1975. The standard valve for your unit normally
operates on a range of 20 to 60 psi. When your waterer is installed on a gravity flow or low pressure system, you
may adjust your valves for more water volume by using a larger orifice in the valve. If your waterer is installed on a
high pressure water system (over 60 pounds) you may compensate for extra pressure by using a smaller orifice in
the valve. For severe high pressure situations, you may need to install a pressure regulator.
See EXHIBITS E & F for valve repair parts. Table 1 shows valve capacities in gallons per minute at various pres-
sures.

CAUSES OF INADEQUATE PRESSURE INCLUDE:
WELL DEPTH: If you have a shallow well, a deep well will probably solve the water shortage problem. If the
water-yielding capacity of the aquifer (water-bearing stratum) is less than your demand for water, install a storage
tank
SIZE OF WELL CASING: If you have a large pump on a small diameter well and the water output is slow, then
possibly your well diameter is too small.
PUMP NEEDS REPAIR OR REPLACING: Keeping equipment in good repair will assure an adequate water sup-
ply at all times. Often screens, foot valves, jets, etc, plug up after use
SIZE OF PUMP & PRESSURE SETTING: Before replacing your old pump or installing a new one, determine
your exact water needs, then select a pump based on that determination. One rule of thumb for estimating water
requirements in the home is that you need a gallon-a-minute capacity for every water outlet—faucet, sink etc.
DISTRIBUTION PIPES TOO SMALL: Long lengths of pipe and many pipe fittings can greatly reduce the pressure
at distant locations from the pump. Running a larger, new line to a distant location of high water demand will solve
the problem.
Consult a trusted well driller or plumber if you suspect any of the above problems.

ELECTRIC HEATING UNIT OPERATION
WARNING
If you have purchased one of the following waterer models—MC32E/MK32HE/MJ31HE/MC32HE—your waterer is sup-
plied with Model 77 Utility Heater.
Model 77 Utility Heater is a 500 watt heater that plugs into a 120 volt outlet. This heater has been used successfully on
farms for some 15 years.
The heater features a control knob which allows a range of 15 watts (at the lowest setting) to a maximum of 500 watts.
You probably will never need to turn the knob more than about half way.
The electrical supply line still needs to be installed by a qualified electrician in accordance with the electrical codes.
When heat is not needed, we recommend that you unplug the heater.
Model 77 Utility Heater is not immersible.
Model 77 Utility Heater is warranted for 2 years. Please return your warranty card. The Serial Number for your Model 77
Heater is found on the label around the control knob (look for it just below the knob).
TROUBLE SHOOTING FOR A QUALIFIED ELECTRICIAN ONLY:
If the new unit fails to operate after installation OR the unit has been installed and working and then begins to freeze up
check the following:
WATER FREEZES:

MC32E/MK32HE/MJ31HE/MC32HE HEATING ELEMENT
Make sure the electric unit is getting 115 volts of electricity. If no electricity is present, turn off the main fuse box
to the unit. Check all wire connections to make sure they are correct and tight. Check all fuses in the line and then
turn on electricity.
Make sure water trough is clear of mud and silt; mud can insulate and not allow heat to reach the water.
If you still cannot feel any heat at the element, your Model 77 needs to be replaced.
OFF SEASON MAINTENANCE: For extended life of the electrical unit, remove the unit from your waterer in the spring and
store in a dry area. Check the unit in the fall before installing in the waterer and you will have less trouble during the heat-
ing season.

TEMPERATURE ADJUSTMENT: The thermostat is pre-set at the factory for economical ice-free use (about 40ºF,
4ºC). To adjust your specific installation temperature, turn the temperature control knob clockwise to increase the
temperature of the water (1/4 turn equals about 4ºF). Only small adjustments should be made at one time. One
complete turn is the maximum at any one time. The small light in the thermostat will glow when the element is on.
To recalibrate you will need a container of water about 40ºF (4ºC). Place the sensory bulb in water. The indicator
light should come on. If not, turn adjusting screw slowly until light comes on. This will calibrate the unit to turn on
at approximately 40ºF (4ºC). It is advisable to remove the heating unit during the summer months. The minimum
summer precaution is to turn off electricity to the unit.
WIRE AND FUSE SELECTION: Check charts below for correct fuse size (Table 2) and wire size (Table 3) for your
specific waterer. All heating units are 115V-AC unless otherwise specified.

MH30E HEATING ELEMENT

TROUBLE SHOOTING FOR A QUALIFIED ELECTRICIAN ONLY: If the new unit fails to operate after installation;
OR the unit has been installed and working and then begins to freeze up; OR after installation of a new compo-
nent part, heating element, or thermostat, the unit fails to operate, check the following:
If none of the above results in proper operations, then:
WATER OVERHEATS:
Turn temperature control screw counter-clockwise —1/4 turn at a time and not over a ½ turn. Then check the wa-
terer in a couple of hours or the next morning. If the temperature is still too warm, repeat procedure.
If adjusting temperature control screw fails to correct overheating, replace thermostat. Return immediately if still
under warranty.
OFF SEASON MAITENANCE: For extended life of the electric unit, remove the units from the waterers in the spring
and store in dry area. Check the units in the fall before installing in the waterers and you will have less trouble dur-
ing the heating season.
The dealer you purchased your waterer from should normally have parts available. However, should he be tempo-
rarily out, he will order parts for you. Keep your equipment in good repair and it will give you many years of good
service. Please fill out the warranty card and return immediately.
Make sure the electric unit is getting 115 bolts of electricity. If no electricity is present, turn off the main fuse box to
the unit. Check all wire connections to make sure they are correct and tight. Check all fuses in the line and then
turn on electricity.
Make sure water trough is clear of mud and silt; mud can insulate the heating element and thermostat from the
water.
Turn temperature adjusting screw ¼ turn clockwise – check to see if indicator light is on – if not, turn adjusting
knob one more ¼ turn clockwise. One quarter turn is about 4ºF.
Check to see that the temperature sensing end of probe is submerged below water level but does not touch bot-
tom of trough.
If electric unit is on and the waterers still has freeze-up or icing trouble, check the line voltage at the unit when the
full load on that line is operating. Low voltage will greatly reduce the heating capacity of the heating element.

Turn off electricity at fuse box.
Remove cover from junction box inside waterer.
Completely remove the thermostat from the waterer to avoid short-circuit possibilities. Then wire the heating ele-
ment directly to your the heater to the black (hot) from your fuse box and green heater to green (ground).
Turn on electricity; if element heats, thermostat needs to be replaced.
Turn on electricity; if element does not heat, element must be replaced.

BROWER WATERERS AND ENERGY USE
As energy costs continue to escalate, more attention is being focused on products which are more energy efficient. We’ve been sell-
ing livestock waterers since 1963 and are continuing our tradition of leadership. Newly introduced is the best insulation on the market
which is standard on all automatic cattle waterers and hog waterers. Extra-thick insulation with an R-value of 7.14 per inch is used to
completely insulate the trough and jackets of our waterers.
WHAT IS R-VALUE: By definition, R-value is a “relative measure of resistivity to the flow of heat through a specific thickness of a par-
ticular material”. The higher R-value, the better. An R-value of 7.0 has twice the insulative value of an R-value of 3.5.
Please note the following R-value of competing insulation materials:
Material R-value Per Inch of Material
Polyurethane Foam 7.1429
Expanded Polyurethane 4.1667
Glass Fibre 2.6786
Mortar cement or sand & gravel aggregate .0833
Most of our competition is using expanded polyurethane.
POLYURETHANE FOAM, USED ON BROWER WATERERS, HAS THE BEST INSULATIVE PROPERTIES OF ANY MATERIAL USED FOR
WATERER INSULATION ON THE MARKET TODAY. Also, remember – polyurethane foam:
1. Contains no formaldehyde
2. Contains no protein (and is, therefore, not attractive to vermin as a food source.)
OTHER FACTS ABOUT POLYURETHANE FOAM: “Rigid polyurethane foams were among the earliest applications developed during
World War II, when their high strength-to-weight ratio was recognized and used for stiffening and strengthening aircraft components
adding very little weight gain to the resulting structure. The high strength-to-weight ratio, although an important attribute in many
applications, has been largely overshadowed by the outstanding thermal-insulating properties of low-density rigid polyurethane and
polyisocyanurate foams. Rigid polyurethane and polyisocyanurate foams exhibit among the lowest thermal conductivities of any com-
mercially available insulant. Their predominantly closed-cell structure resists water absorption, condensation, and wicking (transport
by capillary action) and provides positive buoyancy in marine applications. They will not sag, buckle, pack down, or mat from ordi-
nary use. They are resistant to fungi and mildew. They can be applied easily on the job site by spray, froth, or pour techniques, or as
lightweight panels that can be cut and trimmed with ordinary hand tools common to the building trades. They are highly resistant to
weathering, oxidation, ozone, oils and most fuels. Because of these advantages, polyurethane elastomers have replaced natural and
synthetic rubbers in many applications where they have outlasted rubber factors of 10 times or more.”

TIPS TO SAVE ENERGY—SIMPLY AND INEXPENSIVELY: Energy used for freeze prevention can be reduced by better temperature
control, insulation, unit selection, location and water preservation. While producers must assure a continually available water supply,
good management can significantly reduce livestock watering costs.
The national Food and Energy Council made a checklist for producers to improve their waterers with a farm energy analysis program.
The first checklist can be completed at no cost to the producer. The second checklist has some low-cost maintenance practices, and
the third checklist is for those wishing to make improvements or investments in their watering system.
NO COST
1. Inspect condition of wiring, insulation and burner before using heaters each fall.
2. Check waterers daily for cleanliness and proper operation of the water valve and heating elements.
3. Make certain covers operate freely and close completely to minimize heat loss in winter.
4. Set the thermostat below the temperature of incoming water or slightly above freezing.
5. Provide natural ventilation of enclosed compartments, in summer, to reduce deterioration of insulation, wiring burner or re-
lated equipment.
LOW COST
1. Use a wind barrier to protect the waterer from the direct effect of cold winter winds.
2. Provide covers (insulated if possible) for all water surfaces.
3. Replace leaking float valves immediately to eliminate wasting water that has already been pumped and heated.
4. Replace or quickly dry any insulation that becomes wet.
5. Replace or add insulation to waters with less than two inches of insulation.
6. Insure that insulation is well protected from damage by livestock and rodents.
7. Caulk or close up openings in the waterer enclosure, especially around the foundation.
8. Paint the exterior a dark color to absorb heat in winter

IMPROVEMENT OPTIONS
1. Install the waterer with an insulated thermal break between the waterer and the concrete foundation to prevent transmitting
heat to the floor.
2. Install the waterer over a 12- to 20-inch tile extending from the waterer base to below the frost line.
3. Buy well-insulated waterers with lids when replacing old units.
4. Take special care in selecting new waterers so that the drinking area size is matched to the type and numbers of animals
being served.
5. Be sure that electric service wires are of the proper size to ensure maximum efficiency.
6. Insulate electric heat tapes.
7. Make sure that all electric waterers are properly grounded to prevent leakage and to enhance safety.
8. Make sure that water lines serving the waterers are the correct size to minimize energy.
OPTIMAL WATER TEMPERATURE: A recent study at Kansas State University examined the effect of water temperature on animal per-
formance and compared electric costs for water heating.
The test results showed no difference in daily water intake, feed intake, daily gain or feed efficiency with different water temperatures.
Heating the water above 40 degrees increased cost of production, yet failed to improve the performance of the cattle. It appeared that
the amount of water consumed by the animals was more dictated by daily minimum ambient air temperature than by the temperature
of the drinking water.
