SAFETY
IMPORTANT SAFETY INSTRUCTIONS
Carefully read all safety messages in this manual. Learn how to operate the MD unit properly. Do not 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
DANGER: Carbon Dioxide (CO2) displaces oxygen.Exposure to a high concentration of CO2 gas causes tremors, which are followed rapidly by loss of consciousness and suffocation. If a CO2 gas leak is suspected, particularly in a small area, immediately ventilate the area before repairing the leak. CO2 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.Ifyou suspect CO2 may build up in an area, venting of the B-I-B pumps and / or CO2 monitors should be utilized.
QUALIFIED SERVICE PERSONNEL
WARNING: Only trained and certified electrical and plumbing technicians should service this unit. All wiring and plumbing must conform to national and local codes.
SHIPPING, STORAGE, AND RELOCATION
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 environment causes residual sanitizing solution or water remaining inside the unit to freeze, resulting in damage to internal components.
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.
Installation and Service Manual
SAFETY
GROUNDING IN STRUCTIONS
WARNING: Risk of electrical shock. Connect to a properly grounded outlet only.
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 electric 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 necessary, 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 appliance – 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, including 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 adjustment.
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.

INSTALLATION
UNIT INSTALLATION
1.Place the dispenser in the desired location.
2.Run the beverage lines and water lines (make sure to install the water connections to the proper inlets. Connection “A” comes from the procon pump and is your carbonated water supply and Connection “B” is your plain water supply. (Refer to plumbing diagrams.)
3.Install drain plumbing and insulate.
(See Drainage Options below)
4.Set flexible manifold for correct drink settings.
5.Turn water supply on to the dispenser. Water pressure should be between 40 and 55 psi. If not in-be-
tween those pressures proper measures must be taken to regulate them to correct settings.
6.Turn CO2 supply on to the dispenser. Each cold carb pump deck is furnished with a fixed regulator set at 75 psi. Ambient units need to be set between 90 and 100 psi.
7.Fill bin with ice.
8.Connect power supply.
9.Brix beverage valves.
10.Meet all code requirements.

ing above. Because the icemaker is flush with the front of the dispenser, some icemakers may overhang at the back of the dispenser.
4Drains - A separate drain line is required for the ice machine, in addition to a drain line for the ice/beverage dispenser.
5MD Series dispensers require an adapter kit to install a top-mounted icemaker. Contact your local Servend distributor for the correct adapter kit.

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 blocking 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.
Please refer to the instructions included in kit #5013822 for more information on how to install.

INSTALLATION
BAFFLE FOR MANITOWOC™ CUBERS
When installing a Manitowoc™ “S” series Ice Machine on a Servend MD-series dispenser, a baffle kit is required for proper installation. The baffle kit is designed to prevent ice from lying against the front of the ice machine, and melting down the front of the dispenser. There are two different baffle kits available from Servend. One kit is for the 30" wide “S” series ice machine, and the other kit is for the 22" wide “S” series ice machine.
These two Kits are available through your local Manitowoc Distributor. List prices may be subject to change without notification. Please call your local parts distributor for current pricing before ordering.
Ice Maker Baffle Installation:
1.Remove both front panels.
2.Examine the ice machine to see if the machine has four screws on the lower front plastic panels.
3.If there are screws, remove them from the countersunk 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.

BAFFLE FOR "Q" SERIES ICE MACHINES
1.Position baffle on top of water well with tab on the front and the other tab inside the water well.
2.Mount the baffle on the left side of the ice maker using the hole and screw provided.
MANUAL FILL LID FOR DISPENSERS WITH A CUBER
If you are top mounting your MD Series dispenser with a cuber, you will require a lid for the manual fill area at the top, front of the dispenser.
If you ordered a Servend dispenser and a cuber at the same time, the manual fill lid was included with the unit. The manual fill lid can be ordered from your local Servend distributor.

INSTALLATION
PLUMBING DIAGRAM LOCATION
The plumbing diagram is printed on a white vinyl label, usually located above the inlet tubes for syrup and later. The plumbing diagram label can be accessed by removing the splash panel of the dispenser. The plumbing diagram label explains which inlet coldplate fittings supply which dispenser valves and water manifolds.
On internal carb units the water supply must first be connected to the carbonator pump before plumbing to connection “A” shown on plumbing diagram. The carbonator pump deck must be within six feet of the dispenser for optimum performance.
