Product Information

Beverage Dispensers

The Beverage Dispensers are available in various models including Mini, Standard, Heated, Whipper, and Super Bowl. They are manufactured by Grindmaster CorporationTM and are designed for serving beverages. The dispensers come with a service manual that provides detailed instructions for unpacking, installation, assembly, disassembly, routine maintenance, helpful hints, preventative maintenance, and security kit installation.

Unpacking

When unpacking the dispenser, you will find it packed in two cartons: the base pack and the bowl pack. Start by opening the bottom flaps of the base pack. Make sure not to leave the base upside down as it can damage the refrigeration system. Check that all four rubber feet are attached to the legs after removing from the base pad. If any feet are missing, replace them on the legs. Instead of lifting from the louvres/ventilation slots, place your fingers under the base plate.

Installation

1. Roll the chassis upside down.
2. Open the bottom flaps of the carton and fold them back.
3. Hold the flaps out of the way and roll the carton over.
4. Lift off the carton and remove the bottom pad.
5. Place the base on the counter.
6. For heated units (HD15/WHD15), install Safety Arms using a Phillips Head Screwdriver:
7. Place the unit on its side to access the bottom of the unit.
8. Line up the arm holes with the holes on the bottom of the unit.
9. Insert the arms into the holes and lock them in place.

Assembly

1. Place the bearing sleeve on the guide pin, ensuring that the flat sides of the pin and sleeve line up. The sleeve should slide down over the guide pin and rest on the cooling plate.

2. Put the impeller over the bearing sleeve with the fin side up.

3. Turn the bowl upside down and place the bowl gasket over the neck of the bowl. Moisten the gasket with water. Note: On D112 units, place the bowl gasket around the cooling dome.

4. Place the pump cover over the guide pin with the spray tube toward the front. The tab on the front of the pump cover should fit between the two locator buttons on the bowl. For Mini units, ensure that the bent part of the spray tube faces the front of the bowl.
   Note: Use the agitator cover instead of the pump cover and spray tube for fresh juice, drinks that foam (iced tea or dairy products), or heavy viscous drinks.

5. Install the lockdown washer or clamps to lock everything into place. Lock down two clamps closest to the front of the bowl first.

IMPORTANT : Never pour dry powder, crystals, or concentrate into a dry bowl. Premixing beverage in separate container is recommended. If mixing in bowl, always add water first.

ROUTINE MAINTENANCE

For all Models

Cleaning Your Dispenser
To optimize performance or when using dairy products, clean unit daily.
Regular cleaning of bowl components will result in maximum pumping efficiency, proper seating and sealing, and prevention of leaks at the valve O-Ring and bowl gasket by removing dried-on beverage solids and pulp from mov-ing sealed parts.

1. Wash all bowl components regularly. Follow all local health codes.
   • efer to Disassembly, Cleaning, and Assembly instructions on.

Sanitizing Your Dispenser
Refer to Disassembly and Assembly instructions on.

1. In the bowl, mix one gallon of Oxford Chemical’s Disinfectant/Sanitizer Formula C or its equivalent.
2. Turn on spray motor(s) and allow sanitizer to spray around inside of bowl for a period of time as recommended by the sanitizer manufacturer. Formula C is satisfactory for this purpose when mixed in a solution of 1 liquid ounce of cleaner to 4 gallons of water. Run spray motor(s) for 60 seconds. In areas with extreme hard water, consult the local health authority.
3. Drain sanitizer completely and thoroughly during each step of the cleaning process (wash, rinse, and sanitize). Refer to tips on draining in Disassembly Guide on page 3.

HELPFUL HINTS

1. Noisy Impeller: Do not run impeller dry. The impeller will make a chattering sound in an empty bowl. Remove the impeller and run a small amount of water in the bowl.

2. Valve and O-Ring: On the first installation, if there is an after-drip, place your hand on the valve and with a slight downward pressure turn it slightly. This will help seat the o-ring so that it is properly aligned
   with the valve seat. If an o-ring becomes cut or worn it should be replaced. If you are pumping
   a product which has excessive pulp, a separate valve weight may be purchased to add extra
   weight so the o-ring will press down against the pulp and guarantee a positive shut-off. VALVE CAP

3. Valve Cap Use: The Valve Cap (Part # 2039) insures that a tight valve seal will occur with products containing heavy pulp. The Valve Cap can be installed by placing it on top of the Valve after the Valve has been assembled into the bowl. See Figure E.

4. High Water Marks on Bowl: When you agitate, you may get “high water marks” as the beverage level drops. Keep the bowl as full as possible. Frosted bowls are available which are helpful in reducing the appearance of water marks.

5. To Spray or Not to Spray: Most beverages can be sprayed. It is best not to spray iced tea, iced coffee, natural juices, or beverages that foam (whipped drinks). A special agitator plate is used in place of a pump cover and spray tube to promote circulation.

6. Proper Cooling: Always keep spray switch on when refrigeration switch is on. A unit must spray or agitate to cool. Failure to do this will cause impeller to lock-up. The dispenser is designed to run 24 hours a day. Keep both spray and agitate on when beverage is in the bowls.

7. Condensation: Condensation on the bowls and lids is natural, cool, and refreshing. The amount of condensation is affected by humidity. Condensation will run down the front panel into the drip tray. Remember to occasionally empty the drip trays.

8. Single Bowl Operation: If you find it necessary to run your dispenser with only one bowl containing beverage, put one half (1/2) cup of water in the unused cooling plate depression(s) for best one-bowl operation and efficiency.

PREVENTATIVE MAINTENANCE

1. Wash all bowl components regularly.

2. Wash impeller and bearing sleeve individually and check for wear.

   • a) Check for wear on bearing sleeve (flange should be 1.77mm thick – thickness of penny or quarter). (Figure B)

   • b) Check for wear on impeller (inner white center section
     should be flush with colored part of impeller). (Figure A)

   • c) If bearing sleeve or impeller do not spin freely or are worn replace them. (Figure E)

   • d) Worn parts can cause personal injury, impair cooling and can damage machine. (Figure C & D)

3. Check valve o-rings and bowl gaskets for wear or damage – replace every 6 months or as needed.

4. Every 6 months or more often if needed: unplug unit, remove panels, clean condenser and interior. (Remove dust and lint from fins with a soft brush and vacuum.)

MAGNETIC LOCK

Magnetic Lock Problems

If a unit is not spraying, check the following:

• a) The impeller must spin freely when the bearing sleeve is held between the thumb and the forefinger,
• b) The impeller should turn when assembled and the motor switch is turned “ON”.
• c) The pump motor runs without the impeller in place.
• d) The air-gap between the drive magnet and the impeller is too great, causing a loss of “magnetic lock”.
• NOTE: When adjusting the drive magnet on the pump motor shaft, place the drive magnet assembly as high as possible and still leave 1/16” clearance between the magnet and the underside of the top tray. The spacers on the motor bracket may be removed first for easier access.

Magnetic Lock Adjustment

1. Remove the pump motor assembly from the unit by loosening the (2) pump motor bolts with a 7/16 wrench. (To remove the left pump motor assembly on a D25, you will have to remove the (2) bolts that connect the frame to the top tray on the left side and raise the frame slightly to slide the motor out.)
2. With a 3/32 Allen Wrench, loosen the (2) set-screws on the drive magnet and raise the magnet. The magnet should be as close as possible to the evaporator cover without rubbing. Tighten the set-screws and replace the pump motor assembly.
