SERIAL NUMBER INFORMATION

The serial number of the milk cooler is located inside the unit on the left-hand side near the top on the wall.

Always have the serial number of your unit available when calling for parts or service. Also, retain proof of

purchase including the order date or your warranty will be voided.

This manual covers standard units only. If you have a custom unit, consult the customer service department

at the number listed in the back cover.

RECEIVING AND INSPECTING THE EQUIPMENT

Even though most equipment is shipped crated, care should be taken during unloading so the equipment is

not damaged while being moved into the building.

1. Visually inspect the exterior of the package and skid or container. Any damage should be noted and

reported to the delivering carrier immediately.

2. If damaged, open and inspect the contents with the carrier.

3. In the event that the exterior is not damaged, yet upon opening, there is concealed damage to the

equipment notify the carrier. Notification should be made verbally as well as in written form.

4. Request an inspection by the shipping company of the damaged equipment. This should be done

within 10 days from receipt of the equipment.

5. Be certain to check the compressor compartment housing and visually inspect the refrigeration

package. Be sure lines are secure and base is still intact.

6. Freight carriers can supply the necessary damage forms upon request.

7. Retain all crating material until an inspection has been made or waived.

8. Advise our customer technical support department of any filed damage claims with the carrier.

CONGRATULATIONS ON YOUR NEW COOLER

Note these instructions apply to all milk coolers. Installation of equipment may not exactly correspond to

your model.

INSTALLATION

1. AIR CIRCULATION

-The cooler should be placed in a warm, dry room, with suitable ventilation. Please make sure to avoid any

partition or objects that may stop the air flow. Please make sure there is enough space for air circulation to

the rear of the unit. Recommended space between the rear of the unit to the wall is at least 5 inches.

2. FOUNDATION

- Please make sure that the floor where the unit will be placed can support the total weight plus any other

contents that it may hold.

3. DO NOT PLACE NEAR HEAT

- Please make sure to avoid hot corners and locations near stoves.

- High ambient temperature will significantly reduce cooling efficiency.

4. INDOOR USAGE ONLY

- This unit is designed and tested for indoor use only. Never place the cooler in strong sunlight.

- Outdoor usage will void its warranty.

5. LEVELING

- Please make sure that the unit is level from the front to the back and side to side before placing it in service

6. STABILITY

-The cooler should always be placed on a stable surface with all casters level and the brakes set when in

use or it’s being stored in an accessible location

Service and Installation Manual

ELECTRICAL CONNECTION

The cooler must be connected to a NEMA 5-15 or 5-20 receptacle with the correct voltage/frequency, as

show on the nameplate. The standard for U.S is 115V/60Hz. Voltage variations of ±10% are acceptable.

Greater variations can damage the cooler, and in such cases the factory warranty is not valid. In the case of

extreme voltage variation, above or below the standard, your local supplier or utility company will be able to

advise you, what to do.

All wiring between the electrical panel and the unit must be done in accordance with the National Electric

Code and all state and local codes.

FOOD STORAGE

The cooler is only designed as a serving vehicle and is not suited to store cold food for extended periods of

time. In other words, only milk containers must be placed in the cooler. The cooler must not be filled beyond

the height limit of the included contents fill level line, or in cases where there is no such line, to within

100mm below the lid. This is to ensure the product temperature remains less than 40°F.

OPERATING INSTRUCTIONS

The temperature in the cooler is automatically regulated by a set thermostat.

The position of the cooler, the ambient temperature, the number of times the lid is opened and for how long

the lid is opened are all factors affect the temperature in the cooler. To assur e pr op er t em perat ur e regulation

do not place in the appliance in sunlight or near / adjacent to a heat-radiating surface.

If your cooler is fitted with a lock, the key should be kept out of the reach of children. If your new cooler is to

replace an older one, which is not in use any more, you should remove the lock mechanism on the old one,

before disposing it.

Do not throw items into the storage area. Failure to heed these recommendations could result in damage to

the

interior of the cabinet.

The factory setting for the temperature range is 34°F to 38° F which keeps your milk at a safe,

cold temperature.
