INTRODUCTION

Thank you for purchasing a Master-Bilt cabinet. This manual contains important instructions for installing, using, and
servicing a Master-Bilt BMG/TMG case. A parts list is included with this manual. Read all these documents carefully
before installing or servicing your equipment.

STORE CONDITIONS

The Master-Bilt BMG/TMG cases are designed to operate in the controlled environment of an air-conditioned store.
The store temperature should be at or below 75°F and a relative humidity of 55% or less. At higher temperature or
humidity conditions, the performance of these cases may be affected and the capacity diminished.

The Master-Bilt BMG/TMG should not be positioned where it is directly exposed to rays of sun or near a direct source
of radiant heat or airflow. This will adversely affect the case and will result in poor performance.

If this case is to be located against a wall, there should be at least 4” space between the wall and the back of the case.
This space will allow for the circulation of air behind the case, which will prevent condensation on the exterior surfaces.

NOTICE

Read this manual before installing your cabinet. Keep the manual and refer to it before

doing any service on the equipment. Failure to do so could result in personal injury or damage to the cabinet.

DANGER

Improper or faulty hook-up of electrical components on the refrigeration units can result in severe injury or
death.

All electrical wiring hook-ups must be done in accordance with all applicable local, regional or national
standards.

NOTICE

Installation and service of the refrigeration and electrical components of the ca binet must be performed by a
refrigeration mechanic and/or a licensed electrician.

The portions of this manual covering refrigeration and electrical components contain technical instructions intended
only for persons qualified to perform refrigeration and electrical work.
This manual cannot cover every installation, use or service situation. If you need additional information, call or write us:
