IMPORTANT SAFETY INSTRUCTIONS
WARNING: To reduce the risk of electric shock, burns, serious injury or death to persons when
using the Pasteurizer, follow these basic precautions:
1. Read all instructions before using the Pasteurizer.
2. Do not operate the pasteurizer without water covering the heating elements at all times.
3. Always disconnect the electrical power before attempting service. All power sources must be
disconnected before the cover is removed for repair.
4. Do not allow children to operate or play around the Pasteurizer. Close observation of children is necessary
when the unit is used with children nearby.
5. Do not reach into the Pasteurizer when the power is on and the paddle is turning as this can cause serious
harm.
6. Hot Surfaces include the water, baskets, motor, propeller, Perfect Udder bags, electrical fixtures, hoses,
heating elements, draining water and the colostrum. Touching these surfaces during operation may result
in severe burns. Do not touch hot surfaces.
7. This equipment is designed to operate in an ambient temperature range of 35°F - 104°F (2°C - 40°C),
altitude up to 6560 ft (2000 m), maximum relative humidity 80% for temperatures up to 88°F (31°C)
decreasing linearly to 50% RH at 104°F (40°C), for indoor use only.
8. Do not try to change unavailable settings in the pasteurizer controller without consulting a technical
expert at Dairy Tech, Inc.
9. Do not repair or replace any part of the Pasteurizer or attempt any servicing unless specifically
recommended in the trouble-shooting portion of this manual. Any modifications made to the unit beyond
these instructions will void all warranties.
10. Always clean the unit immediately after each use, according to the instructions in the “Cleaning of your
Pasteurizer” section of this manual. Build-up of residue on the propeller or tank will decrease heating and
cooling efficiency, as well as harbor potentially harmful pathogens.
11. During the heating cycle, always make certain the Pasteurizer lid is closed.
12. Use the pasteurizer only for its intended purpose. DO NOT use for milk intended for human consumption
as this product has not been approved for such use.
13. Do not touch the motor, hoses, lid, handle or brass fittings while the unit is hot and working.
14. Do not attempt to tilt the machine while it is full. It is extremely heavy and can cause severe injury to the
operator.
15. To prevent severe burns to employees or calves, always allow the colostrum to cool completely before
handling or feeding to calves.
16. The Pasteurizer must be electrically grounded. DO NOT modify the plug that is provided with the
Pasteurizer. Always have a certified electrician confirm proper power supply and connections.
17. The pasteurizer must be installed on a level surface to evenly distribute weight to all the support
structures.

RECEIVING YOUR PASTEURIZER
Use care when unpacking your Matilda® Model pasteurizer. It will have arrived in one box or crate.
Please make a note of any cautionary labels that are used on the carton suggesting orientation, where
to cut with a knife, fragile, etc.
INSTALLATION
WARNING: INSTALL THE UNIT ACCORDING TO THE INSTALLATION INSTRUCTIONS. TO REDUCE THE RISK OF FIRE,
ELECTRIC SHOCK, SERIOUS INJURY OR DEATH TO PERSONS, READ THE IMPORTANT SAFETY INSTRUCTIONS BEFORE
OPERATING THIS PASTEURIZER.
BEFORE USING THIS UNIT FOR THE FIRST TIME, WASH OUT THE INSIDE OF THE SINK WITH HOT SOAPY WATER AND RINSE
CLEAN.
Choosing and Preparing a Location
Criteria for Selecting a Location
a) Choose an indoor spot that will be protected from the elements. Extreme heat and freezing
temperatures will damage the unit.
b) Cold water is required to be connected to the unit for water cooling the Perfect Udder bags. A
hot water source is not necessary for use of the equipment, it makes its own hot water.
c) Floor drains will allow for proper cleaning and rinsing of the product as well as to clean up
colostrum spills.
d) Power requirements are single-phase, 240 VAC, 30 A circuit breaker rated for use as branch
circuit protection. Three-phase connections are also available.
e) Floor space or shelf space requirements are approximately 24” (60 cm) wide x 36” (90 cm) deep.
f) Avoiding extremely drafty areas will improve heating efficiency of the unit.
g) Always have 2 people lift and carry the unit grasping with both hands on the sides of the unit.
Never attempt to move the unit while it is full of water.
h) Operating weight of Matilda® is approximately 250 lb (113 kg). Be certain that tables, shelves or
other surfaces can support the weight.

7
CONNECTING THE HOSES FOR WATER-COOLING
Cold Water Connection: A 6’ (1.8 m) black supply hose is supplied with the machine. This hose with
factory ends supplies all the cold water to cool the product when pasteurization is finished. It can
connect to any normal domestic pressure cold water source including a hose, but it MUST BE ON AT
ALL TIMES DURING OPERATION. Using the supplied hose, attach one end to the threaded solenoid
valve on the back of the unit, with the other end going to a regular hose bib supply. NOTE: If water
pressures exceed 80psi (5.5BAR), install a pressure reducer.
WATER DRAIN: This 4’ black hose must be connected to the back of Matilda® as shown in the image
using the provided clamp. It should be directed to a drain, cistern, stock tank or other collection
system. Do not connect the drain hose to another hose or to any system that can create back-
pressure. This will prevent proper cooling and will cause the machine to overflow which may damage
sensitive electrical components and void your warranty. If you wish to salvage the waste water direct
the drain line to a 5-gallon bucket and place an inexpensive sump pump in that bucket to send water
where it needs to go.
It is important to keep water turned on anytime the pasteurizer is in operation to prevent damage to
the heating elements.

8
CLEANING THE SYSTEM
NOTE: NEVER SPRAY MATILDA® WITH WATER!! Serious Electrical System Damage can
occur and will void your warranty.
Be sure to DISCONNECT FROM POWER BEFORE cleaning.
HELPFUL TIP: Always keep the doors closed to prevent flies, insects, Matilda® must
be cleaned periodically. We recommend every few days, but it depends on
contamination due to dirty bags, broken bags and poor water quality.
Do not use abrasive cleaning pads or solutions. Do not use cleaners containing ammonia, organic
solvents, or potassium hydroxide
1. Begin by lifting both lids and remove the wire baskets from each side. The baskets can then be
cleaned outside of the unit with a soft brush and disinfectants.
2. Lift the drain handle, turn it 90°, then lower it into the collar to lock it open while the contents
drain out the back of the machine.
3. Perform a warm water rinse to remove dirt and grime.
4. Once the surfaces have been cleaned, perform a final hot water rinse.
5. Periodically, but at least monthly, utilize a sanitizing/disinfecting product like Effercept® to
destroy any biofilm that may be developing on the surfaces of the equipment. Make sure that
the product is safe for plastic surfaces. Spray generously and allow to air dry.
Air Filters
Matilda® has 4 air filters that are located in her
bottom enclosure panel. We recommend that you
clean these filters when you clean Matilda®.
1. After you have finished cleaning Matilda®,
and BEFORE filling her with water, tip her up
to reveal the Bottom Enclosure Panel.
2. Remove the 4 air filters and remove
anything that restricts air flow.
3. Rinse the air filters with clean water and re-
install.
Once the unit is dry and clean, lower the drain and
turn the machine on so it can once again fill with
water and prepare itself for use.
Terminal Blocks
Annually have a qualified electrician inspect and
tighten the screws in the terminal blocks in the
back of Matilda. Make sure power is completely
disconnected before opening the electrical access panel.

WATER QUALITY
POOR WATER QUALITY WILL HAVE AN ADVERSE EFFECT ON HEATING ELEMENT LONGEVITY AS WELL AS THE OTHER
COMPONENTS OF THIS EQUIPMENT THAT ARE IN CONTACT WITH WATER OF POOR QUALITY.
Dairy Tech Inc is not responsible for your water quality and the effects that it may have on our equipment.
If you have poor water, dirty water or hard water, purchase and install a water filtration/softener system.
DAIRY TECH RECOMMENDS THE FOLLOWING STEPS:
1. Test a sample of water that will be used with the Dairy Tech equipment. Local experts will be able to tell you if
your water quality will be detrimental to electric heating elements and other components of our system.
a. If the starting water quality is acceptable, take additional samples at monthly intervals to help determine
how often to replace the cartridges in your system
b. If your water quality is NOT acceptable, install the water filtration/softener system and replace cartridges
every 3 months or anytime they are visibly dirty, or if water flow is compromised.
THIS SYSTEM WILL NOT REMOVE CHEMICALS OR DISINFECT WATER AND IS NOT INTENDED FOR DRINKING WATER.

10
ELECTRICAL REQUIREMENTS
The electrical supply cord is not included with your purchase due to many jurisdictions that require
installation only by certified electricians. It may be purchased separately and installed on your farm.
Local ordinances and electrical codes will dictate wire sizing, lengths and connections including the
need for power kill switches in some locations. Always check with your local electrician for installation
assistance. Carefully review the decal on the inside of the rear panel to see which power supply your
Matilda® is prepared for per your ordering instructions. Instructions and a wiring diagram are provided
for your benefit but always call our service department for additional assistance. Failure to meet these
requirements will void the warranty and could result in serious damage to the unit, bodily injury or
death. The receptacle may need to be fitted with a water-resistant cover for added protection.
ALL CONNECTIONS SHOULD BE PERFORMED
BY AN ELECTRICIAN OR OTHER TRAINED PERSONNEL.
•The receptacle should be sharing minimal usage with other equipment to avoid unexpected outages and tripping of the
breaker. If the power is lost, but returns within 1 hour, the cycle will resume automatically in most instances.
•Check your electrical system to make certain it is properly grounded to avoid the possibility of electrical shock.
International Installations:
Matilda® can utilize a variety of power sources. Consult the wiring options diagram in this owner
manual (page 35) as well as those on the machine for further instruction and options. Follow the labels
attached to the back of the machine for specific wiring instructions in these instances.

11
External Circuit Breakers
The unit is equipped with 6 external circuit breakers on the back of the unit. These circuit breakers
protect both sides of the heating elements from internal and external damage. The layout of the circuit
breakers is shown below, as well as on the unit itself. Refer to Trouble Shooting for further
information.
Internal Fusing
There are 2 internal fuses that protect the internal power supply. They are located in DIN mounted
holders labeled F1 and F2 as shown in this image.

12
ENERGY AND TIME SAVING TIPS
1. Pasteurize the colostrum as quickly as possible after collection. This will prevent the excessive growth of bacteria in
the colostrum and also take advantage of the heat to improve energy efficiency.
2. Avoid placing the unit in an area of high drafts to prevent convection heat losses while pasteurizing.
3. Colostrum can be stored in the refrigerator for 24-48 hours if it is handled cleanly once it has been pasteurized.
Filling Perfect Udder® Colostrum management bags allows for a disposable system that makes it easy to keep track
of dates and colostrum quality. These bags also allow the product to be warmed more quickly when they are
needed for the newborn and can then be fed without recontamination of the product. Order more bags from your
local veterinary supply dealer or online at www.perfectudder.com
4. Do not try to use plastic calf bottles in Matilda®. It is impossible to transfer heat across the thick plastic to ensure
adequate pasteurization.
5. Always wear nitrile or latex gloves when handling the colostrum to prevent the spread of pathogens from your skin
surface.
6. Keep the lids closed on Matilda® when not in use. This will keep the heat inside and also prevent contamination
with dirt and insects.
7. Water quality is very important. The heating elements will be inefficient if deposits begin to build up and they will
also experience early failure. If signs of poor water quality exist, we recommend a filter and water softener
combination (part no. K-WaterFiltration-System) available at www.dairytechinc.com
8. Matilda® can be turned off during non-busy times to conserve energy.
WHEN SERVICE IS REQUIRED
If you purchased Matilda® from an authorized dealer, contact them directly with inquiries or repair questions.
For prompt service, work through the troubleshooting guide in this manual to give an accurate description of
the problem.
The Dairy Tech, Inc. service department can also assist when needed 1-866-384-2697 extension 2
Repair by an unauthorized service technician will void the warranty.
