WARNING!
U
SE THIS APPLIANCE FOR ITS INTENDED PURPOSE AS DESCRIBED IN THIS MANUAL
When using electrical appliances, basic safety precautions should be followed, including the following:
• Use this appliance for its intended
purpose as described in this Owner
Manual.
• This cooler must be properly installed
and located in accordance with the
Installation Instructions.
• We strongly recommend that any
servicing be performed by a qualified
individual.
• Do not allow children to climb, stand, or
hang on the cooler. They could damage
the refrigerator and seriously injure
themselves.

Warning Child Safety!
Destroy carton, plastic bags, and any exterior wrapping material immediately after the cooler is
unpacked. Children should never use these items as toys. Cartons covered with rugs, bedspreads, plastic
sheets or stretch wrap may become airtight chambers and can quickly cause suffocation.
A child might suffocate if he crawls into a cooler to hide or play. Remove the door of a cooler when
not in use, even if you plan to discard the cooler. Many communities have laws requiring you to take
this safety precaution.
Small objects are a choke hazard to children.
CAREFULLY READ THESE INSTRUCTIONS. This manual provides instructions in how to best locate,
operate, and maintain this equipment.
It is recommended to keep this manual for any future reference.
Detailed Warranty Guidelines can be found on the Master-Bilt website.

DIRECTIONS FOR STORAGE AND HANDLING OF THE EQUIPMENT
STORAGE OF THE EQUIPMENT
If the equipment will be kept in storage, it is suggested to keep it in its original packing.
In case you need your equipment to be inactive for a long period of time after being used, verify that it
has been unplugged. After cleaning it thoroughly with a damp cloth, lukewarm water and neutral soap
and carefully drying it, cover it with a polyethylene film or similar waterproof material.
UNCRATING
The following procedure is recommended for uncrating the unit:
Remove the outer package by carefully cutting the banding and removing the cardboard box.
Inspect for concealed damage. Immediately file a claim with the freight carrier if there is damage.
Move your unit as close to the final location as possible before removing the wooden skid.
•••• www.master-bilt.com • Pg. 3 ••••
MOVING THE EQUIPMENT
The unit is shipped with casters to facilitate moving the unit into position.
Disconnect the power cord plug from the wall outlet. Remove product, clean, and dry the cooler.
Secure all loose items such as baskets and fix the lids by taping them securely in place to prevent
damage. In the moving vehicle, secure the cooler in an upright position and cover it to protect the
outside of the cabinet.
PLACING AND INSTALLING THE EQUIPMENT
T
HIS UNIT CANNOT BE INSTALLED IN ENVIRONMENTS WITH EXPLOSIVE GASES. THE EQUIPMENT IS
DESIGNED ONLY FOR INDOOR OPERATION
The unit must be located in an indoor environment.
For the correct performance of the refrigerating system, it is very important to leave at least 10 cm (4")
of free space both at the sides and back to allow proper air circulation.
.
ENERGY SAVINGS IDEAS
The cooler must be kept away from sources of heat and humidity including direct sunlight, toasters,
ovens, coffee warmers, other appliances condenser air discharge, infrared heaters, or other heat
generating appliances.
Product to be loaded should be at 32° - 40° F since the equipment is intended for maintaining a cool
product at load level rather than cooling a warm product
Keep the lids closed to avoid warm air and moisture getting into the cooler.
•••• www.master-bilt.com • Pg. 4 ••••
ELECTRICAL REQUIREMENTS
The power cord of this appliance is equipped with a 3-prong
(grounding) plug which mates with a standard 3-prong (grounding)
wall outlet to minimize the possibility of electric shock hazard from
this appliance.
The use of extension cords is not permitted and will void the
warranty.
Before connecting your equipment, check that the electrical data on
the data plate match your electrical output. If voltage varies by 10
percent or more, cooler performance may be affected. Operating the
cooler with insufficient power can damage the compressor. Such
damage is not covered under the warranty. If you suspect voltage is
high or low, consult your power company for testing.
To prevent the cooler from being turned off accidentally, do not plug unit into an outlet controlled by a
wall switch or pull cord.
Do not pinch, knot, or bend the power cord in any manner.

PRODUCT LOADING
The MTB30 series of units are not intended to be a pull down cooler and as such the product must be
loaded at their intended merchandising temperature.
Before loading products, allow the equipment to operate empty for at least four hours.

The temperature control is factory pre-set to provide satisfactory product storage products. However, the
temperature control is adjustable to provide a range of temperatures for your personal satisfaction. If a
colder temperature is desired, turn the control clockwise. Allow several hours for temperature to
stabilize between adjustments. The temperature control is located behind the access panel on the side of
the unit.
POWER FAILURE/COOLER FAILURE
Note: Do not open the cooler door unnecessarily if power to the cooler is off for several hours
If the cooler has stopped operating, see "Cooler does not run" in the Service Checklist Section of this

cooler continues to run.
Metal parts undergo expansion and contraction, as in hot water pipes. This is normal. Sound will level or disappear as cooler
continues to run.
Refrigerant (used to cool coolers) is circulating throughout the system. This is normal.
Level the cooler by putting wood or metal shims under art of the cooler.
