INSTALLATION
INSPECTION
All Univex mixers are inspected and tested at the factory, however, they should be inspected carefully by
the person making the installation for loose, damaged or broken parts. Detached parts and fixtures should be
checked against the packing list to determine that all are present. Any damages, imperfections or shortages
should be reported to the dealer or Univex and the shipping carrier.
WARNING: After the mixer has been inspected, wash the mixer, mixing bowl and attachments with warm
water and mild soap. For safety, follow the cleaning instructions on page10.
INSTALLATION
Selecting the best location for your Univex mixer will depend on the lay-out of your kitchen. Locate
your mixer where it will save steps for the operator and be sure to provide sufficient clearance around it for
ease of maintenance and cleaning, as well as for the efficient and safe use of the mixer.
The mixer should be operated on a sturdy bench or table with the height determined to suit the operator.
IMPORTANT ELECTRICAL SERVICE INFORMATION
Electrical wiring instructions are found in the wiring diagram (Figure 2) on page 12. Before making
electrical connections, CHECK the specifications on the nameplate to make sure that they agree with the
available electrical service. A grounding type three terminal plug is provided for safety. If you do not have a
mating receptacle, have a qualified electrician provide one with grounding provisions in accordance with
local safety codes.
SWING RING™SAFETY GUARD
Your SRM8 mixer features a Swing Ring™ Safety Guard that conveniently swings out of the
way to place or sample ingredients in the bowl. It also provides a clear view of the product throughout
the mixing cycle.
This mixer will not operate unless the Swing Ring™Safety Guard is properly engaged.
The guard activates a safety switch that enables the mixer to operate only when the guard is closed. This
switch protects against accidental operation of the mixer when the guard is open. The mixer will auto-
matically stop if the guard is opened. An additional switch in the bowl lift automatically stops the mixer
if the bowl is lowered from the “up” (mixing) position.
To open the guard for access to the bowl, first turn the mixer off by pushing the red “Stop” push-
button (Figure 1 [7]) and swing the guard up. Close the guard and press the green “Start” push-button
(Figure 1[6]) to resume mixing operations.

OPERATING THE SRM8 MIXER
Your SRM8 mixer is designed to meet the cook’s demand for an efficient, dependable and
powerful 8 quart countertop mixer. It will give unfailing performance over a period of years when
operated and maintained according to the instructions contained within this manual.
This mixer drives various agitator attachments through the beater head shaft, which are used to beat,
mix, or whip liquid, viscous or dry ingredients. A rugged and powerful 1/2 horsepower motor powers the
mixer. The speed of the beater head shaft can be varied from approximately 85 to 350 revolutions per
minute.
WARNING: Never put hands, spoons, utensils or other objects into the bowl while the mixer is operating.
Note: Noise emissions are below 70db.
SECURING THE BOWL AND INSTALLING THE MIXER AGITATORS
Place the bowl on the bowl support (Figure 1 [13]). Align the holes in the bowl mounting brackets over
the pins on the bowl support (Figure 1 [14]) and lower the bowl into position.
With the bowl in the down position, the bowl lift handle (Figure 1 [3]) will be in the vertical position.
With the bowl in the down position, install the desired agitator by sliding it upward onto the beater head
shaft (Figure 1 [1]) . Rotate the agitator counter-clockwise until it drops into place on the beater head shaft
pin.
WARNING: Serious injury may result if the bowl is not fully secured to the bowl support using the bowl
support pins.
With the bowl secured, add ingredients. Liquids should be added first. The bowl is now ready to be
raised to the “up”(mixing) Position by turning the bowl lift handle (Figure 1 [3]) counter-clockwise to
the horizontal position.
Note: Exceeding the mixer capacity (page 7) can cause damage to the mixer and will void the factory
warranty.
When using the wire whip agitator, raise the bowl to the “up” position first and then add ingredients to
avoid wire whip damage.
Close and secure the Swing Ring™ Safety Guard before proceeding.
USING THE BOWL LIFT
The mixer will not operate unless the bowl is in the up position. Raise the bowl by turning the bowl lift
handle (Figure 1 [3]) counter-clockwise until it locks into place. To lower the bowl, turn the handle clock-
wise. It is necessary to lower the bowl to change the agitator. This also makes the bowl accessible for filling.
WARNING: Do not shut off the mixer by lowering the bowl. Use the red “Stop” push-button.
Page 5

START/STOP CONTROLS
This mixer will start only when the Swing Ring™ Safety Guard is closed and the bowl is in the raised
position. (If the optional timer is installed, the timer must be set) . To start the mixer, push the Green
“Start” push-button (Figure 1 [6]). For safety and operator ease, this mixer is equipped with an over-
sized, red mushroom style stop button (Figure 1 [7]).
NOTE: Although the motor shuts off instantly when the Swing Ring™ Safety Guard is opened, or the
bowl is lowered, or the stop button is pushed, the agitator may NOT come to a complete stop for several
revolutions. DO NOT PUT HANDS OR UTENSILS INTO THE BOWL OR NEAR THE BEATER
HEAD SHAFT UNTIL IT HAS FULLY STOPPED.
Both the Start and Stop push-buttons are momentary contact type buttons. They prevent accidental start-
up in the event of power interruption.
SETTING THE TIMER (if provided)
When the mixer is equipped with a timer, the mixer will not operate unless the timer has been set or
placed in the “HOLD” position. To start the mixer, first turn the timer (Figure 1 [5]) to the desired
mixing time. Then push the green “Start” push-button (Figure 1 [6]). The mixer will automatically stop
when the timer has reached “0”. To stop the mixer before the timer has reached “0”, push the red “Stop”
push-button (Figure 1 [7]).
The timer may be set for up to 15 minutes or may be set to the “HOLD” position for continuous
operation. When setting a time of less than 5 minutes, turn the timer beyond 5 minutes and then return it
to the desired time.
NOTE: The mixer will start only when the Swing Ring™ Safety Guard is closed and the bowl is in the
raised position. Do not operate the mixer without the bowl in place.
SPEED CONTROL
One major advantage to using a Univex planetary mixer is the ability to change speeds while the mixer
is running. To change speeds, turn the speed control knob (Figure 1 [4]) to the desired speed. The speed
control is labeled from high to low with infinite settings in-between which gives the operator tremendous
flexibility.
Use low speed for heavy mixtures such as pizza, bread or roll dough. For most mixing tasks, start on low
speed and progress to a higher speed as needed. Use high speeds for whipping cream, beating eggs, and thin
batter.
WARNING: To avoid damaging your mixer, follow the speed, volume limits and attachment recommenda-
tions shown on the mixer capacity chart on page 7.
If the mixer jams and the motor stalls, immediately press the stop button. Take the necessary steps to
reduce the load. Never put your hands in the bowl to clear a jam!

MIXER CAPACITY CHART AND RECOMMENDED AGITATORS
SRM8 PLANETARY MIXER CAPACITY CHART
Dough capacity based on 70ºF water and 12% flour moisture
NOTES: Recommended speeds are for the capacities listed.
Dough capacity, for bread, rolls, pizza, bagels or doughnut, is based on a 12% flour moisture
and 70˚F (21˚C) water temperature. Reduce capacity by 10% if water below 65˚F. is used.
If higher gluten flour is used, reduce total capacity by 10%.
AR% (Absorption Ratio) = the weight of the water divided by the weight of the flour.
The lower the AR% the stiffer and more difficult the dough is to mix.
An AR% below 40% will reduce the total capacity.
1 Gallon of water = 8.3 lb. (1 liter of water = 2.2lb.)
The speed at which the mixer is operated at can also affect the mixer’s capacity. Always follow the
recommended mix speed found on the mixer capacity chart. Certain tough dough, such as thin pizza dough,
should have a mix time no longer than 5 minutes on low speed.

DOUGH ABSORPTION RATIO
ABSORPTION RATIO
The absorption ratio is an important factor in the dough capacity of a mixer. it indicates the relative
wetness of a batch of dough. It is the ratio of the weight of the water and other liquids to the weight of the
flour and other dry ingredients, shown as a percentage.
% Absorption Ratio (%AR) = Weight of water (8.33 lbs. per gallon) divided by the weight of the flour x 100%
When mixing any dough with an absorption ratio lower than the one listed, you must decrease the size
of the batch proportionately. To calculate the maximum capacity at your absorption ratio:
1. Divide the absorption ratio of the batch to be mixed by the absorption ratio listed in the mixer
capacity chart on page 7.
Example: The rated capacity for a SRM8kneading pizza dough with a 50% AR is 4 lbs.
your dough has an AR of 45%
45% divided by 50% = 90%
2. Multiply the rated batch size by the percentage found in step 1. The result is the maximum batch size.
Example: Maximum rated batch size of 4 lbs. multiplied by 90% = 3.6 lbs maximum capacity.

CLEANING AND PREVENTIVE MAINTENANCE
CLEANING YOUR MIXER
Consistent use of the following procedures will ensure that your mixer is in optimum operating condition.
•Disconnect the electrical power supply cord before cleaning.
• Wash the body of the mixer, the bowl support, and beater head shaft with warm water and mild soap.
• Do not rinse with a hose.
• Do not use abrasive pads to wash the mixer.
• Dry the mixer thoroughly using a soft cloth.
• Wash the bowl and agitator immediately after each use. If egg mixtures or flour batter have been used,
rinse the bowl and agitator with cold water before washing with hot water.
• Dry bowls and agitators thoroughly.
OPERATOR’S PREVENTIVE MAINTENANCE
For best long-term performance, operators should follow these simple practices.
• Lightly lubricate the beater head shaft (Figure 1 [1]) after washing with a food grade lubricant.
• Do not cover the mixer with a plastic bag, as this traps humidity inside the mixer.
• If the electrical power supply cord has become damaged, it must be replaced by an approved cord or
assembly available from Univex directly or from a Univex service agent.
• Do not over load the mixer. Over loading is the #1 cause of mixer failure. Follow the table of mixer
capacity on page 7. It may be helpful to post a copy of the chart near the mixer.
• Keep the mixer properly lubricated. Lack of lubrication is the #2 cause of mixer failure. Key
mixer components require lubrication after each 500 hour of operation.
