3.1 UNCRATING
Cut and remove the outer packaging. Cut the (4) four clamps that hold the refrigerator
to the skid lift the unit off the skid. If machine was laid down during this operation leave
the cabinet up right for 24 hours before plugging into power source. To install draft
arm, rst place rubber washer over draft arm mounting holes in cabinet top and put
beer line connector down through hole. Next secure draft arm with four bolts provided.
To retain complete mobility of the cooler, the accessory CO2 tank (up to ve pounds in
size) must be placed inside the cabinet.
3.2 SEALING
WHEN SANITATION CODES REQUIRE SEALING TO FLOOR, THIS METHOD MAY
BE USED
1. Tip cabinet and apply a bead of silicone seal on bottom edge of the base.
2. Return cabinet to upright position and using proper equipment, lift cabinet into location.
Heavy appliances should not be used on the same circuit with the cooler.
CAUTION: If an extension cord is necessary, use only a three wire grounding type of
wire, size 16 AWG or heavier; do not exceed 20 feet in length. The use of ungrounded
cords or overloaded circuit voids compressor warranty.
3.3 CLEANING OF CABINET
The exterior of the cabinet is either black vinyl or stainless steel and should be cleaned
only with lukewarm water, taking care not to scratch the surface. Mild detergents are
also recommended. The interior can be cleaned in a similar manner. THE CONDENSER
MUST BE CLEANED AT REGULAR INTERVALS. FAILURE TO DO SO CAN CAUSE
COMPRESSOR MALFUNCTION AND WILL VOID WARRANTY.
Clean approximately every six months, depending upon usage, dust, etc. Pull cabinet
away from wall and thoroughly vacuum the condenser and surrounding surfaces.

3.4 LOCATION
Units represented in this manual are intended for indoor use only. Be sure the location
chosen has a oor strong enough to support the total weight of the unit and contents.
For the most efcient operation, be sure to provide good air circulation inside and
outside of the unit.
NOTICE: This cooler is designed to maintain your beer temperature within the most
desirable range of 32° to 38°F. You can expect this temperature with the proper
temperature control setting and in a normal environment. It is important to understand
that when the beer is purchased, it must be installed inside the cooler as soon as
possible to avoid excessive warm-up of the beer. If this happens, it may take many
hours for the temperature to be reduced to the desirable range. No provision is made
for rapid cooling of beer which has become too warm.
INSIDE CABINET
The rst cleaning must be made when you unpack the unit and before switching it on.
Clean it with water and a mild detergent.
OUTSIDE CABINET
Be sure the unit has good air circulation in front. Avoid hot corners and locations near
stoves and ovens. The place where the refrigerator is placed must be open and free of
dust and debris.

3.5 TAPPING INSTRUCTIONS
The largest keg this cooler accepts is a half keg. The Sankey type is the most modern
and easiest of all to tap with the available taps. The type of keg and tap you use
will depend on the brand of beer your purchase. Your beer distributor can provide
additional instructions and tips on how to maintain the beer to your satisfaction.
Following these tapping instructions, place the keg in front of cabinet for tapping. After
all connections are complete and checked for leaks, place the CO2 bottle in the rear
(inside) of cabinet with the pressure gage visible for reading, then place the keg in
position, allowing the door to be closed completely without interference. Make certain
that beer line and keg are not touching the evaporator.
HOW TO TAP A KEG OF BEER (SANKEY-TYPE)
1. Connect line from pressure source to gas nipple (use clamp). Using coupling
washer connect beer line to thread on probe. Holding ats on probe with wrench
tighten wing nut or hex nut on beer hose.
2. Align tap with lugs in barrel, insert tap.
3. Turn tap body handle ¼ turn clock wise until tight to secure tap to barrel. Turn on

3.8 SHELVING INSTALLATION
1. Hook shelf rails onto shelf pilasters
2. Position all two shelf rails equal in distance from the oor for level shelves.
3. Wire shelves are oriented so that cross support bars are facing down.
4. Place shelves on shelf clips making sure all corners are seated properly.
4 // OPERATIONS
4.1 MECHANICAL (ANALOG) TEMPERATURE CONTROL
Before you connect the unit to the power supply, verify the thermostat is NOT in the OFF
position (the position of the thermostat must be different than zero). If the thermostat
is in the OFF position, the compressor will not run. Keep in mind, the evaporator fan
and lights will still have power while the thermostat is in the OFF position.
The knob of the thermostat is the temperature controller. This is located inside the
cabinet. Please be sure that the knob of thermostat is pointing to the yellow arrow
(Figure #3). This position is recommended by the factory to assure correct function of
the equipment (see Figure #1 below).
NOTE: Keep in mind, if you move the knob to a different position than the
position recommended from factory, the temperature will change, as well.
The knob position near the number one, gives you the warmest temperature and the
knob position near the number seven, gives you the coldest temperature.

5 // MAINTENANCE
5.1 STAINLESS STEEL CARE AND CLEANING
Proper cleaning of stainless steel requires soft cloths; never use steel pads, wire
brushes or scrapers!
Cleaning solutions need to be alkaline or non-chloride cleaners. Any cleaner containing
chlorides will damage the protective lm of the stainless steel. Chlorides are also
commonly found in hard water, salts, household and industrial cleaners. If cleaner
containing chlorides is used be sure to rinse repeatedly and dry thoroughly upon
completion.
Routine cleaning of stainless steel can be done with soap and water. Extreme stains
or grease should be cleaned with a non-abrasive cleaner and plastic scrub pad. There
are also stainless steel cleaners available which can restore and preserve the nish of
the steel's protective layer.
Never use an acid based cleaning solution! Many food products have an acidic content
which can deteriorate the nish. Be sure to clean ALL food products from any stainless
steels surface. Common items include peppers, tomatoes and other vegetables.
5.2 CLEANING THE CONDENSER COIL
DANGER: Power must be turned off and disconnected from the power source
whenever performing maintenance, repair or cleaning the condensing unit.
Disconnect unit from power supply. Remove front bottom panel and carefully slide out
the condensing unit. The condenser coil requires regular cleaning; recommended is
every 30 – 60 days, depending on the accumulation of dust and grease.
If the buildup on the coil consists of only light dust and debris the condenser coil can
be cleaned with a simple brush. Heavier dust build up may require a vacuum or even
compressed air to blow though the condenser coil.
If heavy grease is present there are de-greasing agents available for refrigeration
use and specically for the condenser coils. The condenser coil may require a spray
with the de-greasing agent and then blown through with compressed air. Be sure all
electrical and mechanical parts are dry before turning on the power. Never use a high
pressure water wash for this cleaning procedure as water can damage the electrical
components located near or at the condenser coil! Do not place lter material in front
of condenser coil. This material blocks air-ow to the coil similar to having a dirty coil!
12
// www.micromatic.com
If you keep the condenser clean you will minimize your service expense and lower
your electrical costs. Failure to maintain a clean condenser coil can initially cause high
temperatures and excessive run times. Continuous operation with dirty or clogged
condenser coils can result in compressor failures.
Neglecting the condenser coil cleaning procedures WILL VOID YOUR WARRANTY
associated with the compressor or cost to replace the compressor!
To put back the condensing unit in its place, slide in the unit carefully. BE SURE
DRAIN PIPE IS LOCATED OVER THE PAN. Replace front bottom panel.
5.3 DRAIN MAINTENANCE
Each unit has a drain located inside the unit which removes the condensation from
the evaporator coil and evaporates it at an external condensate evaporator pan. Each
drain can become loose or disconnected from moving or bumping the drain. IF YOU
NOTICE EXCESSIVE WATER ACCUMULATION ON THE INSIDE OF THE UNIT
be sure the drain tube is connected from the evaporator housing to the condensate
evaporator drain pan.
IF WATER IS COLLECTED UNDERNEATH THE UNIT you may want to check the
condensate evaporator drain tube to be sure it is still located inside the drain pan. The
leveling of the unit is important as the units are designed to drain properly when on a
level surface, if your oor is not level this can also cause drain problems. Be sure all
drain lines are free of obstructions; typically food products are found blocking drain
lines causing water to back up and overow the drain pan.

5.4 PROCEDURE TO INSTALL THE AIR CHANNELS AND DRAFT TOWERS
(ONLY “DD” MODELS)
MODELS: MDD23-E, MDD58-E, MDD68-E, MDD78-E & MDD94-E
This procedure describes how to install the air channel needed to provide cold air
directly into the beer towers.
TOOLS NEEDED: Philips screwdriver
STEP 1 Locate the gaskets and bolts included in with your Tower. Place gasket
over the pre-drilled holes and place the 4 screws thru the tower base.
