    CAUTION
    The cutout dimensions shown above are based on a 25 (64.3 cm) deep counter top. Your counter top may be different than this and require other front to back dimen-sioning. Refer to the product dimensions when determining the required dimensions.

  4. If you are installing your keg refrigerator under a counter you will need to drill 5 holes in the counter top to mount the tower. The first hole is a 1″ diameter hole located at the center of the tower for the beer line, lo- cate approximately 13″ (34.3 cm) from the front edge of the counter top (based on a counter top depth of 25%”). Next drill the 4 tower mounting holes per the di- mensions. The hole diameter is dependent on the counter top material and if screw anchors are required. The screws supplied are in the literature pack and are a #10 x 1″ type AB stainless steel screw. Mark and cut the rectangular cutout for the drain sump. After the holes are drilled and the keg refrigerator is in place under the counter top feed the beer line through the tower gasket, the 1″ hole in the counter top and the hole in the top of the keg refrigerator. Mount the tower to the counter top with the 4 screws provided. Place the counter top drain sump, from the literature pack, in the rectangular hole with the radius cutout to the rear around the tower and place the grate in the sump

  5. Mount the regulator to the COz tank (connection) Note that the regulator has left hand threads and has tobe turned counterclockwise to tighten. Tighten with the adjustable wrench or the 1″ open end wrench.

  6. Connect the red air line(s) from the regulator to the large air line fitting on the keg coupler with a large hose clamp (connection).

  7. Connect the clear beer line from the tower to the small air line fitting on the keg coupler with a small hose clamp (connection).

  8. Locate the COz tank in the corner of the refrigerator and secure with the chain. Close the faucet handle on the tower.

  9. Hooking up the keg coupler to the keg: Verify the coupler is in the “OFF” position.Align the lugs on the keg with the corresponding openings on the keg coupler and turn clockwise until the coupler stops (about 90°). Push down and twist the top of the coupler clockwise to allow gas to enter the keg.MARVEL-MOKR224-24-in-Outdoor-Mobile-Dispenser-for-Beer-fig 13

Optional CO2 tank external mounting bracket:

  • The optional mounting bracket is designed to hold the 5# CO2cylinder that comes with the beer dispenser. Larger cylinders may be purchased froma third party and mounted extenally. Use the hole port on the rear of the cabinet to run the CO2 line to the keg.
  • Many options are available for mounting the CO2 tank outside of the beer dispenser to gain additional cold storage space inside.
  • Secure the optional external mounting bracket on the back of the beer dispenser (this is ideal for mobile units) or mount within adjacent cabinetry (ideal for undercounter built-in units:
  • Mount the (4) screws (#10-32 x A” flathead machine screws) provided with the bracket in the rear of the appliance. Do not completely tighten. Place the key slots in the flanges of the bracket over the four screws and tighten them to secure the bracket to the back of the cabinet.

Background

Stainless steel does not stain, corrode, or rust as easily as ordinary steel, but it is not stain or corrosion proof. Stain-less steels can discolor or corrode if not maintained prop-erly.
Stainless steels differ from ordinary carbon steels by the amount of chromium present. It is this chromium that provides an invisible protective film on the surface called chrome-oxide. This protective chrome-oxide film on the surface can be damaged or contaminated, which may result in discoloration, staining, or corrosion of the base metal.

Care & Cleaning

  • Routine cleaning of the stainless steel surfaces will serve to greatly extend the life of your product by removing contami-nants. This is especially important in coastal areas which can expose the stainless to severe contaminants such as
  • It is strongly recommended to periodically inspect and thor-oughly clean crevices, weld points, under gaskets, rivets, bolt heads, and any locations where small amounts of liquid could collect, become stagnant, and concentrate contami-nates. Additionally, any mounting hardware that is showing signs of corrosion should be replaced.
  • Frequency of cleaning will depend upon the installation location, environmental, and usage conditions.

Choosing a Cleaning Product

The choice of a proper cleaning product is ultimately that of the consumer, and there are many products from which to choose. Depending upon the type of cleaning and the degree of contamination, some products are better than others.

Typically the most effective and efficient means for routine cleaning of most stainless steel products is to give the sur- faces a brisk rubbing with a soft cloth soaked in warm water and a gentle detergent, or mild mixture of ammonia. Rub- bing should, to the extent possible, follow the polish lines of the steel, and always insure thorough rinsing after cleaning. Although some products are called “stainless steel clean- ers,” some may contain abrasives which could scratch the surface, (compromising the protective chrome-oxide film), and some many contain chlorine bleach which will dull, tarnish or discolor the surface if not completely removed. After the stainless surfaces have been thoroughly cleaned, a good quality car wax may be applied to help maintain the finish.

NOTE

Stainless steel products should never be installed, or stored in close proximity to chlorine chemicals. Whichever cleaning product you chose, it should be used in strict accordance with the instructions of the cleaner manufacturer

The following suggestions will minimize the cost of operating your refrigeration appliance.

  1. Do not install your appliance next to a hot appliance (cooker, dishwasher, etc.), heating air duct, or other heat sources.
  2. Install product out of direct sunlight.
  3. Ensure the front grille vents at front of appliance be-neath door are not obstructed and kept clean to allow ventilation for the refrigeration system to expel heat.
  4. Plug your appliance into a dedicated power circuit. (Not shared with other appliances).
  5. When initially loading your new product, or whenever large quantities of warm contents are placed within refrigerated storage compartment, minimize door openings for the next 12 hours to allow contents to pull down to compartment set temperature.
  6. Maintaining a relatively full storage compartment will require less appliance run time than an empty compart-ment.
  7. Ensure door closing is not obstructed by contents stored in your appliance.
  8. Allow hot items to reach room temperature before plac-ing in product.
  9. Minimize door openings and duration of door openings.
  10. Use the warmest temperature control set temperature that meets your personal preference and provides the proper storage for your stored contents.
  11. When on vacation or away from home for extended pe- riods, set the appliance to warmest acceptable tem- perature for the stored contents.
  12. Set the control to the “off” position if cleaning the appliance requires the door to be open for an extended period of time.
  13. For wine storage products:

When serving temperatures are not required, return the compartment(s) set temperature to the ideal red and white wine long term storage temperature of 13°C / 55°F.
