Installation, Use & Maintenance Guide
Wine On Tap
Keg wine is the smart choice. Fine varietal wines are now in kegs. Serve wine at
the optimal temperature the vintner intended it to be enjoyed. Pro-Line Wine
units feature dedicated dual-temperature zones: one for whites (45°F) and one
for reds (55°F). Keg wine is a great value with minimal waste and stays fresh
until poured.

Receiving & Inspecting
Upon receiving your new Micro Matic Pro-Line Wine dispenser, check the package
and the unit for any damages that may have occurred during transportation.
Visually inspect the exterior of the package. If damaged, open and inspect the
contents with the carrier. Any damage should be noted and reported on the
delivering carrier’s receipt.
In the event that the packaging is not damaged, yet upon opening, there is
concealed damage to the equipment notify the carrier immediately. Noti cation
should be made verbally as well as in written form. Request an inspection by the
shipping company of the damaged equipment. Retain all crating material until
inspection has been made. Finally, contact Micro Matic.
Uncrating
Pro-Line Wine
1. Cut and remove the outer packaging.
2. Lift the unit o the skid.
3. If the unit has been laid down during this operation leave upright for 24 hours
before plugging into power source.

Location
• Be sure the location chosen has a oor strong enough to support the total weight of the
unit and contents.
• Recommended to use a professional installation company.
• For the most effi cient operation, be sure to provide good air circulation around the unit.
• MDD23W cannot be used for built-in applications.
• Avoid hot corners and locations near stoves and ovens.
• It is recommended the unit be installed no closer than 2" from any wall.
• The place for the dispenser must be open and free of dust and debris.
Installation
Install Wine Font (Sold Separately)
• Place rubber washer over draft tower mounting holes in cabinet top.
• Place wine line down through holes.
• Secure font with four bolts provided.
• Attach keg connectors to wine lines (provided with wine font).
Install Keg Tapping Kit(s) (Sold Separately)
Use only Wine Certi ed components for wine dispensing. This includes grade 304 stainless steel
or better and Barriermaster Flavourlock tubing. Use of these components assures vintners quality.
Use John Guest swivel elbows to minimize line kinking. Use zip ties to secure to gas line (blue
hose) to John Guest tting.

Keg Temperature: Storage & Serving
Storage
It is important to understand that when the keg of wine is delivered it must be properly stored.
• White wine must be stored inside the cooler as soon as possible, as it may take as many
as 24 hours for the temperature to be reduced to the desirable range.
• It is recommended to store both reds and whites at room temperature (approximately
72°F.)
• Wine kegs stored in a walk-in cooler (approximately 38°F) may dramatically eect the
time it takes to reach the desired serving temperatures.
• Allow 24 hours for kegs to reach the desired serving temperature (45°F for whites and
55°F for reds).
• Just like a bottle of wine, the best temperature to store white or red wines is between
45-60°F: neither too cold, nor too warm. Remember, wines are both cold- and heatstabilized. Most white wines are cold-stabilized to approximately 36°F. If the wine gets
any colder for any length of time, the risk arises that the naturally occurring “tartrates”
may drop out of solution and appear as “sediment” in the bottom of a wine glass.
Serving
Pro-Line Wine units are designed to maintain your wine keg temperature within the vintners
recommended temperature serving range:
• White wines: 45°F (range: 40-45°F)
• Red wines: 55°F (range: 55-60°F)
IMPORTANT NOTICE:
The thermostats on the Pro-Line Wine units have been factory preset at approximately
45°F for white wine dispensing and approximately 55°F for red wine dispensing.
Any change to the factory settings will aect performance of unit and void the warranty.
Factory testing has produced results that show consistent wine (liquid) temperatures are being
maintained by the unit. The Pro-Line Wine unit operates like any refrigeration unit; the compressor
is engaged when the interior air temperature reaches the pre-determined maximum level, cooling
the unit until it reaches the pre-determined minimum level. The goal is consistent wine (liquid)
temperature inside the keg. Thermostat displays are reading the air temperature setting and may be
dramatically dierent than the keg (liquid) temperatures. To verify, measure the temperature of the
wine dispensed in the glass.
