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 turn on the pasteurizer without rst lling with water
around the heating elements as directed on page 12.
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 lid, plumbing xtures, electrical
xtures, hoses, heater body, milk cabinet surfaces, draining
water and the milk or colostrum. Touching these surfaces
during operation may result in severe burns.
7. This equipment is designed to operate in an ambient
temperature range of 35°F (2°C) – 100°F (38°C), altitude up to
2000m, maximum relative humidity 80% for temperatures up to
31°C decreasing linearly to50% RH at 40°C, for indoor use only.
8. Do not try to change the 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 specically recommended in the trouble-
shooting portion of this manual. Any modications 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 eciency, as well as harbor
potentially harmful pathogens.
11. During the heating cycle, always make certain the Pasteurizer
lid is rmly seated on the pot of milk. The lid will be hot. Do not
touch while in operation.
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 tank of milk, motor, hoses, lid, handle or brass
ttings 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 and may
cause failure of the support structures.
15. To prevent severe burns, always allow the milk or colostrum to cool
completely before handling or feeding to calves.
16. The Pasteurizermustbeelectricallygrounded. DO NOT modify the
plug that is provided with thePasteurizer; ifitwill nottthe outlet,
have an electrician install a proper electrical outlet.
17. The pasteurizer must be installed on a level surface to evenly

Receiving Your Pasteurizer
Use care when unpacking your Combi 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. For COMBI 10G Models, save the bottom half of
the powder coated shipping container for use as a pasteurizer stand
INSTALLATION:
Preparing the Machine
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.
Unpacking the COMBI 60G
Mounting the Control Panel
The pasteurizing unit is typically shipped with the control box
detached and packed in the tank of the unit. Mounting of the
control box will be required. Gently remove the controller from the
milk pot. Four mounting holes are provided on the top surface of
the unit. Using the bolts that are provided, attach the control unit in
an upright fashion to the top lid of the pasteurizer. The screw slots
may allow some adjustment of the propeller and shaft if required
later. The electrical connections are already made. Use care to not
stretch these connections. See the next gure for the COMBI 10G
and COMBI 30G.
Here is another image shown below of the COMBI 60G which has
side mounting screws to secure the control box to the top of the
cabinet.

Combi Pasteurizer Owner Manual | 10G, 30G & 60Grev092015
Mounting the COMBI 10G onto the Base
The COMBI 30G and COMBI 60G each come with a fully assembled
leg stand to support the machines. The COMBI 10G is shipped to
you in specially designed box that is half metal and half cardboard.
You can discard the top cardboard half after removing straps and
carefully lifting oof the machine. With an assistant, carefully lift the
pasteurizer out of the metal powder coated box and set the COMBI
10G to the side. Turn the white box over and move it to the location
where you wish to install the machine. Lift the pasteurizer and place
it on the box so that the sides and front line up with the mounting
holes. You will nd two mounting brackets and hardware which you
can use to secure the COMBI 10G cabinet to the support box. Refer
to the illustration below.
Connecting the Stirring Shaft
The motor shaft must also be attached by inserting it through the
side entry of the coupler, followed by right-hand threading of the
shaft into the coupler. The shaft can be gripped at the knurling
located midway on the shaft. Only nger tighten as shown in the
next image.
Dairy Tech recommends that the stirring shaft be removed from the
coupler any time the pasteurizer is being moved. This will help to
avoid a bend in the shaft. A bent shaft can result in premature failure
of the drive motor. Treat the shaft with due care any time it is not in
the machine.
Lid Storage
The lid is packaged with the unit and can be hung on either side of
the pasteurizer by the 2 holes at the top of the tab. This provides a
convenient place to store the lid while the unit is being cleaned or
lled. See below for proper lid storage.

Connecting the Milk Spigot
Combi Pasteurizers come supplied with the highest quality 304SS
buttery drain valve. These are installed on the front ange of the
tank drain much the same as connections are made to a bulk tank
ange using the clamps provided. Please see the diagram below.
Make certain to include the gasket between each tting. These parts
can then be easily removed for thorough cleaning in a sink. See next
image.
Choosing and Preparing a Location
Criteria for Selecting a Location
a) Choose an indoor spot that will be protected from the
elements. Extreme heat will allow milk spoilage and freezing
temperatures will damage the unit.
b) Cold water is required to be connected to the unit for water
cooling the milk or colostrum, and a nearby hot water source
is necessary for proper cleaning.
c) Floor drains will allow for proper cleaning and rinsing of the
product as well as to clean up milk spills.
d) Power requirements are 240vac 30 or 50 amp circuit breaker
rated for use as branch circuit protection. All 3 Models
can also be ordered for 3 phase electric supplies. See local
voltages for correct connection requirements.
e) Floor space requirements are approx. 1 yd²(1M²)
f) Avoiding extremely drafty areas will improve heating
eciency of the unit.
g) Always have 2 people lift and carry the unit grasping with
both hands on the sides of the unit. The supports of the legs
can be used for lifting. Never attempt to move the unit while
it is full of milk or water.
Connecting the Hoses for Water-Cooling
WATER-COOLED UNITS: A 6’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 nished. 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. Pressure reduction is provided by the orice of the solenoid
valve. A relief valve is incorporated into the design of the COMBI 30G
and COMBI 10G with a port coming out of the bottom of the unit
toward the right rear. The COMBI 60G Model contains dual pressure
relief ports. Should the drain line be raised too high or blocked,
pressure will relieve itself by opening this valve which will spill water
onto the oor. This protects the metal milk tanks from implosion
in high pressure situations. Take care to avoid situations where any
back pressure exists on the drain line, this will void the warranty.
WATER DRAIN: This 4’black hose is connected internally and takes
cold water out of the unit once it has absorbed heat during the
cooling cycle. 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
cause damage to the cooling jacket and void the 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. This prevents any back pressure to the
unit.
It is important to keep water turned on anytime the pasteurizer is in
operation to prevent damage to the heating elements.
