allow anyone to operate the unit without proper training and keep it in proper working condition.

Unauthorized modifications to the MD may impair function and/or safety and affect the life of the unit.

CARBON DIOXIDE WARNING

QUALIFIED SERVICE PERSONNEL

SHIPPING, STORAGE, AND RELOCATION

ADDITIONAL WARNINGS

Installation and start-up of this equipment should be done by a qualified service technician. Operation,

maintenance, and cleaning information in this manual are provided for the user/operator of the equipment.

Save these instructions.

DANGER: Carbon Dioxide (CO

) displaces oxygen. Exposure to a high concentration of CO

gas causes

tremors, which are followed rapidly by loss of consciousness and suffocation. If a CO

gas leak is

suspected, particularly in a small area, immediately ventilate the area before repairing the leak. CO

lines

and pumps should not be installed in an enclosed space. An enclosed space can be a cooler or small

room or closet. This may include convenience stores with glass door self serve coolers. If you suspect CO

may build up in an area, venting of the B-I-B pumps and / or CO

monitors should be utilized.

WARNING: Only trained and certified electrical and plumbing technicians should service this unit. All

wiring and plumbing must conform to national and local codes.

CAUTION: Before shipping, storing, or relocating this unit, syrup systems must be sanitized. After

sanitizing, all liquids (sanitizing solution and water) must be purged from the unit. A freezing environ-

ment causes residual sanitizing solution or water remaining inside the unit to freeze, resulting in

damage to internal components.

Installation and Service Manual

GROUNDING IN STRUCTIONS

SAFETY

This appliance must be grounded. In the event of malfunction or breakdown, grounding provides a

path of least resistance for electric current to reduce the risk of electric shock. This appliance is

equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug

must be plugged into an appropriate outlet that is properly installed and grounded in accordance

with all local codes and ordinances.

DANGER – Improper connection of the equipment-grounding conductor can result in a risk of elec-

tric shock. The conductor with insulation having an outer surface that is green with or without yellow

stripes is the equipment grounding conductor. If repair or replacement of the cord or plug is neces-

sary, do not connect the equipment-grounding conductor to a live terminal. Check with a qualified

electrician or serviceman if the grounding instructions are not completely understood, or if in doubt

as to whether the appliance is properly grounded. Do not modify the plug provided with the appli-

ance – if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

WARNING – When using electric appliances, basic precautions should always be followed, includ-

ing the following:

a) Read all the instructions before using the appliance.

b) To reduce he risk of injury, close supervision is necessary when an appliance is used near

children.

c) Do not contact moving parts.

d) Only use attachments recommended or sold by the manufacturer.

e) Do not use outdoors.

f) For a cord-connected appliance, the following shall be included:

• Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.

• Unplug from outlet when not in use and before servicing or cleaning.

• Do not operate any appliance with a damaged cord or plug, or after the appliance

malfunctions or is dropped or damaged in any manner. Return appliance to the nearest

authorized service facility for examination, repair, or electrical or mechanical adjust-

ment.

g) For a permanently connected appliance – Turn the power switch to the off position when

the appliance is not in use and before servicing or cleaning.

h) For an appliance with a replaceable lamp – always unplug before replacing the lamp.

Replace the bulb with the same type.

i) For a grounded appliance – Connect to a properly grounded outlet only. See Grounding

Instructions.

SAVE THESE INSTRUCTIONS

WARNING

Risk of electrical shock. Connect to a properly grounded outlet only.

Installation and Service Manual

1 Location - Avoid placing the dispenser and/or ice

machine near heat sources such as radiators, ov-

ens, refrigeration equipment and direct sunlight.

2 Clearances - Six inch (15.2 cm) clearance on all

sides of the icemaker is needed.

3 Front of icemaker to be flush with front of dis-

penser- The front of the icemaker should be flush

with the front of the dispenser, as shown in the draw-

ing above. Because the icemaker is flush with the

front of the dispenser, some icemakers may over-

hang at the back of the dispenser.

4 Drains - A separate drain line is required for the ice

machine, in addition to a drain line for the ice/bev-

erage dispenser.

5 MD Series dispensers require an adapter kit to

install a top-mounted icemaker. Contact your lo-

cal Servend distributor for the correct adapter kit.

INSTALLATION

TOP MOUNTED ICEMAKER REQUIREMENTS

NOTE: For full information about icemaker installation, including plumbing lines connections and

electrical requirements, see the icemaker installation manual.

ICE FLOW RESTRICTOR

Ice Flow Restrictor

For all Servend MD/MDH Series dispensers an ice flow

restrictor is available. This ice flow restrictor decreases

the amount of ice allowed to enter the ice chute by block-

ing a small area at the entrance of the dispenser chute.

This in turn restricts the flow of ice that is dispensed in to

your cup.

four screws on the lower front plastic panels.

3. If there are screws, remove them from the counter-

sunk holes on the front surface of the machine, save

the screws.

4. Install the deflector, using the four screws removed

in step three.

5. Four screws and two backing plates are in the kit.

6. If there are no screws on the ice machine (step 2),

pierce the thin plastic countersunk holes, install the

backing plates and install the deflector using the

screws from the kit.

7. Replace the front panels.
